Getting Started

Use it with grunt

Install this grunt plugin next to your project's grunt.js gruntfile with: npm install grunt-git-diff

Then add this line to your project's grunt.js gruntfile:

grunt.loadNpmTasks('grunt-git-diff');

Documentation

Here the available options with the corresponding defaults:

# Regex which is used to get the hunk
# Note, that the index 2 is the number of overwritten lines
# index 3 is the linenumber where to overwrite, and index 5 is the current 
# environment, important for jade parsing
hunkregex: /@@ \-(\d+),(\d+) \+(\d+),(\d+) @@([\s\S]*)/

# string which is prepended if a line is added
prependplus: "span(style='color:red') "

# string which is prepended if a line is deleted
prependminus: "span(style='color:red') " 

# function which is used to calculate the new strings based on the hunk
# corresponding prepend / append strings
cb = (hunk, environment, options) ->
  # default is to parse jade

Example with jade

First append this to your css:

span.strongred, span.strongred * {color:red !important;}
span.strongblue, span.strongblue * {color:blue !important;}

This is how the task could look like, which creates a jade diff:

gitdiff:
  options:
    prependplus: "span.strongred " 
    prependminus:"span.strongblue "
  compile:
    files: [
      expand: true,
      cwd: "jade/",
      src: ["**/*.jade"],
      ext: ".jade",
      dest: "tmp/"   
    ]
