           Summary: regex(replace with delegate) sample doesn't work
           Product: D
           Version: D2
          Platform: Other
        OS/Version: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: nobody puremagic.com
        ReportedBy: zan77137 nifty.com
        Depends on: 1904

This code doesn't work!


import std.regex, std.string;

void main()
{
    string baz(RegexMatch!(string) m)
    {
        return std.string.toupper(m.hit);
    }
    auto s = replace!(baz)("Strap a rocket engine on a chicken.",
        regex("[ar]", "g"));
}


RESULT:
    std/regex.d(2840): Error: struct std.regex.RegexMatch!(string).RegexMatch
member test is not accessible


See also:
    http://ideone.com/7pGAm


Workaround:
Define the dummy free function for RegexMatch!(string).test.

private bool _dummyTest(Engine)(Engine r, size_t idx)
{
    return r.test(idx);
}


Note:
This issue is maybe related with bug 1904.
- Template function's alias parameter takes delegate.
- Template function uses same module's structs or classes and calls their
private function.

Reopened as the reason it works is that the bug has been worked around in
phobos, not fixed.  It still needs to be reduced with an older version of
phobos, or possibly closed as a duplicate.

I seriously dunno what to do about this bug report:

- the code of current std.regex changed so that sample no longer compiles

- even then Phobos worked around the issue back then when 2.053 was all the
rage

- even if the exact code where it failed is dug up there are chances it won't
compile on latest dmd

So somebody would have to chase down the original situation to see if it's
still a bug in dmd.

Dmitry, any chance you could close this by (a) submitting a pull request
changing the code sample so that it works, and (b) submitting a bug report for
dmd? Thanks!

'a' is impossible since the question is about this particular sample presented in Bugzilla (and there is no pull request for that ;) ) that's no longer applicable. See new example that uses Captures!string: http://dlang.org/phobos/std_regex.html#.replace I'll try my hand at 'b' but it's tricky as it involves at least a getting problem statement. And to do that... 1) Get the old phobos with std.regex 2) Run compiler(s) starting from 2.042+ and/or patching old source so that it works with later compiler 3) Recreating error with the current HEAD (if it's not fixed yet) -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
