PPIx::Regexp::Token::Code3pm
Represent a chunk of perl embedded in a regular expression.
Usage
use PPIx::Regexp::Dumper;PPIx::Regexp::Dumper->new('qr{(?{print "hello sailor\n"})}smx')->print;
Inheritance
"PPIx::Regexp::Token::Code" is a PPIx::Regexp::Token.
"PPIx::Regexp::Token::Code" is the parent of PPIx::Regexp::Token::Interpolation.
Overview
This class represents a chunk of Perl code embedded in a regular expression. Specifically, it results from parsing things like
(?{ code })(??{ code })
or from the replacement side of an s///e. Technically, interpolations are also code, but they parse differently and therefore end up in a different token.
This token may not appear inside a regex set (i.e. "(?[ ... ])". If found, it will become a "PPIx::Regexp::Token::Unknown".
Methods
This class provides the following public methods. Methods not documented here are private, and unsupported in the sense that the author reserves the right to change or remove them without notice.
is_matcher
This method returns "undef" because a static analysis can not in general tell whether an interpolated value matches anything.
ppi
This convenience method returns the PPI::Document representing the content. This document should be considered read only.
Note that if the location of the invocant is available the PPI document will have stuff prefixed to it to make the location of the tokens in the new document consistent with the location. This "stuff" will include at least a "#line" directive, and maybe leading white space.
