# Usage examples ## Wildcards In this example, running `grunt jshint:all` (or `grunt jshint` because `jshint` is a [multi task][]) will lint the project's Gruntfile as well as all JavaScript files in the `lib` and `test` directories and their subdirectores, using the default JSHint options. ```js // Project configuration. grunt.initConfig({ jshint: { all: ['Gruntfile.js', 'lib/**/*.js', 'test/**/*.js'] } }); ``` ## Linting before and after concatenating In this example, running `grunt jshint` will lint both the "beforeconcat" set and "afterconcat" sets of files. This is not ideal, because `dist/output.js` may get linted before it gets created via the [grunt-contrib-concat plugin](https://github.com/gruntjs/grunt-contrib-concat) `concat` task. In this case, you should lint the "beforeconcat" files first, then concat, then lint the "afterconcat" files, by running `grunt jshint:beforeconcat concat jshint:afterconcat`. ```js // Project configuration. grunt.initConfig({ concat: { dist: { src: ['src/foo.js', 'src/bar.js'], dest: 'dist/output.js' } }, jshint: { beforeconcat: ['src/foo.js', 'src/bar.js'], afterconcat: ['dist/output.js'] } }); ``` ## Specifying JSHint options and globals In this example, custom JSHint options are specified. Note that when `grunt jshint:uses_defaults` is run, those files are linted using the default options, but when `grunt jshint:with_overrides` is run, those files are linted using _merged_ task/target options. ```js // Project configuration. grunt.initConfig({ jshint: { options: { curly: true, eqeqeq: true, eqnull: true, browser: true, globals: { jQuery: true }, }, uses_defaults: ['dir1/**/*.js', 'dir2/**/*.js'], with_overrides: { options: { curly: false, undef: true, }, files: { src: ['dir3/**/*.js', 'dir4/**/*.js'] }, } }, }); ```
