MalNode that store their neighbors nodes
by Serge Stinckwich
Hi all,
I'm using MalGraphAlgorithm to build simulations of disease propagation on
random network and for performance reason, I need to store inside each
nodes of my network, the neigbours nodes.
I see a class MalNodeWithNext that store next edges, is it the class I
should use for my nodes ?
I see a trait called #MalTEdgeNode, is it related ? how it works ?
Thank you.
Regards,

Zeroconf to execute playground in a pre-made image (winddows 10)?
by Cris Fuhrman
Hello all,
I have a playground script that will analyze the first MSE model and
produces output in a CSV file.
I would now like to be able automate this, and I think Tudor Girba gave me
a hint of using Zeroconf.
So far I have not been able to get it to work under Windows 10. The curl
command works to get the image from get.pharo.org, curl get.pharo.org |
bash
However, the following attempts don't result in errors, but I don't get any
useful output either:
$ bash ./pharo Pharo.image --help
$ ./pharo Pharo.image --help
$ pharo-vm/PharoConsole.exe --headless Pharo.image --version
Does it work in Windows 10? I've tried in Git Bash and CMD.exe (the last
command, since the bash commands don't work).
Cheers,
C. Fuhrman

Generating GTInspector extension screenshots?
by Luke Gorrie
I have built an application based on the GTInspector. Hurray!
Now I want to share it and I need to write documentation. I would like to
include screenshots in the docs but I don't want to create them by hand.
So my question is: Is there an easy way to automatically generate
screenshots for GTInspector extension methods? e.g. to specify an object
and the name of a presentation and to get a PNG file of how that looks in
the GTInspector.
Thanks!
P.S. References to how other people write their docs in general would be
interesting.
P.P.S. Here is GTInspector browsing internal data structures of a JIT
compiler :-)

[ann] moldable brick editor - alpha
by Tudor Girba
Hi,
We are very happy to announce the alpha version of a moldable editor built in Brick (https://github.com/pharo-graphics/Brick) which is based on Bloc (https://github.com/pharo-graphics/Bloc). This is primarily the work of Alex Syrel. The project was initially financially sponsored by ESUG and it is currently supported by feenk. And of course, the project is based on the tremendous work that went into Bloc and Brick by all contributors.
Take a look at this 2 min video:
https://www.youtube.com/watch?v=2vy6VMJM9W4&feature=youtu.be
The basic editor works and it is both flexible and scalable. For example, the last example shown in the video is an editor opened on 1M characters, which is reasonably large, and as can be seen see one can interact with it as smoothly as with the one screen text. It actually works just as fine with 100M characters.
The functionality of the editor includes: rendering, line wrapping, keypress and shortcut handling, navigation, selection and text styling. Currently, the editor is 1260 lines of code including method and class comments. This is not large for a text editor and this is possible because most of the work is done by generic concepts that already exist in Bloc such as layouts and text measurements. Beside the small maintenance cost, the benefit is that we have the option to build all sorts of variations with little effort. That is why we call this a moldable text editor.
Another benefit of using elements and layouts is that we can also embed other kinds of non-text elements with little effort (such as pictures), and obtain a rich and live text editor. We already have basic examples for this behavior, and we will focus more in the next period on this area.
The next immediate step is to add syntax highlighting. Beside the text attributes problem, this issue will also exercise the thread-safety the implementation is. The underlying structure (https://en.wikipedia.org/wiki/Rope_(data_structure)) is theoretically thread-safe, but it still needs to be proven in practice.
We think this is a significant step because the editor was the main piece missing in Brick and it will finally allow us to build value that can be directly perceived by regular users on top of Brick and this, in turn, will generate more traction. Please also note that because now Bloc is directly embeddable in Morphic it means that we can actually start using it right away. For example, the picture below shows the text element being shown through a live preview in the GTInspector.
This is another puzzle piece towards the final goal of engineering the future of the Pharo user interface. There is still a long way to go to reach that goal, but considering the work that is behind us, that goal that looked so illusive when Alain and Stef initiated the Bloc project is now palpable.
We will continue the work on this over the next period and we expect to announce new developments soon.
If you want to play with it, you can load the code like this (works in both Pharo 6 and 7):
Iceberg enableMetacelloIntegration: true.
Metacello new
baseline: 'Brick';
repository: 'github://pharo-graphics/Brick/src';
load: #development
Please let us know what you think.
Cheers,
Alex and Doru
