Hello
I want to define an enum int, but I want to make it possible to
set its value when I run dmd from the command line. Is it
possible in D?
No, D does not allow passing values via the compiler command
line. You can use the -debug=xxx or -version=xxx to enable
debug(xxx) or version(xxx) blocks.
For arbitrary values, you will need intermediary files. You can
use the import(filename) construct to read a file from disk
during compilation, like so:
echo 42 > foo.txt
cat > test.d
import std.conv, std.string;
enum foo = to!int(import("foo.txt").strip());
^D
dmd -J. test.d
