Installation

Simply install with npm by running npm install gulp-jslint.

Usage

var gulp = require('gulp');
var jslint = require('gulp-jslint');

gulp.task('default', function () {
    return gulp.src(['source.js'])
            .pipe(jslint({ /* this object represents the JSLint directives being passed down */ }))
            .pipe(jslint.reporter( 'my-reporter' ));
});

If you would like to specify a custom jslint edition to use, set the property 'edition' in your directives object. These versions should follow what the package node-jslint expects or this property can be set to a pre-loaded jslint function.

Directives

All directives being passed to the jslint() function are standard JSLint directives (for a list of directives, see the official JSLint docs).

However, to supply a list of global variables for your code, use the directive 'predef' or 'global' like so ('global' is an alias of 'predef' but 'predef' will be prefered since it is the official JSLint standard):

gulp.task('default', function () {
    return gulp.src(['source.js'])
            .pipe(jslint({
                predef: [ 'a_global' ],
                global: [ 'a_global' ]
            }));
});

Please see gulpfile.js for a more extensive sample gulpfile.

Reporters

By default, two reporters are provided by gulp-jslint. The first is the default reporter (appropriately named 'default') and the second report is the popular 'jshint-stylish' (named 'stylish').

To use either of these reporters, provide the name of the reporter followed by whatever arguments they expect to the function jslint.reporter().

For example:

gulp.task('default', function () {
    return gulp.src(['source.js'])
            .pipe(jslint())
            .pipe(jslint.reporter('default', errorsOnly))
            .pipe(jslint.reporter('stylish', options));
});

It's probably a good idea to use something like path.basename() on the file property to avoid lots of garbage in the command-line (i.e. path.basename('/path/to/index.js') === 'index.js').

Custom Reporters

Custom reporters should be either be synchronous or streams. Either way, the reporter will receive a results object and can output its report onto the console/logfile the way it wishes.

The results object will contain the following properties:

• filename: the absolute path to the file being linted.
• success: a boolean value representing whether the linting passed.
• errors: an array of JSLint errors. Each element will contain the properties:
  • name: the string 'JSLintError'.
  • column: the column number of the error.
  • line: the line number of the error.
  • code: a code relating to the error.
  • message: a message describing the error.
