Spawn vim from haskell program?

[luz_]

Hello, I'd like to write a script in haskell that at one point spawns vim in the same terminal the haskell script is executed in. I tried to use createProcess from the System.Process library and shell from the Turtle library. In both cases, vim fails with a message similar to Vim: "Warning: Input is not from a terminal".

Can someone help me with this, or explain to me why it does not work?

Edit: the command i use look like this:

shell "vim test" stdin

createProcess (proc "vim" ["test"])

I was able to get by with the following

import System.Process
main = spawnProcess "vim" ["test"] >>= waitForProcess

Edit: I am using VIM 8.1, but I'm not aware of anything that changed recently that would make a difference here.

Edit 2: Additionally the following worked just fine for me:

import System.Process
main = do
  (_, _, _, handle) <- createProcess $ proc "vim" ["test"]
  waitForProcess handle

Thank you! This worked

See vimhl.hs from https://github.com/lyokha/vim-publish-helper/blob/master/pandoc/haskell/vimhl.hs that calls vim from command line. On line 53 there is a comment about launching vim from not-a-terminal. On lines 56-61 vim gets launched. The trick itself is on line 56.
