luacheck
A static analyzer and linter for Lua code that detects undefined globals, unused variables, and other issues.
What is luacheck?
Luacheck is a static analyzer and linter for Lua that detects a wide range of coding issues, such as undefined global variables, unused variables and values, uninitialized variable access, and unreachable code. It aims to improve Lua code quality through configurable static analysis, supporting Lua versions 5.1 through 5.4 and LuaJIT. The tool is designed to be flexible and lightweight, with options for customization via command line, configuration files, or inline comments.
Lua developers and teams working on projects across multiple Lua versions (5.1-5.4 and LuaJIT) who need to enforce code quality and catch common errors early in development. It is particularly useful for those integrating linting into editors or CI/CD pipelines.
Developers choose Luacheck for its broad Lua version compatibility, high configurability for project-specific needs, and extensive editor integration. Its ability to perform parallel checking with LuaLanes offers performance advantages for large codebases.
