ProcForge

semester project, growing

A modular Rust implementation of Object-Process Methodology (OPM, ISO 19450) with Petri-net simulation. Started as a FJFI ČVUT semester project — largely because I didn't want to hand-draw OPM diagrams for the coursework — it's built as a lightweight, simulatable alternative to OPCloud, the canonical (but finicky, Chrome-only) OPM tool. The goal is to grow it into an open-source OPM tool if grant funding comes through; that decision is still pending.

Features

• OPL parser (Dori-style syntax, pest grammar)
• Auto-layout via Graphviz dot
• SVG renderer with token visualization, plus GIF export
• Petri-net simulation — single-step and run, with a seeded RNG
• Desktop UI (egui/eframe) with live reload of the diagram on OPL edit
• Hierarchical OPDs (zooming into a process)
• Web (WASM) frontend — currently a stub

Architecture

A workspace of four crates: opm-core (the only crate with business logic — model, parser, layout, render, Petri-net engine, export) plus three thin frontends: opm-cli, opm-desktop, and opm-web.
