Run grunt jshint before every commit. The commit fails if any warnings/errors are generated. Helps avoid "jshint fix" style commits

pre-commit

#!/usr/bin/env node
var exec = require('child_process').exec;
 
// Runs the build task, in our case `grunt jshint`
exec('grunt jshint', function (error, stdout, stderr) {
 
  // Build task output might be useful to the developer so let's print it
  // We could also log it in a file
  console.log(stdout);
 
  // Depending on the result of the build, either print the error
  // or exit successfully
  var exitCode = 0;
  if (error) {
    console.log('Fix jshint errors before committing');
    console.log(stderr);
    exitCode = -1;
  }
 
  process.exit(exitCode);
});
