Can Gulp overwrite all src files?

by

I can think of two solutions:

  1. Add an option for base to your gulp.src like so:

    gulp.src([...files...], {base: './'}).pipe(...)...

    This will tell gulp to preserve the entire relative path. Then pass './' into gulp.dest() to overwrite the original files. (Note: this is untested, you should make sure you have a backup in case it doesn’t work.)

  2. Use functions. Gulp’s just JavaScript, so you can do this:

    [...files...].forEach(function(file) {
    var path = require('path');
    gulp.src(file).pipe(rename(...)).pipe(gulp.dest(path.dirname(file)));
}

    If you need to run these asynchronously, the first will be much easier, as you’ll need to use something like event-stream.merge and map the streams into an array. It would look like

    var es = require('event-stream');

...

var streams = [...files...].map(function(file) {
        // the same function from above, with a return
        return gulp.src(file) ...
    };
return es.merge.apply(es, streams);
