Lua Beautifier

This code formatting tool restructures Lua source code by applying consistent indentation and whitespace patterns that transform compressed or poorly formatted scripts into readable, maintainable code. The beautifier parses Lua syntax including function definitions, conditional blocks (if/then/else/end), loop constructs (for/do/end, while/do/end, repeat/until), and table definitions, applying proper indentation levels at each nesting depth.

The formatter handles Lua-specific syntax patterns common in game development including Roblox Studio scripts with Instance.new(), :GetService(), and :Connect() patterns. Love2D game framework code formats correctly alongside standard Lua modules. The algorithm preserves comments and string literals while reorganizing structural whitespace, ensuring code logic remains unchanged after formatting.

Users configure indent preferences choosing between 2 or 4 spaces, or tabs for projects requiring specific style guidelines. Sample code loading demonstrates formatting on realistic game scripts featuring nested functions, event handlers, and loop structures. Copy-to-clipboard and file download options support various development workflows. All processing occurs client-side through browser JavaScript, protecting proprietary game code without server uploads.
