Sure,

Enter or neovim home, something like below and download this gist, it is important to create the files where the actions will save exceptions and dict words!, remember to modify the gist to your language.

In your config.lua / init.vim load it after loading nvim-lspconfig...
require('ltex') or silent luafile ~/$NVIM_HOME/lua/ltex.lua

Please, remember to change $NVIM_HOME to your path, I define a global one in my shell startup, maybe you need to change it to fit your needs.

Made every step but had en error Error detected while processing /home/user/.config/nvim/init.vim

What I did wrong? ltex-ls is executable and located in PATH...

Is it support multiple languages?

yes, it supports, if you define them in the file I use normally with english / portuguese / french, remember to change language with will be checking, you have to generate a configuration changed request with LSP.

I really don't know

Is your global $NVIM_HOME ="/home/user/.config/nvim" ?

No, but yours can be. I define it

Ok :)

I used this file instead of yours from your guide and now nvim works without errors, but lsp-server still not starting. LspInfo says: filetype: No filetypes defined, please define filetypes in setup().
Where I should to define filetypes, can you share the example?

My init.vim code for your lsp is:

lua << EOF
require('ltex')
EOF

the mentioned file is my PR which still a WIP
try this:

let g:tex_flavor = "latex"
silent! au FileType tex\
                silent luafile ~/.config/nvim/lua/ltex.lua

you can use vim.fn.stdpath "config" to get neovim's config directory

thanks! I'm working in a new version btw Em sex., 26 de nov. de 2021 às 15:14, MurdeRM3L0DY ***@***.***> escreveu:

I'm trying to disable a few rules in my config. Could you share what the content of spell/disable.txt looks like? I tried to create a file with the following content to disable English spelling:

MORFOLOGIK_RULE_EN

I got it working. The problem is on my side, as I forgot the settings key and was only using ltex.

Hello there!
I've made a plugin to support code actions (and some extras) in neovim with native LSP.

Handle dictionaries, false positives, and hidden rules in external files like the vscode-ltex plugin. The files are compatible between these plugins (same naming and content).

In the repository I drop some demos: barreiroleo/ltex_extra.nvim. Better name suggestions are welcome.

Thanks in advance to the people who want to try it and give me their opinion. Thanks also @lbiaggi for some ideas that i took from you.

A minimal script to implement _ltex.addToDictionary:
