How can I use a glob to ignore files that start with an underscore?

Question

I am using this file matching in gulp:

\'content/css/*.css\'

But I would like to only include the files that do not start

Answer 1

If Gulp wildcards are like shell wildcards:

content/css/[^_]*.css

The ^ at the beginning of a character set means to match any characters not in the set.

Answer 2

You could use this regex.

content/css/[^_].*\.css

Add $ at the last if necessary.

Answer 3

You can add a second glob whitch will filter files or folders with an underscore.

For ignore folders I use:

gulp.src(['./src/**/*.html', '!**/_*/**'])

'!**/_*/**' will filter folders that start with an underscore.

Answer 4

Use this plugin https://github.com/robrich/gulp-ignore

var gulpIgnore = require('gulp-ignore');
var condition = '_*.css'; //exclude condition

gulp.task('less', function() {
  gulp.src('content/less/*.less')
    .pipe(gulpIgnore.exclude(condition))
    .pipe(less())
    .pipe(gulp.dest('/dist/'));
});

I think gulp supports file glob not full-regex, But You can give a try to content/css/[^_]*.less
