Following -Werror from cabal file

[fkrunic]

Your environment

Which OS do you use?

• macOS Monterey (12.6.6)

Which version of GHC do you use and how did you install it?

• 9.2.7 from ghcup

How is your project built (alternative: link to the project)?

• Cabal 3.2.6.0

Which LSP client (editor/plugin) do you use?

• Neovim + HLS via lsp-zero.

Which version of HLS do you use and how did you install it?

• 1.10.0.0 from ghcup

Have you configured HLS in any way (especially: a hie.yaml file)?

• No

What's wrong?

The following options are specified under the ghc-options section of my cabal file:

• -Wall
• -Werror=missing-fields
• -Werror=incomplete-patterns

How do I pass these options into HLS so that instead of highlighting missing fields or incomplete patterns as warnings in Neovim, it highlights them as build errors to match the behavior of cabal build?

Debug Information

LSP configuration in after/plugin/lsp_config.lua:

local lsp = require('lsp-zero')

lsp.preset('recommended')
lsp.ensure_installed({
  'lua_ls',
  'hls'
})

-- Fix for undefined 'vim'
lsp.nvim_workspace()
lsp.setup()

vim.diagnostic.config({
  virtual_text = false
})

We do get the flags from the cabal file. I believe the issue here is that we explicitly disable -Werror after all that, so that we don't block compilation for warnings.

There is some discussion in #853, probably continue there?

Sounds good, thank you!
