Arduino package extra files
by Bernat Romagosa Nov. 15, 2013

Nov. 15, 2013

Hi list, After successfully installing the Arduino package, I noticed this Getting Started text: *After installing the Arduino packages by evaluating...* * * * ConfigurationOfArduino load.* * * *...you'll need a couple extra support files in order to be able to upload programs to your Arduino board. You can download them from here:* * * * http://www.mediafire.com/?1rep41uygl4rpf1* * * *Extract the contents of that file in the same directory where you have your Pharo image.* But the mediafire link is broken. Where can I get the extra support files? Thanks! Bernat. -- Bernat Romagosa.

CogVM arguments in Win32
by Bernat Romagosa Nov. 13, 2013

Nov. 13, 2013

Hi list! I've never used Pharo on Windows before, but we're starting to package a multi-platform app right now and I've just found out command line arguments don't work like I thought they would. I need to run the image headless, so I figured: bin-win32\Pharo -headless shared\Pharo2.0.image Would do the trick, but it's not working. Pharo /? doesn't give any hints either, and I can't seem to find the docs for the Windows VM anywhere. Does anybody know where I can find a Win32 VM reference? Thanks! -- Bernat Romagosa.

Anyone have a script to take a set of Packages and commit them in chronological order to a git repo?
by Paul DeBruicker Oct. 31, 2013

Oct. 31, 2013

Hi, I'm thinking to use travisci.org to build and test some of the MIT licensed packages I've been maintaining. I'd like to get those packages development histories into git in an orderly way, so the information is there for curiosity's sake. Thanks Paul

Strange behaviour of abstract method
by Michael Paap Oct. 31, 2013

Oct. 31, 2013

Hello list, in our OOP course we noticed some behaviour of an abstract method, which I cannot explain. Maybe you can help me: If I do the following SequenceableCollection new add: 123 I would expect an Error. The method add: is not implemented in SequenceableCollectionbut inherited from collection, where it's only statement is self subclassResponsibility But in reality, Pharo seems to enter an endless loop, consuming more and more memory. Can someone please explain to me, what happens here? Greetings, Michael

CogVM arguments in Win32
by Torsten Bergmann Oct. 30, 2013

Oct. 30, 2013

1. HEADLESS The SqueakVM had support for this and it was usable in the past <quote> -headless Tells Squeak to run without a main window. However, for allowing at least some access to Squeak, an icon is added to the system tray. If you double-click this icon, the Squeak window will show up again. </quote> Ask on the VM list - maybe the "headless" option could be fixed for Pharo VM to work again. 2. Shell_NotifyIcon route You use "apicall" pragram - so I expect you will use FFI. Note that I would not go that path because FFI its outdated and unsupported. Go the NativeBoost route - its much better! PNOTIFYICONDATA is a windows structure you would have to wrap. You could look at various examples in the "OS-Windows" package (loadable from config browser in Pharo 3.0) to get some examples of wrapped structures. I'm not sure if "Shell_NotifyIcon" is the right way - if I remember correctly from my C/C++ and SmalltalkMT times it is just used to work with the tray icons. These will usally have a menu (so you need callbacks) and the window is just invisible (receiving no events, ...) while the process is running. Note that you have to dive down into the darkness of Win API before you get enlightened here ;) Bye T.
