NAME
PPIx::Regexp::Util - Utility functions for PPIx::Regexp;
SYNOPSIS
use PPIx::Regexp::Util qw{ __instance };
.
.
.
__instance( $foo, 'Bar' )
or die '$foo is not a Bar';
DESCRIPTION
This module contains utility functions for PPIx::Regexp which it is
convenient to centralize.
The contents of this module are private to the PPIx::Regexp package.
This documentation is provided for the author's convenience only.
Anything in this module is subject to change without notice. Caveat
user.
This module exports nothing by default.
SUBROUTINES
This module can export the following subroutines:
__instance
__instance( $foo, 'Bar' )
and print '$foo isa Bar', "\n";
This subroutine returns true if its first argument is an instance of
the class specified by its second argument. Unlike "UNIVERSAL::isa",
the result is always false unless the first argument is a reference.
__is_ppi_regexp_element
__is_ppi_regexp_element( $elem )
and print "$elem is a regexp of some sort\n";
This subroutine takes as its argument a PPI::Element. It returns a true
value if the argument represents a regular expression of some sort, and
a false value otherwise.
__ns_can
This method is analogous to "can()", but returns a reference to the
code only if it is actually implemented by the invoking name space.
__to_ordinal_en
This subroutine takes as its argument an integer and returns a string
representing its ordinal in English. For example
say __to_ordinal_en( 17 );
# 17th
SEE ALSO
Params::Util, which I recommend, but in the case of "PPIx::Regexp" I
did not want to introduce a dependency on an XS module when all I
really wanted was the function of that module's "_INSTANCE()"
subroutine.
