I have no idea if this has been discussed yet, but I was
thinking it would be neat to have benchmark blocks that only
run when specified, like how unittest works.
Code:
benchmarks
{
import std.conv : to;
int a;
void f() {auto b = to!string(a);}
auto r = benchmark!(f)(10_000);
auto f0Result = to!Duration(r[0]);
writeln(f0Result)
}
Example:
rdmd -benchmarks -main myapp.d
Alternatively, the writeln could be replaced with some kind of
standard benchmark output utility (similar to the idea of
assert when used for unit tests).
Thoughts?
I think this can be implemented via a library solution pretty
neatly. I was playing with something recently, and I ended up
writing an RAII benchmark thing.
{
auto b = Benchmark("name here");
// Run code here.
}
With the syntax above in mind, you can write a constructor and a
destructor for Benchmark which start and stop a timer and then
print the results. I got it working before, and it was kind of
fun. Another idea is to do this.
@benchmark
void nameHere() {
// Run code here.
}
Then you can write something or other which finds functions with
the @benchmark attribute and runs a timer as before, etc.
Why add extra syntax for what you can already do pretty nicely
with a library?
