Luacheck is a linter and static analyzer for Lua code, detecting issues like undefined globals, unused variables, and unreachable code. It is written in Lua, supports Lua 5.1-5.3 and LuaJIT syntax, and offers extensive configuration via CLI flags, config files, and inline comments.

Use cases

• lint lua code for unused variables
• detect undefined global variables in lua project
• static analysis of lua 5.3 codebase
• check luajit scripts for unreachable code
• configure custom globals for lua project linting
• run lua linter in ci pipeline

When to choose

• you maintain a Lua or LuaJIT codebase and want automated code quality checks
• you need configurable linting with project-specific globals and warning filters
• you want a lightweight CLI linter installable via LuaRocks

When to avoid

• you need linting for languages other than Lua
• you require an actively developed tool with frequent updates
• you need an IDE-integrated formatter rather than a standalone linter
