Tim van der Lippe 6d109a9d45 Update Mocha to 8.3.0
This also adds Python-2.0 to the list of accepted licenses.

Lastly, it fixes a bug where the package.json files were incorrectly
reordered. For the `exports` of a particular package, the order that
the entrypoints are defined in is crucial. Therefore, we should not
alter the order of entrypoints and instead maintain the originally
defined ordering. We can use an `OrderedDict` to ensure that Python
always loads the JSON files in the same order.

merge-stream

Merge (interleave) a bunch of streams.

build status

Synopsis

var stream1 = new Stream();
var stream2 = new Stream();

var merged = mergeStream(stream1, stream2);

var stream3 = new Stream();
merged.add(stream3);
merged.isEmpty();
//=> false

Description

This is adapted from event-stream separated into a new module, using Streams3.

API

mergeStream

Type: function

Merges an arbitrary number of streams. Returns a merged stream.

merged.add

A method to dynamically add more sources to the stream. The argument supplied to add can be either a source or an array of sources.

merged.isEmpty

A method that tells you if the merged stream is empty.

When a stream is "empty" (aka. no sources were added), it could not be returned to a gulp task.

So, we could do something like this:

stream = require('merge-stream')();
// Something like a loop to add some streams to the merge stream
// stream.add(streamA);
// stream.add(streamB);
return stream.isEmpty() ? null : stream;

Gulp example

An example use case for merge-stream is to combine parts of a task in a project's gulpfile.js like this:

const gulp =          require('gulp');
const htmlValidator = require('gulp-w3c-html-validator');
const jsHint =        require('gulp-jshint');
const mergeStream =   require('merge-stream');

function lint() {
  return mergeStream(
    gulp.src('src/*.html')
      .pipe(htmlValidator())
      .pipe(htmlValidator.reporter()),
    gulp.src('src/*.js')
      .pipe(jsHint())
      .pipe(jsHint.reporter())
  );
}
gulp.task('lint', lint);
