It uses the canonical <code>@wrnexus/syntax</code> parser, diagnostics, accessibility rules, and formatter.</p>
<pre data-language="bash"><code>bunx wrnexus-language-server --stdio</code></pre>
<p>Capabilities include syntax, accessibility and TypeScript expression diagnostics, formatting, completion, hover, document symbols, go-to-definition, references, rename, and quick fixes. The custom <code>wrnexus/virtualDocument</code> request returns the mapped TypeScript representation of an open <code>.wrn</code> document for editor TypeScript plugins and safe refactoring tools. Any LSP 3.x client can launch the stdio command. Example Neovim configuration:</p>
<pre data-language="lua"><code>vim.lsp.start(&#123;
  name = &quot;wrnexus&quot;,
  cmd = &#123; &quot;bunx&quot;, &quot;wrnexus-language-server&quot;, &quot;--stdio&quot; &#125;,
  root_dir = vim.fs.root(0, &#123; &quot;wrnexus.config.ts&quot;, &quot;package.json&quot;, &quot;.git&quot; &#125;),
&#125;)</code></pre>
<p>JetBrains users can register the same command through an LSP client/plugin. The server does not require VS Code and never reads environment secrets or sends source over a network.</p></section><section id="api" class="api"><h2>Complete TypeScript API</h2><p>Generated from the exact installed package declarations.</p><pre data-language="typescript"><code>interface WorkspaceCompletionItem &#123;
