Setelah selesai, scalash harus dibuat executable dengan perintah berikut (asumsi: scala terinstall di ~/software/scala-2.7.7/):
[bpdp@bpdp-arch ~]$ chmod +x software/scala-2.7.7.final/bin/scalash
Pada awalnya, jika dijalankan akan muncul error berikut ini:
[bpdp@bpdp-arch ~]$ scalash Scala Shell version 0.1 ($(java.vm.name), Java 1.6.0_18) scala:0> Exception in thread "main" java.lang.ClassNotFoundException: binder0 at scala.tools.nsc.interpreter.AbstractFileClassLoader.findClass(AbstractFileClassLoader.scala:27) at java.lang.ClassLoader.loadClass(ClassLoader.java:321) at java.lang.ClassLoader.loadClass(ClassLoader.java:266) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:334) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:264) at scala.tools.nsc.Interpreter.bind(Interpreter.scala:543) at org.scalashell.scalash.ScalaShell$$anonfun$bindSettings$1.apply(ScalaShell.scala:64) at org.scalashell.scalash.ScalaShell$$anonfun$bindSettings$1.apply(ScalaShell.scala:61) at scala.tools.nsc.Interpreter.beQuietDuring(Interpreter.scala:110) at org.scalashell.scalash.ScalaShell.bindSettings(ScalaShell.scala:61) at org.scalashell.scalash.ScalaShell.repl(ScalaShell.scala:106) at org.scalashell.scalash.ScalaShell.run(ScalaShell.scala:183) at org.scalashell.scalash.Main$.main(Main.scala:54) at org.scalashell.scalash.Main.main(Main.scala) [bpdp@bpdp-arch ~]$
Workaround untuk error tersebut adalah dengan menjalankan scalash di direktori $SCALA_HOME/lib. Berikut adalah snapshotnya:

Kelihatannya scalashell memerlukan beberapa file .jar dari Scala sekaligus membuat beberapa class (temporary?) seperti di atas (lihat beberapa file .class) yang muncul setelah dijalankan di direktori lib ini.
Dari apa yang telah saya kerjakan, scalash ini lebih nyaman digunakan daripada REPL scala bawaan dari distribusi Scala. Selamat mencoba!
