Hi!
I would like to have a "proxy" delegate, let's call it "foo" that
could point to a method or another, let's call them "fast_foo" or
"slow_foo" on the same object. This way depending on some
conditions I could switch at runtime from one set of methods to
others with a "switchFoo(" fast") m
Thanks to both, I got it. Type templates for generic types, and
alias for other things knowing that the instantiation is by
symbol.
Yes, the "alias this" in my message was a (double) brainfart, I
actually wanted to write "alias template".
In this case both functions had the same assembler b
Hi!
With "alias this" accepting runtime variables I'm struggling to
understand the difference between a generic function with an
"alias this" parameter and another one with a "runtime" parameter
of template type.
Example:
// example code
import std.stdio: writeln;
void writevalue
Hi,
Newbie question:
void foo(S)(S oneparam){}
void foo(S)(S oneparam, int anotherParam){}
alias fooStr = foo!string;
Gives:
"Error: template test.foo matches more than one template
declaration:"
How could I fix it so the alias aliases one of the two versions?
Also, why can't "fooStr" be a

I like this option more. I didn't knew you could assign to
"version".
Thanks,

Hi,
Probably I pretty simple question, how could I mark some code to

At first I tough I could do:

Then I tried to define a new version:

Hi,
I'm converting a C header file but there are two things left:
1. If the header file contains some D reserved word (in my case, "in" and
"out" in a struct) what is the best way to workaround it? Do you write
another C file and link about it?
2. What about va_list?

In Python and C# you can define a regex like:
"Blabla_(? \d{4}) _BLA
And then if you match that against a string like:
Blabla_1970_BLA
you can get a hash with "year" as key and 1970 as value. Can this be
done with D regex module? Trying it throws a RegExpException with the

What I've done profesionally and personally in the last year would be 90%

Hi,
I've just arrived to D 2.0 and after reading Andrei's book I'm loving
everything I'm seeing (except the bugs, of course).
I wanted to ask how these would be done, because I can't find how to do it:
