var parse = require('parse-diff');
var diff = ''; // input diff string
var files = parse(diff);
console.log(files.length); // number of patched files
files.forEach(function(file) {
console.log(file.lines.length); // number of hunk/added/deleted lines
// each line in file.lines is a string
console.log(file.deletions); // number of deletions in the patch
console.log(file.additions); // number of additions in the patch
});
