history

Project history and usage

clang-uml is a Clang-based automatic diagram generator for C, C++, and Objective-C codebases, using YAML configuration to produce class, sequence, package, and include diagrams.

Project history

The public repository was created in 2021. Its README describes the project as a way to keep diagrams up to date inside a codebase and to document legacy code from real source, with output support for PlantUML, Mermaid, GraphML, and JSON.

The release series has grown from 0.1.0 through 0.6.x, with the Homebrew stable version 0.6.2 using LLVM 21 and yaml-cpp. The documentation includes a dedicated configuration reference and quick-start workflow around a .clang-uml file.

Adoption history

Distribution broadened beyond source builds: the input metadata lists Homebrew, MacPorts, Nix, and winget packaging. Homebrew ships bottles for macOS and Linux and reported 615 installs over the prior 365 days for the formula.

How it is used

A typical workflow is to run clang-uml --init, edit .clang-uml to point at a compile_commands.json database and diagram definitions, then generate PlantUML, Mermaid, GraphML, or JSON diagram output from selected source globs.

Why package nerds care

clang-uml matters to package nerds because it is a substantial LLVM consumer packaged as a cross-platform CLI: it exposes the friction points of compiler-version pinning, C++ dependency packaging, and diagram-tool integration in one formula.

Timeline

2021: GitHub repository created.
2024: 0.5.x releases expanded the maintained release train.
2025: 0.6.0, 0.6.1, and 0.6.2 releases published.
2026: Homebrew formula metadata lists 0.6.2 as stable with bottles for macOS and Linux.
