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:
