Incorrect indentation in haskell-mode

[codygman]

I'm not sure if this is an error with hi2, if you need to modify behavior of evil-open-below in Haskell mode, or both. This is a vanilla Haskell mode install on nixos but I've also reproduced on a vanilla Ubuntu install.

I think this is a bug/something to be reported for hi2. I tend to agree, I find this behavior quite annoying, though I can see the sense in it...

What's the status of this bug ?

[ocharles]

I don't think it's a spacemacs bug - if anything it should be reported at https://github.com/haskell/haskell-mode

[ajnsit]

Is there a way to be certain if it's haskell-mode or spacemacs which has the bug? I see the same issue on a vanilla install of spacemacs on ubuntu. In fact the symptoms are much worse because a lot of times, the current line will also get automatically indented on pressing enter. But I don't see the same issue on vanilla emacs with haskell mode.

Have you tried building from master? I think this fixed it:

I have found the behavior of evil-open-below quite counter-intuitive/annoying in general.
Is there an easy way to have the normal 'vim' behavior' (i + RET) back ?

Umm... evil-open-below is still exhibiting the same behavior if I do not enable structured-haskell-mode. However structured-haskell-mode seems to have issues with inserting brackets in INSERT state. It's quite annoying.

@d12frosted And this...

[d12frosted]

Well, in haskell-indentation-mode (which is used in Spacemacs) behaviour is the same. The idea of using tab on region with this indentation mode enabled is that it allows you to move region left or right by pressing tab or S-tab repeatable without marking region again. Notice, what is written in echo area when you press = with active region. And looks like, we should mimic this behaviour somehow. When I try pressing = in normal state and then tab - nothing happens. When I press = again - region is not indented further. I am not sure how to mimic this thing, cause I don't use vim editing style.

But I don't see the same issue on vanilla emacs with haskell mode.

@ajnsit Have you enabled haskell-indentation-mode or turn-on-haskell-indentation before testing it?

@TheBB And here 😄

[d12frosted]

Oh, forgot to share this. 😄

[StreakyCobra]

Any update on this issue?

[d12frosted]

@StreakyCobra see related PR (#3586).

But I believe that it's 'wontfix'.

[StreakyCobra]

Oh, I didn't saw it, thx.

[StreakyCobra]

Probably the same problem as in #5010. Problem with indentation has been reported upstream.

[d12frosted]

Upstream issue is not fixed yet.

Reference: haskell/haskell-mode#1265 (original report haskell/haskell-mode#896 was closed in favour of haskell/haskell-mode#1265).

[fiveNinePlusR]

seems like this should be closed as it's an upstream issue.
