LTeX Language Server: LSP language server for LanguageTool 🔍✔️ with support for LaTeX 🎓, Markdown 📝, and others

To install, download the latest [release](https://github.com/valentjn/ltex-ls/releases) and ensure `ltex-ls` is on your path.

This server accepts configuration via the `settings` key.

```lua
  settings = {
		ltex = {
			language = "en-GB",
		},
	},
```

To support org files or R sweave, users can define a custom filetype autocommand (or use a plugin which defines these filetypes):

```lua
vim.cmd [[ autocmd BufRead,BufNewFile *.org set filetype=org ]]
```
]=],
  },
}
