Bootstrapping the Compiler

ClojureScript cannot currently compile itself. The following enumerates the remaining tasks:

• Portable tools.reader that runs on Node.js. (see cljs-tools.reader port in progress)
• ClojureScript compiler source conditionalized with feature expressions to map Clojure types* to ClojureScript ones: clojure.lang.PersistentVector -> cljs.core/PersistentVector
• Port all relevant macros* - currently we import several macros from Clojure itself

* you can use the CLJS API reference to help identify imported macros and related Clojure types

cljs-in-cljs from 2012

As a point of reference, https://github.com/kanaka/clojurescript is a previous project to bootstrap the ClojureScript compiler. It is fairly dated since it was forked from the main tree on Nov 16th, 2012, however, it was self-hosting and allowed for a fully browser-based REPL: http://clojurescript.net/ A presentation of the project from Clojure West 2013 is here: http://www.infoq.com/presentations/cljs-in-cljs
