Multiexpr

[jmgimeno]

Now Eval evaluates all the selected sexprs.

• If the last sexpr in selection is malformed, it throws the exception and does not evaluate any of them.
• It shows the evaluation of each sexpr in a window (first the form, next the value).
• If the evaluation of a sexpr throws an exception, shows the exception instead of the value, but continues the evaluation of the rest of expressions.

I would actually prefer that this follow SLIME behavior.

• If the last sexpr is malformed, throw an exception.
• Show only the value of the last expr evaluated.
• do not continue evaluation of the remaining expressions.

Would you mind making these changes and sending me another pull request.

Many thanks.

Just to clarify:

• If selection is "(def a 2) (def b 1) (+ a" an exception is shown and no evaluation takes place.

• If selection is "(def a 2) (def b 1) (+ a b)" all expressions are evaluated and we only show the evaluation of the last one, that is, we show:

  Form:
     (+ a b)
  Result:
     3 

• If selection is "(def a 2) (throw (Excepcion.)) (def b 1)" we evaluate the first and second expressions but not the third, and we show:

  Form:
      (throw (Exception.))
  Exception:
      ugly-trace

Thanks.

I've done a path that behaves as in my previous comment.
