hdoc: the modern documentation tool for C++
See hdoc.io for more details. Usage documentation is hosted at hdoc.io/docs.
An important notice about this repository
The contents of this repository are a subset of a private repository where hdoc's development takes place.
Overview and features
- Autogenerated API documentation. hdoc generated API documentation for every function, record, enum, and namespace in your codebase.
- Integrated Markdown pages. hdoc converts your Markdown pages into a website and puts it next to your API docs. All of your documentation is in one place.
- Instant codebase search. Instant search-as-you-type lookup of symbols throughout your entire codebase.
- Easy CI integration. Your documentation is never out of date if you build it with your code. All you need to do is add hdoc to your build job.
- Advanced C++ parser. hdoc understands the newest C++ features with its advanced LLVM/Clang-based parser.
- Clean, fast output. hdoc outputs fully static HTML with no required Javascript, ensuring your users never have to wait.
Quick start
Linux
hdoc depends on LLVM/Clang and OpenSSL, and all other dependencies are vendored in subprojects/
.
hdoc also comes with a Nix Flake which sets up a development environment for you with all of the needed dependencies, and should work on all Linux distributions.
Follow the instructions below to build hdoc.
# Build hdoc
meson build # Configure the build directory
ninja -C build # Compile hdoc binaries and tests
./build/hdoc --verbose # Run hdoc over itself, saving the HTML documentation to ./hdoc-output/
More instructions for using hdoc can be found at hdoc.io/docs.
Windows (Unofficial Support)
Windows support for hdoc is unofficial and was contributed by @yqs112358. Windows is unofficially supported as the hdoc team does not use it for development. hdoc is not tested on Windows and no guarantee is made for its functionality there. However, the following instructions for compiling hdoc on Windows.
MSYS2
and MinGW-w64-x86_64-gcc
must be installed in order to compile hdoc on Windows.
Once the prerequisites have been installed, follow the instructions below to build hdoc:
# Install dependent packages for MinGW
pacman -S groff
pacman -S unzip
pacman -S mingw-w64-x86_64-meson
pacman -S mingw-w64-x86_64-cmake
pacman -S mingw-w64-x86_64-clang
pacman -S mingw-w64-x86_64-clang-analyzer
pacman -S mingw-w64-x86_64-clang-tools-extra
# Set PATH
export PATH=/mingw64/bin:/mingw64/lib:$PATH # You can also add this line into ~/.bashrc
# Build hdoc
meson build # Configure the build directory
ninja -C build # Compile hdoc binaries and tests
./build/hdoc --verbose # Run hdoc over itself, saving the HTML documentation to ./hdoc-output/
Reportedly, hdoc-client.exe
does not currently work on Windows due to a linking problem.
However, hdoc.exe
should work.
Running tests
hdoc has a suite of unit and integration tests, which can be run using the instructions below.
# Assumes you've already built hdoc
cd build
# Running indexing tests and unit tests
./index-tests
./unit-tests
# Running integration tests
cd ../tests/integration_tests
./clone_test_repos.sh # Pull testing repos from GitHub
./test.sh # Run hdoc over testing repos
