           Summary: ctRegex - named submatch - hash-table exception
           Product: D
           Version: D2
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Phobos
        AssignedTo: nobody puremagic.com
        ReportedBy: wyrlon gmx.net



Reported on v2.060 (but no version seems to work).

The code is based on the opIndex example from:
http://dlang.org/phobos/std_regex.html#regex

The normal regex version is functional, but when converting to ctRegex, the
hashtable lookup throws.(

auto m = match("a = 42;", 
ctRegex!(`(?P<var>\S+)\s*=\s*(?P<value>\d+);`));
auto c = m.captures;

// c["var"]; =>
core.exception.RangeError std.regex(2145): Range violation

// c["value"]; =>
Object.Exception C:\D\dmd2\windows\bin\..\..\src\phobos\std\regex.d(2145): 
no submatch named value

Just spent an hour duplicating this one.

Bump.

Since ctRegex is an "Experimental feature.", it may be worth documenting the


If we don't know how to fix this, it may also be worth temporarily and
statically turning down named captures in static regexes, with a "sorry"
message.

Turns out it's not hashtable but rather binary search on a broken array :(
The good news is that the fix turns out to be trivial.
