Hi all, I've released an alpha quality Clojurescript port of Mark Engelberg's fantastic parsing library, Instaparse (https://github.com/Engelberg/instaparse). The Clojure code is still retained in this project, so it is still Clojure compatible. Once battle tested, the aim is to merge this upstream.
You can use it via the leiningen coordinates: [com.lucasbradstreet/instaparse-cljs "1.3.4.2"] and can find the code here: https://github.com/lbradstreet/instaparse-cljs A few points of difference between the Clojure and Clojurescript versions of this library: * Visualisation is not supported as it depends on Rhizome on the JVM. * Slurping grammars is not supported, as slurp cannot be used from clojurescript. * The Clojurescript version is slower by approximately a magnitude (tested with V8, :advanced compile). Performance with optimizations :none will be slower by around another factor of 3. Please let me know if you are using a grammar that performs especially badly in the Clojurescript version compared to the Clojure version. Any help with optimizations here would be appreciated. Note that some grammars will have a large upfront initial parsing cost that could be prohibitive for some client side use cases. Note that you can serialize the parsed grammars and load them client side, avoiding this cost. * You will probably require a recent version of Clojurescript. I have not tested it against old versions. This work would not have been possible without the previous work by Russell Mull (https://github.com/mullr) and Ryan Berdeen (https://github.com/also/). Please let me know if you encounter any issues at all. All the tests pass and it works for my parsers, but I'm sure there are some issues lurking.
