Rethink structured-haskell-mode keybindings

[EDmitry]

I have been trying to wrap my head around structured haskell mode. By default ) and ( are mapped to movements. The problem is that o and O functionality is missing because you have to choose the right block before you can create a newline otherwise the indentation will be incorrect. I have found that binding ")" in normal mode to switch to insert mode and do shm/close-paren improved the workflow a bit. I have tried doing that without switching to insert mode but then the cursor is at the wrong position in the end of line (common evil-mode issue).

What's interesting though is that basically structured-haskell-mode is trying to emulate vim text objects in some way. It already has some sort of selection which is different from evil's selection. I wonder if there is a better way to integrate it with evil-mode.

Also, maybe we could use some ideas from evil-lisp-state. It seems like SHM is a similar concept but has less actions.

I agree that SHM is not doing much in spacemacs. I wonder where would be a good place to work on it?

• Spacemacs
• evil-lisp-mode
• A new evil-haskell-mode

I'd love to know how SHM author @chrisdone thinks it should work.

A new evil-haskell-mode would be great 👍

I am using Spacemacs with emacs editing style and for me shm is priceless. But having evil-haskell-mode will not hurt me - I will still use shm 😄

We finally removed it from haskell layer in develop branch.
It may come back in a better shape at some point :-)
