Web App Autopsy<\/a> has some juicy metrics such as the 100:10:1 ratio of anonymous visitors to free registered users to paying users. But they also have LOC counts which seem quite high, and which include things that rake:stats (a Rake<\/a> task that’s part of Rails, which counts lines of source code and provides some basic analysis) doesn’t count. So, I hacked rake:stats to include them. Here’s what I did:
\n
\nI added this code to my Rakefile:<\/p>\n

\r\nnamespace :spec do\r\n  desc \"Add files that DHH doesn't consider to be 'code' to stats\"\r\n  task :statsetup do\r\n  require 'code_statistics'\r\n\r\n  class CodeStatistics\r\n    alias calculate_statistics_orig calculate_statistics\r\n    def calculate_statistics\r\n      @pairs.inject({}) do |stats, pair|\r\n        if 3 == pair.size\r\n          stats[pair.first] = calculate_directory_statistics(pair[1], pair[2]); stats\r\n        else\r\n          stats[pair.first] = calculate_directory_statistics(pair.last); stats\r\n        end\r\n      end\r\n    end\r\n  end\r\n  ::STATS_DIRECTORIES << ['Views',  'app\/views', \/\\.(rhtml|erb|rb)$\/]\r\n  ::STATS_DIRECTORIES << ['Test Fixtures',  'test\/fixtures', \/\\.yml$\/]\r\n  ::STATS_DIRECTORIES << ['Email Fixtures',  'test\/fixtures', \/\\.txt$\/]\r\n  # note, I renamed all my rails-generated email fixtures to add .txt\r\n  ::STATS_DIRECTORIES << ['Static HTML', 'public', \/\\.html$\/]\r\n  ::STATS_DIRECTORIES << ['Static CSS',  'public', \/\\.css$\/]\r\n  # ::STATS_DIRECTORIES << ['Static JS',  'public', \/\\.js$\/]\r\n  # prototype is ~5384 LOC all by itself - very hard to filter out\r\n\r\n  ::CodeStatistics::TEST_TYPES << \"Test Fixtures\"\r\n  ::CodeStatistics::TEST_TYPES << \"Email Fixtures\"\r\n  end\r\nend\r\ntask :stats => \"spec:statsetup\"\r\n<\/pre>\n
(This code is based on this code I found that does something related<\/a>.)<\/p>\n
As you can see it doesn’t count JavaScript because the included Prototype code that’s included by default in Rails projects is huge-mungous. You can just uncomment that and see your project grow by 5KLOC if you want. Or you can temporarily delete those files, maybe in a quick ‘svn export’ temporary directory, and run rake:stats in there to see what your own JavaScript stuff contributes.<\/p>\n
(I tried to get a fancy regex going that excluded the six files that make up Prototype, but I couldn’t get it to work quickly. I don’t care enough about that one issue to keep spending time on it, but if you figure out a clean way to get that done I’d love to see it, just post a comment.)<\/p>\n
Hope this proves useful!<\/p>\n","protected":false},"excerpt":{"rendered":"
