Crate pasta_dsl 

Pasta DSL - Independent DSL parser and AST definitions.

This crate provides a standalone parser for the Pasta DSL (Domain Specific Language), enabling DSL parsing without depending on any specific backend (Lua, etc.) or runtime.

Features

• PEG-based parser: Uses Pest 2.8 for grammar-driven parsing
• Complete AST: Full AST type definitions for all Pasta DSL constructs
• Independent error types: ParseError and ParseErrorInfo for parse diagnostics
• Zero backend dependency: No Lua, registry, or runtime dependencies

Example

use pasta_dsl::parser::{parse_str, FileItem, PastaFile};

let source = "＊挨拶\n  Alice：こんにちは\n";
let ast = parse_str(source, "test.pasta").unwrap();

let scene_count = ast.items.iter()
    .filter(|i| matches!(i, FileItem::GlobalSceneScope(_)))
    .count();
println!("Parsed {} global scenes", scene_count);
