  Clang-uml – C++ to UML diagram generator based on Clang2023 · github.com · ▲79

  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.

  Hi HN! I couldn’t find a truly user-friendly PlantUML editor, so I set out to build one.

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
