Feature Request: Add haskell REPL support for GHCI about neoterm HOT 8 CLOSED

Hello @alok, unfortunately, I know nothing of Haskell. There are some examples on the project's readme about how to add a new REPL. If possible, open a pull request and I'll be glad to merge it. 😄

I don't know Haskell very well (read: at all) but I think simply adding this to ftdetect/set_repl_cmd.vim should do it:

" Haskell GHCi
au VimEnter,BufRead,BufNewFile *hs,
      \ if executable('ghci') |
      \   call neoterm#repl#set('ghci') |
      \ endif

I don't know whether GHCi's commands that begin with :, e.g. :def, will confuse Vim though. ¯_(ツ)_/¯

from neoterm.

That works decently well, though it can't do multiline commands or function declarations since GHCI requires those have the word "let" in front of them. I'm going to look at vim-slime for some inspiration.

Why you can't use multiline commands an let functions with that solution?

I encountered that problem just now. Multi-line code in ghci must be fenced with :{ and :}. So, for example, if I visually select the lower 3 lines of the following code:

-- Compute the length of a list of Integers.
intListLength :: [Integer] -> Integer
intListLength []     = 0
intListLength (x:xs) = 1 + intListLength xs

it needs to be send to ghci in this way:

:{
intListLength :: [Integer] -> Integer
intListLength []     = 0
intListLength (x:xs) = 1 + intListLength xs
:}

from neoterm.

#274 introduced the possibility to have lang-specific REPL senders. Which would be helpful to solve this problem.
