@dcdenu4 could you test this PR ?

You can use this branch as goanpeca/setup-miniconda@enh/channels

@goanpeca I tested it on my simple use case and it appears to work properly and pull from the added channels. It looks like for channels: conda-forge, anaconda , the priority order is anaconda, then conda-forge. It's a little counter intuitive to me, as I would think the first thing I list has the greatest priority, but if it's documented well then it doesn't really matter.

Thanks for this!

That order is weird indeed I think I have an issue there so that is not right.

I will need to look i to it then

[goanpeca]

Ok I knew that could be an issue https://zellwk.com/blog/async-await-in-loops/

I need to change to a normal for otherwise the order is not guaranteed.

And I learned something new about Js :-p

[goanpeca]

@dcdenu4 fixed the issue now. It should be in the right order now! Could you please check before the merge? (at lest on two consecutive builds?)

[dcdenu4]

@goanpeca Just ran two tests and they both use the first channel in my list, conda-forge in my case. So this is expected and different than prior when it was using anacaonda, my 2nd specified channel. Looks good!

Thanks for testing @dcdenu4 making a release soon ;-)
