Hi, clang-uml is an open-source C++ to UML diagram generator, driven by YAML configuration files. The main idea behind the project is to easily maintain up-to-date diagrams within a code-base or document legacy code. The configuration file for clang-uml defines the types and contents of each generated diagram. The diagrams can be currently generated in PlantUML and JSON formats. Main features: - class, sequence, package and include diagrams - up to C++17 with support for C++20 concepts - visualization of template specialization relationships - declarative diagram content filtering based on…

Hi HN, UML diagrams were meant to standardise system design, but they’ve become outdated — slow to build, hard to change, and rarely used in practice. Most tools feel clunky, and diagrams often go stale fast. I’m building RapidChart, a tool to bring diagramming back to life — fast, flexible, and developer-first. What makes it different: Cursor-style interface for rapid diagram creation Fully customisable and exportable AI-assisted (works with GPT-4, Claude, etc.) 100% free This began as part of my research at Imperial College London, and I’d really value your feedback. Here’s the link:…

Hi HN! I couldn’t find a truly user-friendly PlantUML editor, so I set out to build one. PlantDiagrams lets you describe a diagram in plain English; it generates the PlantUML and renders it instantly. The goal is to shorten the path from idea → diagram without fighting the editor. Tech: - Next.js / Supabase / FLy.io / Vercel Highlights - Natural-language to PlantUML with live preview - Export diagrams (SVG/PNG/TXT) - Organize work with Projects - Share via link; optional comments for review - Sample gallery to open and tweak examples Try it:…

I've been exploring the (not so=) amazing potential of AI in coding and have compiled a list of tools. From AI-powered IDEs to code generators, this resource is my contribution to the community. I'm still on the fence about including txt2sql projects, as their functionality seems too basic to me. And I'm personally maintaining this, so your feedback is wellcome.
