Subject: [PATCH 008/446] SimpleChatTC: Skeleton to handle diff fields when
 streaming

Changed latestResponse type to an object instead of a string.
Inturn it contains entries for content, toolname and toolargs.

Added a custom clear logic due to the same and used it to replace
the previously simple assigning of empty string to latestResponse.

For now in all places where latestReponse is used, I have replaced
with latestReponse.content.

Next need to handle identifying the field being streamed and inturn
append to it. Also need to add logic to call tool, when tool_call
triggered by genai.

Subject: [PATCH 009/446] SimpleChatTC: Extract streamed field - assume only 1f
 at any time

Update response_extract_stream to check for which field is being
currently streamed ie is it normal content or tool call func name
or tool call func args and then return the field name and extracted
value.

Previously it was always assumed that only normal content will be
returned.

Currently it is assumed that the server will only stream one of the
3 supported fields at any time and not more than one of them at the
same time.

TODO: Have to also add logic to extract the reasoning field later,
ie wrt gen ai models which give out their thinking.

Have updated append_response to expect both the key and the value
wrt the latestResponse object, which it will be manipualted.

Previously it was always assumed that content is what will be got
and inturn appended.

Subject: [PATCH 010/446] SimpleChatTC: Avoid null content, Fix oversight wrt
 finish_reason

I was wrongly checking for finish_reason to be non null, before
trying to extract the genai content/toolcalls, have fixed this
oversight with the new flow in progress.

I had added few debug logs to identify the above issue, need to
remove them later. Note: given that debug logs are disabled by
replacing the debug function during this program's initialisation,
which I had forgotten about, I didnt get the debug messages and
had to scratch my head a bit, before realising this and the other
issue ;)

Also either when I had originally implemented simplechat 1+ years
back, or later due to changes on the server end, the streaming
flow sends a initial null wrt the content, where it only sets the
role. This was not handled in my flow on the client side, so a
null was getting prepended to the chat messages/responses from the
server. This has been fixed now in the new generic flow.

Switch oneshot handler to use AssistantResponse, inturn currenlty
only handle the normal content in the response.

TODO: If any tool_calls in the oneshot response, it is currently
not handled.

Inturn switch the generic/toplevel handle response logic to use
AssistantResponse class, given that both oneshot and the
multipart/streaming flows use/return it.

Inturn add trimmedContent member to AssistantResponse class and
make the generic handle response logic to save the trimmed content
into this. Update users of trimmed to work with this structure.

Subject: [PATCH 014/446] SimpleChatTC: twins wrt streamed response handling

As there could be failure wrt getting the response from the ai
server some where in between a long response spread over multiple
 parts, the logic uses the latestResponse to cache the response
as it is being received. However once the full response is got,
one needs to transfer it to a new instance of AssistantResponse
class, so that latestResponse can be cleared, while the new
instance can be used in other locations in the flow as needed.

Achieve the same now.

Subject: [PATCH 016/446] SimpleChatTC:tooljs: Trap console.log and store in
 new result key

The implementations of javascript and simple_calculator now use
provided helpers to trap console.log messages when they execute
the code / expression provided by GenAi and inturn store the
captured log messages in the newly added result key in tc_switch

This should help trap the output generated by the provided code
or expression as the case maybe and inturn return the same to the
GenAi, for its further processing.

Subject: [PATCH 018/446] SimpleChatTC: Cleanup initial/1st go toolcall flow

As output generated by any tool/function call is currently placed
into the TextArea provided for End user (for their queries), bcas
the GenAi (engine/LLM) may be expecting the tool response to be
sent as a user role data with tool_response tag surrounding the
results from the tool call. So also now at the end of submit btn
click handling, the end user input text area is not cleared, if
there was a tool call handled, for above reasons.

Also given that running a simple arithmatic expression in itself
doesnt generate any output, so wrap them in a console.log, to
help capture the result using the console.log trapping flow that
is already setup.

Subject: [PATCH 020/446] SimpleChatTC: More clearer description of toolcalls
 execution env

Should hopeful ensure that the GenAi/LLM will generate appropriate
code/expression as the argument to pass to these tool calls, to
some extent.

Try trap async promise failures by awaiting results of tool calling
and putting full thing in an outer try catch. Have forgotten the

So that when tool handler writes the result to the tc_switch, it
can make use of the same, to write to the right location.

NOTE: This also fixes the issue with I forgetting to rename the
key in js_run wrt writing of result.

+#### Mapping tool calls and responses to normal assistant - user chat flow
+
+Instead of maintaining tool_call request and resultant response in logically seperate parallel
+channel used for requesting tool_calls by the assistant and the resulstant tool role response,
+the SimpleChatTC pushes it into the normal assistant - user chat flow itself, by including the
+tool call and response as a pair of tagged request with details in the assistant block and inturn
+tagged response in the subsequent user block.
+
+This allows the GenAi/LLM to be aware of the tool calls it made as well as the responses it got,
+so that it can incorporate the results of the same in the subsequent chat / interactions.
+
+NOTE: This flow tested to be ok enough with Gemma-3N-E4B-it-Q8_0 LLM ai model for now.
+
+TODO: Need to think later, whether to continue this simple flow, or atleast use tool role wrt
+the tool call responses or even go further and have the logically seperate tool_call request
+structures also.

Subject: [PATCH 028/446] SimpleChatTC: Let user trigger tool call, instead of
 automatic

Instead of automatically calling any requested tool by the GenAi
/ llm, that is from the tail end of the handle user submit btn
click,

Now if the GenAi/LLM has requested any tool to be called, then
enable the Tool Run related UI elements and fill them with the
tool name and tool args.

In turn the user can verify if they are ok with the tool being
called and the arguments being passed to it. Rather they can
even fix any errors in the tool usage like the arithmatic expr
to calculate that is being passed to simple_calculator or the
javascript code being passed to run_javascript_function_code

If user is ok with the tool call being requested, then trigger
the same.

The results if any will be automatically placed into the user
query text area.

User can cross verify if they are ok with the result and or
modify it suitabley if required and inturn submit the same to
the GenAi/LLM.

Also ensure to add a newline at end of console.log messages

Subject: [PATCH 036/446] SimpleChatTC: Actual tool call implementations
 simplified

These no longer need to worry about

* setting up the console.log related redirection to capture
  the generated outputs, nor about
* setting up a dynamic function for executing the needed
  tool call related code

The web worker setup to help run tool calls in a relatively
isolated environment independent of the main browser env,
takes care of these.

One needs to only worry about getting the handle to the
web worker to use and inturn pass the need code wrt the
tool call to it.

* dont wait for the result from the tool call, as it will be got

* allow users of the tools manager to register a call back, which
  will be called when ever a message is got from the web worker
  containing response wrt previously requested tool call execution.

simplechat

* decouple toolcall response handling and toolcall requesting logic

* setup a timeout to take back control if tool call takes up too
  much time. Inturn help alert the ai model, that the tool call
  took up too much time and so was aborted, by placing a approriate
  tagged tool response into user query area.

* register a call back that will be called when response is got
  asynchronously wrt anye requested tool calls.
  In turn take care of updating the user query area with response
  got wrt the tool call, along with tool response tag around it.

Subject: [PATCH 038/446] SimpleChatTC: Web worker flow initial go cleanup

Had forgotten to specify type as module wrt web worker, in order
to allow it to import the toolsconsole module.

Had forgotten to maintain the id of the timeout handler, which is
needed to clear/stop the timeout handler from triggering, if tool
call response is got well in time.

As I am currently reverting the console redirection at end of
handling a tool call code in the web worker message handler, I
need to setup the redirection each time. Also I had forgotten
to clear the console.log capture data space, before a new tool
call code is executed, this is also fixed by this change.

TODO: Need to abort the tool call code execution in the web worker
if possible in future, if the client / browser side times out
waiting for tool call response, ie if the tool call code is taking
up too much time.

Subject: [PATCH 039/446] SimpleChatTC: Increase the sliding window context to
 Last4 QA

As the tool calling, if enabled, will need access to last few
user query and ai assistant responses (which will also include
in them the tool call requests and the corresponding results),
so that the model can build answers based on its tool call reqs
and got responses, and also given that most of the models these
days have sufficiently large context windows, so the sliding
window context implemented by SimpleChat logic has been increased
by default to include last 4 query and their responses roughlty.

Also update it to expect ChatMessageEx object

Update all users of add to follow the new syntax and semantic.

Subject: [PATCH 054/446] SimpleChatTC:Propogate toolcall id through tool call
 chain

Use HTMLElement's dataset to maintain tool call id along with
the element which maintains the toolname.

Pass it along to the tools manager and inturn the actual tool
calls and through them to the web worker handling the tool call
related code and inturn returning it back as part of the obj
which is used to return the tool call result.

Embed the tool call id, function name and function result into
the content field of chat message in terms of a xml structure

Also make use of tool role to send back the tool call result.
Do note that currently the id, name and content are all embedded
into the content field of the tool role message sent to the
ai engine on the server.

NOTE: Use the user query entry area for showing tool call result
in the above mentioned xml form, as well as for user to enter
their own queries. Based on presence of the xml format data at
beginning the logic will treat it has a tool result and if not
then as a normal user query.

The css has been updated to help show tool results/msgs in a
lightyellow background

also possible refinement wrt trapping, if needed, added as comment

all or allSettled to use or not is the question.

whether to wait for a round trip through the related event loop or
not is also a question.

+#### Related stuff
+
+Promise as well as users of promise (for now fetch) have been trapped wrt their then and catch flow,
+so that any scheduled asynchronous code or related async error handling using promise mechanism also
+gets executed, before tool calling returns and thus data / error generated by those async code also
+get incorporated in result sent to ai engine on the server side.
 
 #### ToDo
 
 WebFetch and Local web proxy/caching server
 
-Try and trap promises based flows to ensure all generated results or errors if any are caught
-before responding back to the ai model.
+Is the promise land trap deep enough, need to think through and explore around this once later.

As html can be malformed, xml ElementTree XMLParser cant handle
the same properly, so switch to the HtmlParser helper class that is

Currently a minimal skeleton to just start it out, which captures
only the body contents.

Subject: [PATCH 088/446] SimpleChatTC:SimpleProxy: Ensure CORS related headers
 sent always

Add a new send headers common helper and use the same wrt the
overridden send_error as well as do_OPTIONS

This ensures that if there is any error during proxy opertions,
the send_error propogates to the fetch from any browser properly
without browser intercepting it with a CORS error

 few types

Make the previously relatively generic flow wrt apiRequestOptions
settings into a fully generic reusable by others flow.

Rather had stopped short of it, when previously moved onto other
things at that time.

Subject: [PATCH 113/446] SimpleChatTC:ShowObjPropsEdit:Any depth trapping of
 ui setup

Maintain the current property hierarchy to its root over recursive
calls.

Allow callers to specify the props to be trapped using the prop
hierarchy.

Pass the prop hierarchy to the fTrapper.

This should allow one to trap any prop wrt its editing ui setup,
irrespective of whether it is a prop of the main object passed,
or a member of a child prop of the main object passed or so ...

Update the setting up of ChatHistoryInCtxt and ApiEndPoint to follow
the new semantic/flow.

Subject: [PATCH 114/446] SimpleChatTC:ShowObjPropsEdit:Any depth trapping of
 ui setup - t2

Fix up the oversights wrt any depth trapping flow

Remember to start the propWithTree being checked/trapped with :
to indicate the root of the prop hierarchy and also use : as sep
between the elements of the props hierarchy tree

Also had forgotten about the goof up possible with using in in a
condition statement to check for array to contain a entry of interest
in JS, fixed it now.

 and general

Had confused between js and python wrt accessing dictionary
contents and its consequence on non existent key. Fixed it.

Use different error ids to distinguish between failure in common
urlreq and the specific urltext and urlraw helpers.

Instead of simple concatenating of tool call id, name and result
now use browser's dom logic to create the xml structure used for
now to store these within content field.

This should take care of transforming / escaping any xml special
chars in the result, so that extracting them later for putting
into different fields in the server handshake doesnt have any
problem.

Subject: [PATCH 137/446] SimpleChatTC:Auto tool calling control to end user

Instead of enforcing always explicit user triggered tool calling,
now user is given the option whether to use explicit user triggered
tool calling or to use auto triggering after showing tool details
for a user specified amount of seconds.

NOTE: The current logic doesnt account for user clicking the buttons
before the autoclick triggers; need to cancel the auto clicks, if
user triggers before autoclick, ie in future.

 ### Tool Calling
 
-ALERT: The simple minded way in which this is implemented, it can be dangerous in the worst case,
-Always remember to verify all the tool calls requested and the responses generated manually to
-ensure everything is fine, during interaction with ai models with tools support.
+Given that browsers provide a implicit env for not only showing ui, but also running logic,
+simplechat client ui allows use of tool calling support provided by the newer ai models by
+end users of llama.cpp's server in a simple way without needing to worry about seperate mcp
+host / router, tools etal, for basic useful tools/functions like calculator, code execution
+(javascript in this case).
+
+Additionally if users want to work with web content as part of their ai chat session, Few
+functions related to web access which work with a included python based simple proxy server
+have been implemented.
+
+This can allow end users to use some basic yet useful tool calls to enhance their ai chat
+sessions to some extent. It also provides for a simple minded exploration of tool calling
+support in newer ai models and some fun along the way as well as occasional practical use
+like
+
+* verifying mathematical or logical statements/reasoning made by the ai model during chat
+sessions by getting it to also create and execute mathematical expressions or code to verify
+such stuff and so.
+
+* access content from internet and augment the ai model's context with additional data as
+needed to help generate better responses. this can also be used for
+  * generating the latest news summary by fetching from news aggregator sites and collating
+  organising and summarising the same
+  * searching for specific topics and summarising the results
+  * or so
+
+The tool calling feature has been tested with Gemma3N, Granite4 and GptOss (given that
+reasoning is currently unsupported by this client ui, it can mess with things)
+
+ALERT: The simple minded way in which this is implemented, it provides some minimal safety
+mechanism like running ai generated code in web workers and restricting web access to user
+specified whitelist and so, but it can still be dangerous in the worst case, So remember
+to verify all the tool calls requested and the responses generated manually to ensure
+everything is fine, during interaction with ai models with tools support.
 
 #### Builtin Tools
 
 The following tools/functions are currently provided by default
+
+##### directly in browser
+
 * simple_calculator - which can solve simple arithmatic expressions
+
 * run_javascript_function_code - which can be used to run some javascript code in the browser
   context.
-* fetch_web_url_raw - fetch requested url through a proxy server
-* fetch_web_url_text - fetch requested url through a proxy server
-  and also try strip the html respose of html tags and also head, script, style, header,footer,... blocks.

+Currently the ai generated code / expression is run through a simple minded eval inside a web worker
 mechanism. Use of WebWorker helps avoid exposing browser global scope to the generated code directly.
 However any shared web worker scope isnt isolated. Either way always remember to cross check the tool
 requests and generated responses when using tool calling.
 
-fetch_web_url_raw/text and family works along with a corresponding simple local web proxy/caching
-server logic, this helps bypass the CORS restrictions applied if trying to directly fetch from the
-browser js runtime environment. Depending on the path specified wrt the proxy server, if urltext
-(and not urlraw), it additionally tries to convert html content into equivalent text to some extent
-in a simple minded manner by dropping head block as well as all scripts/styles/footers/headers/nav.
-* the logic does a simple check to see if the bundled simpleproxy is running at specified fetchProxyUrl
-  before enabling fetch web related tool calls.
-* The bundled simple proxy can be found at
-  * tools/server/public_simplechat/local.tools/simpleproxy.py
-  * it provides for a basic white list of allowed domains to access, to an extent
-  * it tries to mimic the client/browser making the request to it by propogating header entries like
-    user-agent, accept and accept-language from the got request to the generated request during proxying
-    so that websites will hopefully respect the request rather than blindly rejecting it as coming from
-    a non-browser entity.

Subject: [PATCH 144/446] SimpleChatTC:ToolCall:SearchWebText using UrlText

Initial go at implementing a web search tool call, which uses the
existing UrlText support of the bundled simpleproxy.py.

It allows user to control the search engine to use, by allowing
them to set the search engine url template.

The logic comes with search engine url template strings for
duckduckgo, brave, bing and google. With duckduckgo set by default.

Subject: [PATCH 145/446] SimpleChatTC:ToolCallWeby: Cleanup the toolweb module
 flow

Avoid code duplication, by creating helpers for setup and toolcall.

Also send indication of the path that will be used, when checking
for simpleproxy.py server to be running at runtime setup.

Subject: [PATCH 147/446] SimpleChatTC:ToolCallResponseTimeout: Allow end user
 to control

Moved it into Me->tools, so that end user can modify the same as
required from the settings ui.

TODO: Currently, if tc response is got after a tool call timed out
and user submitted default timed out error response, the delayed
actual response when it is got may overwrite any new content in
user query box, this needs to be tackled.

Subject: [PATCH 154/446] SimpleChatTC:SimpleProxy: once in a bluemoon
 transformed bearer

instead of using the shared bearer token as is, hash it with
current year and use the hash.

keep /aum path out of auth check.

in future bearer token could be transformed more often, as well as
with additional nounce/dynamic token from server got during initial
/aum handshake as also running counter and so ...

NOTE: All these circus not good enough, given that currently the
simpleproxy.py handshakes work over http. However these skeletons
put in place, for future, if needed.

TODO: There is a once in a bluemoon race when the year transitions
between client generating the request and server handling the req.
But other wise year transitions dont matter bcas client always
creates fresh token, and server checks for year change to genrate
fresh token if required.

Subject: [PATCH 155/446] SimpleChatTC:ToolTemp and ChatShow

Add a new role ToolTemp, which is used to maintain any tool call
response on the client ui side, without submitting it to the server
ie till user or auto submit triggers the submitting of that tool
call response.

When ever a tool call response is got, create a ToolTemp role based
message in the corresponding chat session. And dont directly update
the user query input area, rather leave it to the updated simplechat
show and the new multichatui chat_show helper and inturn whether the
current chat session active in ui is same as the one for which the
tool call response has been recieved.

TODO: Currently the response message is added to the current
active chat session, but this needs to be changed by tracking
chatId/session through the full tool call cycle and then adding
the tool call response in the related chat session, and inturn
updating or not the ui based on whether that chat session is
still the active chat session in ui or not, given that tool call
gets handled in a asynchronous way.

Now when that tool call response is submitted, promote the equiv
tool temp role based message that should be in the session's chat
history as the last message into becoming a normal tool response
message.

SimpleChat.show has been updated to take care of showing any
ToolTemp role message in the user query input area.

A newer chat_show helper added to MultiChatUI, that takes care of
calling SimpleChat.show, provided the chat_show is being requested
for the currently active in ui, chat session. As well as to take
care of passing both the ChatDiv and elInUser. Converts users of
SimpleChat.show to use MultiChatUI.chat_show

Subject: [PATCH 156/446] SimpleChatTC:ToolCallErrPath:ToolTemp and
 MultiChatUIChatShow

Update the immidiate tool call triggering failure and tool call
response timeout paths to use the new ToolTemp and MultiChatUI
based chat show logics.

Actual tool call itself generating errors, is already handled
in the previous commit changes.

Subject: [PATCH 161/446] SimpleChatTC:Reasoning: Cleanup the initial go

Rather simplify and make the content_equiv provide a relatively
simple and neat representation of the reasoning with content and
toolcall as the cases may be.

Also remove the partial new para that I had introduced in the
initial go for reasoning.

Subject: [PATCH 165/446] SimpleChatTC:MultiChatUI:ChatShow cleanup of Initial
 skeleton

Fix up the initial skeleton / logic as needed.

Remember that we are working with potentially a subset of chat
messages from the session, given the sliding window logic of
context managing on client ui side, so fix up the logic to use
the right subset of messages array and not the global xchat
when deciding whether a message is the last or last but one,
which need special handling wrt Assistant (with toolcall) and
Tool (ie response) messages.

Moving tool call ui setup as well as tool call response got ui
setup into ChatShow of MultiChatUI ensures that switching between
chat sessions handle the ui wrt tool call triggering ui and tool
call response submission related ui as needed properly.

Rather even loading a previously auto saved chat session if it had
tool call or tool call response to be handled, the chat ui will be
setup as needed to continue that session properly.

Subject: [PATCH 169/446] SimpleChatTC:ShowMessage: containers, role, contents

Seperate out the message ui block into a container containing
a role block and contents container block.

This will allow themeing of these seperately, if required.
As part of same, currently the role has been put to the side
of the message with vertical text flow.

Subject: [PATCH 173/446] SimpleChatTC:UICleanup: WordBreaks, Print avoid side
 vertical

Define rules to ensure that chat message contents wrap so as to
avoid overflowing beyond the size of the screen being viewed.

The style used for chat message role to be placed with vertical
oriented text adjacent to the actual message content on the side
seems to be creating issue with blank pages in some browsers,
so avoid that styling when one is printing.

So mention that may be ai can send complex objects in stringified

do it, but no harm is hinting.

Subject: [PATCH 179/446] SimpleChatTC:DataStore:Eagerness to Wrong JSON
 conversions

In the eagerness of initial skeleton, had forgotten that the
root/generic tool call router takes care of parsing the json string
into a object, before calling the tool call, so no need to try
parse again. Fixed the same.

Hadnt converted the object based response from data store related
calls in the db web worker, into json string before passing to the
generic tool response callback, fixed the same.

- Rather the though of making the ChatMsgEx.createAllInOne handle
string or object set aside for now, to keep things simple and
consistant to the greatest extent possible across different flows.

And good news - flow is working atleast for the overall happy path
Need to check what corner cases are lurking like calling set on
same key more than once, seemed to have some flow oddity, which I
need to check later.

Also maybe change the field name to value from data in the response
to get, to match the field name convention of set. GPT-OSS is fine
with it. But worst case micro / nano / pico models may trip up, in
worst case, so better to keep things consistent.

Subject: [PATCH 189/446] SimpleChatTC:Seperate out actual nw handshake -
 initial go

move the actual chat handshake with ai server into a seperate code
to an extent.

also initial anchor to trap handshake http error responses

Rather come to think of it, its better to move this into SimpleChat
class.

Use finally to ensure any needed cleanup for handle_user_submit
occurs within itself.

Subject: [PATCH 198/446] SimpleChatTC:Pdf2Text: cleanup initial go

Make the description bit more explicit with it supporting local
file paths as part of the url scheme, as the tested ai model was
cribbing about not supporting file url scheme. Need to check if
this new description will make things better.

Convert the text to bytes for writing to the http pipe.

Ensure CORS is kept happy by passing AccessControlAllowOrigin in
header.

Subject: [PATCH 203/446] SimpleChatTC:TC Result truncating only if needed

As I was seeing the truncated message even for stripped plain text
web acces, relooking at that initial go at truncating, revealed
a oversight, which had the truncation logic trigger anytime the
iResultMaxDataLength was greater than 0, irrespective of whether
the actual result was smaller than the allowed limit or not,
thus adding that truncated message to end of result unnecessarily.
Have fixed that oversight

Also recent any number of args based simpleprox handshake helper
in toolweb seems to be working (atleast for the existing single
arg based calls).

Subject: [PATCH 209/446] SimpleChatTC:SimpleProxy: Use urlvalidator

Add --allowed.schemes config entry as a needed config.

Setup the url validator.

Use this wrt urltext, urlraw and pdf2text

This allows user to control whether local file access is enabled
or not. By default in the sample simpleproxy.json config file
local file access is allowed.

Added logic to help get a file from either the local file system
or from the web, based on the url specified.

Update pdfmagic module to use the same, so that it can support
both local as well as web based pdf.

Bring in the debug module, which I had forgotten to commit, after
moving debug helper code from simpleproxy.py to the debug module

Subject: [PATCH 223/446] SimpleChatTC: ToolCalling enabled, Sliding window
 adjust

Chances are for ai models which dont support tool calling, things
will be such that the tool calls meta data shared will be silently
ignored without much issue.

So enabling tool calling feature by default, so that in case one
is using a ai model with tool calling the feature is readily
available for use.

Revert SlidingWindow ChatHistory in Context from last 10 to last 5
(2 more then origianl, given more context support in todays models)
by default, given that now tool handshakes go through the tools
related side channel in the http handshake and arent morphed into
normal user-assistant channel of the handshake.

Subject: [PATCH 227/446] SimpleChatTC:WebTools: urltext-tag-drops python side
 - skel

Rename search-drops to urltext-tag-drops, to indicate its more
generic semantic. Rather search drops specified in UI by user
will be mapped to urltext-tag-drops header entry of a urltext
web fetch request.

Implement a crude urltext-tag-drops logic in TextHtmlParser.
If there is any mismatch with opening and closing tags in the
html being parsed and inturn wrt the type of tag being targetted
for dropping, things can mess up.

Subject: [PATCH 228/446] SimpleChatTC:WebTools:UrlText:HtmlParser: tag drops -
 refine

Update the initial skeleton wrt the tag drops logic

* had forgotten to convert object to json string at the client end
* had confused between js and python and tried accessing the dict
  elements using . notation rather than [] notation in python.
* if the id filtered tag to be dropped is found, from then on
  track all other tags of the same type (independent of id),
  so that start and end tags can be matched. bcas end tag call
  wont have attribute, so all other tags of same type need to
  be tracked, for proper winding and unwinding to try find
  matching end tag
* remember to reset the tracked drop tag type to None once matching
  end tag at same depth is found. should avoid some unnecessary
  unwinding.
* set/fix the type wrt tagDrops explicitly to needed depth and
  ensure the dummy one and any explicitly got one is of right type.

Tested with duckduckgo search engine and now the div based unneeded
header is avoided in returned search result.

Subject: [PATCH 232/446] SimpleChatTC:FetchPdfAsText: Renamed function call

Some ai's dont seem to be prefering to use this direct helper
provided for fetching pdf as text, on its own. Instead ai (gptoss)
seems to be keen on fetching raw pdf and extract text etal, so now
renaming the function call to try and make its semantic more
readily obivious hopefully.

It sometimes (not always) seem to assum fetch_web_url_text, can
convert pdf to text and return it. Maybe I need to place the
specific fetch pdf as text before the generic fetch web url text
and so...

With the rename, the pdf specific fetch seems to be getting used
more.

Have main classes defined independent of and away from runtime flow

Move out the entry point including runtime instantiation of the
core Me class (which inturn brings other class instances as neede)
into its own main.js file.

With this one should be able to import simplechat.js into other
files, where one might need the SimpleChat or MultiChat or Me class
definitions.

Subject: [PATCH 236/446] SimpleChatTC:MeInTools: WebWorkers in Me

Given that Me is now passed to the tools logic during setup, have
the web worker handles in Me itself, instead of in tool related
modules.

Move setup of web worker related main thread callbacks, as well as
posting messages directly to these main thread callbacks, into Me.

Subject: [PATCH 237/446] SimpleChatTC:Rather bring in Tools Class

So that all tools related management logic sits in tools module
itself, but is accessible from Me by having a instance of Tools.

The Workers moved into Tools class.

The tc_switch moved into Tools class.

The setup_workers, init, meta and tool_call moved into Tools class.

Subject: [PATCH 238/446] SimpleChatTC:ToolsManager: Instantiate in Me and Use

Rename Tools to ToolsManager to convey its semantic better.

Move setup of workers onmessage callback as well as directly passing
result to these callbacks into ToolsManager.

Now that Workers have been moved into ToolsManager, and ToolsManager
has been instantiated as a member of Me, use the same in place of
prev workers of Me.

Subject: [PATCH 239/446] SimpleChatTC:ToolsManager: Cleanup inc delayed direct
 posting

Me.tools.toolNames is now directly updated by init of ToolsManager

The two then in the old tools.init was also unneeded then also as
both could have been merged into a single then, even then. However
with the new flow, the 1st then is no longer required.

Also now the direct calling of onmessage handler on the main thread
side wrt immidiate result from tool call is delayed for a cycling
through the events loop, by using a setTimeout.

No longer expose the tools module throught documents, given that
the tools module mainly contains ToolsManager, whose only instance
is available through the global gMe.

Move the devel related exposing throught document object into a
function of its own.

Subject: [PATCH 240/446] SimpleChatTC:TrackToolCalls:helps ignor delayed
 response, if reqd

Add a pending object which maintains the pending toolcallid wrt
each chat session, when ever a tool call is made.

In turn when ever a tool call response is got cross check if its
toolcallid matches that in the pending list. If so accept the
tool call response and remove from pending list. If not just
ignore the response.

NOTE: The current implementation supports only 1 pending tool call
at any time.

NOTE: Had to change from a anonymous to arrow function so as to
be able to get access to the ToolsManager instance (this) from
within the function. ie make use of lexical binding semantic of
arrow functions.

Subject: [PATCH 247/446] SimpleChatTC:XmlFiltered: Use re with heirarchy of
 tags to filter

Rename xmltext to xmlfiltered.

This simplifies the filtering related logic as well as gives more
fine grained flexibility wrt filtering bcas of re.

 fetch_html_text

To make it easier for the ai model to understand that this works
mainly for html pages and not say xml or pdf or so. For those
one needs to use other explict tool calls provided like fetchpdftext
or fetchxmltext or so

The server service path renamed from urltext to htmltext.

 done

Pass a list to keep track of the numbering at different depths
as well as to delay incrementing the numbering to the last min

Switch from empty strings or empty list and so to undefined.

undefined will be treated by Javascript and JSON to mean, not even
instantiated and also dont instantiate the same

Subject: [PATCH 257/446] SimpleChatTC:NSChatMessage class driven wrt
 ChatMessageEx

NSChatMessage implements the undefined based flow and provides
helpers to check if any of the field like content or reasoning
or tool_calls is available in the chat message or not.

It also provides helpers to get the corresponding fields.

ChatMessageEx updated to make use of NSChatMessage.

Remove the load from disk support that was previously retained
wrt the old on-disk-storage format for the chat session messages.

Make a note to allow non ai server handshake roles to be maintained
wrt NSChatMessage. Add helper to cross check if a message belongs
to such temp roles or not.

Update SimpleChat class to make use of the new NSChatMessage based
needed flow.

Subject: [PATCH 260/446] SimpleChatTC:NSChatMessage with tool response/result
 fields

Add a new static helper to create a ChatMessageEx for a given
tool response data.

Use the same when storing tool response in the chat session msgs
list.

This inturn avoids the need for creating a xml string with all
the fields corresponding to tool response. So also no need to
extract the individiual tool response fields from the all-in-one
xml string and populate the tool response fields in the network
structure equivalent ns data structure, when recent_chat_ns is
called.

Subject: [PATCH 261/446] SimpleChatTC:NSChatMessage:ToolResponse show handling

Given that the user query box no longer includes the special xml
string wrt tool response data (TOOL.TEMP ROLE), so now instead set
a special attribute to indicate that user query/input box is
maintaining a tool response.

For regular Tool responses in the chat session, now show the tool
call id and tool name before the tool response data (ie content
field).

Currently the logic doesnt allow user to send a empty message to
ai, during their term. Previously this path wasnt directly alerting
the end user. Now it informs the end user using placeholder property
so they can see the alert, while also ensuring that once user enters
something, the alert wont interfere.

The logic takes care of saving any original placeholder, so that
the same is restored, when user switches sessions.

Subject: [PATCH 267/446] SimpleChatTC:Vision: Prepare NSChatMessage for Text
 &| Image

Avoid directly accessing content field, from any place other than
where it is absolutely requried.

Add a bOverwrite field to the content_adj helper, so that one can
overwrite instead of appending passed content to whats already in.

* this is currently used only wrt
  * promote_tooltemp helper
  * trim garbage helper
* the oneshot could ideally use overwriting, but currently
  not doing as this flow will occur only once per message

Add a image_url field for the image url with image data in dataurl
format with base64 encoded image data.

Subject: [PATCH 274/446] SimpleChatTCRV:Vision:Show user image selection in
 btn

Add a new helper to create a file type input which includes a btn
with image. Use same wrt the user image selection button.

Update button creation helper to show innerText only if the newly
added innerHTML arg is undefined.

When ever user makes a image selection, the image will be shown
in the input-filetype-image-button. In turn when the same is
submitted to ai engine server, the image will be cleared.

Subject: [PATCH 276/446] SimpleChatTCRV:Vision: DataUrl helpers

Move all dataUrl handling into helper functions.

So that its manipulation is done in a controlled manner, as well as
in future, changes to the semantic can be easily carried out by
updating the helper functions suitably and inturn updating the caller
as needed.

For now avoid push and pop and work with 0th index directly, given
that currently the logic is setup for handling only a single image
with the ai model. This keeps things simple. It can be changed if
required in future easily.

Subject: [PATCH 286/446] SimpleChatTCRV: Response handling try catch, update
 errors

Had forgotten to move the one shot resp into try catch before.
Fixed it. Ensure both oneshot multipart resp try catch

Add some todos for later.

Add a new check wrt response being normal or a error related one
ie the content is actually a error message.

Subject: [PATCH 290/446] SimpleChatTCRV:CMPopOver:Relative positioning - P1

Use position fixed followed by using position-area so that one
can use anchor passed through showPopover.

Avoid the hidePopover from mouseLeave, because as the mouse moves
over the poped up popover ui, the mouseLeave will be called on
the chat message block/container. And that would have closed the
popover and inturn mouseEnter would have got called on ChatMsg,
given now with the popover hidden, the ChatMsg block is directly
accessible. So this leads to twinkling / toggling ie continues
show/hide of the popover.

Inturn in mouseEnter itself decide when to close the previous
popover (ie if the chatmessage id is different from what it was
before).

 adjacent messages

Rename to get_chatmessage_index.

Return the index of the chatmessage deleted.

Add a scroll element into view helper.

Now the UniqId wrt the ChatMessage is stored as a attribute
wrt the corresponding chatmessage block. And same used wrt
scrolling after deleting messages.

When a chat message is deleted, previously the screen would have
moved to last message in the chat session, now it tries to remain
wrt adjacent messages on the screen.

Subject: [PATCH 298/446] SimpleChatTCRV:Cleanup:Delete and Chat UI suitable
 update

If deleting a non last (and non just before last) message, then
just directly remove the corresponding chat message block from the
ChatSession UI and be done with it.

However if deleting the last (or just before last) message, then
one needs to decide on whether tool call edit/trigger ui is shown
or removed and so... and similarly wrt tool response edit/submit.

Subject: [PATCH 302/446] SimpleChatTCRV:Cleanup:Distinguish btw uiremove &
 del_uiupdate

Needed as some places we require to delete the chat message as
well as update the corresponding ui block.

And in other places we require to just remove the ui block from
chat session ui and not the underlying chat message from chat history.

Change ui updateprev appendlast to use the ui remove logic.

Subject: [PATCH 305/446] SimpleChatTCRV:UI Flow cleanup plus

SC.add discards any temp role message and not just tool temp msg

New SC.add_smart which either adds a new message to the chat session
or replaces existing last message in the chat session, based on same
role or different, given that the chat session cant have the same
role type chat message occuring adjacent in it. Inturn rename MCUI
chatmsg_add_uishow to chatmsg_addsmart_uishow and use add_smart

* helps wrt trying to rerun a tool call with modified args or so.
  Rather prev discard temp role messages in SC.add not good enough
  as uniqId will change in its case.
  Helps avoid adding duplicate ToolTemp messages in chat session ui

* can help if loading a prev chat session which ended in a user
  message without a ai response. User can type in a new message
  and continue that old chat session, with the new message, replacing
  the old user message as well as initiating handshake with ai server
  in a proper manner.

Replace MCUI chatmsg_ui_updateprev_appendlast with chatmsg_ui_refresh
which is a more generic flow, which takes care of updating the ui as
needed irrespective of if the specified set of messages are already
in the chat session ui or not. Also allows the caller to control how
many messages at the end need to be refreshed wrt ui.

Subject: [PATCH 307/446] SimpleChatTCRV:UICleanup: Use chat_uirefresh not
 chat_show

Rename chatmsg_ui_refresh to chat_uirefresh.

Even in case of the delete path and inturn deleting one of the last
two messages in a chat session, now use the generified chat uirefresh
logic instead of the chat_show full session refresh / recreation of
the session ui

Inturn to make the uirefresh really generic and usable in all cases
including above case, now take care of clearing the tool call edit
/ trigger at the beginning, so that the last 2 messages decide in
turn whether to show a tool call edit/trigger ui or not, as well as
the tool call response edit / submit ui.

Demote the Popover related mouse event trapping related logs to

Avoid using brute force chat_show instead use only the optimal
chat_uirefresh wrt all paths in handle_user_submit, rather had

Subject: [PATCH 311/446] SimpleChatTCRV:UICleanup: User Input area one bunch
 of clenaup

ui_reset_userinput now resets role associated with user input to
user always.

chat_show now does a full on ui_reset_userinput, and thus inturn
session switching now force cleans up User Input area, state and
associated data (like dataURLs) with chat_show->ui_reset_userinput.

UIRefresh helper does a partial ui_reset_userinput thus cleaning
up the user input state. Inturn given that addsmart_uishow calls
uirefresh, so avoid calling partial ui_reset_userinput after call
to addsmart_uishow.

show_message now sets user input area role to either ToolTemp or
User (all cases other than ToolTemp).

Have a common 1vmin radius wrt buttons in general and chat messages.

While the input area and its buttons have more rounded look.

Force a minimum height wrt the buttons in general, while ensuring
that the popover menu buttons tightly fit the content/icons in them.

Move the heading, sessions list and system prompt into a details
block so that user can hide them if required.

avoid the borders around chat message blocks and the chat message
role blocks within them, instead go for a subtle box shadow.

Use gradiants wrt heading, as well as chat message role based color
codings.

Update both the normal/screen view as well as the print view wr
above.

Subject: [PATCH 316/446] SimpleChatTCRV:UICleanup: PopOverTO, buttonBorder,
 Restore, Usage

PopOver menu now auto closes, if user doesnt interact with it, for
a predefined timeout period.

Change the button border color, which seems to make it more pleasent
with current backgrounds at different places.

Update usage note wrt vision and click to toggle wrt title area.

Make the restore / load session block into a details based block.
Also place it into the parent div immidiately, but in hidden state.
Inturn only if a corresponding entry found in the db, create the
button for loading, as well as unhide it. This ensures that the
restore block's position|order doesnt change in the set of ui
elements wrt usage,restore,settings-info.

Subject: [PATCH 317/446] SimpleChatTCRV:UICleanup: Scrollbar, role gradiants,
 textarea, ...

Reduce fullbody height by a tiny bit so that everything fits within
the overall height of the screen available, without needing a dummy
no use vertical scrollbar for full body. Rather its hardcoded for
now, in a sense, need to look into all elements competing for vertical
space and see how to make this auto adapt responsively, if there is
any subtle issue beyond me going beyond 100vh.

Set scrollbar in general to thin and minimal contrast subdued look.

Change user gradiant to blue hue, also add a subtle whitish hue based
gradiant to assistant chat messages. Also make trimmed content bgnd
a gradiant.

Wrt print media target, instead of trying to change the body color
directly, use the global variable added for same, so that other elements
also adjust suitably wrt the change like gradiants merging seemlessly
into the changed overall background and so.

Allow the input textarea to grow vertically to an extent, while still
ensuring that it doesnt cross a limit which could lead to additional
full page scrollbar showing up.

Add a border-radius by default across elements. In turn add padding
wrt toolcall details block so that things dont get cutoff and appear
proper.

 SlidingWindow info

Allow AutoCreated Object Properties Editing UI to be themed to an
extent by assigning a id to the top level element, which is based
on the legend specified.

Use the same to add inline padding as well as adjust border radius
wrt the elements within, for the Settings ui. And min height and
border width wrt input, select and buttons within.

Similarly for the default Usage,Restore and SettingsInfo summary
titles, avoid border-radius.

Show the string representation of the sliding window selected.

Add some padding to system prompt input.

Subject: [PATCH 320/446] SimpleChatTCRV:UICleanup+: Fix oversight wrt Auto
 ObjPropsEdit

Had forgotten to use ${} for variable within a literal template
string.

Had forgotten to use the full hierarchy of props when setting the
id of elements, which is useful to map a label to a button and so.
This would have led to the wrong button being clicked when a label
with duplicated id was clicked. Ie if two different objects within
a object, have properties/fields with the same name, then previously
this would have led to a bunch of labels and buttons or so having
the same id, bcas their hierarchy was not being accounted for. This
is fixed now.

Subject: [PATCH 322/446] SimpleChatTCRV:Sessions++ button take two: normal
 html + js + css

Now use javascript to trap the button click and inturn change css
class to hide or show the corresponding div.

This moving away from details with summary being the top level
title + buttons block, avoids the warning wrt non standard use of
details element, as well as gives a clear icon to end users wrt
toggling the sessions+systemprompt block.

Subject: [PATCH 324/446] SimpleChatTCRV:UICleanup: ToolCall trigger and
 UserInput block

Add better visual cues wrt the tool call trigger block and the
user input block, and inturn remove the now unneeded horizontal
seperation line between chat messages block and the tool call
trigger block.

Bring in the user role color gradient to the full user input block

Change the TEMP roles to use -TEMP instead of .TEMP suffix, so
that role based css rules get applied without any complexity
that may inturn not get applied.

Avoid extra newlines in the err message returned by the tool call
workers. Given that now there is a proper tool call response
sent back to the ai backend/server, without using user and ai
text content block itself to maintain the tool call and its
response info (which is what this client was doing initially
and so more spacing was added to important parts to bring it
into better focus, just in case).

Subject: [PATCH 325/446] SimpleChatTCRV:UICleanup:Popover Firefox work around

As firefox doesnt seem to currently support anchor based relative
positioning of the popover, so explicitly set the position of the
popover.

Also reposition the popover to be in the bottom right corner rather
than the previous top center position.
* Rather updated position-area css property ensures this automatically
  wrt chrome browsers.
* while for firefox the explicit code that is added is needed.

NOTE: Had added that id, just in case firefox was goofing up bcas of
the element not having unique id or so, either way the firefox issue
is unrelated and more fundamental lack of support for now.

Subject: [PATCH 330/446] SimpleChatTCRV:MultipleImages: Icon only buttons

Instead of having texts submit and image, replace them with equiv
unicode icons.

Adjust the size of these buttons to be smaller, given that now they
only contain icons in them.

Switch from btn+inputfile+img to btn+inputfile wrt image loading btn
given that the image will be shown in seperate dynamically created
images in the user in div.

Subject: [PATCH 331/446] SimpleChatTCRV:MultipleImages:Update ChatMessage++
 wrt same

Now NSChatMessage inturn ChatMessageEx, ... have been updated
to maintain a array of image data instead of a single image.

Inturn the ShowMessage as well as submit logics have been updated
to account for multiple images.

Also fix a oversight from previous commit, where when pushing new
image, I had forgotten to remove the old logic, which would have
always updated the 0th image data in the array.

syncd with the user collor. However the tool call color is left
bit odder, to ensure user sight goes there for validating and
triggering.

Subject: [PATCH 336/446] SimpleChatTCRV:UIClean: Avoid wip popover anchor
 position mech

Instead use the explicit positioning, which was already added to
support firefox, given that firefox still doesnt support anchor
based positioning.

Also move the popover to top of the chat message bubble/block,
instead of the bottom area. This ensures that the popover isnt
butting heads with the tool call trigger or user input blocks.

Subject: [PATCH 338/446] SimpleChatTCRV:ToolCall Ai - Decouple SimpleChat from
 Me a bit

Had a custom struct for parts of Me needed by SimpleChat, and inturn
that need to be controlled when starting a independent parallel ai
session. For now if chat streaming is used or not and tools is enabled
or not is allowed to be explicitly controlled when handle_chat_hs is
called.

Inturn when toolai triggers the parallel ai session, it disables
tools calling support wrt this child/external ai tool call. Else
even the external ai session may end up triggering tool call wrt
external ai for the same job and thus get into a infinite recursive
loop.

Also
* update the toolai meta data a bit.
* increase time allowed for toolcall to return a response, especially
  usefull for external_ai tool call.

Cleanup some old notes and update readme in general.

Subject: [PATCH 339/446] SimpleChatTCRV:DivStream: Allow predetermined div for
 streamd resp

This will help ensure that switching sessions etal wont lead to
loosing handle to sessions that one exited from, with additional
logic to be added later.

Rather I am thinking, maybe it may make more sense to dynamically
pick the currently active chat sessions latestResponse field to
inturn show into a div element at end of the elDivChat.

On thinking further, maybe making elDivStream into elDivStreams
with seperate div for each session is the better thing, as the
SC.handle_response will be able to update its corresponding div
and the session switch can link the currently visible session's
div to be mapped to elDivChat.

NOTE: Rather this commit in itself should take care of the current
normal flow, which wont allow user to switch sessions when a tool
call or handshake with server is pending. However in future if
I want the ui to be freely switched independent of if a tool call
or server handshake is active, then I need the logic mentioned in
previous para.

Subject: [PATCH 341/446] SimpleChatTCRV:DivStreams: Why missing - still a
 mystry

Sometimes the session specific DivStream seems to be missing from
DivChat. Explicitly spliting the remove and append just for the
heck of it didnt help. So also have used try-catch-finally to
ensure it gets added back even if its not already in there, by
not allowing removeChild failure to bypass append etal.

Retaining this here just for the heck of it. WIll be switching
to the appendChild only flow (given it automatically moves the
node, as needed).

Subject: [PATCH 342/446] SimpleChatTCRV:DivStreams: Prepared for switching in
 middle

Missing DivStream caught. Logic ready for a distant future,
where one may allow the chat session to be switched even
if there is a pending ai server / tool call response.

Avoids the unneeded removeChild before calling appendChild.

Also found the reason why sometimes the DivStream was missing
from DivChat. Rather when I switched from the transient <p>
element to the persistant session specific <div> elements,
I had forgotten to convert the flow fully, rather I had
forgotten to replace the elP.remove() with elP.replaceChildren

Also retaining that debug log wrt missing DivStream path, Just
in case for now, to cross check once later, I havent missed
any other path.

Subject: [PATCH 343/446] SimpleChatTCRV:DivStreams: Enhanced Object using
 JSDoc++

Make DivStream hold a Role element and Data element and inturn
have the live got data go into the data element.

Set some of the relavent classes wrt these, so that it is themed
matching other chat blocks, to any extent.

Add a clear helper function to cleanup as and when needed.

NOTE: Remember to use this to get hold of the DivStream instance
being worked on.

NOTE: Dont forget that setting a parent wrt a HTMLElement wont
automatically add it to the corresponding DOM with a parent child
relation. The new html element will just remain in memory ignored
by everyone else.

Subject: [PATCH 345/446] SimpleChatTCRV:ToolCall:ExternalAi: Show its response
 live

Include the DivStream of ExternalAi toolcall in the other chat
session UIs, so that user can see what the external_ai toolcall
is doing, without having to switch out to external ai session tab.

Update the name of the tool call external ai session.

Ensure to clear previous chat session wrt external ai tool calls
As the ai may call external ai toolcall with the same system
prompt sometimes, which wont trigger the autoclear logic, wrt
the corresponding chat session.

TODO: In future maybe provide a option to continue any previous
chat session if the system prompt is not changed wrt external ai
toolcall.

Subject: [PATCH 346/446] SimpleChatTCRV:ToolCalls Cleanup

Update the external ai tool call description to indicate that it
doesnt have access to internet or tool calls.

Update the sys_date_time description and avoid the confusion caused
to some ai wrt the template string as to whether it is optional or
required and wasting reasoning time around it. Now simply state that
it is a reqd argument, and suggest the internal default template as
a useful one to use.

Update the msg returned by data store tool calls, to make them less
verbose (ie avoid duplicating key list or got key data) while also
more informative (ie num of keys, data length)

Update the readme.

Subject: [PATCH 347/446] SimpleChatTCRV:Config:WIP: Move config fields into a
 Config class

TODO: Rather than maintaining a reference to Me within SimpleChat,
maintain an duplicated instance of the Config class in there, bcas
that is what is needed in SimpleChat wrt Me.

This should also avoid the seperete data object which was created
yesterday to accomodate external_ai tool call.

Subject: [PATCH 348/446] SimpleChatTCRV:Config:WIP:Switch SimpleChat to Config
 from Me

Update SimpleChat to have a duplicated instance of Config instead
of a reference to the global Me instance.

Most logics updated to work with the config entries corresponding
to the current chat session.

ShowSettings, ShowInfo and getting current sliding window size in
user friendly textual form have been moved to Config from Me.

ALERT: With this now, user clicking settings will be able to modify
only the settings corresponding to current in focus chat session.

TODO:
ToolsMgr related use within SimpleChat and beyond needs to be thought
through and updated as needed.

Should tools.proxyUrl be unique to each SimpleChat or ...

Subject: [PATCH 349/446] SimpleChatTCRV:Config+:WIP:CleanUp: Have sensible
 chatIds

Given that now currently settings relates to only those related
to the current chat session, so indicate the name/chatId of the
current chat session in the Settings heading.

* this inturn makes the id dynamic, so change the css rule wrt
settings block from using id to classname, and to help with same
also set a class name for the top level settings block.

As part of same, as well as to help and ensure sanity in general
add a helper to clean up a string to be a form usable as a chatId

Subject: [PATCH 351/446] SimpleChatTCRV:Config:Tools: Adapt for SimpleChat
 with Config

Split init from setup wrt Tools. Init is called when the program
is started, while setup is called when ever a session is created
and or when ever any tools setup related config is changed (like
proxyUrl getting modified or so).

This allows one to modify tool related config and inturn update
the tools related states wrt same (like wrt the proxyUrl, bcas
the simpleproxy server will change, one needs to cross check which
and all web services are available with the new simpleproxy server
and so and so ...)

To help with the above, now ToolsManager maintains multiple tool
call switches, where there will be a tc_switch wrt each chat
session.

All tool related codes, where needed have been updated to work
with the chat session for which they have been called, instead
of any global states.

In future, this can enable one to allow user to enable or disable
the tool calls exposed in each of the chat sessions,

This immidiately needed toolweb and toolai to account for chat
session as needed.

In future, if we want to keep the data store isolated across
chat sessions, then this can be useful, in that it can create
uniq store names for each of the chat sessions, isntead of
sharing a common store name across all sessions.

The chat session creation as well as tool init/setup related
flows have been updated to chain through or account for the
promises as needed

Subject: [PATCH 352/446] SimpleChatTCRV:Config++: ValidatedToolCall UI updated

Given that ValidatedToolCallTrigger UI setup has to also setup
the auto trigger logic, which inturn is dependent on the autosecs
value in the Config associated with the Chat session involved, so
pass chatId to ShowMessage and inturn ValidatedToolCallTriggerUI
setup logic

Rename the function name to better match the semantic.

 Have a seperate helper to show the user input area, based on set state. And have support for multiple images

Subject: [PATCH 356/446] SimpleChatTCRV:AnveshikaSallap: cleanup in general

Rename the default 2 chat session names to make them neutral.

Update internal name to include AnveshikaSallap, better matching
the semantic of the logic, given support for tool calling, vision,
reasoning, ...

Also update usage note wrt simpleproxy.py for web access related
tool calls and few other minor tweeks.

Ensure we are working with the Chat Messages in Chat session, which
are in the currently active sliding window.

Remove any chat message blocks in the chat session ui, which are
no longer in the sliding window of context.

This brings uirefresh semantic to be in sync with chat_show logic

+# Progress
+
+Look into source files and git logs for the details, this is a partial changelog of stuff already done
+and some of the things that one may look at in the future.
+
+## Done
+
+Tool Calling support added, along with a bunch of useful tool calls as well as a bundled simple proxy
+if one wants to access web as part of tool call usage.
+
+Reasoning / thinking response from Ai Models is shown to the user, as they are being generated/shared.
+
+Chat Messages/Session and UI handling have been moved into corresponding Classes to an extent, this
+helps ensure that
+* switching chat sessions or loading a previous auto saved chat session will restore state including
+  ui such that end user can continue the chat session from where they left it, even if in the middle
+  of a tool call handshake.
+* new fields added to http handshake in oneshot or streaming mode can be handled in a structured way
+  to an extent.
+
+Chat message parts seperated out and tagged to allow theming chat message as needed in future.
+The default Chat UI theme/look changed to help differentiate between different messages in chat
+history as well as the parts of each message in a slightly better manner. Change the theme slightly
+between normal and print views (beyond previous infinite height) for better printed chat history.
+
+A builtin data store related tool calls, inturn built on browser's indexedDB, without needing any
+proxy / additional helper to handle the store. One could use the ai assistant to store ones (ie end
+users) own data or data of ai model.
+
+Trap http response errors and inform user the specific error returned by ai server.
+
+Initial go at a pdftext tool call. It allows web / local pdf files to be read and their text content
+extracted and passed to ai model for further processing, as decided by ai and end user. One could
+either work with the full pdf or a subset of adjacent pages.
+
+SimpleProxy updates
+* Convert from a single monolithic file into a collection of modules.
+* UrlValidator to cross check scheme and domain of requested urls,
+  the whitelist inturn picked from config json
+* Helpers to fetch file from local file system or the web, transparently
+* Help check for needed modules before a particular service path is acknowledged as available
+  through /aum service path
+* urltext and related - logic to drop contents of specified tag with a given id
+  * allow its use for the web search tool flow
+    * setup wrt default duckduckgo search result urltext plain text cleanup and found working.
+  * this works properly only if the html being processed has proper opening and ending tags
+    around the area of interest.
+  * remember to specify non overlapping tag blocks, if more than one specified for dropping.
+    * this path not tested, but should logically work
+
+Settings/Config default changes
+
+* Chances are for ai models which dont support tool calling, things will be such that the tool calls
+meta data shared will be silently ignored without much issue. So enabling tool calling feature by
+default, so that in case one is using a ai model with tool calling the feature is readily available
+for use.
+
+* Revert SlidingWindow ChatHistory in Context from last 10 to last 5 (rather 2 more then origianl,
+given more context support in todays models) by default, given that now tool handshakes go through
+the tools related side channel in the http handshake and arent morphed into normal user-assistant
+channel of the handshake.
+
+* Enable CachePrompt api option given that tool calling based interactions could involve chat sessions
+having ai responses built over multiple steps of tool callings etal. So independent of our client side
+sliding window based drop off or even before they kick in, this can help in many cases.
+
+UI - add ClearChat button and logic. Also add unicode icons for same as well as for Settings.
+
+Renamed pdf_to_text to fetch_pdf_as_text so that ai model can understand the semantic better.
+
+sys_date_time tool call has been added.
+
+Refactor code and flow a bit wrt the client web ui
+* Move the main chat related classes into its own js module file, independent of the main
+  runtime entry point (rather move out the runtime entry point into its own file). This allows
+  these classes to be referenced from other modules like tools related modules with full access
+  to these classes's details for developers and static check tools.
+* building on same make the Tools management code into a ToolsManager class which is inturn
+  instantiated and the handle stored in top level Me class. This class also maintains and
+  manages the web workers as well as routing of the tool calling among others.
+* add a common helper for posting results directly to the main thread side web worker callback
+  handlers. Inturn run the calling through a setTimeout0, so that delayed/missing response
+  situation rescuer timeout logic etal flow doesnt get messed for now.
+
+Track tool calling and inturn maintain pending tool calls so that only still valid tool call responses
+will be accepted when the asynchronous tool call response is recieved. Also take care of clearing
+pending tool call tracking in unhappy paths like when exception noticied as part of tool call execution,
+or if there is no response within the configured timeout period.
+NOTE: Currently the logic supports only 1 pending tool call per chat session.
+
+Add support for fetch_xml_as_text tool call, fix importmaps in index.html
+
+Renamed and updated logic wrt xml fetching to be fetch_xml_filtered. allow one to use re to identify
+the tags to be filtered in a fine grained manner including filtering based on tag heirarchy
+* avoid showing empty skipped tag blocks
+
+Logic which shows the generated tool call has been updated to trap errors when parsing the function call
+arguments generated by the ai. This ensures that the chat ui itself doesnt get stuck in it. Instead now
+the tool call response can inform the ai model that its function call had issues.
+
+Renamed fetch_web_url_text to fetch_html_text, so that gen ai model wont try to use this to fetch xml or
+rss files, because it will return empty content, because there wont be any html content to strip the tags
+and unwanted blocks before returning.
+
+Capture the body of ai server not ok responses, to help debug as well as to show same to user.
+
+Extract and include the outline of titles (along with calculated numbering) in the text output of pdftext
+* ensure that one doesnt recurse beyond a predefined limit.
+
+Convert NSChatMessage from typedef to Class and update ChatMessageEx, SimpleChat, MultiChatUI classes to
+make use of the same.
+* helpers consolidated
+  * helpers to check if given instance contains reasoning or content or toolcall or tool response related
+    fields/info in them.
+  * helpers to get the corresponding field values
+  * some of these helpers where in ChatMessageEx and beyond before
+* now the network handshaked fields are declared as undefined by default (instead of empty values).
+  this ensures that json stringify will automatically discard fields whose values are still undefined.
+* add fields wrt tool response and update full flow to directly work with these fields instead of the
+  xml based serialisation which was previously used for maintaining the different tool response fields
+  within the content field (and inturn extract from there when sending to server).
+  * now a dataset based attribute is used to identify when input element contains user input and when
+    it contains tool call result/response.
+* this simplifies the flow wrt showing chat message (also make it appear more cleanly) as well as
+  identifying not yet accepted tool result and showing in user query input field and related things.
+* ALERT: ON-DISK-STORAGE structure of chat sessions have changed wrt tool responses. So old saves will
+  no longer work wrt tool responses
+
+UI updates
+* update logic to allow empty tool results to be sent to ai engine server
+* css - when user input textarea is in tool result mode (ie wrt TOOL.TEMP role), change the background
+  color to match the tool role chat message block color, so that user can easily know that the input
+  area is being used for submitting tool response or user response, at any given moment in time.
+
+Vision
+* Add image_url field. Allow user to load image, which is inturn stored as a dataURL in image_url.
+* when user presses submit with a message, if there is some content (image for now) in dataURL,
+  then initialise image_url field with same.
+* when generating chat messages for ai server network handshake, create the mixed content type of
+  content field which includes both the text (from content field) and image (from image_url field)
+  ie if a image_url is found wrt a image.
+  * follow the openai format/template wrt these mixed content messages.
+* Usage: specify a mmproj file directly or through -hf, additionally had to set --batch-size to 8k
+  and ubatch-size to 2k wrt gemma3-4b-it
+* when showing chat instantiate img elements to show image_urls.
+  * limit horizontally to max width and vertically to 20% of the height
+* show any image loaded by the user, in the corresponding image button
+* consolidate dataurl handling into a bunch of helper functions.
+* trap quota errors wrt localStorage etal
+* dont forget to reset the file type input's value, so that reselecting the same image still
+  triggers the input's change event.
+
+SimpleChat class now allows extra fields to be specified while adding, in a generic way using a
+object/literal object or equivalent.
+
+UI Cleanup - msgs spaced out, toolcall edit hr not always, scroll ui only when required,
+hide settings/info till user requests, heading gradient
+
+iDB module
+* add open, transact, put and get. Use for chat session save and load
+* getKeys used to show Restore/Load button wrt chat sessions.
+
+ChatMessage
+* assign a globally unique (ie across sessions) id to each chat message instance.
+* add support for deleting chat message based on its uniquie id in SimpleChat.
+  * try ensure that adjacent messages remain on screen, after a message is deleted from session.
+* add a popover div block in html, which acts as a popup menu containing buttons to work with
+  individual chat messages.
+  * experiment and finalise on anchor based relative positioning of the popover menu.
+  * have a del button, which allows one to delete the currently in focus chat message.
+  * have a copy button, which allows one to copy the textual content into system clipboard.
+
+MultiChatUI
+* chat_show takes care of showing or clearing tool call edit / trigger as well as tool response
+  edit / submit. Also show the currently active tool call and its response before it is submitted
+  was previously only shown in the edit / trigger and edit / submit ui elements, now instead it
+  also shows as part of the chat session message blocks, so that user can delete or copy these
+  if needed using the same mechanism as other messages in the chat session.
+* use a delete msg helper, which takes care of deleting the msg from chat session as well as
+  efficiently update ui to any extent by removing the corresponding element directly from existing
+  chat session ui without recreating the full chat session ui.
+* a helper to add a message into specified chat session, as well as show/update in the chat session
+  ui by appending the chat message, instead of recreating the full chat session ui.
+...
+
+MultiChatUI+
+* both chat_show and chat_uirefresh (if lastN >= 2) both take care of updating tool call edit/trigger
+  as well as the tool call response edit/submit related ui elements suitably.
+  * chat_show recreates currently active sliding window of chat session (which could even be full)
+  * while chat_uirefresh recreates/updates ui only for the lastN messages (prefer in general, as optimal)
+* normal user response / query submit as well as tool call response or error submit have been updated
+  to use the optimal uirefresh logic now.
+
+Cleanup in general
+* Inform end user when loading from a saved session.
+* Update starting entry point flow to avoid calling chat_show twice indirectly, inturn leading to
+  two restore previously saved session blocks. Rather when adding tool calls support, and inturn
+  had to account for delayed collating of available simpleproxy based tool calls, I forgot to clean
+  this flow up.
+* Make the sys_date_time template description bit more verbose, just in case.
+* ui_userinput_reset now also resets associated Role always, inturn
+  * full on version from chat_show, inturn when session switching.
+    So user switchs session will reset all user input area and related data, while
+    also ensuring user input area has the right needed associated role setup.
+  * partial version from uirefresh, inturn adding user or tool call response messages.
+* ui cleanup
+  * more rounded buttons, chat messages and input area elements.
+  * make the body very very lightly gray in color, while the user input area is made whiter.
+  * gradients wrt heading, role-specific individual chat message blocks.
+  * avoid borders and instead give a box effect through light shadows.
+    * also avoid allround border around chat message role block and instead have to only one side.
+  * timeout close popover menu.
+  * usage notes
+    * update wrt vision and toggling of sessions and system prompt through main title area.
+    * fix issue with sliding window size not reflecting properly in context window entry.
+  * make restore block into details based block, and anchor its position independent of db check.
+  * avoid unneeded outer overall scrollbar by adjusting fullbody height in screen mode.
+  * user css variable to define the overall background color and inturn use same to merge gradients
+    to the background, as well as to help switch the same seemlessly between screen and print modes.
+  * make the scrollbars more subtle and in the background.
+  * allow user input textarea to grow vertically to some extent.
+  * make things rounded across board by default. add some padding to toolcall details block, ...
+  * use icons without text wrt chat sessions++, new chat, clear chat and settings top level buttons.
+    * use title property/attribute to give a hint to the user about the button functionality.
+  * add role specific background gradients wrt the tool call trigger and user input block as well as
+    fix wrt the tool temp message block. also wrt system input block at top.
+    * also rename the TEMP role tags to use -TEMP instead of .TEMP, so that CSS rule selectors will
+      treat such tags like role-TOOL-TEMP as say a proper css class name rather than messing up with
+      something like role-TOOL.TEMP which will get split to role-TOOL and TEMP and inturn corresponding
+      css rule doesnt/wont get applied.
+    * given that now there is a proper visual cue based seperation of the tool call trigger block from
+      surrounding content, using proper seperate tool call specific coloring, so remove the <HR> horiz
+      line seperation wrt tool call trigger block.
+    * however retain the horizontal line seperation between the tool trigger block and user input block,
+      given that some users and some ai dont seem to identify the difference very easily.
+  * work around firefox currently not yet supporting anchor based relative positioning of popover.
+  * ensure the new uirefresh flow handles the following situations in a clean way like
+    * a new chat session clearing out usagenote+restore+currentconfig, as user starts chatting
+    * the settings ui getting cleared out as user starts/continues chatting directly into user input
+      without using chat session button to switch back to the chat.
+* Auto ObjPropsEdit UI
+  * allow it to be themed by assigning id to top level block.
+  * fix a oversight (forgotten $) with use of templated literals and having variables in them.
+  * ensure full props hierarchy is accounted for when setting the id of elements.
+* Chat button to toggle sessions buttons and system prompt.
+* Use unix date format markers wrt sys_date_time toolcall, also add w (day of week).
+* Free up the useful vertical space by merging chat sessions buttons/tabs into heading
+* Allow user to load multiple images and submit to ai as part of a single user message.
+* Use popover ui to allow user to view larger versions of loaded images as well as remove before submitting
+  to ai, if and when needed.
+* Add external_ai toolcall with no access to internet or tool calls (helps avoid recursive ai tool calling).
+  User can see response generated by the external ai tool call, as and when it is recieved.
+* Maintain chat session specific DivStream elements, and show live ai responses (through corresponding
+  DivStream) wrt the current chat session as well as any from the external ai tool call session.
+  In future, if the logic is updated to allow switching chat session ui in the middle of a pending tool call
+  or pending ai server response, things wont mess up ui, as they will be updating their respective DivStream.
+  Also switching sessions takes care of showing the right DivStream ie of currently switched to chat, so that
+  end user can see the streamed response from that chat session as it is occuring.
+* Cleanup the tool call descriptions and verbose messages returned a bit.
+
+Chat Session specific settings
+* Needed so that one could
+  * setup a different ai model / engine as the external ai backend.
+  * interact with different independent ai models / engines / parallel instances in general
+* Move needed configs from Me into a seperate Config class.
+  * also move ShowSettings, ShowInfo etal into Config class
+* SimpleChat maintains an instance of Config class instead of Me.
+* ToolsManager and the different tool call modules have been updated to
+  * have seperate init and setup calls.
+    * init is called at the begining
+    * setup will be called when ever a chat session is being created
+      and or in future when ever any config of interest changes.
+  * pick needed config etal from the specified chatId's config and not any global config.
+* Starting flow updated to chain the different logical blocks of code
+  * first allow tools manager to be initd
+  * next create the needed default set of sessions, while parallely calling tool manager setup as needed.
+    * ensures that the available list of tool calls match the config of the chat session involved.
+      Needed as user could change tools related proxy server url.
+  * next setup the main ui as needed.
+* Hide user-input area and tool call validate/trigger area when switching into settings and ensure they
+  get unhidden when returning back, as needed.
+* Save and restore ChatSession config entries, as needed, in localStorage.
+  * load previously saved config if any, when creating ChatSession
+  * when ever switching, including into a, ChatSession, Configs of all chat sessions are saved.
+* ALERT: If a chat session's tools proxyUrl is changed
+  * the same will be picked up immidiately wrt all subsequent tool calls which depend on the
+    tool call proxy server.
+  * however any resultant changes to the available tool calls list wont get reflected,
+    till one reloads the program.
+* uirefresh helper ensures client side sliding window is always satisfied.
+  * now it remove messages no longer in the sliding window, so user only sees what is sent to the ai server,
+    in the chat session messages ui.
+  * avoids adding additional control specifically for ui, and instead stick to the ai nw handshake related
+    chat sliding window size (which takes care of try avoid overloading the ai model context size) selected
+    by user already. User can always change the sliding window size to view past messages beyond the currently
+    active sliding window size and then switch back again, if they want to.
+
+
+## ToDo
+
+Is the tool call promise land trap deep enough, need to think through and explore around this once later.
+
+Add fetch_rss and may be different document formats processing related tool calling, in turn through
+the simpleproxy.py if and where needed.
+
+* Using xmlfiltered and tagDropREs of
+  * ["^rss:channel:item:(?!title).+$"] one can fetch and extract out all the titles.
+  * ["^rss:channel:item:(?!title|link|description).+$"] one can fetch and extract out all the
+    titles along with corresponding links and descriptions
+  * rather with some minimal proding and guidance gpt-oss generated this to use xmlfiltered to read rss
+
+Add a option/button to reset the chat session config, to defaults.
+
+Have a seperate helper to show the user input area, based on set state. And have support for multiple images
+if the models support same. It should also take care of some aspects of the tool call response edit / submit,
+potentially.
+
+MAYBE add a special ClientSideOnly role for use wrt Chat history to maintain things to be shown in a chat
+session to the end user, but inturn not to be sent to the ai server. Ex current settings, any edits to toolcall,
+any tool call or server handshake errors seen (which user might have worked around as needed and continued the
+conversation) or so ...
+
+Updating system prompt, will reset user input area fully now, which seems a good enough behaviour, while

-### Progress
-
-#### Done
-
-Tool Calling support added, along with a bunch of useful tool calls as well as a bundled simple proxy
-if one wants to access web as part of tool call usage.
-
-Reasoning / thinking response from Ai Models is shown to the user, as they are being generated/shared.
-
-Chat Messages/Session and UI handling have been moved into corresponding Classes to an extent, this
-helps ensure that
-* switching chat sessions or loading a previous auto saved chat session will restore state including
-  ui such that end user can continue the chat session from where they left it, even if in the middle
-  of a tool call handshake.
-* new fields added to http handshake in oneshot or streaming mode can be handled in a structured way
-  to an extent.
-
-Chat message parts seperated out and tagged to allow theming chat message as needed in future.
-The default Chat UI theme/look changed to help differentiate between different messages in chat
-history as well as the parts of each message in a slightly better manner. Change the theme slightly
-between normal and print views (beyond previous infinite height) for better printed chat history.
-
-A builtin data store related tool calls, inturn built on browser's indexedDB, without needing any
-proxy / additional helper to handle the store. One could use the ai assistant to store ones (ie end
-users) own data or data of ai model.
-
-Trap http response errors and inform user the specific error returned by ai server.
-
-Initial go at a pdftext tool call. It allows web / local pdf files to be read and their text content
-extracted and passed to ai model for further processing, as decided by ai and end user. One could
-either work with the full pdf or a subset of adjacent pages.
-
-SimpleProxy updates
-* Convert from a single monolithic file into a collection of modules.
-* UrlValidator to cross check scheme and domain of requested urls,
-  the whitelist inturn picked from config json
-* Helpers to fetch file from local file system or the web, transparently
-* Help check for needed modules before a particular service path is acknowledged as available
-  through /aum service path
-* urltext and related - logic to drop contents of specified tag with a given id
-  * allow its use for the web search tool flow
-    * setup wrt default duckduckgo search result urltext plain text cleanup and found working.
-  * this works properly only if the html being processed has proper opening and ending tags
-    around the area of interest.
-  * remember to specify non overlapping tag blocks, if more than one specified for dropping.
-    * this path not tested, but should logically work
-
-Settings/Config default changes
-
-* Chances are for ai models which dont support tool calling, things will be such that the tool calls
-meta data shared will be silently ignored without much issue. So enabling tool calling feature by
-default, so that in case one is using a ai model with tool calling the feature is readily available
-for use.
-
-* Revert SlidingWindow ChatHistory in Context from last 10 to last 5 (rather 2 more then origianl,
-given more context support in todays models) by default, given that now tool handshakes go through
-the tools related side channel in the http handshake and arent morphed into normal user-assistant
-channel of the handshake.
-
-* Enable CachePrompt api option given that tool calling based interactions could involve chat sessions
-having ai responses built over multiple steps of tool callings etal. So independent of our client side
-sliding window based drop off or even before they kick in, this can help in many cases.
-
-UI - add ClearChat button and logic. Also add unicode icons for same as well as for Settings.
-
-Renamed pdf_to_text to fetch_pdf_as_text so that ai model can understand the semantic better.
-
-sys_date_time tool call has been added.
-
-Refactor code and flow a bit wrt the client web ui
-* Move the main chat related classes into its own js module file, independent of the main
-  runtime entry point (rather move out the runtime entry point into its own file). This allows
-  these classes to be referenced from other modules like tools related modules with full access
-  to these classes's details for developers and static check tools.
-* building on same make the Tools management code into a ToolsManager class which is inturn
-  instantiated and the handle stored in top level Me class. This class also maintains and
-  manages the web workers as well as routing of the tool calling among others.
-* add a common helper for posting results directly to the main thread side web worker callback
-  handlers. Inturn run the calling through a setTimeout0, so that delayed/missing response
-  situation rescuer timeout logic etal flow doesnt get messed for now.
-
-Track tool calling and inturn maintain pending tool calls so that only still valid tool call responses
-will be accepted when the asynchronous tool call response is recieved. Also take care of clearing
-pending tool call tracking in unhappy paths like when exception noticied as part of tool call execution,
-or if there is no response within the configured timeout period.
-NOTE: Currently the logic supports only 1 pending tool call per chat session.
-
-Add support for fetch_xml_as_text tool call, fix importmaps in index.html
-
-Renamed and updated logic wrt xml fetching to be fetch_xml_filtered. allow one to use re to identify
-the tags to be filtered in a fine grained manner including filtering based on tag heirarchy
-* avoid showing empty skipped tag blocks
-
-Logic which shows the generated tool call has been updated to trap errors when parsing the function call
-arguments generated by the ai. This ensures that the chat ui itself doesnt get stuck in it. Instead now
-the tool call response can inform the ai model that its function call had issues.
-
-Renamed fetch_web_url_text to fetch_html_text, so that gen ai model wont try to use this to fetch xml or
-rss files, because it will return empty content, because there wont be any html content to strip the tags
-and unwanted blocks before returning.
-
-Capture the body of ai server not ok responses, to help debug as well as to show same to user.
-
-Extract and include the outline of titles (along with calculated numbering) in the text output of pdftext
-* ensure that one doesnt recurse beyond a predefined limit.
-
-Convert NSChatMessage from typedef to Class and update ChatMessageEx, SimpleChat, MultiChatUI classes to
-make use of the same.
-* helpers consolidated
-  * helpers to check if given instance contains reasoning or content or toolcall or tool response related
-    fields/info in them.
-  * helpers to get the corresponding field values
-  * some of these helpers where in ChatMessageEx and beyond before
-* now the network handshaked fields are declared as undefined by default (instead of empty values).
-  this ensures that json stringify will automatically discard fields whose values are still undefined.
-* add fields wrt tool response and update full flow to directly work with these fields instead of the
-  xml based serialisation which was previously used for maintaining the different tool response fields
-  within the content field (and inturn extract from there when sending to server).
-  * now a dataset based attribute is used to identify when input element contains user input and when
-    it contains tool call result/response.
-* this simplifies the flow wrt showing chat message (also make it appear more cleanly) as well as
-  identifying not yet accepted tool result and showing in user query input field and related things.
-* ALERT: ON-DISK-STORAGE structure of chat sessions have changed wrt tool responses. So old saves will
-  no longer work wrt tool responses
-
-UI updates
-* update logic to allow empty tool results to be sent to ai engine server
-* css - when user input textarea is in tool result mode (ie wrt TOOL.TEMP role), change the background
-  color to match the tool role chat message block color, so that user can easily know that the input
-  area is being used for submitting tool response or user response, at any given moment in time.
-
-Vision
-* Add image_url field. Allow user to load image, which is inturn stored as a dataURL in image_url.
-* when user presses submit with a message, if there is some content (image for now) in dataURL,
-  then initialise image_url field with same.
-* when generating chat messages for ai server network handshake, create the mixed content type of
-  content field which includes both the text (from content field) and image (from image_url field)
-  ie if a image_url is found wrt a image.
-  * follow the openai format/template wrt these mixed content messages.
-* Usage: specify a mmproj file directly or through -hf, additionally had to set --batch-size to 8k
-  and ubatch-size to 2k wrt gemma3-4b-it
-* when showing chat instantiate img elements to show image_urls.
-  * limit horizontally to max width and vertically to 20% of the height
-* show any image loaded by the user, in the corresponding image button
-* consolidate dataurl handling into a bunch of helper functions.
-* trap quota errors wrt localStorage etal
-* dont forget to reset the file type input's value, so that reselecting the same image still
-  triggers the input's change event.
-
-SimpleChat class now allows extra fields to be specified while adding, in a generic way using a
-object/literal object or equivalent.
-
-UI Cleanup - msgs spaced out, toolcall edit hr not always, scroll ui only when required,
-hide settings/info till user requests, heading gradient
-
-iDB module
-* add open, transact, put and get. Use for chat session save and load
-* getKeys used to show Restore/Load button wrt chat sessions.
-
-ChatMessage
-* assign a globally unique (ie across sessions) id to each chat message instance.
-* add support for deleting chat message based on its uniquie id in SimpleChat.
-  * try ensure that adjacent messages remain on screen, after a message is deleted from session.
-* add a popover div block in html, which acts as a popup menu containing buttons to work with
-  individual chat messages.
-  * experiment and finalise on anchor based relative positioning of the popover menu.
-  * have a del button, which allows one to delete the currently in focus chat message.
-  * have a copy button, which allows one to copy the textual content into system clipboard.
-
-MultiChatUI
-* chat_show takes care of showing or clearing tool call edit / trigger as well as tool response
-  edit / submit. Also show the currently active tool call and its response before it is submitted
-  was previously only shown in the edit / trigger and edit / submit ui elements, now instead it
-  also shows as part of the chat session message blocks, so that user can delete or copy these
-  if needed using the same mechanism as other messages in the chat session.
-* use a delete msg helper, which takes care of deleting the msg from chat session as well as
-  efficiently update ui to any extent by removing the corresponding element directly from existing
-  chat session ui without recreating the full chat session ui.
-* a helper to add a message into specified chat session, as well as show/update in the chat session
-  ui by appending the chat message, instead of recreating the full chat session ui.
-...
-
-MultiChatUI+
-* both chat_show and chat_uirefresh (if lastN >= 2) both take care of updating tool call edit/trigger
-  as well as the tool call response edit/submit related ui elements suitably.
-  * chat_show recreates currently active sliding window of chat session (which could even be full)
-  * while chat_uirefresh recreates/updates ui only for the lastN messages (prefer in general, as optimal)
-* normal user response / query submit as well as tool call response or error submit have been updated
-  to use the optimal uirefresh logic now.
-
-Cleanup in general
-* Inform end user when loading from a saved session.
-* Update starting entry point flow to avoid calling chat_show twice indirectly, inturn leading to
-  two restore previously saved session blocks. Rather when adding tool calls support, and inturn
-  had to account for delayed collating of available simpleproxy based tool calls, I forgot to clean
-  this flow up.
-* Make the sys_date_time template description bit more verbose, just in case.
-* ui_userinput_reset now also resets associated Role always, inturn
-  * full on version from chat_show, inturn when session switching.
-    So user switchs session will reset all user input area and related data, while
-    also ensuring user input area has the right needed associated role setup.
-  * partial version from uirefresh, inturn adding user or tool call response messages.
-* ui cleanup
-  * more rounded buttons, chat messages and input area elements.
-  * make the body very very lightly gray in color, while the user input area is made whiter.
-  * gradients wrt heading, role-specific individual chat message blocks.
-  * avoid borders and instead give a box effect through light shadows.
-    * also avoid allround border around chat message role block and instead have to only one side.
-  * timeout close popover menu.
-  * usage notes
-    * update wrt vision and toggling of sessions and system prompt through main title area.
-    * fix issue with sliding window size not reflecting properly in context window entry.
-  * make restore block into details based block, and anchor its position independent of db check.
-  * avoid unneeded outer overall scrollbar by adjusting fullbody height in screen mode.
-  * user css variable to define the overall background color and inturn use same to merge gradients
-    to the background, as well as to help switch the same seemlessly between screen and print modes.
-  * make the scrollbars more subtle and in the background.
-  * allow user input textarea to grow vertically to some extent.
-  * make things rounded across board by default. add some padding to toolcall details block, ...
-  * use icons without text wrt chat sessions++, new chat, clear chat and settings top level buttons.
-    * use title property/attribute to give a hint to the user about the button functionality.
-  * add role specific background gradients wrt the tool call trigger and user input block as well as
-    fix wrt the tool temp message block. also wrt system input block at top.
-    * also rename the TEMP role tags to use -TEMP instead of .TEMP, so that CSS rule selectors will
-      treat such tags like role-TOOL-TEMP as say a proper css class name rather than messing up with
-      something like role-TOOL.TEMP which will get split to role-TOOL and TEMP and inturn corresponding
-      css rule doesnt/wont get applied.
-    * given that now there is a proper visual cue based seperation of the tool call trigger block from
-      surrounding content, using proper seperate tool call specific coloring, so remove the <HR> horiz
-      line seperation wrt tool call trigger block.
-    * however retain the horizontal line seperation between the tool trigger block and user input block,
-      given that some users and some ai dont seem to identify the difference very easily.
-  * work around firefox currently not yet supporting anchor based relative positioning of popover.
-  * ensure the new uirefresh flow handles the following situations in a clean way like
-    * a new chat session clearing out usagenote+restore+currentconfig, as user starts chatting
-    * the settings ui getting cleared out as user starts/continues chatting directly into user input
-      without using chat session button to switch back to the chat.
-* Auto ObjPropsEdit UI
-  * allow it to be themed by assigning id to top level block.
-  * fix a oversight (forgotten $) with use of templated literals and having variables in them.
-  * ensure full props hierarchy is accounted for when setting the id of elements.
-* Chat button to toggle sessions buttons and system prompt.
-* Use unix date format markers wrt sys_date_time toolcall, also add w (day of week).
-* Free up the useful vertical space by merging chat sessions buttons/tabs into heading
-* Allow user to load multiple images and submit to ai as part of a single user message.
-* Use popover ui to allow user to view larger versions of loaded images as well as remove before submitting
-  to ai, if and when needed.
-* Add external_ai toolcall with no access to internet or tool calls (helps avoid recursive ai tool calling).
-  User can see response generated by the external ai tool call, as and when it is recieved.
-* Maintain chat session specific DivStream elements, and show live ai responses (through corresponding
-  DivStream) wrt the current chat session as well as any from the external ai tool call session.
-  In future, if the logic is updated to allow switching chat session ui in the middle of a pending tool call
-  or pending ai server response, things wont mess up ui, as they will be updating their respective DivStream.
-  Also switching sessions takes care of showing the right DivStream ie of currently switched to chat, so that
-  end user can see the streamed response from that chat session as it is occuring.
-* Cleanup the tool call descriptions and verbose messages returned a bit.
-
-Chat Session specific settings
-* Needed so that one could
-  * setup a different ai model / engine as the external ai backend.
-  * interact with different independent ai models / engines / parallel instances in general
-* Move needed configs from Me into a seperate Config class.
-  * also move ShowSettings, ShowInfo etal into Config class
-* SimpleChat maintains an instance of Config class instead of Me.
-* ToolsManager and the different tool call modules have been updated to
-  * have seperate init and setup calls.
-    * init is called at the begining
-    * setup will be called when ever a chat session is being created
-      and or in future when ever any config of interest changes.
-  * pick needed config etal from the specified chatId's config and not any global config.
-* Starting flow updated to chain the different logical blocks of code
-  * first allow tools manager to be initd
-  * next create the needed default set of sessions, while parallely calling tool manager setup as needed.
-    * ensures that the available list of tool calls match the config of the chat session involved.
-      Needed as user could change tools related proxy server url.
-  * next setup the main ui as needed.
-* Hide user-input area and tool call validate/trigger area when switching into settings and ensure they
-  get unhidden when returning back, as needed.
-* Save and restore ChatSession config entries, as needed, in localStorage.
-  * load previously saved config if any, when creating ChatSession
-  * when ever switching, including into a, ChatSession, Configs of all chat sessions are saved.
-* ALERT: If a chat session's tools proxyUrl is changed
-  * the same will be picked up immidiately wrt all subsequent tool calls which depend on the
-    tool call proxy server.
-  * however any resultant changes to the available tool calls list wont get reflected,
-    till one reloads the program.
-* uirefresh helper ensures client side sliding window is always satisfied.
-  * now it remove messages no longer in the sliding window, so user only sees what is sent to the ai server,
-    in the chat session messages ui.
-  * avoids adding additional control specifically for ui, and instead stick to the ai nw handshake related
-    chat sliding window size (which takes care of try avoid overloading the ai model context size) selected
-    by user already. User can always change the sliding window size to view past messages beyond the currently
-    active sliding window size and then switch back again, if they want to.
-
-
-#### ToDo
-
-Is the tool call promise land trap deep enough, need to think through and explore around this once later.
-
-Add fetch_rss and may be different document formats processing related tool calling, in turn through
-the simpleproxy.py if and where needed.
-
-* Using xmlfiltered and tagDropREs of
-  * ["^rss:channel:item:(?!title).+$"] one can fetch and extract out all the titles.
-  * ["^rss:channel:item:(?!title|link|description).+$"] one can fetch and extract out all the
-    titles along with corresponding links and descriptions
-  * rather with some minimal proding and guidance gpt-oss generated this to use xmlfiltered to read rss
-
-Add a option/button to reset the chat session config, to defaults.
-
-Have a seperate helper to show the user input area, based on set state. And have support for multiple images
-if the models support same. It should also take care of some aspects of the tool call response edit / submit,
-potentially.
-
-MAYBE add a special ClientSideOnly role for use wrt Chat history to maintain things to be shown in a chat
-session to the end user, but inturn not to be sent to the ai server. Ex current settings, any edits to toolcall,
-any tool call or server handshake errors seen (which user might have worked around as needed and continued the
-conversation) or so ...
-
-Updating system prompt, will reset user input area fully now, which seems a good enough behaviour, while
-keeping the code flow also simple and straight, do I need to change it, I dont think so as of now.
-
-For now amn't bringing in mozilla/github/standard-entities pdf, md, mathslatex etal javascript libraries for
-their respective functionalities.
-
-Add support for base64 encoded pdf passing to ai models, when the models and llama engine gain that capability
-in turn using openai file - file-data type sub block within content array or so ...

+# SimpleChat / AnveshikaSallap
+
+by Humans for All.
+
+## Quickstart
+
+### Server
+
+From the root directory of llama.cpp source code repo containing build / tools / ... sub directories
+
+Start ai engine / server using
+
+```bash
+build/bin/llama-server -m <path/to/model.gguf> \
+  --path tools/server/public_simplechat --jinja
+```
+
+- `--jinja` enables tool‑calling support
+- `--mmproj <path/to/mmproj.gguf>` enables vision support
+- `--port <port number>` use if a custom port is needed
+
+If one needs web related access / tool calls dont forget to run
+
+```bash
+cd tools/server/public_simplechat/local.tools; python3 ./simpleproxy.py --config simpleproxy.json
+```
+
+- `--debug True` enables debug mode which captures internet handshake data.
+
+### Client
+
+1. Open `http://127.0.0.1:PORT/index.html` in a browser
+
+2. Select / Create a chat session
+   - set a suitable system prompt, if needed
+   - modify **settings**, if needed
+   - **Restore** loads last autosaved session with same name
+
+3. Enter the query, press **Enter**
+   - use **Shift‑Enter** for newline
+   - include images if required (ai vision models)
+
+4. View any streamed ai response (if enabled and supported)
+
+5. If a tool call is requested
+   - verify / edit the tool call details before triggering the same
+     - one can even ask ai to rethink on the tool call requested,
+       by sending a appropriate user response instead of a tool call response.
+   - tool call is executed using browser's web worker or simpleproxy
+   - tool call response is placed in user input area (with color coding)
+   - verify / edit the tool call response, before submit same back to ai
+     - tool response initially assigned `TOOL-TEMP` role, promoted to `TOOL` upon submit
+   - based on got response, if needed one can rerun tool call with modified arguments
+   - *at any time there can be one pending tool call wrt a chat session*
+
+6. **Delete / Copy** available via popover menu for each message
+
+7. **Clear** / **+ New** chat with provided buttons, as needed
+
+
+## Overview
+
+A lightweight ai chat client with a web front-end that supports multiple chat sessions, vision, reasoning and tool calling.
+
+- Supports multiple independent chat sessions with
+  - One‑shot or streamed (default) responses
+  - Custom settings and system prompts per session
+  - Automatic local autosave (restorable on next load)
+  - can handshake with `/completions` or `/chat/completions` (default) endpoints
+
+- Supports peeking at model's reasoning live
+  - if model streams the same and
+  - streaming mode is enabled in settings (default)
+
+- Supports vision / image / multimodal ai models
+  - attach image files as part of user chat messages
+    - handshaked as `image_url`s in chat message content array along with text
+    - supports multi-image uploads per message
+    - images displayed inline in the chat history
+  - specify `mmproj` file via `-mmproj` or using `-hf`
+  - specify `-batch-size` and `-ubatch-size` if needed
+
+- Built-in support for GenAI models that expose tool calling
+
+  - includes a bunch of useful builtin tool calls, without needing any additional setup
+
+  - direct browser based tool calls include
+    - `sys_date_time`, `simple_calculator`, `run_javascript_function_code`, `data_store_*`, `external_ai`
+    - except for external_ai, these are run from within a web worker context to isolate main context from them
+    - data_store brings in browser IndexedDB based persistant key/value storage across sessions
+
+  - along with included python based simpleproxy.py
+    - `search_web_text`, `fetch_web_url_raw`, `fetch_html_text`, `fetch_pdf_as_text`, `fetch_xml_filtered`
+      - these built‑in tool calls (via SimpleProxy) help fetch PDFs, HTML, XML or perform web search
+      - PDF tool also returns an outline with numbering
+      - result is truncated to `iResultMaxDataLength` (default 128 kB)
+    - helps isolate these functionality into a separate vm running locally or otherwise, if needed
+    - supports whitelisting of `allowed.schemes` and `allowed.domains` through `simpleproxy.json`
+    - supports a bearer token shared between server and client for auth
+      - needs https support, for better security wrt this flow, avoided now given mostly local use
+
+  - follows a safety first design and lets the user
+    - verify and optionally edit the tool call requests, before executing the same
+    - verify and optionally edit the tool call response, before submitting the same
+    - user can update the settings for auto executing these actions, if needed
+
+  - external_ai allows invoking a separate fresh ai instance
+    - ai could run self modified targeted versions of itself/... with custom system prompts and user messages as needed
+    - user can bring in an ai instance with additional compute access, which should be used only if needed
+    - tool calling is currently kept disabled in such a instance
+
+- Client side Sliding window Context control, using `iRecentUserMsgCnt`, helps limit context sent to ai model
+
+- Optional auto trimming of trailing garbage from model outputs
+
+- Follows responsive design to try adapt to any screen size
+
+- built using plain html + css + javascript and python
+  - no additional dependencies that one needs to keep track of
+    - except for pypdf, if pdf support needed. automaticaly drops pdf tool call if pypdf missing
+  - fits within ~260KB even in uncompressed source form (including simpleproxy.py)
+  - easily extend with additional tool calls using either javascript or python, for additional functionality
+
+Start exploring / experimenting with your favorite ai models and thier capabilities.
+
+
+## Configuration / Settings
+
+One can modify the session configuration using Settings UI. All the settings and more are also exposed in the browser console via `document['gMe']`.

+- **Stream** (`stream`)
+  - `true` for live streaming, `false` for oneshot
+- **Client side Sliding Window** (`iRecentUserMsgCnt`)
+  - `-1` : send full history
+  - `0`  : only system prompt
+  - `>0` : last N user messages after the most recent system prompt
+- **Cache Prompt** (`cache_prompt`)
+  - enables server‑side caching of system prompt and history
+- **Tool Call Timeout** (`toolCallResponseTimeoutMS`)
+  - 200s by default
+- **Tool call Auto** (`autoSecs`)
+  - seconds to wait before auto-triggering tool calls and auto-submitting tool responses

+
+## Debugging Tips
+
+- **Local TCPdump**
+  - `sudo tcpdump -i lo -s 0 -vvv -A host 127.0.0.1 and port 8080`
+- **Browser DevTools**
+  - inspect `document['gMe']` for session state
+- **Reset Tool Call**
+  - delete any assistant response after the tool call handshake
+  - next wrt the last tool message
+    - set role back to `TOOL-TEMP`
+      - edit the response as needed
+    - delete the same
+      - user will be given option to edit and retrigger the tool call
+    - submit the new response
+
+
+## At the end
+
+A thank you to all open source and open model developers, who strive for the common good.

Subject: [PATCH 365/446] SimpleChatTCRV:AiCallingAi ToolCall: flow cleanup and
 flexibility

By default ensure external_ai tool call related special chat session
starts with tool calls disabled and client side sliding window of 1.

Add a helper in SimpleChat class to set these along with clearing of
any chat history.

Inturn now give the user flexibility to change this from within
the program, if they need to for what ever reason, till the program
restarts.

 initial go

Ensure '---' is treated as a horizontal line and doesnt mess with
unordered list handling.

Take care of unwinding the unordered list everywhere it is needed.

Rather this wont work, need to refresh on regex, been too long.

Rather using split should be simpler

However the extraction of head and body parts with seperation
inbetween for transition should work

Rather the seperation is blindly assumed and corresponding line
discarded for now

Subject: [PATCH 378/446] SimpleChatTCRV:MarkDown:Table cleanup initial go

Switch to the simpler split based flow.

Include tr wrt the table head block also.

Add a css entry to try and have header cell contents text aling
to left for now, given that there is no border or color shaded
or so distinguishing characteristics wrt the table cells for now.

Subject: [PATCH 380/446] SimpleChatTCRV:MarkDown:Cleanup overall initial go

Save copy of data being processed.

Try and sanitize the data passed for markdown to html conversion,
so that if there are any special characters wrt html in the passed
markdown content, it gets translated into a harmless text.

This also ensures that those text dont disappear, bcas of browser
trying to interpret them as html tagged content.

Trap any errors during sanitizing and or processing of the lines
in general and push them into a errors array. Callers of this
markdown class can decide whether to use the converted html or
not based on errors being empty or not or ...

Move the processing of unordered list into a function of its own.
Rather the ordered list can also use the same flow in general except
for some tiny changes including wrt the regex, potentially.

Subject: [PATCH 384/446] SimpleChatTCRV:Markdown:OrderedUnOrderd: Simplify
 flow

Avoid seperate new list level logic for a fresh list and list with
in list paths. Rather adjust lastOffset specifically for fresh list.

All paths lead to need to insert list item and the difference to be
handled wrt starting or ending a list level is handled by respective
condition check blocks directly without delaying it for later so no
need for that sList state, so remove.

Avoid check for same level list item path, as nothing special needs
to be do in that path currently.

Live identify the last offset, when unwinding.

NOTE: Logic currently will handle ordered lists on their own or
unordered lists on thier own or intermixed list containing both
type of lists within them, however remember that all will be shown
as unordered lists.

ALERT: if there is a really long line, the logic currently doesnt
support it being broken into smaller line with same or greater
offset than the line identifying the current list item.

Subject: [PATCH 387/446] SimpleChatTCRV:Markdown:Lists - handle split lines to
 an extent

If a split line is found which remains within the constraints of
the preceding list item, then dont unwind the list, rather for
now add the split line as a new item at the same level.

If the split lines dont have any empty lines inbetween and also
remain within the block area of the list item which they belong
to, then the split line will be appended to the corresponding
list item, ELSE a new list item will be created.

To help with same a generic keyed empty lines tracker logic has
been added.

Similar to listitem before, now also allow a para to have its long
lines split into adjacent lines. Inturn the logic will take care of
merging them into single para.

The common logic wrt both flows moved into its own helper function.

Subject: [PATCH 394/446] SimpleChatTCRV:Markdown:ReEnable Sanitize, lineRaw

Maintain raw and sanitized versions of line.

Make blockquote work with raw line and not the sanitized line.
So irrespective of whether sanitize is enabled or not, the logic
will still work. Inturn re-enable HtmlSanitize.

Subject: [PATCH 396/446] SimpleChatTCRV:TC:FetchUrlRaw: Rename to avoid
 confusion

Given that now fetch_web_url_raw can also fetch local files, if local
file access scheme is enabled in simpleproxy.py, so rename this
tool call by dropping web from its name, given that some ai models
were getting confused because of the same.

Add format selection box to the popover.

Update show_message logic to allow refreshing a existing message
ui element, rather than creating a new one.

Trigger refresh of the message ui element, when format selection
changes.

Subject: [PATCH 403/446] SimpleChatTCRV:CMTextFormat: Common flow accounting
 User and Auto

If user explicitly makes a content text format selection, the
same will be used.

Else based on session settings, a format will be used.

Now when the popover menu is shown, the current message's format
type is reflected in the popover menu.

Subject: [PATCH 404/446] SimpleChatTCRV:UICleanup: Show own divstream mostly,
 ShowInfo all

Always show all the info wihen show_info is called, inturn avoid
the corresponding all info enable flag wrt show_info as well as
chat_show.

Now chat_show gives the option to its caller to enable showing of
its own chat session divStream. This is in addition to the handle
multipart response also calling corresponding divStream show.

Previously chat_show would have not only cleared corresponding chat
session's divStream contents but would have also hidden divStream.

Now except for the clearChat case, in all other cases own divStream
is unhidden, when chat_show is called.

Without this, when a tool call takes too much time and inturn
a chat session times out the tool call and inturn user switches
between chat sessions, if the tool call was external_ai, then its
related live ai response would no longer be visible in any of the
chat sessions, including the external_ai special chat session, if
the user had switched to this external_ai special chat session.
But now in the external_ai special chat session, the live response
will be visible.

TODO: With this new semantic wrt chat_show, where a end user can
always peek into a chat session's ai live stream response if any,
as long as that chat session's ai server handshake is still active,
So now After tool call timeout, which allows users to switch between
sessions, it is better to disable the external ai live divStream
in other chat sessions, when user switches into them. This ensures
that

1. if user doesnt switch out of the chat session which triggered
external_ai, for now the user can continue to see the ext ai live
response stream.

2. Switching out of the chat session which triggered ext ai, will
automatically disable viewing of external ai live response from
all chat sessions except for the external ai's special chat session.

IE I need to explicitly clear not just the own divStream, but also
the external ai related divStream, which is appened to end of all
chat session's UI.

This will tidy up the usage flow and ui and avoid forcefully showing
external ai tool call's ai live response in other chat sessions,
which didnt trigger the ext ai tool call. And also in the chat
session which triggered ext ai, it will stop showing if user exits
out of that chat session. Same time user can always look at the
ext ai live response stream in the special chat session corresponding
to ext ai.

Subject: [PATCH 405/446] SimpleChatTCRV:UICleanup:Ai Reasoning/Live response

Implement todo noted in last commit, and bit more.

This brings in clearing of the external ai tool call special chat
session divStream during chat show, which ensures that it gets
hidden by default wrt other chat sessions and inturn only get
enabled if user triggers a new tool call involving external ai
tool call.

This patch also ensures that if ext ai tool call takes too much
time and so logic gives you back control with a timed out response
as a possible response back to ai wrt the tool call, then the
external ai tool call's ai live response is no longer visible in
the current chat session ui. So user can go ahead with the timed
out response or some other user decided response as the response
to the tool call. And take the chat in a different direction of
their and ai's choosing.

Or else, if they want to they can switch to the External Ai
specific special chat session and continue to monitor the response
from the tool call there, to understand what the final response
would have been wrt that tool call.

Rather this should keep the ui flow clean.

ALERT: If the user triggers a new ext ai tool call, when the
old one is still alive in the background, then response from
both will be in a race for user visibility, so beware of it.

Subject: [PATCH 408/446] SimpleSallap:SimpleProxy: MultiThreading

Given that default HTTPServer handles only one connection and inturn
request at any given time, so if a client opens connection and then
doesnt do anything with it, it will block other clients by putting their
requests into network queue for long.

So to overcome the above issue switch to ThreadingHTTPServer, which
starts a new thread for each request.

Given that previously ssl wrapping was done wrt the main server socket,
even with switching to ThreadingHTTPServer, the handshake for ssl/tls
still occurs in the main thread before a child thread is started for
parallel request handling, thus the ssl handshake phase blocking other
client requests.

So now avoid wrapping ssl wrt the main server socket, instead wait for
ThreadingHttpServer to start the new thread for a client request ie
after a connection is accepted for the client, before trying to wrap
the connection in ssl. This ensures that the ssl handshake occurs in
this child (ie client request related) thread. So some rogue entity
opening a http connection and not doing ssl handshake wont block.

Inturn in this case the rfile and wfile instances within the proxy
handler need to be remapped to the new ssl wrapped socket.

identified as gMe as a generic literal dictionary which grows at
runtime with fields as required, try create it as a class of classes.

Inturn use dataclass annotation to let biolerplate code get auto

Subject: [PATCH 412/446] SimpleSallap:SimpleProxy:DataClass Config - P3

Add a helper base class to try map data class's attributes into
underlying dict.

TODO: this potentially duplicates data in both normal attribute
space as well as dict items space. And will require additional
standard helper logics to be overridden to ensure sync between
both space etal. Rather given distance from python internals for
a long time now, on pausing and thinking a bit, better to move
into a simpler arch where attributes are directly worked on for
dict [] style access.

Minimal skeleton to allow dict [] style access to dataclass based
class's attributes/fields. Also get member function similar to dict.

This simplifies the flow and avoids duplicating data between
attribute and dict data related name and data spaces.

Subject: [PATCH 415/446] SimpleSallap:SimpleProxy:use RequestHandler's setup
 after ssl hs

Instead of manually setting up rfile and wfile after switching to
ssl mode wrt a client request, now use the builtin setup provided
by the RequestHandler logic, so that these and any other needed
things will be setup as needed after the ssl hs based new socket,
just in case new things are needed in future.

Also remember to picks the tagDropREs from passed args object and
not from got http header.

Even TCHtmlText updated to get the tags to drop from passed args
object and not got http header. And inturn allow ai to pass this
optional arg, as it sees fit in co-ordination with user.

Define a typealias for HttpHeaders and use it where ever needed.
Inturn map this to email.message.Message and dict for now.
If and when python evolves Http Headers type into better one,
need to replace in only one place.

Add a ToolManager class which
* maintains the list of tool calls and inturn allows any given
  tool call to be executed and response returned along with needed
  meta data
* generate the overall tool calls meta data
* add ToolCallResponseEx which maintains full TCOutResponse for
  use by tc_handle callers

Avoid duplicating handling of some of the basic needed http header
entries.

Move checking for any dependencies before enabling a tool call into
respective tc??? module.
* for now this also demotes the logic from the previous fine grained
  per tool call based dependency check to a more global dep check at
  the respective module level

Subject: [PATCH 428/446] SimpleSallap:SimpleMCP: Use ToolManager for some of
 needed logics

Build the list of tool calls

Trap some of the MCP post json based requests and map to related
handlers. Inturn implement the tool call execution handler.

Add some helper dataclasses wrt expected MCP response structure

TOTHINK: For now maintain id has a string and not int, with idea
to map it directly to callid wrt tool call handshake by ai model.

TOCHECK: For now suffle the order of fields wrt jsonrpc and type
wrt MCP response related structures, assuming the order shouldnt
matter. Need to cross check.

Subject: [PATCH 429/446] SimpleSallap:SimpleMCP:tools/list

Fix a oversight wrt ToolManager.meta, where I had created a dict
of name-keyed toolcall metas, instead of a simple list of toolcall
metas. Rather I blindly duplicated structure I used for storing the
tool calls in the tc_switch in the anveshika sallap client side
code.

Add dataclasses to mimic the MCP tools/list response. However wrt
the 2 odd differences between the MCP structure and OpenAi tools
handshake structure, for now I have retained the OpenAi tools hs
structure.

Add a common helper send_mcp to ProxyHandler given that both
mcp_toolscall and mcp_toolslist and even others like mcp_initialise
in future require a common response mechanism.

With above and bit more implement initial go at tools/list response.

Subject: [PATCH 430/446] SimpleSallap:SimpleMCP:Body Bytes to Json within
 mcp_run

Given that there could be other service paths beyond /mcp exposed
in future, and given that it is not necessary that their post body
contain json data, so move conversion to json to within mcp_run
handler.

While retaining reading of the body in the generic do_POST ensures
that the read size limit is implicitly enforced, whether /mcp now or
any other path in future.

By default bearer based auth check is done always whether in https

to false, the bearer auth check will be carried out only in https
mode.

As expected dataclass field member mutable default values needing

Subject: [PATCH 443/446] SimpleSallap:SimpleMCP: Cleanup, Readme updates

Update the documentation a bit wrt switch from simpleproxy to
simplemcp with mcp-ish kind of handshake between the chat client
and simplemcp.

Rename proxyUrl and related to mcpServerUrl and mcpServerAuth.
Now include the path in the url itself, given that in future,
we may want to allow the chat client logic to handshake with
other mcp servers, which may expose their services through a
different path or so.

Drop SearchEngine related config entries from chat session
settings, given that its now controlled directly in SimpleMCP.
