lint-runner

Jake JsHint provides a convenient front-end to JSHint, a linter for Javascript. It should also work for JSLint.

You're welcome to use the runner for your own projects. (See license below.) This project was just a quick hack, so I can't vouch for its robustness, but it should work in most cases. One flaw I'm aware of is that it assumes all files are UTF8-encoded, which may not be true for your system. It also has no exception handling.

The runner is a Node.js module. It exposes three functions:

  validateSource(sourceCode, [options], [globals], [description])

Run JSHint on raw source code and output the results to the console (using console.log()). If the code failed to validate, the details are also output to the console. If the code succeeded, a one-line ok message is displayed. If provided, description will be prepended to the pass/fail message, like this: description ok.

This function returns true if the code was valid or false if errors were found. options and globals are passed through to JSHint.

  validateFile(filename, [options], [globals])

Same as validateSource, except that the source code is read from a file.

  validateFileList(fileList, [options], [globals])

Validates multiple files and outputs the results for each one. All files are validated even when some fail.

fileList is expected to be an array. This function returns true if all files are valid and false otherwise.

Running Tests

first:

 $ npm install -d

then:

 $ ./jake.sh

Super simple to use

Jake JsHint is designed to be the simplest way to lint your project from a jake script.

desc("Lint the code");
task("lint", [], function() {
  var files = new jake.FileList();
  files.include("lib/*.js");
  files.include("test/*.js");
  files.include("build/*.js");
  files.include("./*.js");
  files.exclude("node_modules");
  
  var options = {
    node: true
  };

  var globals = {
    describe: false
  };

  var pass = lint.run(files.toArray(), options, globals);
  if (!pass) fail("Lint failed");
});

For a full list of JsHint options check here.

Here is a suggested set:

var options = {
    bitwise: true,
    curly: false,
    eqeqeq: true,
    forin: true,
    immed: true,
    latedef: true,
    newcap: true,
    noarg: true,
    noempty: true,
    nonew: true,
    regexp: true,
    undef: true,
    strict: true,
    trailing: true,
    node: true
  };

  var globals = {
    describe: false,
    it: false,
    beforeEach: false,
    afterEach: false
  };
