Use the binary:

$ c2t

LOC Code: 59
LOC Test: 14

Wow, 24%, I hope you do better!

Or use it from JavaScript:

var getRatio = require('code-to-test-ratio');
 
getRatio(__dirname, function (err, ratio, loc) {
  if (err) throw err;
  console.log('Code to test ratio: ' + ratio);
  console.log('LOC Code: ' + loc.code);
  console.log('LOC Test: ' + loc.test);
});

API

getRatio(directory[, opts], fn)

Get the code-to-test ratio for all files in directory and call fn with (err, ratio, loc).

By default everything in node_modules and example is ignored. You can overwrite this by passing an Array of path segments to opts.ignore.

By default everything that has an extension that is not js is ignored. You can overwrite this by passing an Array of valid extensions to opts.source.
