Hello,

I read the library reference for regex.

I really miss python's equivalent of finditer.

Sometimes matching is not on purpose and one will want to match all the occurences to iterate over it since it is much more regarding concerning the orders and repetitions.


my code :
-----------------------------------------------------------------------------
version(Tango) extern (C) int printf(char *, ...);

import std.stdio;
import std.regex;
import std.file;
import std.format;

int main(char[][] args)
{
    string fl = readText("testregexd.txt");

    auto m = match(fl, regex(`(<n=(?:hello|goodbye))*`,"g"));
    auto c = m.captures;

    writeln(c);

    return 0;
}

---------------------------------------------------------------------------

Content of testregexd.txt:
----------------------------------------------------------------------------

<n=hello <n=goodbye

----------------------------------------------------------------------------

Any way to workaround ?

Thanks !

Larry

Have you tried iterating over m? This works for me:

import std.stdio;
import std.regex;
import std.file;
import std.format;

int main(char[][] args)
{
    string fl = "
<n=hello <n=goodbye
";

    auto m = match(fl, regex(`(<n=(?:hello|goodbye))`,"g"));
    foreach (c; m)
        writeln(c);

    return 0;
}

Humm,

A copy-paste of your code lead to :

"[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[segmentation fault"

So it doesn't work for me.

I use gdc if it might help !

It looks like a _very_ old GDC. What's you version string/OS/package ?

I have gdc 4.6 on Debian testing.

Is that so old ?

That is extremely old. You want to get gdc-4.8.1 from unstable, if you can. A great number of bugs have been fixed since gdc-4.6; in fact, the entire std.regex has been replaced, which is probably why you're seeing these problems with regexes that the rest of us don't see.
