Tie::Hash::NamedCapture - phpMan

NAME
    Tie::Hash::NamedCapture - Named regexp capture buffers

SYNOPSIS
        tie my %hash, "Tie::Hash::NamedCapture";
        # %hash now behaves like %+

        tie my %hash, "Tie::Hash::NamedCapture", all => 1;
        # %hash now access buffers from regexp in $qr like %-

DESCRIPTION
    This module is used to implement the special hashes "%+" and "%-", but
    it can be used to tie other variables as you choose.

    When the "all" parameter is provided, then the tied hash elements will
    be array refs listing the contents of each capture buffer whose name is
    the same as the associated hash key. If none of these buffers were
    involved in the match, the contents of that array ref will be as many
    "undef" values as there are capture buffers with that name. In other
    words, the tied hash will behave as "%-".

    When the "all" parameter is omitted or false, then the tied hash
    elements will be the contents of the leftmost defined buffer with the
    name of the associated hash key. In other words, the tied hash will
    behave as "%+".

    The keys of "%-"-like hashes correspond to all buffer names found in the
    regular expression; the keys of "%+"-like hashes list only the names of
    buffers that have captured (and that are thus associated to defined
    values).

    This implementation has been moved into the core executable, but you can
    still load this module for backward compatibility.
