Hello,
The 4 & 5 of April there is the free software event at Lyon[1].
I am planing for a DrGeo presentation.
It will be cool to present Pharo too. The thematic of this event is

The Pharo way is Fuel, it will let you persist a tree of object. The package
is present in Pharo by default. Easy and fast. It is documented in one of
the Pharo book.

Thanks for the tips.
So far, I've found two ways to write the datagram. One with stream, the
other one with hexadecimal representation.

Torsten, Offray, Trygve,
Thanks for your suggestions for long term thinking.
In the meantime I need a workable solution for the coming weeks, I found the
safer is to instruct the students how to operate with Playground to not lost
their scripts.
We design our teaching unit around one example
Hi,
Do we have an external workspace with a deterministic save feature.
I looked at the catalog but found none,
Both Workspace and Playground fall short.
Workspace save file with 0 byte of content!
Playground, with my experience with student, is absolutely not reliable to

Thanks Sven, it works.

Hello,
I want to fill a byte array, but this code does not work:
| packet |
packet := ByteArray streamContents: [:str |

It worked.
However when closing the windows, there is an error:

Hello,
Thanks for the tip.
Yep, indeed it is possible to get the information from the command line. But
I need a strategy that will work on Windows too (75% of the Dr. Geo user
base).
I have the same problem with bitmap clipboard, I have a strategy only for
linux with command line[1], may be for
Of course I meant Ctrl-Right, the preview on .st. script is then empty.
Or do I have the preview unactivated?
Try out the built I proivde a link to, it now works on Mac OSX too :)
Thanks
