NAME

PPIx::Regexp::Token::Interpolation - Represent an interpolation in the PPIx::Regexp package.

SYNOPSIS

use PPIx::Regexp::Dumper;
PPIx::Regexp::Dumper->new('qr{$foo}smx')->print();

INHERITANCE

PPIx::Regexp::Token::Interpolation is a PPIx::Regexp::Token::Code.

PPIx::Regexp::Token::Interpolation has no descendants.

DESCRIPTION

This class represents a variable interpolation into a regular expression. In the "SYNOPSIS" the $foo would be represented by an object of this class.

Incompatible Change: Parse of '@{[ ... ]}'

In versions 0.083 and earlier, '@{[ ... ]}' parsed as a member of this class. In 0.084 and later, it parses as a member of PPIx::Regexp::Token::Code. This more accurately reflects the actual contents of the token, and enables the recognition of the full range of postfix dereference operators for versioning purposes, not just those valid in interpolations.

METHODS

This class provides the following public methods beyond those provided by its superclass.

is_matcher

This method returns undef because a static analysis can not in general tell whether a piece of code matches anything.
