Question

I am trying to use DRY methodologies on an arbitrary collection of mixed-case words such that the text MixedCase could produce both:

• The compile-time string "MixedCase"
• The compile-time variable const int MIXEDCASE_ID

I am using gcc, and gcc extensions would be acceptable.

Is it possible for C++ to convert test in the code to uppercase?  E.g., such that

  CONVERT(abc)

would produce the symbol ABC? If not, is there a solution beyond typing every sample twice in the code?

Edit: Consider that there is no restriction on the input format. Mixed or "Mixed" or 'M', 'i', 'x', 'e', 'd' or 0x4d 0x69 0x78 0x65 0x64 (yuck?)…

Answer 1

To do this you would need to write a build tool that preprocessed (actually prepreprocessed) your source files to make this conversion. There is no built-in feature in gcc that can do this at compile time.
