Styx Extension for Zed

Syntax highlighting and language support for the Styx configuration language in Zed.

Features

  • Syntax highlighting via tree-sitter
  • Bracket matching and auto-closing
  • Automatic indentation
  • Language injection in heredocs (e.g., SQL, JSON, HTML)

Installation

From Zed Extensions (Recommended)

  1. Open Zed
  2. Open the Extensions panel (cmd+shift+x or View > Extensions)
  3. Search for "Styx"
  4. Click Install

Manual Installation

# Clone the repository
git clone https://github.com/bearcove/styx
cd styx/editors/zed-styx

# Copy to Zed extensions directory
mkdir -p ~/.config/zed/extensions/installed/styx
cp -r . ~/.config/zed/extensions/installed/styx/

Heredoc Language Injection

Styx supports heredocs with language hints for syntax highlighting:

query <<SQL,sql
SELECT * FROM users
WHERE active = true
SQL

template <<HTML,html
<div class="container">
  <h1>Hello, World!</h1>
</div>
HTML

The language after the comma (e.g., sql, html) triggers syntax highlighting for that language within the heredoc content.

Development

To work on the extension locally:

# Link the extension for development
ln -s $(pwd)/editors/zed-styx ~/.config/zed/extensions/installed/styx

# After making changes to the tree-sitter grammar:
cd crates/tree-sitter-styx
npx tree-sitter generate

# Restart Zed to pick up changes
