## Usage
Configure `vimdoc-language-server` in your editor of choice, for example with

[nvim-lspconfig](https://github.com/neovim/nvim-lspconfig):
```lua
vim.lsp.enable('vimdoc_ls')

### CLI
The server also provides standalone CLI subcommands that work without an editor.
**Format** vimdoc files (in-place or check-only for CI):
```sh
vimdoc-language-server format doc/
vimdoc-language-server format --check doc/*.txt
vimdoc-language-server --line-width 80 format doc/
```
**Check** for diagnostics (duplicate tags, unresolved taglinks):
```sh
vimdoc-language-server check doc/
vimdoc-language-server check --ignore unresolved-tag doc/
```
