Colorize "elm-pages build" output

[ad-si]

Looks a little blunt right now 😉

Hey! Thanks for reporting the issue, and good point.

Looks like it's related to this issue: rtfeldman/node-elm-compiler#91.

That issue points out a hack that provides a workaround (by compiling it a second time if there's a failure). I guess I could fork the code and use that 🤷‍♂ Not great, but it would be nice to have nicely formatted error messages.

Yesterday someone posted a solution without compiling twice: rtfeldman/node-elm-compiler#91 (comment)
Would this work for elm-pages?

[dillonkearns]

Wow, nice, thanks for that, I didn't see the new comment yesterday.

I'll see if I can fork that and try using that patch.

I'm both using the node-elm-compiler directly, and indirectly through the https://github.com/elm-community/elm-webpack-loader. But I can at least see if we can fix it in that one spot (which would fix the case that you took a screenshot of).

It works!

[ad-si]

Awesome 👏, thanks!

Just published! 😁 https://github.com/dillonkearns/elm-pages/blob/master/CHANGELOG-NPM.md#128---2020-02-08

Note the caveat I mention in the changelog:

Note, this patch still hasn't propogated through to elm-webpack-loader (see elm-community/elm-webpack-loader#166).
So there may still be non-colorized output for errors as you make changes while the dev server is running.

Hopefully this gets fixed upstream in node-elm-compiler and then elm-webpack-loader updates to pull in that change so we can get colorized output at that stage as well.
