# Lua Obfuscator Corpus

### Dataset Summary

The Lua Obfuscator Corpus contains **26,357 Lua/Luau source files** across 17 Lua/Luau obfuscators and 1,244 unobfuscated baselines. The dataset was created to support research into Lua/Luau code obfuscation detection, obfuscator identification, and code analysis. All files have been validated using tree-sitter-lua & luau parsers to ensure syntactic validity.

## Dataset Structure

### Data Fields

- `file_name` (string): Relative path to the `.lua` or `.luau` file.
- `obfuscator` (string): Name of the obfuscator used.
- `obfuscated` (bool): Whether the file is obfuscated.
- `dialect` (string): Lua dialect (`luau`).
- `file_size` (int): File size in bytes.
- `version` (string): Obfuscator version, if applicable.
- `content` (string): Full source code contents.

### Data Splits

The dataset has no splits and all data is loaded as train split by default.

## Dataset Creation

### Source Data

Obfuscated samples were scraped from public open-source repositories or generated from a common set of unobfuscated Luau scripts using each obfuscator's CLI or web interface. Unobfuscated baselines are decompiled Roblox scripts.
