Hello,
I am currently porting the frontend of my instrumenting profiler
to D. It features a C++-makro that profiles the time between
entering and leaving a scope (achieved with con-/destructors in
C++). Since D has scopeguards, I hoped to achieve this by
creating a mixin that generates the following code:
measure("func1");
scope(exit) measure("func1");
Since I of course don't want to type a mixin for that everytime I
want to use it, I tried to alias it:
import std.meta : Alias;
alias profile_scope(string name) = Alias!(mixin("measure(\"" ~
name ~ "\"); scope(exit) measure(\"" ~ name ~ "\");"));
I expected this to generate the code above by typing
profile_scope("func1") in my programm. However the compiler (dmd)
gives me the following error:
source\main.d(24): Error: template plattform.profile_scope cannot
deduce function from argument types !()(string), candidates are:
source\plattform.d(262): plattform.profile_scope(string
name)
This looks like a deduction/overload kind of error, which has me
completly confused since there is no other identifier of the name
"profile_scope" in my programm and the error message shows only
one candidate.
Is there any way I can achive generating those two statements
using only something that effectively looks like a function
call/C-macro with an argument?
