Expand description

Parse a unified diff (git-style) and return scoped lines in diff order.

scope controls whether we return:

  • Scope::Added: all added lines
  • Scope::Changed: only added lines that directly follow at least one removed line in the same hunk
  • Scope::Modified: alias of Scope::Changed
  • Scope::Deleted: removed lines

Special cases handled:

  • Binary files: skipped (no lines extracted)
  • Submodule changes: skipped (no lines extracted)
  • Deleted files: skipped unless scope = deleted
  • Mode-only changes: skipped (no lines extracted)
  • Renamed files: uses the new (destination) path
  • Malformed content: continues processing subsequent files
