basilisk-zed

English · 简体中文

Zed editor extension for Basilisk — WASM-based Python type checking and language server integration.

Role in Basilisk

This is the Zed editor integration. It is a native Zed extension compiled to WASM that connects the Basilisk language server to Zed, providing real-time diagnostics, hover, go-to-definition, code actions, and debugging via DAP.

Key concepts

• WASM extension — compiled as a cdylib crate targeting wasm32-wasip1, loaded natively by Zed.
• zed_extension_api — uses Zed's official extension API for language server lifecycle management.
• basilisk-common — shares diagnostic codes and constants with the rest of the Basilisk workspace (also WASM-compatible).
• Tree-sitter grammars — provides Python syntax highlighting via tree-sitter.
• DAP debugging — supports the Debug Adapter Protocol for integrated Python debugging.
