Module git 

Language-agnostic git utilities.

Provides shared git operations used across all language crates:

• File reading from git refs (read_git_file)
• File diffing between refs (git_diff_file)
• Ref name sanitization (sanitize_ref_name)
• Worktree path computation (worktree_path_for)
• RAII worktree management (WorktreeGuard)

These utilities were consolidated from duplicate implementations in crates/ts/ and crates/java/. Language crates should use these directly (or compose with WorktreeGuard) rather than reimplementing git plumbing.

Structs

DeprecationCommit

A commit that added files to a deprecated component directory.

WorktreeGuard

RAII guard for a temporary git worktree.

Functions

commit_co_changed_families

Find component families whose source files were modified in the given commit.

find_deprecation_commits

Find commits between from_ref and to_ref that added files to deprecated/components/ directories (i.e., commits that deprecated a component).

git_diff_file

Get the diff of a single file between two refs via git diff <from>..<to> -- <path>.

read_git_file

Read a file from a git ref via git show <ref>:<path>.

sanitize_ref_name

Sanitize a git ref name for use as a directory name.

worktree_dir_for

Return the parent directory for all worktrees of a given repo.

worktree_path_for

Generate a deterministic worktree path for a given ref.
