Scaladoc from the scala interpreter

Question

I've been experimenting with Scala lately and I noticed that when I need to look up a function or a class, I have to go to the website or navigate to the local documentation.

Is there a way to read the Scaladoc from inside the interpreter?

Maybe something like help() in Python.

Answer 1

Scalaex is a cool Scala-web documentation like Hoogle with an usefull CLI-client.

(But it's not inside the interpreter. Unfortunately I cannot write a comment to your question, so I write this as an answer.)

Answer 2

I'm running the command line scala interpreter for 2.9, and tab-key completion works for me:

val x = List(1,2,3)

x. 

Then press TAB

Shows the list of methods.

Not quite full docs, but helpful nonetheless.
