PPIx::Regexp::Util - Utility functions for PPIx::Regexp;
use PPIx::Regexp::Util qw{ __instance }; . . . __instance( $foo, 'Bar' ) or die '$foo is not a Bar';
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.
This module can export the following subroutines:
__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.
UNIVERSAL::isa
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
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.
PPIx::Regexp
_INSTANCE()
