Remove dependence on ghciInitialPrompt

[sjcobb2022]

Hi there,

I've been writing a good amount of haskell recently so I have decided to put some time into developing some tooling for my workflow. I have added haskell-debug-adapter to the mason-registry for neovim. As of now, I am integrating this into my config.

My major issue for the past few hours is determining why my config wasn't working. I had set everything up as intended according to the nvim-dap docs and the docs here, and nothing seemed to be working. I then realised that the ghciInitialPrompt was probably incorrect, and I proceeded to fix it.

In my opinion this makes it quite hard for users to make a config generic in any sense, especially as the default value ("Prelude>") is not the default for a fresh install of stack/ghci with ghcup.

Is there any way this issue could be addressed, or is it a necessary evil?

Which pages are you referring to?

I can maintain that docs.
ghciInitialPrompt should be ">".

Sorry when I meant the docs here I did mean the hdx4vim yes.

Whilst setting ghciInitialPrompt to ">" is a good workaround, if a user has set a custom prompt in their ghci config then it may not properly detect. For example I had my ghc prompt set as "λ: ".

Hi.
Currently hda can't automatically get the custom prompt from .ghci file.
As a new feature, I'll consider adding it.

Thanks man!

I have found a temporary workaround that should work on all systems. This is to pass -ignore-dot-ghci to the ghci options, and then use ">" as the ghciInitial prompt.

It's definitely hacky but it works on linux and windows is all the cases I could think of.
