Editor-neutral Language Server Protocol support for .wrn files. It uses the canonical @wrnexus/syntax parser, diagnostics, accessibility rules, and formatter.

bunx wrnexus-language-server --stdio

Capabilities include syntax, accessibility and TypeScript expression diagnostics, formatting, completion, hover, document symbols, go-to-definition, references, rename, and quick fixes. The custom wrnexus/virtualDocument request returns the mapped TypeScript representation of an open .wrn document for editor TypeScript plugins and safe refactoring tools. Any LSP 3.x client can launch the stdio command. Example Neovim configuration:

vim.lsp.start({
  name = "wrnexus",
  cmd = { "bunx", "wrnexus-language-server", "--stdio" },
  root_dir = vim.fs.root(0, { "wrnexus.config.ts", "package.json", ".git" }),
})

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.
