🧹 Nitpick comments (3)
packages/lua/README.md (1)
1-24: Documentation covers essential information.The README provides clear installation instructions and a practical usage example, which should help users get started quickly with the Lua language support.
Consider adding a brief introduction about what features this package provides and how it integrates with the broader ast-grep ecosystem.
packages/lua/nursery.js (1)
1-16: Test harness validates basic functionality.The test setup correctly configures the nursery environment for Lua and includes a basic verification that the parser can identify a simple function call.
Consider adding more test cases to verify parsing of different Lua language constructs such as tables, functions, loops, and conditionals to ensure comprehensive coverage.
packages/lua/package.json (1)
1-47: Package configuration needs some improvements.The package configuration is mostly complete, but there are several important fields missing:
- The
descriptionfield is empty (line 4)- The
authorfield is empty (line 22)- No
repositoryfield to link to the GitHub repository- No
bugsorhomepagefields to provide support informationI suggest adding these missing fields to improve package metadata:
{ "name": "@ast-grep/lang-lua", "version": "0.0.1", - "description": "", + "description": "Lua language support for ast-grep", "main": "index.js", "scripts": { "build": "tree-sitter build -o parser.so", "source": "node nursery.js source", "prepublishOnly": "node nursery.js source", "postinstall": "node postinstall.js", "test": "node nursery.js test" }, "files": [ "index.js", "index.d.ts", "type.d.ts", "postinstall.js", "src", "prebuilds" ], "keywords": ["ast-grep"], - "author": "", + "author": "NatoBoram", "license": "ISC", + "repository": { + "type": "git", + "url": "https://github.com/ast-grep/ast-grep.git", + "directory": "packages/lua" + }, + "homepage": "https://github.com/ast-grep/ast-grep/tree/main/packages/lua#readme", + "bugs": { + "url": "https://github.com/ast-grep/ast-grep/issues" + }, "dependencies": { "@ast-grep/setup-lang": "0.0.3" },

🔇 Additional comments (3)
packages/lua/postinstall.js (1)
1-4: Implementation follows standard postinstall pattern.The postinstall script follows the expected pattern for language support in ast-grep, properly invoking the setup function with the current directory.
packages/lua/index.d.ts (1)
1-10:✅ Verification successful
Type definition is well-structured.
The
LanguageRegistrationtype properly defines the interface for the Lua language support with appropriate optional fields. This aligns well with the ast-grep type system.
🏁 Script executed:
#!/bin/bash # Check if there's a corresponding index.js file that implements this interface if [ -f "packages/lua/index.js" ]; then echo "index.js exists, showing its contents:" cat "packages/lua/index.js" else echo "index.js does not exist, which is unexpected since it's imported in nursery.js" exit 1 fiLength of output: 359
Interface & Implementation Verification Passed
TheLanguageRegistrationtype inpackages/lua/index.d.tsis well-structured and accurately captures the interface expected for Lua language support. The corresponding implementation inpackages/lua/index.jsprovides the required fields—libraryPath,extensions,languageSymbol, andexpandoChar—which confirms consistency between the type definition and its usage. The exclusion of the optionalmetaVarCharfield in the implementation is acceptable.packages/lua/index.js (1)
1-9: LGTM! This implementation properly exports the Lua language configuration.The code is clean and follows the expected pattern for language support in ast-grep. It correctly:
- Builds the path to the parser.so file
- Exports the necessary properties for Lua language integration
- Specifies the .lua extension and correct language symbol
