Convert C++ header files to PlantUML

Project description

hpp2plantuml - Convert C++ header files to PlantUML

.. _sec-intro:


The purpose of this tool is to convert C++ header files to a UML representation
in `PlantUML <>`_ syntax that can be used to generate diagrams with PlantUML.

`PlantUML <>`_ is a program rendering UML diagrams from plain text inputs using an
expressive language.

This package generates the text input to PlantUML from C++ header files. Its
ambition is limited but it should produce reasonable conversion for simple class
hierarchies. It aims at supporting:

- class members with properties (``private``, ``method``, ``protected``), methods with
basic qualifiers (``static``, abstract),

- inheritance relationships,

- aggregation relationships (very basic support).

The package relies on the `CppHeaderParser <>`_ package for parsing of C++ header

.. _sec-module-usage:


The ``hpp2plantuml`` package can be used from the command line or as a module in
other applications.

Command line

The command line usage is (``hpp2plantuml --help``):


usage: hpp2plantuml [-h] [-o FILE] -i HEADER-FILE

hpp2plantuml tool.

optional arguments:
-h, --help show this help message and exit
-o FILE, --output-file FILE
Output file
-i HEADER-FILE, --input-file HEADER-FILE
Input file (must be quoted when using wildcards)

Input files are added using the ``-i`` option. Inputs can be full file paths or
include wildcards. Note that double quotes are required when using wildcards.
The output file is selected with the ``-o`` option. The output is a text file
following the PlantUML syntax.

For instance, the following command will generate an input file for PlantUML
(``output.puml``) from several header files.

.. code:: sh
:name: usage-sh

hpp2plantuml -i File_1.hpp -i "include/Helper_*.hpp" -o output.puml


To use as a module, simply ``import hpp2plantuml``. The ``CreatePlantUMLFile``
function can then be used to create a PlantUML file from a set of input files.
Alternatively, the ``Diagram`` object can be used directly to build internal
objects (from files or strings). The ``Diagram.render()`` method can be used to
produce a string output instead of writing to a text file.

.. _sec-module-install:


Using ``pip``

The package is available on `PyPi <>`_ and can be installed using pip:


pip install hpp2plantuml

>From source

The code uses ``setuptools``, so it can be built using:


python install

To build the documentation, run:


python sphinx

To run the tests, run:


python test

The full documentation is available via:

- `This org-mode post <>`_
