The DOTNUMTHREADS specifies the number of dot invocations doxygen is allowed to run in parallel. This would help Doxygen to run DOT for graphs and 2nd option is to consideration is. I checked the logfile of Doxygen and found exactly 4 entries like this: Generating caller graph for function įor every other class there is only the Generating docs for compound. Change it to the dot path location as I did for windows as: DOTPATH 'C:/Program Files/Graphviz2.30/bin'. The DOTIMAGEFORMAT tag can be used to set the image format of the images generated. Among the dot options, use DOTIMAGEFORMAT also. If you have the 'dot' tool in the path, you can set HAVEDOT to YES in the configuration file to let doxygen use it. But the result is still the same: For 4 methods a called/caller graph is generated but not for the other methods. Doxygen can use the 'dot' tool from graphviz to generate more advanced diagrams and graphs. Now, I want/need the caller/called graphs in there and I set every flag that could have something to do with it to 'YES'. ![]() I configured Doxygen to scan a bigger project and generate the documentation as HTML page. I'm using Doxygen 1.8.7 and Graphviz 2.38. Even in this simple example, you can see how a zoomed-out view allows you to understand the complex structure.This seems to be a bug. The top right shows a close-up view of a tiny section of the picture. To test this out for a blog post, I downloaded the source code to Azureus, a large Java-based project. Now, generate documentation with this command: Here are all the changes I made to this file. Edit this to allow recursive searching, to look for java source, to generate call graphs and to generate pictures, and to generate UML style diagrams. Now you have a config file called Doxyfile. ![]() Then, run doxygen to generate a config file. Here are the steps involved in generating UML diagrams.įirst, you install doxygen (to parse the files) and graphviz (to write out PNG of graphs) While its diagrams might not be perfect, they were very helpful for C++ projects in the past. It works on C,C++, and Java, among many other languages. Looking on Google didn't produce anything obvious: people pointed to eUML2, which was difficult to install, and some tools didn't generate UML from existing code.Īfter a while of searching, I remembered the Doxygen utility which writes documentation from source code. I was navigating through a large Java project today, and I needed some source tools to help me visualize the massive class hierarchy. ![]()
