This framework contains scripts and data for building API documentation (dox) in
a standard format and style.
The Doxygen tool is used to do the actual documentation extraction and
formatting, but this framework provides a wrapper script to make generating the
documentation more convenient (including reading settings from the target
framework or other module) and a standard template for the generated
Python 3 is required to run the scripts. Additionally you
need to have the jinja2 and yaml (or pyyaml) modules.
The following command should install them for the current user:
pip install --user PyYAML jinja2
Of course, you need Doxygen!
Doxyqml and doxypypy might be needed to let doxygen document respectevely qml
To generate the dependency diagrams, you need the Graphviz Python bindings.
They are currently not available from pip, but most distributions provide them.
You can get binaries and source archives from
Unlike almost every other KDE module, kapidox does not use CMake. This is
because it is purely written in Python, and so uses distutils. While it does
not need to be installed to be used (see below), you can install kapidox with
python setup.py install
Note: For consistency, kapidox provides a CMakeLists.txt file, but this is just
a wrapper around the setup.py script.
## Writing documentation
Writing dox is beyond the scope of this documentation -- see the notes at
<https://community.kde.org/Frameworks/Frameworks_Documentation_Policy> and the [doxygen
To allow code to handle the case of being processed by kapidox a C/C++ preprocessor macro
is set as defined when run: `K_DOXYGEN` (since v5.67.0).
For backward-compatibility the definition `DOXYGEN_SHOULD_SKIP_THIS` is also set, but
its usage is deprecated.
The kapidox scripts expects certain things to be present in the directory it is
Most importantly, there should be a `README.md` file, like this page (backward
compatibility also authorize `Mainpage.dox` files). The first line of this file
is particularly important, as it will be used as the title of the documentation.
A `metainfo.yaml` file is needed for the library to be generated. It should
contain some metainformations about the library itself, its maintainers, where
A very simple example can be:
description: Library doing X
A comprehensive list of the available keys can be found on
[this page](@ref metainfo_syntax).
By default, the source of the public library must be in `src`, if the
documentation refers to any dot files, these should be in `docs/dot`.
Images should be in `docs/pics`, and snippets of example code should be in
`examples`. See the doxygen documentation for help on how to refer to these
files from the dox comments in the source files.
If you need to override any doxygen settings, put them in `docs/Doxyfile.local`.
A global settings file is defined in `src/kapidox/data/Doxyfile.global`.
## Generating the documentation
The tool for generating dox is `src/kapidox_generate`. Simply point it at the
folder you want to generate dox for (such as a framework checkout).
For example, if you have a checkout of KCoreAddons at
~/src/frameworks/kcoreaddons, you could run
and it would create a documentation in the current directory.
The folders are recursively walked through, so you can also run it on
`~/src/frameworks` or `~/src`. For a lot of libraries, the generation can last
15-30 minutes and be several hundreds of Mb, so be prepared!
Pass the --help argument to see options that control the behaviour of the
Note that on Windows, you will need to run something like
c:\python\python.exe c:\frameworks\kapidox\src\kapidox_generate c:\frameworks\kcoreaddons
## Specific to frameworks (for now)
You can ask `kgenframeworksapidox` to generate dependency diagrams for all the
frameworks. To do so, you must first generate Graphviz .dot files for all
frameworks with the `depdiagram-prepare` tool, like this:
~/src/frameworks/kapidox/src/depdiagram-prepare --all ~/src/frameworks dot
Then call `kgenframeworksapidox` with the `--depdiagram-dot-dir` option, like
~/src/frameworks/kapidox/src/kapidox_generate --depdiagram-dot-dir ../dot ~/src/frameworks
More fine-grained tools are available for dependency diagrams. You can learn
about them in [depdiagrams](@ref depdiagrams).

This project is licensed under BSD-2-Clause. But the specific theme used inside KDE
is licensed under AGPL-3.0-or-later. If you find the AGPL to restrictive you can
alternatively use the theme from [Docsy](https://github.com/google/docsy) (APACHE-2.0).
For that you need to replace the style and js script present in `src/kapidox/data/templates/base.html`.
