PPIx::Regexp::Lexer(3)User Contributed Perl DocumentatioPPIx::Regexp::Lexer(3)

NAME
       PPIx::Regexp::Lexer - Assemble tokenizer	output.

SYNOPSIS
	use PPIx::Regexp::Lexer;
	use PPIx::Regexp::Dumper;
	my $lex	= PPIx::Regexp::Lexer->new('qr{foo}smx');
	my $dmp	= PPIx::Regexp::Dumper->new( $lex );
	$dmp->print();

INHERITANCE
       "PPIx::Regexp::Lexer" is	a PPIx::Regexp::Support.

       "PPIx::Regexp::Lexer" has no descendants.

DESCRIPTION
       This class takes	the token stream generated by PPIx::Regexp::Tokenizer
       and generates the parse tree.

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.

   new
       This method instantiates	the lexer. It takes as its argument either a
       PPIx::Regexp::Tokenizer or the text to be parsed. In the	latter case
       the tokenizer is	instantiated from the text.

       Any optional name/value pairs after the first argument are passed to
       the tokenizer, which interprets them or not as the case may be.

   errstr
       This method returns the error string from the last attempt to
       instantiate a "PPIx::Regexp::Lexer". If the last	attempt	succeeded, the
       error will be "undef".

   failures
	print $lexer->failures(), " parse failures\n";

       This method returns the number of parse failures	encountered. A parse
       failure is either a tokenization	failure	(see
       PPIx::Regexp::Tokenizer->failures()) or a structural error.

   lex
       This method lexes the tokens in the text, and returns the lexed list of
       elements.

SUPPORT
       Support is by the author. Please	file bug reports at
       <http://rt.cpan.org>, or	in electronic mail to the author.
