Is it possible to enumerate all functions in a module? I'd like my test program to find the functions in a fibrary with a particular attribute defined, but I can't find any way to do this. I've looked in std.traits; maybe I'm missing something.

Ah, allMembers does the trick. Probably could have spent a bit longer googling that one before posting!

Well I just made this for you, so here it is anyway:

module mymodule;
import std.stdio : writeln;

void main() {
	foreach(m; __traits(allMembers, mymodule)) {
		static if (__traits(isStaticFunction, __traits(getMember, mymodule, m))) {
			writeln(m);	
		}
	}
}

void myfunc() {
}

Output:

main
myfunc

I wonder whether we could have a 'D recipes' page on the wiki, since some question appear regularly. Does one already exist?

Thanks, that's very helpful; it answered my next question which was going to be why __traits(someTrait, nameOfSymbolInAnotherModule) didn't work.

I don't know.
Other than the Rosetta code stuff, I believe there is nothing [0].
However we need to work on D idioms and patterns as well as examples of code.
If your wanting to lead please do :)

Doesn't have much, but there's a start there.

Ah, I found one:

http://wiki.dlang.org/Cookbook

Obviously, I didn't know this page existed.

Well, I'm trying to understand how to add a new recipe, with the correct tag.

There, here it is:

http://wiki.dlang.org/Finding_all_Functions_in_a_Module

Feel free to edit it!

I'm a bit confused about how this example works. I thought foreach was a runtime loop, so how does nesting static ifs inside it work?
