PPIx::Regexp::Token::Delimiter(3)
NAME
PPIx::Regexp::Token::Delimiter - Represent the delimiters of the
regular expression
SYNOPSIS
use PPIx::Regexp::Dumper;
PPIx::Regexp::Dumper->new( 'qr{foo}smx' )
->print();
INHERITANCE
"PPIx::Regexp::Token::Delimiter" is a PPIx::Regexp::Token::Structure.
"PPIx::Regexp::Token::Delimiter" has no descendants.
DESCRIPTION
This token represents the delimiters of the regular expression. Since
the tokenizer has to figure out where these are anyway, this class is
used to give the lexer a hint about what is going on.
METHODS
This class provides no public methods beyond those provided by its
superclass.
perl_version_introduced
Experimentation with weird delimiters shows that they did not actually
work until Perl 5.8.3, so we return '5.008003' for such delimiters.
perl_version_removed
Perl 5.29.0 made fatal the use of non-standalone graphemes as regular
expression delimiters. Because non-characters and permanently
unassigned code points are still allowed per perldeprecation, I take
this to mean characters that match "/\p{Mark}/" (i.e. combining
diacritical marks). But this regular expression does not compile under
Perl 5.6.
So:
This method returns '5.029' for such delimiters provided the requisite
regular expression compiles. Otherwise it return "undef".
