[lively-kernel] Hiding Connection Sources

[Sean P. DeNigris]

I went through Dan's server load example, and when I was done, I deleted the
clock. I figured if I was really going to publish the app, I wouldn't want
the command line and clock floating around, just the graph. However, when I
deleted the clock, the script stopped ticking. I finally added the clock and
shrunken command line as submorphs of the graph window and made them
invisible. But it seemed like a hack e.g. halos could still be brought up on
the invisible morphs. What would the "right way" be?

Also, I found it difficult to find the Morph class in the Browser so that I
could find out how to make them invisible. I didn't see a search facility,
so I hunted around the directory structure until I found it. I even tried
cmd+b in a workspace but that didn't seem to work. If I know the name of a
class, how best to bring up a browser on it?

Thanks!

You can search for definitions using Cmd+Shift+f. When you have an object and want to see what it can do, you can also type a dot and press Cmd+Shift+p to open an autocompletion morph.


The World menu has a Documentation->On Shortcuts item that might be helpful.


cheers,

Tim

Thanks :) That's probably not a great choice. On Mac in Chrome, if the mouse
focus is not in the right place, it makes Chrome fullscreen :/

That seems to open a method finder. How do I open a class browser on a
particular class when I don't know where it lives?

Cmd+Shift+F opens a search window with senders (if you had a selection and were not asked for a search string) - tab is prefixed with "S:" - or with senders and implementors (if you were asked for a search string) - tab prefixed with "SI:".
You can browse (most) senders and implementors with the Source Code Browser using the "browse" button in the search window.

These all seem to be about methods… I want to search for a *Class*

The search can also be used to search for a class an browse it (yet it does not seem intuitive): Try for example "Rectangle" and you will get a list of Rectangle references.
Close to the top of this list, there is an entry "global name: ..." - that is the one you are looking for. When you click on "browse" a System Code Browser will open and show the "Rectangle" class and its location in the system to you.
Sorry that this is not easy/intuitive.

I went through Dan's server load example, and when I was done..., when I
deleted the clock, the script stopped ticking

After playing some more, I can see that obviously, if the step mechanism is
driving the action, then the clock has to be in the world. But the command
line can be closed without stopping the chart updating.

But this brings up another interesting implication of relying on Morphs
being in the world… the ElProfesor tutorial recommends accessing morphs via
this.get() or $morph(). However, this creates duplication everywhere
assuming that the Morph will be forever reachable that way. If the Morph
needs to be removed from the world, that will all break. Would it be better
to abstract at least the top-level application object as a property accessed
via $world.getWhatever()
