What you are seeing is the World - empty until you fill it up with objects. If
you scroll down the page, you will see the Navigator flap along the bottom
left corner, Click on "Escape Browser" to switch to full screen mode. The
default language is Deutsche. Use the "World" button in Navigator to change
the language.

Have fun,

Close to/After the beginning of 2008 it might be a good time for an
(ugly) but fun hack! ;)

The project can be loaded into a 3.9 image.

http://www.lazarevic.de/download/squeak/fireworks.002.pr

This should also work, but no guaranties...

http://squeakland.org/project.jsp?http://www.lazarevic.de/download/squeak/fireworks.002.pr

Cheers (in every sense),
  Alex :D

PS: This is the result of some fun hours of hacking, but shouldn't be
looked at closely! After all this should be much nicer in kedama!
PPS: Use Alt-. to stop it

Hello all, and happy new year,

There are three Logging packages for Squeak that I know of.

1. SimpleLog
2. Toothpick
3. LogEngine
there is also a Null logger.

This package "Logging", available from SqueakMap and in Universes, is
slightly higher level 'front end' api to these logging back ends.

best regards

Keith

===================
from the class comment

Convenient usage: 'annotated values'

self log x: 10 y: 20 z: 30.

To select a specific log severity level (i.e. not the temporary one
featured above).

self log info x: 10 y: 20 z: 30.

To log the current method's input parameters.

Rectangle-#corner: topLeftPoint extent: heightWidthPoint

self log debug this.

would be the same as

self log corner: topLeftPoint extent: heightWidthPoint.

To log the current methods variables:

self log debug vars instance.

I forgot to mention the new news, that being support for Göran's
SimpleLog has been added recently.
Toothpick is also supported, though LogEngine does not have an adaptor
as yet.

best regards

Keith

p.s. if the authors of toothpick happen to read this, I still think some
additional work is needed for Toothpick to support logging to a file
reliably on windows.

AddMiorph causes VM coma?

Hi Blake,

It looks like your son found a good one.*  Can he do
it again?
And can you explain how to reproduce the error?

I tried it and failed to get stopped. Which is not
surprising.

What I did was:
(In a fresh squeak 3.10  version 7159, opened with  a
mac classic vm 3.8.9beta7)

Dropped a .gif file on the image (which gave me a
sketch morph)

Opened a workspace (Worldmenu>open>workspace) and
from the menu in the title bar set
 create textual references to dropped morphs to true

then I dropped the sketch onto the workspace (which
created a textual reference to the morph in my case
sketch3255)
wrote, selected and did a "print it" on
'World addMorph: sketch3255' .

This caused me no problems.

I then deleted the sketch; reselected the phrase and
did it again.

Still no problems.

-----
What did your son do different? Can you supply a
report similar in detail to the above?
If you can show how to reproduce the problem then
someone may be able to help you track down the
trouble.

Yours in curiosity and service,

Jerome Peace

I never coded for X server, so i don't know what can cause problems,
but i'm sure that proper fix should work regardless of display bpp.

Sorry I can not reproduce this. It shows me several jbj versions in
non-filtered and filtered [1] mode. In the latest tab I
see ICal-jbj.67.mcz.

Thanks, Brian.

I notice it says several demos are included but I don't see any.

Dunno if you ever got much feedback but I'll tell you what we think once
we figure it out.<s>

The demos are in some class side methods, IIRC :)

It's been a while, and I published it, but a different developer here
wrote it.

 Ah, you are right.  the code wasn't the way I remember it should be.
Latin1Environment (which should be called WesternEuropeanEnvironment)
flieNameConverterClass should be a bit more elaborated (or just
returning UTF8TextConverter).
