My custom cccmd

Hi,

I love the new option to run a cccmd and how good it works on the linux kernel, but I couldn't find a generic script. So I decided to write my own.

It's very simple, it just looks into the authors of the commits that modified the lines being overridden (git blame). It's not checking for s-o-b, or anything fancy.

Comments?

#!/usr/bin/env ruby

@commits = {} # keeps a count of commits per author

ARGV.each do |filename|
  File.open(filename) do |patch_file|
    patch_file.each_line do |patch_line|
      case patch_line
      when /^---\s+(\S+)/
        @source = $1[2..-1]
      when /^@@\s-(\d+),(\d+)/
        blame = `git blame -p -L #{$1},+#{$2} #{@source} | grep author`
        blame.each_line do |al|
          key, value = al.chomp.split(" ", 2)
          case key
          when "author"
            @name = value
          when "author-mail"
            @mail = value
            author = "\"#{@name}\" #{@mail}"
            @commits[author] ||= 0
            @commits[author] += 1
          end
        end
      end
    end
  end
end

@commits.each_key do |a|
  puts a
end
