Hacky syntax highlighting in
git diff would color additions green and deletions red. This is cool, but it would be even cooler if it adds syntax highlighting to those lines. This is a git pager that does so.
It parses the diff output and picks up the SHAs of files with additions and deletions. It uses [CodeRay][coderay] to highlight each file and then it extracts the lines that are shown in the diff. It then uses [term/ansicolor][color] to make a gradient from the CodeRay color and the diff color (red for deletion, green for addition) and uses it to replace the original.
I tried using
rugged instead of shelling out to
git show – it was faster overall, but it did incur a noticeable start up time.
