NAME

6       PPIx::Regexp::Util - Utility functions for PPIx::Regexp;
7

SYNOPSIS

9        use PPIx::Regexp::Util qw{ __instance };
10            .
11            .
12            .
13        __instance( $foo, 'Bar' )
14            or die '$foo is not a Bar';
15

DESCRIPTION

17       This module contains utility functions for PPIx::Regexp which it is
18       convenient to centralize.
19
20       The contents of this module are private to the PPIx::Regexp package.
21       This documentation is provided for the author's convenience only.
22       Anything in this module is subject to change without notice. Caveat
23       user.
24
25       This module exports nothing by default.
26

SUBROUTINES

28       This module can export the following subroutines:
29
30   __instance
31        __instance( $foo, 'Bar' )
32            and print '$foo isa Bar', "\n";
33
34       This subroutine returns true if its first argument is an instance of
35       the class specified by its second argument. Unlike "UNIVERSAL::isa",
36       the result is always false unless the first argument is a reference.
37
38   __is_ppi_regexp_element
39        __is_ppi_regexp_element( $elem )
40          and print "$elem is a regexp of some sort\n";
41
42       This subroutine takes as its argument a PPI::Element. It returns a true
43       value if the argument represents a regular expression of some sort, and
44       a false value otherwise.
45
46   __ns_can
47       This method is analogous to "can()", but returns a reference to the
48       code only if it is actually implemented by the invoking name space.
49
50   __to_ordinal_en
51       This subroutine takes as its argument an integer and returns a string
52       representing its ordinal in English. For example
53
54        say __to_ordinal_en( 17 );
55        # 17th
56

SEE ALSO

58       Params::Util, which I recommend, but in the case of "PPIx::Regexp" I
59       did not want to introduce a dependency on an XS module when all I
60       really wanted was the function of that module's "_INSTANCE()"
61       subroutine.
