Spellcheck as LSP

[vlabo]

I have been trying to make an LSP spell checker work with helix. I know a better solution is under development but until then it will be nice to have an alternative.

typos-lsp works fine but has a lot of false negatives. Unless you spend a lot of time configuring it's not very usable.

cspell works but not great.
After fallowing the steps from this blog post helix started reporting the typos but prints an error when requesting a suggestion.

in languages.toml

[[language]]
...
language-servers = ["gopls", "cspell"]
...

[language-server.cspell]
command = "node"
args = [".../packages/_server/dist/main.cjs", "--stdio"]

Can this be fixed within helix?

cspell has been proven to be a good spellchecker it will be nice if we can have it as an option.

After some investigation I managed to figure it out.
The errors are custom function that work with the vscode extension. After removing the specific function and modifying the code actions a little, it works fine now.
The configurations and custom dictionary are not supported.

Here is the fork.
