SpaceNeovim status for general development and Haskell especially

[chshersh]

I don't know where to ask, so I'm opening my issue here. I'm using spacemacs currently as my development environment for Haskell and I'm okay with it. But I would like to give SpaceNeovim a try. Not everything is clear from this package, so I would like to know, what is supported from the following list:

General

• [ ] Trailing whitespace cleaner
• [ ] magit support
• [ ] org-mode
• [ ] ido for file browsing
• [ ] git diff highlight on the left gutter (or some sort of diff highlighting)

Haskell

• [ ] At least basic autocompletion (not necessary by type, just by name prefix would already ok)
• [ ] Syntax highlighting for .hs and .cabal files
• [ ] Ability to run some executables automatically on file-save (like code-formatters)
• [ ] Support for go-to-definition via TAGS or something like that (there's hasktags for Haskell)

Not everything is required to develop. But at least it's good to know what is missing and what is there 🙂

Thanks in advance for research about current state of the ecosystem!

Hi! Thanks for the question :)

I think you will be able to get a much better overview by checking out the layers repository. And you can of course always install additional plugins via ExtraPlugin 'githubuser/repo' (as shown in the README).

I'll try to tackle them the best I can, ticking off the ones that are directly supported by layers, and giving recommendations for those that are not:

General

• [x] Trailing whitespace cleaner --> This usually will happen via formatters configured using the plugin that +tools/format uses. Alternatively there's vim-better-whitespace.
• [ ] magit support --> The +scm/git layer sets up vim-fugitive which you can use to manage git. Unfortunately, it's no magit, since that's pretty emacs specific. You might be able to come close with vimmagit though, e.g. as an ExtraPlugin.
• [ ] org-mode --> I have never really gotten into org-mode, although I keep hearing great things about it. There seems to be vim-orgmode which covers some (most?) of the functionality.
• [x] ido for file browsing --> I haven't used ido but we do have a few layers for fuzzy file searching, e.g. +nav/fzf and +nav/fuzzy
• [x] git diff highlight on the left gutter (or some sort of diff highlighting) --> That is taken care of by the +scm/git layer via vim-gitgutter.

Haskell

• [x] At least basic autocompletion (not necessary by type, just by name prefix would already ok) --> There is the choice of a few completion engines from +completion/deoplete and +completion/ncm2 to using the one that the LSP layer +tools/language-server provides.
• [x] Syntax highlighting for .hs and .cabal files --> Included via +lang/haskell
• [x] Ability to run some executables automatically on file-save (like code-formatters) --> You would use +tools/format for formatters, and then you can of course always set up any Vim autocommand to run on save. Linters also run on save, and there are a few options there such as +checkers/ale (which I use), +checkers/syntastic and +checkers/neomake.
• [x] Support for go-to-definition via TAGS or something like that (there's hasktags for Haskell) --> IIRC the only layer that supports go-to-def currently is if you use the LSP layer +tools/language-server and your LSP server supports it (which HIE, the Haskell IDE Engine does).

Vim, like Emacs, is highly configurable. Some of these could definitely be made into layers, if need be. I currently just make them as I go, based on my own demands and what people request :)

If there's anything else I can help with, please do not hesitate to ask!
