How it works

Match email addresses case-insensitively; a matching commit-name entry takes precedence over a general email entry.

The example maps A <OLD@example.com> to Alice Example <alice@example.com>.

Limits

Documented one-/two-address forms only. Repeated entries update supplied fields. This previews text mappings; it does not edit commits, repository files or the user’s Git configuration.

Git porcelain status parser

Decode status columns, renames and quoted UTF-8 paths from porcelain v1.

Utility

Git fetch refspec mapper

Preview positive and negative fetch mappings for supplied remote ref names.

Utility

Unified diff hunk counts
