[lively-kernel] Loading JS files into world

Hi, Marko!

Thanks for your help. The second method you described of adding it to my
user config worked.

As for the first method (which, as you point out, is what I actually want
to use so that the
worlds I create are usable by other users), I have a problem.

When I right click in the module list I just get the morphic halo (the same
thing I get when I Ctrl+Left-Click).
If I select the menu from the halo, I cannot see an option to either "add
to world requirements" or "add new file".
How can I configure Lively to show the context menu when right clicking? Or
what other key combination can
I use to see the context menu?

By going over the Lively-101 again, I can see there that Right click should
be
"ignored (some morphs provide a menu on right click)"
 but it's not ignored in my system. Is that makes any difference, I'm on
Linux.

By the way, I'm using lively for doing presentation slides that require
showing JavaScript code.
I've already created one about web messaging. I'm trying to clean it up so
that I can share it on lively-web.org.

The great thing about lively for this use case is that I can create a slide
that embeds some code
that I can run while doing the presentation; and then I can show the code.
It's great.

I'm using the PresentationController part. I saw the Lively2Lively world
from Robert's presentation
(http://lively-web.org/users/robertkrahn/2013-08-17_Lively2Lively.html)
and knew that I want to use that.

I'm very new to Lively, but not to Morphic. I've spent some time in 2004
playing with Squeak and reading up on
Smalltalk. I still have Squeak installed, and boot it up from time to time.

I even played with the original Morphic, in Self, just to see it in the
environment where it was invented.
It's very cool.

Funny that Morphic ends up in a language with a heavy inspiration from Self
(the prototypes, at least)
even though everyone wants classes instead; even Morphic implementation, it
seems,
with it's Object.subclass, etc. :D

Thanks again.
