ClojureScript, the Clojure compiler that emits JavaScript source code.
README and source code: https://github.com/clojure/clojurescript
New release version: 0.0-3058
Leiningen dependency information:
[org.clojure/clojurescript "0.0-3058"]
This is a significant enhancement release around REPLs and compile times.
All builtin REPLs (Nashorn, Node.js, Rhino and the browser REPL) now
support the helper functions normally available via clojure.repl,
these include: doc, find-doc, apropos, dir, source, and pst. All of the
builtins REPL now also support source mapped stacktraces.
This release also includes many enhancements around compile times.
ClojureScript now ships with a default :optimizations setting of
:none. Implicit now when using :none is source map generation and analysis
caching. Analysis caching significantly speeds up compile times.
The standard library (cljs.core) is now AOTed compiled to JavaScript
along with an AOTed analysis dump and an AOTed source map. This
dramatically cuts down on cold start compile times. The standard
library is never actually ever analyzed or compiled in your own
builds. The result is particularly dramatic for REPLs.
ClojureScript is also now available for the first time as a standalone
AOTed JAR. The Quick Start introduction has been rewritten in terms of
the standalone JAR:
https://github.com/clojure/clojurescript/wiki/Quick-Start
The new Quick Start is essential reading even if you are a relatively
experienced ClojureScript developer.
As usual feedback welcome!
