Orrery Parser

Parser for the Orrery diagram language. This crate provides the complete parsing pipeline from source text to semantic diagram representation.

Overview

The parser processes Orrery source code through a multi-stage pipeline:

1. Resolve — Recursively load the root file and all its imports via a SourceProvider, building a virtual address space and populating the import tree. For each file:
   • Tokenize — Convert source text to tokens
   • Parse — Build an AST from tokens
2. Desugar — Normalize syntax sugar and flatten imported types
3. Validate — Check semantic validity
4. Elaborate — Transform to the semantic model (orrery_core::semantic::Diagram)

Quick Example

use std::path::Path;
use orrery_parser::{parse, ElaborateConfig, InMemorySourceProvider, error::ParseError};

fn main() -> Result<(), ParseError> {
    let source = r#"
        diagram component;
        user: Rectangle;
        server: Rectangle;
        user -> server: "Request";
    "#;

    let mut provider = InMemorySourceProvider::new();
    provider.add_file("main.orr", source);

    let diagram = parse(Path::new("main.orr"), provider, ElaborateConfig::default())?;
    println!("Diagram kind: {:?}", diagram.kind());
    Ok(())
}
