git diff image files on the command line, with color

This is a simple way to spot check that the modified image in your git index is the image you actually want without having to leave the command line.

Instructions

  1. Install git, ImageMagick, and jp2a via your favorite package manager.
  2. Put img-ascii-diff somewhere (e.g. ~/bin/img-ascii-diff).
  3. Put attributes in ~/.config/git/attributes.
  4. Modify ~/.gitconfig and add the lines below, pointing to wherever you put img-ascii-diff.
