## What's new in peasy ### what's new in 0.3.2 * dont use gruntjs any more, use gulpjs instead. * use gulp-twoside.js to wrap module for browser * add lineparser to support lineno and row. ### what's new in 0.3.1 * add member "base" to peasy.Parser, to support modularization * exports.debug and exports.warn ### what's new in 0.3.0 * new class based api * samples: arithmatic, arithmatic2, dsl * rewrite readme.md * grunt work flow * rearranges folder, split coffee and js folder. ### what's new in 0.2.8 * add logic features ### what's new in 0.2.7 * remove the parameter `start` from the matcher functions * `orp` play well in testpeasy ### what's new in 0.2.6 * better support to modular grammar * simpler method to declare left recursive rule and memorized rule ### what's new in 0.2.5 * classpeasy become modular Peasy, and becomes the default module peasy.js(peasy.coffee for coffeescript) * original peasy.js(coffee) become nonmodularpeasy.js(coffee) * document on modular [Peasy](http://chaosim.github.io/peasy/doc/peasy.html) * document on nonmodular [Peasy](http://chaosim.github.io/peasy/doc/nonmodularpeasy.html) ### what's new in 0.2.4 * classpeasy: which provides class Parser and TextParser ### what's new in 0.2.3 * just for test npm readme ### what's new in 0.2.2 * just for test npm readme ### what's new in 0.2.2 * split peasy.coffe to peasy.coffee and autopeasy.coffee * more combinators: optional, any, some, times, separatedList, timesSeparatedList, follow * document: annotated peasy.coffee ### what's new in 0.2.0 * the functions to gather information about left recursive symbol automaticly * the functions to help yourself to set left recursive symbol by hand. * the above utilities use recursive to wrap the left left recursive symbol * use memorize and memo to help cache the parsing result for any grammar symbol. * some functions to demonstrate the method to write the matchers for peasy yourself, such as andp, orp, spaces, etc.
