PPIx::QuoteLike::Utils(3)
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.
