This is an extension for the Zed editor, providing support for the Nix language.

nix-zed can be installed through Zed's extension manager. To do so, open the command palette (Ctrl+Shift+P) in Zed and type zed: extensions. From there, you can search for the Nix language extension and install it.

• Syntax highlighting
• Code completion (brackets, etc.)
• Language server integration (nixd)
• Language server configurability (choosing another Nix LSP, such as nil)
• Inlay hints (such as package versions)
• Intelligent hinting when "nixd" is unavailable
• JSON highlighting for flake.lock files

Contributions are welcome! If you have any ideas or suggestions, feel free to open an issue or a pull request.

To develop on this extension, you can follow the upstream guide for authoring extensions.

On NixOS, if you want to use developer extensions in Zed, you'll need to patch the interpreter for the WASM toolchain installed by Zed:

patchelf --set-interpreter /run/current-system/sw/bin/ld.so $HOME/.local/share/zed/extensions/build/wasi-sdk/bin/wasm-ld
patchelf --set-interpreter /run/current-system/sw/bin/ld.so $HOME/.local/share/zed/extensions/build/wasi-sdk/bin/clang

There is a predecessor to this project, zed-nix. Unfortunately, it seems to not be actively maintained anymore.
