« Formatted code without the PRE | Main | Code Formatting in Blogs - Conclusions »

Same post but with embedded styles.

I'm trying to get a decent solution to inserting code in blog articles so the next few posts are all about the code. The sample below is a simple line counter tool I use to work out some metrics for code reviews.

using System; 
using System.Collections.Generic;
using System.Text;
using System.IO;

namespace LineCount
{
  class Program
  {
    private static int folders;
    private static int files;
    private static int lines;
    private static int code;
    private static int comments;

    static void Main(string[] args)
    {
      if (args.Length == 0)
      {
        Console.WriteLine(@"
Usage: linecount <root folder>

e.g. linecount t:\dev\projects\main

NB: Only .cs files are considered
  Review time is hard coded to 200 lines per hour
");
        return;
      }

      CountLines(new DirectoryInfo(args[0]));

      Console.WriteLine("FOLDERS:{0} FILES:{1} LOC:{2} SLOC:{3} COMMENTS:{4}", 
        folders, files, lines, code, comments);
      Console.WriteLine("Code density: {0:p}", 
        (double)code / (double)lines);
      Console.WriteLine("Comment density: {0:p}", 
        (double)comments / (double)lines);
      Console.WriteLine("Comment ratio: {0:p}", 
        (double)comments / (double)code);
      Console.WriteLine("Estimated review time: {0}h", 1+ (code / 200));
    }

    private static void CountLines(DirectoryInfo parent)
    {
      ++folders;

      foreach (DirectoryInfo folder in parent.GetDirectories())
      {
        CountLines(folder);
      }

      foreach (FileInfo file in parent.GetFiles())
      {
        CountLines(file);
      }
    }

    private static void CountLines(FileInfo file)
    {
      switch (file.Extension)
      {
        case ".cs":
          break;
        default:
          return;
      }

      ++files;

      using (StreamReader reader = file.OpenText())
      {
        string line = null;
        bool inComment = false;

        while ((line = reader.ReadLine()) != null)
        {
          ++lines;
          line = line.Trim();

          if (line.Length == 0)
            continue;

          if (line.StartsWith("//"))
          {
            if (line.Replace("//", "").Trim().Length > 0)
              ++comments;

            continue;
          }

          if (line.StartsWith("/*"))
            ++comments;
          else if (!inComment)
            ++code;

          if (line.Contains("/*"))
          {
            inComment = true;
          }

          if (inComment && line.Contains("*/"))
          {
            inComment = false;
          }
        }
      }
    }
  }
}
