gulp-ignore

gulp-ignore !status
===========

Include or exclude gulp files from the stream based on a condition

Usage

1: Exclude things from the stream

Exclude things from entering the stream

![][glob]

``javascript
var uglify = require('gulp-uglify');

gulp.task('task', function() {
gulp.src(['.//*.js', '!./node_modules/'])
.pipe(uglify())
.pipe(gulp.dest('./dist/'));
});
`

Grab all JavaScript files that aren't in the node_modules folder, uglify them, and write them.
This is fastest because nothing in node_modules ever leaves gulp.src()


2: Remove things from the stream

Remove from here on

![][exclude]

`javascript
var gulpIgnore = require('gulp-ignore');
var uglify = require('gulp-uglify');
var jshint = require('gulp-jshint');

var condition = './gulpfile.js';

gulp.task('task', function() {
gulp.src('./*/.js')
.pipe(jshint())
.pipe(gulpIgnore.exclude(condition))
.pipe(uglify())
.pipe(gulp.dest('./dist/'));
});
`

Run JSHint on everything, remove gulpfile from the stream, then uglify and write everything else.

3: Filter only matching things

Include from here on

![][include]

`javascript
var gulpIgnore = require('gulp-ignore');
var uglify = require('gulp-uglify');
var jshint = require('gulp-jshint');

var condition = './public/**.js';

gulp.task('task', function() {
gulp.src('./*/.js')
.pipe(jshint())
.pipe(gulpIgnore.include(condition))
.pipe(uglify())
.pipe(gulp.dest('./dist/'));
});
`

Run JSHint on everything, filter to include only files from in the public folder, then uglify and write them.


4: Conditionally filter content, include everything down-stream

Condition

![][condition]

`javascript
var gulpif = require('gulp-if'); // This is gulp-if, not gulp-ignore
var uglify = require('gulp-uglify');

var condition = function(file) {
// Only files whose contents match a pattern
return /a pattern/g.test(String(file.contents));
};

gulp.task('task', function() {
gulp.src('./src/*.js')
.pipe(gulpif(condition, uglify()))
.pipe(gulp.dest('./dist/'));
});
`
Only uglify the content if the condition is true, but send all the files to the dist folder.
