Toggle warnings off and on?

[xged]

How about SPC e w to toggle warnings off/on permanently?

[codygman]

I'd be careful to not ignore too many warnings and advise enabling incomplete-patterns by putting :set -fwarn-incomplete-patterns in your ~/.ghci configuration file (on linux and mac, not sure where windows ghci config is).

You can also put any of these in your ghci configration file: https://downloads.haskell.org/~ghc/latest/docs/html/users_guide/options-sanity.html

I think just giving you a list of warnings would answer your question, but overall do you a disservice. What are you trying to hide or get rid of that is bothering you?

[xged]

Turn all warnings off for most of the time (not always) would not hurt. Editing ~/.ghci is useful to remove (specific) warnings completely, but that is not what I want.

P.S. Writing :set -w did not change the way flycheck behaves for me.

From a cursory check it doesn't seem possible in flycheck to disable showing all warnings. You can turn off the individual checkers that produce them, or possibly configure the checkers themselves, but there doesn't seem to be a flycheck setting for: I only want to see errors, not warnings.

@lunaryorn?

Removing the Haskell label as this is actually a flycheck feature request.

[d12frosted]

@TheBB yeah, good call.

@TheBB You can filter the error list by level, see flycheck-error-list-minimum-level. A similar option exists for navigation, too. There's no way to inhibit warnings from being shown in the buffer itself, though, and I don't plan to add such a feature.

[TheBB]

Okay, so the answer becomes:

• To remove warnings from the error list, see ☝️
• To remove warnings from the modeline, set spaceline-flycheck-warning-p to nil (in develop)
• To remove warnings in general (also from the buffer), you can advise flycheck-relevant-error-p.

We can possibly include such an advise as a toggle.

@TheBB You forgot navigation 😉

As for the advice, speaking as the maintainer of Flycheck I'm strictly against any advices for Flycheck functionality—actually, against any advises at all, fwiw. If you add advises for Flycheck I'll assume that you also take responsibility for all Flycheck issues that appear in Spacemacs, for I'll refuse to deal with them.

I'm sorry for the harsh words, but I've had my share of fun with broken and crappy advises, and I just don't feel like dealing with that anymore ☺️

If you'd like to have this feature then please implement it in Flycheck itself. I said that I don't plan to add such a feature myself—I just don't need it—but that shouldn't stop anyone from giving it a shot and opening a corresponding pull request for Flycheck. It's a reasonable feature, and nothing stands against merging it ☺️

[TheBB]

Okay, I interpreted your "don't plan to add such a feature" the wrong way, then.

[swsnr]

@TheBB I see, I'm sorry for the misunderstanding 😊 I should have said that in a different way. Sorry
