# intialize a new worktree from a PR number:
|
|

|
|
# - creates a new remote using the fork's clone URL
|
|
# - creates a local branch tracking the remote branch
|

# - creates a new worktree in a parent folder, suffixed with "-pr-$PR"

|
|
# ./scripts/pr2wt.sh 12345

# ./scripts/pr2wt.sh 12345 opencode

# ./scripts/pr2wt.sh 12345 "cmake -B build && cmake --build build"

# ./scripts/pr2wt.sh 12345 "bash -l"
