Zed

Zed is a high-performance code editor with native Sage support.

Installation

1. Open Zed
2. Press Cmd+Shift+X to open Extensions
3. Search for “Sage”
4. Click Install

Alternatively, use the command palette (Cmd+Shift+P) and run “zed: install extension”.

Features

The Sage extension for Zed provides:

• Tree-sitter Highlighting — Fast, accurate syntax highlighting
• LSP Diagnostics — Real-time error reporting from the Sage compiler
• Auto-indentation — Smart indentation for agents, functions, and blocks

Requirements

The language server requires sage to be on your PATH. Install via:

# Homebrew (macOS)
brew install sagelang/sage/sage

# Cargo
cargo install sage-lang

# Quick install
curl -fsSL https://raw.githubusercontent.com/sagelang/sage/main/scripts/install.sh | bash

Troubleshooting

No syntax highlighting

If syntax highlighting isn’t working:

1. Ensure the file has a .sg extension
2. Check that the Sage extension is installed (Extensions → Installed)
3. Try restarting Zed

No diagnostics

If you’re not seeing error diagnostics:

1. Verify sage is on your PATH: which sage
2. Check Zed logs: Cmd+Shift+P → “zed: open log”
3. Look for “sage-sense” or “language server” errors

Extension not loading

If the extension fails to load:

1. Uninstall the extension
2. Restart Zed
3. Reinstall the extension
