gitdiff.lua - an oddly specific git diff parser

gitdiff.lua is a gitdiff parser, so if you want to parse git diffs in lua for any other reason, feel free to use it under the MIT license

usage

place gitdiff.lua in the same folder as the script you'll be using it with

local gitdiff = require "gitdiff"

 -- diff is the output of the `git diff` command
 -- this only works on single-file diffs
gitdiff.changed_lines(diff)
-- returns a table that looks like the following:
{
	nil,
	nil,
	"addition",
	"addition",
	nil,
	nil,
	"modification",
	"deletion",
	nil,
	nil
}
-- where the index of the table is the line number the change corresponds to

test.lua

pipe a git diff into its stdin and it will run some tests on gitdiff.lua

eg: cat test_diff.txt | lua test.lua

eg #2: git diff gitdiff.lua | lua test.lua
