OK, today's release party wins. I've just uploaded the 8th package for release, and it's a very significant day of releases.
First, the PEAR website now supports patch tracking in its bug tracker, as well as the ability to auto-generate a package.xml based on the roadmap, complete with release notes based on closed bugs. This is pretty exciting stuff. 3 of the releases were devoted to the website pearweb package.
Next, I released PHP_ParserGenerator version 0.1.5, which fixes a bug and adds more display output
Finally, I just released the first full-featured parser for PHP, PHP_Parser, and its companion PHP_Parser_DocblockParser. These two packages are the next incarnation of the once-defunct PHP_Parser package. Based on a PHP_ParserGenerator-based grammar, the packages can parse any valid PHP 4, 5 or 6 (PHP 5.1.0+ is required for it to run, however). Needless to say, I have phpDocumentor in mind for immediate usage. The Docblock parser uses the docblock PECL extension to do its magic. Full regression tests are available for both packages. Documentation will be coming soon.
Note that all of the PHP_* packages are alpha state, so don't use them in production quite yet. However, do start playing around with them!
