proselint VS textidote

So cool. Looks like the proseline site is down. For anyone else who wanted to read the approach - https://github.com/amperser/proselint/blob/b5b7536bec5fd461e...

You can try proselint, which also has built-in support in null-ls. Its LaTeX support isn't perfect, but it's workable.

Something like grammar-guard, proselint and/or language-tool?

Yep, though there's not a lot to see! Follow the instructions for installing proselint at https://github.com/amperser/proselint and configure as follows:

Vale uses a customizable grammar checker, and you can download some open-source configurations to start working with from the link above. Then, you just need to add something like below to your Emacs configuration: (flycheck-define-checker vale "A prose linter" :command ("vale" "--output" "line" source) :standard-input nil :error-patterns ((error line-start (file-name) ":" line ":" column ":" (id (one-or-more (not (any ":")))) ":" (message) line-end)) :modes (markdown-mode org-mode text-mode) ) (add-to-list 'flycheck-checkers 'vale 'append) (setq flycheck-vale-executable "/usr/local/bin/vale") It looks like you can do something similar with Proselint, which looks wonderful and I have been meaning to try using in my day-to-day: https://unconj.ca/blog/linting-prose-in-emacs.html .

proselint

Full list here. Since the tool is a linter, it sounds like it should work with language servers. I use CoC.nvim for LSP features. Thankfully some smart guys have figured out how to make proselint work with coc.nvim & coc-diagnostic (see here). Now it works for my blog posts just like clangd does for my C++ code.

You're looking for proselint. https://github.com/amperser/proselint

Otherwise you can have a look at TeXtidote, although I'm not sure whether it can be used as a null-ls source or if it only works as a stand-alone program.

Hm, I can't reproduce the error. If I download the latest release https://github.com/sylvainhalle/textidote/releases/tag/v0.8.3 and run java -jar textidote.jar example.tex (with example.tex from the GitHub repository) the output is different from the output of java -jar textidote.jar --check en example.tex. In particular, the second command reports tex to be a spelling error and gives a ridiculous amount suggested spellings.

Textidote is also based on languageTool. It doesn't use LSP, but it can generate nice browseable HTML to look at all of the errors. It's not emacs-specific, but there's a snippet in the README of how to integrate it with flycheck.

Check out textidote too. It's languagetool understanding \LaTeX syntax, and you can set it for flycheck-checker. Emacs-langtool coupled with langtool-ignore-fonts is also good for \LaTeX documents. You may want to configure them to disable a few rules to reduce false positives.

I really like Textidote. It does spell and grammar checking: https://github.com/sylvainhalle/textidote
