Arduino for Zed

Arduino language support for Zed, with syntax highlighting and arduino-language-server integration.

Features

  • Dedicated Arduino language for .ino files (instead of C++)
  • Syntax highlighting via tree-sitter-arduino
  • Code outline, bracket matching, indentation, and text objects
  • Auto-download of arduino-language-server and arduino-cli

Requirements

The language server requires clangd installed on your system:

  • macOS: brew install llvm
  • Ubuntu/Debian: sudo apt install clangd
  • Arch: sudo pacman -S clang
  • Fedora: sudo dnf install clang-tools-extra

Configuration

To get full LSP support (diagnostics, autocomplete, go-to-definition), set your board's FQBN in .zed/settings.json:

{
  "lsp": {
    "arduino-language-server": {
      "binary": {
        "arguments": ["-fqbn", "arduino:avr:uno"]
      }
    }
  }
}

Replace arduino:avr:uno with your board. Run arduino-cli board listall to find available FQBNs.
