Use a pager to display documentation when executing help() in the REPL

[illume]

• What you were trying to do,
  help(turtle)

• What you expected to happen,

To see the top of the help.

• What actually happened,

A very long time to print the help text in the non python repl. In the ipython repl it showed the bottom of the text.

• Why this difference is problematic (it may not be a bug!),

Instead of seeing the top of the help you see the bottom of it. Because you need to scroll to begin reading the help.

So your creating a script consisting of

import turtle

help(turtle)

... and running it?

[illume]

No. In the repl.

In the repl

I'm confused? Perhaps a screenshot?

[illume]

Go into either of the repl in Mu (there are two different ones in Mu, one using ipython). import turtle. help(turtle) Now compare the behavior to a different python repl. The standard python in a terminal(cmd prompt) shows the top of the help, and uses a pager (less). Mu shows the bottom of the help. Hope that helps. That’s all I got. Have a nice day.

I will update the title of this issue to include the mention of a pager, I guess that will clear up some confusion.

For anyone who hasn't tried it, running help(turtle) prints 8000 lines of documentation. Hardly useful as it is.
