Crate pasta_lua 

Pasta Lua - Lua integration for Pasta DSL

This crate provides a Lua transpiler for Pasta DSL, converting Pasta AST to Lua source code. It follows the same architecture as pasta_rune but targets Lua 5.3+ instead of Rune VM.

Architecture

• LuaTranspiler: Main transpiler interface
• LuaCodeGenerator: Generates Lua code from AST nodes
• StringLiteralizer: Converts strings to optimal Lua literal format
• TranspileContext: Manages state during transpilation
• TranspilerConfig: Configuration options
• PastaLuaRuntime: Lua VM host with pasta module integration

Example

use pasta_lua::{LuaTranspiler, TranspilerConfig, PastaLuaRuntime};

let transpiler = LuaTranspiler::default();
let mut output = Vec::new();

let context = transpiler.transpile(&actors, &scenes, &mut output)?;
let lua_code = String::from_utf8(output)?;

// Create runtime with the context
let runtime = PastaLuaRuntime::new(context)?;
runtime.exec(&lua_code)?;
