loc_counter

loc_counter is a command-line tool for measuring LOC (line-of-code) count in your Ruby project or some set of arbitrary Ruby source files.

gem install loc_counter

The gem installs a single executable loc_counter.

If you want to count LOCs in your Rails app or in a gem, you can just pass a path to that project's directory to loc_counter:

$ loc_counter /path/to/project
48 files processed
Total     1826 lines
Empty     331 lines
Comments  372 lines
Code      1123 lines

In 'project mode' it scans app, bin, config, lib and top-level directories of your project, processing the following files:

• Capfile
• Gemfile
• Rakefile
• *.gemspec
• *.rake
• *.rb
• * in bin directory

You can also give loc_counter any files you want to measure.

$ loc_counter ~/*.rb              
5 files processed
Total     118 lines
Empty     27 lines
Comments  4 lines
Code      87 lines

If you want to contribute to the project, fork the repository, push your changes to a topic branch and send me a pull request.

loc_counter is tested under MRI 1.8.7, 1.9.2 and 1.9.3. If something is working incorrectly or not working at all in one of these environments, this should be considered a bug. Any bug reports are welcome at Github issues.
