[PEPr] Changes in proposal for PHP::PHP_LexerGenerator

Greg Beaver (http://pear.php.net/user/cellog) has edited the proposal for PHP::PHP_LexerGenerator. Change comment: - Changed license to new BSD license - updated download link to version 0.2.0 - updated docs, the example lexer takes advantage of new regex features - Added regular expression parser, this adds tremendous flexibility * usage of internal sub-patterns is now allowed, and is passed to code handlers as variable $yy_subpatterns * usage of back-references is allowed for internal sub-patterns * usage of (?R) is allowed for recursive patterns and conditionals * usage of conditional patterns based on internal back-references or recursive back-reference (?(3)blah|foo) or (?(?R)blah|foo) is allowed * once-only patterns are allowed (?>blah) * usage of conditional patterns based on lookaheads are allowed (?(?=])x) (?(?=])x|y) * lookbehinds are impossible and are not allowed * setting PCRE internal options inside (?i) or (?i:blah) are not allowed - PHP_LexerGenerator_Exception extends PEAR_Exception I will call for votes in 7 days, please review now Please review the proposal: http://pear.php.net/pepr/pepr-proposal-show.php?id=415 -- Sent by PEPr, the automatic proposal system at http://pear.php.net
