I am trying to create a template function with a switch case
inside it.
The function signature is:
`static void doSwitch(T...)(int i)`
The code it must generate for `doSwitch!(foo, bar)()` is
`{
switch (int)
{
foo:
foo();
return;
bar:
bar();
return;
}
}`
It would be nice if this function would cast `i` to an enum too
so that I can put down a breakpoint in a debugger and maybe add
some logging, but that is not strictly neccesary.
The code I have right now is:
`
template switchEnum(FunctionNames...)
{
enum temp = [FunctionNames].join(", ");
enum switchEnum = "{" ~ temp ~ "};";
}
static void doSwitch(FunctionNames...)(int i)
{
auto functionName = cast(switchEnum!FunctionNames) i;
switch (functionName)
{
static foreach (name; FunctionNames)
{
name ~ " : " ~ name ~ "(); break;";
}
}
}
`
But I can't get it to work and am hitting a dead end.
The error I get:
`Error: switchEnum!(foo, bar) is used as a type`
