class ILoop extends LoopCommands

The Scala interactive shell. This part provides the user interface, with evaluation and auto-complete handled by IMain.

There should be no direct dependency of this code on the compiler; it should all go through the intp reference to the interpreter, or maybe eventually even over the wire to a remote compiler.

    Adds jar file to the current classpath.

    Adds jar file to the current classpath. Jar will only be added if it does not contain classes that already exist on the current classpath.

    Importantly, require adds jars to the classpath without resetting the state of the interpreter. This is in contrast to replay which can be used to add jars to the classpath and which creates a new instance of the interpreter and replays all interpreter expressions.

  77. def reset(): Unit

    reset the interpreter in an attempt to start fresh. Supplying settings creates a new compiler.
