Adhering to Standard Lua Coding Conventions

Lua scripts rely heavily on clean block scopes (function, do, if ... then, repeat ... until) and structured tables. Standardizing syntax improves collaboration, reduces runtime errors from mismatched end statements, and maintains clean architecture across game scripting platforms like Roblox, Neovim configurations, and embedded applications.

Consistent Block Nesting

Proper indentation levels for conditional statements and loops prevent logic blind spots and make debugging deeply nested callbacks significantly easier.

Table & Metatable Alignment

Cleanly formatted multi-line tables and object orientation structures (using __index) keep object definitions readable and organized.

Frequently Asked Questions

Does this Lua formatter support Roblox Luau syntax?

Yes. It handles standard Lua 5.1/5.2/5.3 constructs as well as Luau syntax extensions commonly used in game development environments.

Is my source code sent to a remote server?

No. All formatting logic runs entirely within your browser using client-side lexical tokenization. Zero code or telemetry is transmitted across the network.
