Instaparse <https://github.com/Engelberg/instaparse/> is an easy-to-use, feature-rich parser library. The big idea behind instaparse is to make it simple to convert grammars to parsers without needing to know the idiosyncrasies of LL1, LALR, and other esoteric grammar restrictions imposed by most parser generators.
Here are the highlights of the new 1.2.0 release: 1. Several significant performance improvements. 2. Two new functions, `span` and `visualize` which allow you to better understand the structure of your parse tree. https://github.com/Engelberg/instaparse/#understanding-the-tree 3. A new optional keyword argument to `parse` and `parses` that allows you to reveal hidden information, primarily for debugging purposes. https://github.com/Engelberg/instaparse/#revealing-hidden-information I've received a few questions from instaparse users who wanted to know if I had any performance tips. Since version 1.2.0 is primarily a performance-oriented release, it seemed fitting to include, as part of the release, a list of performance tips as well as an expanded essay about instaparse's performance and what I'm striving for. https://github.com/Engelberg/instaparse/blob/master/docs/Performance.md Thanks to everyone who provided feature requests on the github site, and especially to those who tracked along with the 1.2.0-SNAPSHOT releases and provided feedback for this new release. -- -- You received this message because you are subscribed to the Google Groups "Clojure" group.
