--- LTeX Language Server: LSP language server for LanguageTool 🔍✔️ with support for LaTeX 🎓, Markdown 📝, and others
---
--- To install, download the latest [release](https://github.com/ltex-plus/ltex-ls-plus) and ensure `ltex-ls-plus` 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 ]]
--- ```

  pandoc = 'markdown',
  plaintex = 'tex',

  tex = 'latex',
  text = 'plaintext',
