NAME

       PPIx::QuoteLike::Utils - Utility subroutines for PPIx::QuoteLike;

SYNOPSIS

        use PPIx::QuoteLike::Utils qw{ __variables };

        say for __variables( PPI::Document->new( \'$foo' );

DESCRIPTION

       This Perl module holds code for PPIx::QuoteLike that did not seem to fit anywhere else.

SUBROUTINES

       This module supports the following public subroutines:

   __variables
        say for __variables( PPI::Document->new( \'$foo' );

       Despite the leading underscores, this exportable subroutine is public and supported. The
       underscores are so it will not appear to be public code to various tools when imported
       into other code.

       This subroutine takes as its only argument a PPI::Element, and returns the names of all
       variables found in that element, in no particular order. Scope is not taken into account.

       In addition to reporting variables parsed as such by PPI, and various corner cases such as
       "${]}" where PPI is blind to the use of the variable, this subroutine looks inside the
       following PPI classes:

           PPI::Token::Quote
           PPI::Token::QuoteLike::Backtick
           PPI::Token::QuoteLike::Command
           PPI::Token::QuoteLike::Readline
           PPI::Token::HereDoc

       If PPIx::Regexp is installed, it will also look inside

           PPI::Token::QuoteLike::Regexp
           PPI::Token::Regexp::Match
           PPI::Token::Regexp::Substitute

       Unfortunately I can not make "PPIx::Regexp" a requirement for this module, because of the
       possibility of a circular dependency.
