![]() Generate an index file (useful for big projects). Include source code in the documentation. Show directory hierarchies in documentation. Show all class members even if they aren’t documented. Output a detail description at the top of the documentation. Treat multiline comment blocks as a brief description. These are some settings that I like to use to generate as much documentation as possible. DOT_PATH = path/to/dot Optional Changes to Configuration File – More Documentation Specify the path to DOT if it isn’t on your system $PATH. Show call graphs even if there isn’t documentation for the functions. This didn’t work well for me - it generated graphs for class hierarchy but did not generate function call graphs (too bad). INPUT_FILTER = "python /path/to/doxypy.py"įILTER_SOURCE_FILES = YES Optional Changes to Configuration File – Generating Call Graph Imagesĭoxygen can generate call graph images in the documentation if you have the DOT tool installed (part of GraphViz). Make sure doxypy.py is executable and that you are using it with a fairly new version of Python (2.3 or higher) because it uses the enumerate() built-in function. Pythfilter by Matthias Baas (2003) – converts Python to C++ stubs, no longer works now that Doxygen supports Pythonĭoxypy by foosel and demod (2006) – converts Python docstrings to Doxygen special documentation blocks, allowing you to use Doxygen/Javadoc syntax ![]() Optional Changes to Configuration File – Adding a Filter RECURSIVE = YES if the python files are in sub-directories. OUTPUT_DIRECTORY = Where the doxygen output filesįILE_PATTERNS = *.py if you want to only generate These are the settings that are required to change to run Doxygen on python source code. I still have no idea what some of the options do. The configuration file can be overwhelming. Or to generate an example configuration file without any comments doxygen -s -g config.dox Required Changes to Configuration File Use the -g option to generate an example configuration file to get started. Generate a Template Doxygen Configuration Fileĭoxygen is very simple to use, once you have the configuration file set up properly. Download doxypy python filter (not necessary, but adds full support for embedding special syntax to comments).Download and install the latest version of GraphViz (not necessary, for creating call graphs).Download and install the latest version of Doxygen.There’s lots of other tools available for auto-documenting Python code. This is a guide for automatically generating documentation off of Python source code using Doxygen.īut don’t take my word for it. I was elated to find out that they’ve included Python support in Doxygen without having to translating Python to C++. Python comes with a tool for generating documentation called Pydoc, but I don’t like tools that use introspection because they usually choke on weird file import rules. It was written for C/C++ but there are hacks/filters for getting it working with other languages like Python, Perl and Verilog. Doxygen is easily one of the best programs. Whenever documentation exists in a seperate file it always seems to drift away from the code.Ī while back I compared several open source tools for automatically generating documentation based on code comments. When someone else is trying to modify your code they have no idea they need to read a PDF API document to find out more information about what a function is supposed to do. I strongly believe that code and documentation should always go hand in hand. ![]() All programming is maintenance programming, meaning that the most value comes from programming code that can be picked up and maintained by someone else.
