Documentation

Overview

Package gitdiff ports bat's diff module: it computes per-line modifications (added / removed / modified) between a file's working-tree state and the git index, so the printer can draw change markers in the gutter. It shells out to the git CLI with -U0 and parses the resulting hunk headers, mirroring the classification libgit2 performs in upstream bat.
