== Visual [[REPL]] with Charts ==

The [[GraalVM]] (version 0.9 and newer) comes with command line [[REPL]]. However in today's modern era nobody wants a [[CLI]] right? Everyone wants nice graphs! Luckily there is visual [[REPL]] written by me with the help of [[DukeScript]]. Try it as:

<source lang="bash">
$ hg clone http://source.apidesign.org/hg/truffledebugdemo repl+charts
$ cd repl+charts/
$ hg up -C Charts
$ JAVA_HOME=~/bin/graalvm mvn install exec:exec
</source>

The '''JAVA_HOME''' has to point to your downloaded version of [[GraalVM]] (version 0.9 at least). But then we can have visualization from any [[Truffle]] language, for example [[JavaScript]] array:
