Hi, This is to remind everyone of the formal review of Eric Niebler's xpressive library. The review period is scheduled to end Sunday, September 18. I want to especially point out the xpressive is not just another 'regex' library. It goes beyond the scope of regular regex (no pun intended) engines. Here is what Eric has to say: "Although xpressive's primitives are regex-ish in nature, xpressive is far more than just a regular expression engine. It is a pattern matching engine with the power of context-free grammars. By allowing you to embed one pattern in another by reference, xpressive lets you find patterns in data that are recursive in nature. Problems that are intractible with "classic" regular expressions, such as matching balanced nested parentheses or matching XML tags, are simple with xpressive. So xpressive is more rightly thought of as a context-free grammar engine with exhaustive backtracking. The goal is to provide one framework and one set of pattern matching primitives that scales from simple strstr-style grepping, through ordinary regexing, all the way to full-blown parsing." For a glimpse of what xpressive can do look at "Grammars and Nested Matches" here: http://tinyurl.com/d7637 This link takes you to the online docs.
