I'd probably just do
void doSwitch(items...)(int i) {
switch(i) {
static foreach(idx, item; items) {
case idx:
item();
return;
}
}
}
That should work pretty simply.
enum temp = [FunctionNames].join(", ");
enum switchEnum = "{" ~ temp ~ "};";
Were you trying to do a mixin here? The error you mention below
is trying to use this switchEnum thing as a type... and it isn't
a type, it is just a string. the mixin() is necessary to compile
it into code and thus create that type.
mixin("enum switchEnum = { " ~ temp ~ "}");
but I think even attempting this is overcomplicating.
static foreach (name; FunctionNames)
{
name ~ " : " ~ name ~ "(); break;";
}
ditto down here too.
