When additional arguments, not task names, are used, these arguments should be added to the child process argument array.

If I call

gulp --production

I would expect --production to be passed as an argument to the child processes.

When using non-boolean command line arguments e.g. "--tag foo", it only passes the first component e.g. "--tag" to child processes.

yargs is probably the easiest way to handle all the parsing

Any plan to port this to gulp 4 ?

Gulp 4 have gulp.series and gulp.parallel to create the tasks dependency trees, but parallel don't uses threads/processes to execute slow tasks on different CPUs.

Hi!

One of the things I need to do is run webpack and watch for file changes, another I need to do is fire up dynamodb local, another one is to keep an electron app running... all of these spit out debugging information that I may need.

Ideally, I would use your plugin and combine all their output in one single stdout that I can prefix with an identifier:

[electron] debug from the app...
[webpack] reloaded stuff
[dynamodb] requested record X

is this something I can do with your plugin? (and if so, how?)

Thanks for your hard work!

Thanks for writing gulp-multi-process, it really speeds up my builds!

When I use gulp-multi-process on windows though, an error is thrown:

Would be great if gulp-multi-process would work on windows too.

The exit code of the spawned processes are not currently being checked in any way, meaning a failed sub-task will not be reported to the parent process, which will still exit with an exit code of 0.

This is particularly an issue when this module is used in a CI job running unit tests etc. as the tests could fail and the build will still pass.
