I want to mixin only name - not the full function code.
You can't. Best you can do is write the function separately and
then mixin an alias for it with the other name.
void main()
{
enum letters = ['A', 'B', 'C'];
// normal implementation, parameterized via template
void printImplementation(char ch)(uint i) {
import std.stdio;
writeln(ch, " - ", i);
}
static foreach(ch; letters)
{
// mixin the name separately
mixin("alias print" ~ ch ~ " = printImplementation!ch;");
}
printB(6);
}
Though, I'd point out the mixin code doesn't have to be too ugly.
Consider this:
void main()
{
enum letters = ['A', 'B', 'C'];
static foreach(ch; letters)
{
mixin(q{
void print}~ch~q{(int i) {
import std.stdio;
writeln(ch, " - ", i);
}
});
}
printB(6);
}
Well, the name part is a big ugly, but the rest of it looks
perfectly normal, and the compiler error message still give
reasonable results.
