Is there a way to edit my preprocessor commands or create new ones?
If all else fails, I could write a simple program to read the cpp file, search for "TODO" and directly replace that with #prama message, and finally add that to the makefile. Call it a kind of a pre-compiler macro expansion/filter thingy...?
My problem is that it's a hobby project, so there's always something more interesting that I want to work on and the boilerplate code is being put off. I thought the #warning macro would be too annoying, but on second thought I want the TODOs to stand out and annoy me every time I compile so that I can't ignore them so easily.
I have decided that #warning is simple enough to type out and doesn't clutter things badly, so that is how I will proceed.
I think for things that really can sit for a longer time I'll use your method too, thank you dhayden.
Edit: Have now implemented this on all my empty functions. Have already crossed out half of them. Feels so cathartic to cut through those warnings. I totally recommend for hobby projects.
