Support for gulpfile written in ES6

[cmwd]

Gulp since version 3.9 supports gulpfile written in es6 (babel). It would be great if gulp-chug could support babel. Right now I getting syntax error. Update dependency to new version of gulp didn't help.

I agree it would be nice if it would "just work" out of the box, but in the meantime I found a workaround using the nodeCmd option to use babel-node:

return gulp.src(path.resolve(__dirname, '../other-project/gulpfile.babel.js'))
    .pipe(chug({
        // Specify babel-node for ES6 support
        nodeCmd: path.resolve(__dirname, 'node_modules/.bin/babel-node.cmd')
    }))
    .on('error', gutil.log);

The .cmd after babel-node is needed on Windows, but you'd want to drop that on any other OS. If you don't have babel-node installed,

npm i --save-dev babel-cli

should pull it down.

I came across this issue today and @03eltond workaround did work but it shouldn't be needed. I already have a .babelrc in the directory with the gulp file. I ended up just spawning my own process and it actually worked better and faster than this plugin.

import { exec } from 'child_process';
import map from 'map-stream';

function buildModules() {
  return gulp.src(['./modules/*/gulpfile.babel.js'])
          .pipe(map(function (file, cb) {
            exec('gulp --gulpfile ' + file.path, function(error, stdout, stderr) {
              console.log(stdout);
              cb();
            });
          }));
}
buildModules.displayName = 'build';
gulp.task(buildModules);

May help someone else

Huh that's clever, thanks for sharing
