So as Ben said I am the author of Ephestos, a communication bridge between Blender and Pharo . To go directly to the how to . Ephestos is basically a socket bridge that send via sockets strings from pharo to python that then python executes as python commands. Ephestos is made so it works inside blender but I promised Atals a spin off project that allows the same socket bridge to be used as a standalone. To use do the following. 1) Get Ephestos , you can find it and install it with the configuration browser in your image in Pharo 3 and Pharo 4. Make sure you have a recent release though because I added it recently. 2) Get pyAtlas , this is the python side , you can get it from here --> https://github.com/kilon/pyAtlas 3) in your command line cd to the pyAtlas directory and execute : python3 pyAtlas.py 4) in Pharo you can now try any python code you want for example Ephestos sendMessage: 'print("hello world")'. Ephestos sendMessage: 'x = 3'. x := Ephestos getValue: 'x'. x inspect. Ephestos sendMessage: string, basically sends the python command to be executes while getValue: sends the command and returns a value as a string. you can use string 'exit' to close the socket bridge but this part is buggy as it seems to keep the binding of the sokcet active and I have to wait to clean it up in macos to reopen the bridge. You can also use pharo syntax and python errors will trigger the pharo debugger with a title the python error itself. You can find more information about Ephestos in my gitbook that can be read here https://www.gitbook.io/book/kilon/ephestos Also I forgot to add that sendMessage can send multiline strings , so its possible to send python class definitions and other stuff, you type the string exactly as you would type python code respecting whitespaces. If you want to execute loads of lines of python code then it would be better to put your code in a python module and do Ephestos sendMessage: 'import mymodule' assuming your module is called 'mymodule' , python import basically are executions of code. If you have any questions just ask. Bare in mind this is a socket bridge so its not ideal for sending thousands of messages per second and you may run into the occasional bug or two which I will fix if you report it. Nonetheless it should allow you to execute any kind of code and not just call python functions or python methods.

Not much of a script as such. Put your Pharo image, changes and sources files in your home directory. create/edit a file called .xinitrc containing only "exec pharo-vm-x" (without quotes) within your home directory. Start the X session by issuing "startx" at the command line, and the GUI should be up with Pharo as the only application, no need for even a window manager. Next, just set the Pharo session to use full-screen mode by bringing up the "World" menu inside Pharo, go to the "Windows" sub-menu, and choose "Toggle Full Screen mode", and voila, you have a Pharo full-screen session, as if it's your GUI, remember to save the changes when you quit the Pharo session (which will drop you back to your *nix shell). The next time you issue "startx" within your home directory, the GUI presented would be Pharo. :) Still working on making Pharo the only shell running directly atop the Linux kernel with X as the windowing system, yeah, tried Linux FB, failed.

Gettext with pharo 3 and seaside 3.1.2
by Peter Schorsch Sept. 25, 2014

Sept. 25, 2014

Hi, Just started with pharo and seaside. Now I want to write an example seaside-application but with a multi lingual interface. So I installed pharo3 and then seaside via configuration browser. But then I had to realize that the seaside-gettext package was not installed; and also no gettext package. I found a gettext package in the repository http://smalltalkhub.com/mc/PharoExtras/Gettext. I installed the package ConfigurationOfGettext, but the configuraitonof-browser does not show it. So I installed the package Gettext via monticello. Then I found the seaside-gettext packages in the repository http://smalltalkhub.com/mc/Seaside/Seaside30Addons and installed via monticello the packages Seaside-Gettext-Core and Seaside-Gettext-Examples. Then I open a webbrowser to watch the gettext example. But there I only see: fontsize * locale * locale * locale * locale * locale That looks for me like gettext is not working with pharo3 and seaside 3.1.2 Any help is welcome - best a mini howto for gettext with pharo3 and seaside 3.1.2 Thanks in advance

Packaging Pharo for many distributions at once
by Damien Cassou Sept. 25, 2014

Sept. 25, 2014

Hi, I've packaged Pharo VM for the Nix package manager which can be installed on many Unix (e.g., Linux, MacOS X and FreeBSD). This works well but requires installing Nix on your Unix. Another solution is http://openbuildservice.org. Is any of you interested in trying to use this service to build Pharo VM packages for several Linux distributions automatically? I can help.

Dear All, AgileVisualization.com , the book about Roassal, has been updated with a new chapter. The HTML versions of the chapter are also online. Agile Visualization is written using Pillar and Skeleton. Thanks Damien Cassou and Yuriy Tymchuk (Uko) for these wonderful frameworks. I am also looking for contributors. I know that some of you guys have done wonderful things with Roassal. Sharing your knowledge with the rest of us would be fantastic. You may even get paid to write a chapter :-) Get in touch with me for more info.

Ring package, when to use it?
by Juraj Kubelka Sept. 24, 2014

Sept. 24, 2014

Hi! I am trying to understand in what scenarios is good to use Ring package instead of objects of compiled methods, classes and r-packages. It is not clear to me. For example if I want to ask for where a method/class/package is referenced should I consider the Ring package? When I should consider to use Ring? Thank you a lot, Juraj

[ANN] I stop maintaining the Ubuntu packages
by Damien Cassou Sept. 24, 2014

Sept. 24, 2014

Dear all, I've recently switched my Linux distribution from Ubuntu to NixOS. This means I can no longer maintain the Ubuntu packages and their PPA (https://launchpad.net/~pharo/) These packages need a maintainer! The good side of it is that it is not a lot of work as I did all the automating infrastructure: https://github.com/pharo-project/pharo-ubuntu. Basically, the maintainer will have to launch a few shell scripts regularly (once a month for example). I will obviously be available to help the new maintainer. The community needs *you*. Good news is: I packaged the Pharo VM for the Nix package manager which can be installed on many Unix (e.g., Linux, MacOS X, FreeBSD). And NixOS will have the Pharo VM package in its next release in October! -- Damien Cassou http://damiencassou.seasidehosting.st "Success is the ability to go from one failure to another without losing enthusiasm."

Mac VM - developer unidentified
by Usman Bhatti Sept. 24, 2014

Sept. 24, 2014

Hi, Today I downloaded Pharo vm from pharo.org. When I try to open the VM I get this security notification from Mac and it didn't happen with earlier versions of Pharo VM. I'm running: OS X 10.9.4 (13E28). [image: Inline image 1] I should be able to change my security settings to run it but I prefer not to and for less knowledgable it can be a negative message. regards, usman
