is_ppi_regexp_element¶

 is_ppi_regexp_element( $elem )
   and print "$elem is a regexp of some sort\n";

This subroutine is public and supported.

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.

__instance¶

 __instance( $foo, 'Bar' )
     and print '$foo isa Bar', "\n";

This subroutine is private to the "PPIx-Regexp" package.

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 is private to the "PPIx-Regexp" package.

This is a synonym for is_ppi_regexp_element(), and is deprecated in favor of it. If called, it will complain via "Carp::cluck()" and then "goto &is_ppi_regexp_element".

__merge_perl_requirements¶

This subroutine is private to the "PPIx-Regexp" package.

This subroutine merges perl requirements as returned by the various "__perl_requirements()" methods.

__ns_can¶

This subroutine is private to the "PPIx-Regexp" package.

This method is analogous to "can()", but returns a reference to the code only if it is actually implemented by the invoking name space.

__post_rebless_error¶

This method is private to the "PPIx-Regexp" package. The intended use is to alias it to "__PPIX_ELEM__post_reblessing()".

It takes arguments as name/value pairs. Argument "{error}" is the error message; if it is omitted you get a warning with stack trace. Argument "{explanation}" defaults to "{error}".

It returns the number of errors to add to the parse.

raw_width¶

This public method returns the minimum and maximum width matched by the element before taking into account such details as what the element actually is and how it is quantified.

This implementation is appropriate to things that match exactly one character -- i.e. it returns "( 1, 1 )".

__to_ordinal_en¶

This subroutine is private to the "PPIx-Regexp" package.

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

width¶

 my ( $min_wid, $max_wid ) = $self->width();

This public method (well, mixin) returns the minimum and maximum width of the text matched by the element.

Elements which import this method must also implement a "raw_width()" method which returns the unquantified width of the element.

all¶

This tag exports everything exportable by this module.

width_one¶

This tag is appropriate to an element which, when unquantified, matches exactly one character. It exports "raw_width()" and "width()".
