:program:`clang-doc` is a tool for generating C and C++ documentation from
|
|
source code and comments.
|
|
|
|
The tool is in a very early development stage, so you might encounter bugs and
|
|
crashes. Submitting reports with information about how to reproduce the issue
|
|
to `the LLVM bugtracker <https://bugs.llvm.org/>`_ will definitely help the
|
|
project. If you have any ideas or suggestions, please to put a feature request
|
|
there.
|

|
===
|
|
|
|
:program:`clang-doc` is a `LibTooling
|
|
<https://clang.llvm.org/docs/LibTooling.html>`_-based tool, and so requires a
|
|
compile command database for your project (for an example of how to do this
|
|
see `How To Setup Tooling For LLVM
|
|
<https://clang.llvm.org/docs/HowToSetupToolingForLLVM.html>`_).
|
|
|
|
By default, the tool will run on all files listed in the given compile commands
|
|
database:
|
|
|
|
.. code-block:: console
|
|
|
|
$ clang-doc /path/to/compile_commands.json
|
|
|
|
The tool can also be used on a single file or multiple files if a build path is
|
|
passed with the ``-p`` flag.
|
|
|
|
.. code-block:: console
|
|
|
|
$ clang-doc /path/to/file.cpp -p /path/to/build
|
|
|
|
Output
|
|
======
|
|
|
|
:program:`clang-doc` produces a directory of documentation. One file is produced
|
|
for each namespace and record in the project source code, containing all
|
|
documentation (including contained functions, methods, and enums) for that item.
|
|
|
|
The top-level directory is configurable through the ``output`` flag:
|
|
|
|
.. code-block:: console
|
|
|
|
$ clang-doc -output=output/directory/ compile_commands.json
|
|
|
|
Configuration
|
|
=============
|
|
|
|
Configuration for :program:`clang-doc` is currently limited to command-line options.
|
|
In the future, it may develop the ability to use a configuration file, but no such
|
|
efforts are currently in progress.
|
|
|
