I especially like registering functions that take the
parameters with
the types they need from the regexp captures, as well as the
compile-time failures that come from that if done incorrectly.
Now I just need to use in "real life".
BTW, why is the description passed as a template argument to
the Cucumber keywords. @Given!("foo") instead of @Given("foo")?
Ehm... because until now I didn't know that @Given("foo") was
possible. In my head I was doing compile-time stuff so
everything had to be compile-time, if that makes any sense.
After I read the above I wasn't even sure how @Given("foo")
would work so I wrote some code and now know that all I need is
a struct with a regular string field. I think the documenation
on http://dlang.org/attribute.html is severely lacking.
I think I have some refactoring to do now. Thanks for pointing
this out!

Hmm. So for the string argument is fine, unfortunately I also
need to know the line number of the step definition, and that
doesn't work:
struct Given {
this(string s, ulong l = __LINE__) {
this.s = s;
this.l = l;
}
string s;
ulong l;
}
@Given("foobar")
auto func() pure nothrow @safe {
}
void main() {
foreach(attr; __traits(getAttributes, func)) {
pragma(msg, "s is ", __traits(getMember, attr, "l"));
}
}
I get:
s is attr_str.d(21): Error: variable attr cannot be read at
compile time
attr_str.d(21): while evaluating pragma(msg,
__traits(getMember, attr, "l"))
