Example

The below example will result in 2 copies of each stylesheet, one LTR stylesheet and one RTL stylesheet (with "-rtl" appended to the filename before the extension). The example uses autoprefixer, this is just an example of other CSS post-processing being used before cssjanus.

var gulp = require('gulp');
var autoprefixer = require('gulp-autoprefixer');
var cssjanus = require('gulp-cssjanus');
var rename = require('gulp-rename');

gulp.task('styles', function () {
    return gulp.src(['/styles/*.css')
        .pipe(autoprefixer(["last 2 versions", "> 1%"])) // Other post-processing.
        .pipe(gulp.dest('dist')) // Output LTR stylesheets.
        .pipe(cssjanus()) // Convert to RTL.
        .pipe(rename({ suffix: '-rtl' })) // Append "-rtl" to the filename.
        .pipe(gulp.dest('dist')); // Output RTL stylesheets.
});

Alternatives

gulp-rtlcss - based on rtlcss instead of cssjanus.
