You might like my embedded graphics/GUI library then. Everything that can be done with preprocessor macros is done using preprocessor macros:https://bitbucket.org/Tectu/ugfx/src/fb100bcc25225cfad0bab5d40bef1db703e9670a/src/gdisp/gdisp_colors.h?at=master&fileviewer=file-view-default

Right ... because my life doesn't suck enough and I would like to suffer more? I'm with @Wieland on that preprocessor magic - I avoid as the devil avoids incense ... there's a whole battery of cheat-sheets for dealing with that ugly monster ...Read and abide by the Qt Code of Conduct

If your target processor runs on 64 MHz and has 32 kB RAM and you want to do some graphics/GUI on it, you might be thankful that there are masochistic people out there :)Of course I'd never do that on a desktop system.
Actually, the real problem I see with preprocessor macros is not actually writing and maintaining them but debugging them.

One of the reasons I stick to real CPUs. ;)
Joke aside, I leave that not-enough ram/CPU time struggle to engineers/embedded devs, I don't have the stomach for it to be honest. :DAs a side note I'm not completely convinced using
#definefor constants is really warranted.
If you're doing a comparison for example, this would (if I remember correctly) expand to something along the lines of:mov eax, 0x... # Set the constant test eax, [0x...] # Do the comparison with a field from memoryIf you use a simple constant (const static variable), the above should be pretty much the same:
mov eax, [0x...] # Set the constant (from memory this time) test eax, [0x...] # Do the comparison with a field from memory
