ppix::regexp::lexer
PPIx::Regexp::Lexer(3) User Contributed Perl Documentation PPIx::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
";
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.
