Starting with the usual turn-off disclaimer, "I'm new to D..." Sorry, but I'm in hair-tearing mode.

I'm trying to compile part of the sample code from dlang.org/phobos/std_regex.html:

import std.regex;
import std.stdio;

void main()
{
   // Print out all possible dd/mm/yy(yy) dates found in user input.
   auto r =
regex(r"\b[0-9][0-9]?/[0-9][0-9]?/[0-9][0-9](?:[0-9][0-9])?\b");
   foreach(line; stdin.byLine)
   {
     // matchAll() returns a range that can be iterated
     // to get all subsequent matches.
     foreach(c; matchAll(line, r))
       writeln(c.hit);
    }
}

What I'm getting is:

[0] (moller@qcore) >ldc2 -c re.d re.d
(13): Error: undefined identifier matchAll

So, what am I doing wrong?

You are using an ancient LDC version (based on 2.063, which was released three years ago almost to the day) that simply didn't have the API yet.

In general, this list intended to be used for Phobos development discussions. You might find that you get better answers to such questions at dm.D.learn (check out https://forum.dlang.org/ and the mailing list/NNTP interface links).

Best,
David

No idea, I just pasted your code in https://dpaste.dzfl.pl/cb18d29d187c and it works fine with dmd and ldc.

A few simple things you could try at this point:

* Search the stdlib source code for matchAll. You should find it.

* Try to qualify the name: std.regex.matchAll.

* Review your command line. It mentions "re.d" twice which is suspicious.

Thanks for the response.

After I upgraded from dmd 2.063 to 2.071, it worked.  I'm not sure what changed from one version to the next, but that seems to have been the problem.

Thanks,
Chris
