The last exception that was thrown in the REPL; null if nothing has
yet been thrown.
The last exception that was thrown in the REPL; null if nothing has
yet been thrown. Useful if you want additional information from the
thrown exception than the printed stack trace (e.g. many exceptions have
additional metadata attached) or if you want to show the stack trace
on an exception that doesn't normally print it (e.g. seeing the stack
when a Ctrl-C interrupt happened) via lastException.printStackTrace.

Frames get pushed on a stack; by default, a saved frame is
accessible simply by calling load. If you provide a name
when saveing a checkpoint, it can later be loaded directly
by providing the same name to load
Un-named checkpoints are garbage collected, together with their
classloader and associated data, when they are no longer accessible
due to restore. Named checkpoints are kept forever; call delete
on them if you really want them to go away.
Lets you configure the pretty-printing of a value.

If class wrapping is enabled, this lists the names of the previous commands that the current commands actually references (as told by the scalac).

E.g. in a session like
@ val n = 2
n: Int = 2
@ val p = 1 p: Int = 1
@ n + p
res2: Int = 3
this would have returned an empty list if called from the same line as val n = 2. This would have returned Seq("cmd0", "cmd1") if called
from the same line as n + p, as both cmd0, that defines n, and cmd1, that
defines p, are referenced from this line.
