Issue using type-at in spacemacs

[fatlazycat]

Hi, not sure where the issue lies, within spacemacs or haskell-mode hence this issue.

Have raised syl20bnr/spacemacs#1472

It appears something is sending the wrong columns to the type-at command.

Any ideas ? Could you help point me in the direction to debug this ?

Thanks

@fatlazycat can you M-x toggle-debug-on-error to enable debugging, then run type-at command and post here debugger output?

[fatlazycat]

Would that goto the haskell-process-log ?

Is any different from the output

λ> :type-at /Users/graham/Development/GitHub/fatlazycat/NICTA-course/src/Course/ListZipper.hs 240    29 240 31 xs

*Course.ListZipper| *Course.ListZipper| *Course.ListZipper| xs :: a -> List a -> List a
λ> :type-at /Users/graham/Development/GitHub/fatlazycat/NICTA-course/src/Course/ListZipper.hs 240 31 240 32 xs

*Course.ListZipper| *Course.ListZipper| *Course.ListZipper| <interactive>:1:1-2: Not in scope: ‘xs’

@fatlazycat do you have some error messages when invoking type-at command or you just have unexpected result? In first case debugger output would be really helpful.

Also, please clarify output you posed: which command you run manually or both of them? I see different column numbers (29 -> 31, 31 -> 32) in above commands, can you also show me line 240?

[fatlazycat]

Hmm, apologies seem to be getting myself confused.

They changed the default emacs binding but their standard binding m h t now works showing the output in the haskell-process-log.

It just doesn't appear anywhere else such as the gutter, which I assume is a spacemacs / my config issue.

[geraldus]

@fatlazycat if it works it's good. I've made some improvements on haskell-process-show-type-at recently, so if it is doesn't work I want to know. Anyway, if you're facing any issues with haskell-mode please feel free to report them!

I have the same issue with result printed only in haskell-process-log. Nothing is printed at the bottom of emacs (whatever it's called).

[fatlazycat]

@wedens In a non-spacemacs emacs ?

[wedens]

@fatlazycat yeah. non-spacemacs

[fatlazycat]

@geraldus hmm, how do you see the results ?

I'll try a get the most minimal config for emacs sorted to try and narrow it down.

[geraldus]

Hey guys, sorry I also do not see results. Please excuse me I didn't made proper checks of echo area, I have presentation mode enabled and I can confirm that at least it works (and echo area stuff worked fine just not long ago)! Let me see what's happening and why it's become broken.

[geraldus]

Well, likely haskell-utils-echo-or-present¹ is a culprit, but it is so simple that I have no idea what's going wrong!

[geraldus]

Cool! I have a hotfix! There was missing parentheses, I'll make a PR right now.

[fatlazycat]

😀 great thanks!
