Hi!
I am want to extend available enum to provide more items to them.
How I can do this job without manual copying of exsisting enum items?
If what you want is a new enum that contains the values of an existing
enum,
with some additions, this code will do it:
string EnumDefAsString(T)() if (is(T == enum)) {
string result = "";
foreach (e; __traits(allMembers, T)) {
result ~= e ~ " = T." ~ e ~ ",";
}
return result;
}
template ExtendEnum(T, string s) if (is(T == enum) &&
is(typeof({mixin("enum a{"~s~"}");}))) {
mixin("enum ExtendEnum {" ~
EnumDefAsString!T() ~ s ~
"}");
}
Has D considered introducing string interpolation? That looks very hard
to read...
