Enhance Zed with Solidity language support, including syntax highlighting and language server features such as diagnostics and more!

• Syntax highlighting via tree-sitter-solidity
• Diagnostics, completions, go-to-definition, and other LSP features via @nomicfoundation/solidity-language-server
• Code outline, indentation, and bracket matching

• Syntax highlighting via tree-sitter-yul, including recognition of EVM builtins
• Code outline, indentation, and bracket matching
• No LSP support (the Nomic Foundation language server does not support standalone .yul files)

Example tasks for different test frameworks can be found in .zed/tasks.json.

How to set up Foundry to run tests via a runnable (the play button next to tests in the UI) and via keyboard shortcut.

Example task that connect with the definitions in runnables.scm via tags.

[
  // Individual test.
  {
    "label": "forge test: $ZED_SYMBOL",
    "command": "forge",
    "args": ["test", "--match-test", "$ZED_SYMBOL", "-vvvvv"],
    "tags": ["solidity-test"],
    "reveal": "always",
    "use_new_terminal": false
  },
  // Contract test.
  {
    "label": "forge test: $ZED_SYMBOL (contract)",
    "command": "forge",
    "args": ["test", "--match-contract", "$ZED_SYMBOL", "-vvvvv"],
    "tags": ["solidity-contract-test"],
    "reveal": "always",
    "use_new_terminal": false
  }
]

Example keymap to run Forge test for the symbol under the cursor.

[
  {
    "context": "Editor && extension==sol",
    "bindings": {
      "alt-g": ["task::Spawn", { "task_name": "forge test: $ZED_SYMBOL" }]
    }
  }
]
