This code snippet helps in reply to a JSHINT pull request here: https://github.com/jshint/jshint/pull/1221. The code is part of a node.js file that programmatically looks through a project's files and outputs the results of jshint for each file.

jshint.js

//get node specific and less strict options from .jshintrc file
var jsHintOPTIONS = JSON.parse(JSON.minify(fs.readFileSync('./.jshintrc', 'utf8')));

/*Purpose: To run jsHint on a str.js
  Params: error message passed up from callback caller, string is path and filename to a .js file
  Output: Outputs to console a very similar output as "$ jshint myfile.js". After a file finishe with errors, script exits with code 1
  Async: false - because call to readFile uses readFileSync version 
*/
function hint(err, str) {
  if (err) {
		console.log(err);
	} else {
		//var fileContents = fs.readFile(str, 'utf8', )
		var result = jshint.JSHINT(readFile(str), jsHintOPTIONS);
		if (result) {
			console.log("jsHinting " + str + "...OK!");
		} 
		else {
			var jshErrors = jshint.JSHINT.data().errors;
			for (var i = 0; i < jshErrors.length; i++) {
				//var errMsg = jshError;
				var errMsg = str + ": line " + jshErrors[i].line + ", col " + jshErrors[i].character + ", " + jshErrors[i].reason;
				console.log(errMsg);				
			}
			process.exit(1);
		}
	}
