Hard to distinguish warnings and errors

[ad-si]

At the moment it's really hard to visually distinguish warnings from errors:

It would be cool if the difference was more prominent. E.g. through using different colors and adding ASCII art for sectioning the output.

Maybe something like this (pseudocode for coloring):

<yellow>=== Warning 50 of 50:==================================================</yellow> 

  at src/Neodoc/Evaluate/Reduce.purs:97:16 - 97:17 (line 97, column 16 - line 97, column 17)

…

<red>=== Error 1 of 5===========================================================</red>

  at src/Neodoc/ArgParser/Parser.purs:685:1 - 740:48 (line 685, column 1 - line 740, column 48)

    An anonymous function argument appears in an invalid context.

…

What do you think?

You might try purescript-psa for console based output.

I'm seeing this as output from spago build. Can I use psa with spago?
But this issues is about improving the default anyways 😉

[natefaubion]

purescript/spago#252

[hdgarrood]

psa is a good option for now, but I think this is worthy of considering; I'm also keen on improving the defaults. I'd be up for folding basically everything that psa does back into the main compiler. See also: #1898, #2308.

[natefaubion]

Yes, as the author of psa, I too would prefer it was just a compiler default.

[ad-si]

Look at this, psa does already seem to be the default for spago 😳:

$ spago --help
…
  -P,--no-psa              Don't build with `psa`, but use `purs`
…

But it doesn't seem to be used 🤔

[natefaubion]

Maybe it needs to be globally installed?

[hdgarrood]

I think it needs to be on your PATH.

[ad-si]

Ah yes, either spago and purescript-psa are both installed locally or both globally, but the global spago doesn't pick up a local purescript-psa. Should maybe be implemented. Tools like webpack use the local version if they find one iirc.

For anyone reading this, if you need to use spago with psa, simply install both globally. They will work together automatically.
