In a C program I have a numeric constant SIZE (that is in [1,32]),
that I can define when I compile the code, like this:
gcc -DSIZE=14 ...
How can I do the same thing in D? The solution I have found is to put
in the D code:
version(B1) const SIZE = 1;
version(B2) const SIZE = 2;
version(B3) const SIZE = 3;
version(B4) const SIZE = 4;
...
version(B14) const SIZE = 14;
...
And then compile the D program with:
dmd -version=B14 ...
Or:
ldc -d-version=B14 ...
Do you know nicer ways to do this in D? (if there are no nicer ways,
is this simple feature worth adding to D?)
Thank you, bye,

What I would probably do is generate a simple .d file right before you
compile.
I'm used to using forums where I can post, look at what I wrote, then
edit if necessary. To continue my thought, the file could be called
constants.d and it could contain just be just one line:
enum SIZE=14;
See, I need edit functionality :). s/just be just/just/
