4.10 Generating MySQL Doxygen Documentation Content

The MySQL source code contains internal documentation written using Doxygen. The generated Doxygen content is available at https://dev.mysql.com/doc/index-other.html. It is also possible to generate this content locally from a MySQL source distribution using the following procedure:

1. Install doxygen 1.9.2 or later. Distributions are available here at http://www.doxygen.nl/.

   After installing doxygen, verify the version number:

   $> doxygen --version
   1.9.2

2. Install PlantUML.

   When you install PlantUML on Windows (tested on Windows 10), you must run it at least once as administrator so it creates the registry keys. Open an administrator console and run this command:

   $> java -jar path-to-plantuml.jar

   The command should open a GUI window and return no errors on the console.

3. Set the PLANTUML_JAR_PATH environment to the location where you installed PlantUML. For example:

   $> export PLANTUML_JAR_PATH=path-to-plantuml.jar

4. Install the Graphviz dot command.

   After installing Graphviz, verify dot availability. For example:

   $> which dot
   /usr/bin/dot
   $> dot -V
   dot - graphviz version 2.40.1 (20161225.0304)

5. Change location to the top-level directory of your MySQL source distribution and do the following:

   First, execute cmake:

   $> cd mysql-source-directory
   $> mkdir build
   $> cd build
   $> cmake ..

   Next, generate the doxygen documentation:

   $> make doxygen

   Inspect the error log, which is available in the doxyerror.log file in the top-level directory. Assuming that the build executed successfully, view the generated output using a browser. For example:

   $> firefox doxygen/html/index.html
