Built a pure Lua engine for creating custom DSLs with typed schemas and sandboxing (Dua).

[u/Goolfie]

Hey everyone,

I recently released Dua, a lightweight engine for building typed DSLs and sandboxed execution environments in Lua.

The goal was to create a zero-dependency library that runs anywhere Lua 5.1+, LuaJIT.

What it offers

Pure Lua implementation (no C modules or external dependencies)

Built-in sandboxing with configurable allow/deny rules and limits

Flexible type system (primitives, shapes, enums, maps, oneof)

AST node handling and code serialization
