Question

I wonder if it’s possible to use a shell command output as an option parameter in Doxygen config file. For example, you need to set ‘PROJECT_NAME’ option. I already have a README file and the first line of this file is the name of the project. I could do ‘head -1 ../README‘ in Doxygen config instead of copying the same few words all over the place. Is it possible?

Answer 1

You can use $(PROJECT_NAME) as the value for the PROJECT_NAME tag and set the environment variable to the right value before invoking doxygen. If you use bash, you can do:

PROJECT_NAME=`head -1 ../README` doxygen project.doxyfile

Which works nicely for me.
