Possibility to disable rules on a per-mode basis

[dschrempf]

For example, the WHITESPACE_RULE is useful many times, but not in a Git commit buffer.

Maybe try tweak these variables:

lsp-ltex/lsp-ltex.el

Lines 95 to 105 in 84d9cd8

	(defcustom lsp-ltex-disabled-rules '()
	"Lists of rules that should be disabled (if enabled by default by
	LanguageTool)."
	:type 'list
	:group 'lsp-ltex)
	(defcustom lsp-ltex-enabled-rules '()
	"Lists of rules that should be enabled (if disabled by default by
	LanguageTool)."
	:type 'list
	:group 'lsp-ltex)

Thanks. I was assuming these are global variables. I mean we could set them buffer-locally when entering the respective text-based mode.

It would be nice to have this feature available from the LSP action. That is, disable this rule for this major mode.

I tried doing the following:

(add-hook 'git-commit-mode-hook
            (lambda () (set (make-local-variable 'lsp-ltex-disabled-rules)
                            '(:en-US ("WHITESPACE_RULE")))))

But that doesn't really work, I think because lsp-ltex--combined-disabled-rules is not updated accordingly.

Also, I would actually like to disable this rule for all languages 😄, another complication.

Yeah, you are right. I haven't looked at the code for a long time, so it will take me some time to rework this. 🤔

BTW, PRs are always welcome!
