How can I edit makefile to change Doxyfile settings?

Question

I have the below code in my makefile. The makefile generates a Doxyfile with standard configurations. I want to change the UML_LOOK tag to YES and GENERATE_TREEVIEW to YES without having to edit the file manually. Is there a way of passing commands to the makefile so it does the job itself?

doc:
    doxygen -g Doxyfile
    doxygen Doxyfile
    rm -rf latex

Answer 1

You can add sed commands to edit the Doxyfilein place just after its generation:

sed -i '/UML_LOOK.*=/s/^.*$/UML_LOOK = YES/' Doxyfile
sed -i '/GENERATE_TREEVIEW.*=/s/^.*$/GENERATE_TREEVIEW = YES/' Doxyfile

And if you don't need LaTeX output, you can change the GENERATE_LATEX option the same way instead of removing latex directory afterwards.
