You can also open the Extensions panel in the app and search for Marko. The extension's id is marko.

Marko for Zed

Marko language support for Zed: syntax highlighting, embedded-language injections (TypeScript/CSS/SCSS), bracket matching, outline, and the Marko language server. It also registers @marko/ts-plugin so .marko imports resolve with types inside .ts/.tsx files.

The grammar is the @marko/tree-sitter parser, fetched and compiled by Zed from the [grammars.marko] entry in extension.toml.

Layout

extension.toml          # manifest: [grammars.marko] + [language_servers.marko]
Cargo.toml              # Rust/wasm extension crate
src/lib.rs              # installs @marko/language-server and launches it --stdio
languages/marko/
  config.toml           # filetype, comments, brackets
  highlights.scm        # copy of the grammar repo's queries/
  injections.scm        # copy of the grammar repo's queries/
  brackets.scm          # Zed-specific (@open/@close), maintained here
  outline.scm           # Zed-specific (@item/@name), maintained here

The language server (@marko/language-server) is installed from npm on demand into the extension's working directory and run with Zed's Node; it bundles its own TypeScript, so no project setup is required. The extension pins the major version of the server and of @marko/ts-plugin (3.x) and picks up the newest release within it once a session, since a new major may need the extension to change. For embedded highlighting, install Zed's TypeScript/CSS/SCSS languages.

Local development

To build the grammar from a local checkout instead of GitHub, point [grammars.marko] at it with a file:// URL and a committed rev (see the comment in extension.toml). Then, in Zed, run zed: install dev extension and select this directory; Zed compiles the Rust extension to wasm and builds the grammar. Open a .marko file to exercise it, and run zed --foreground from a terminal to surface grammar build, query, and language-server errors.

highlights.scm and injections.scm are copies of the grammar repo's tool-agnostic queries/; refresh them when the grammar changes:

cp ../tree-sitter/queries/*.scm languages/marko/

brackets.scm (delimiter pairs, @open/@close) and outline.scm (@item/@name) use Zed-only conventions and have no consumer outside Zed, so they live here rather than in the grammar repo.
