The code is actually mostly the work of SÃ©verin Lemaignan, so if we want to integrate his code in Pharo, we should ask him to sign the Pharo licence agreement: http://code.google.com/p/pharo/wiki/ListOfOkCommitters This code is already included in the last version of Squeak. I dunno about the scratch version. This is different from the Squeak version ?

Serial Port
by Joan GÃ¼ell Jan. 27, 2011

Jan. 27, 2011

Hello We are developing software to interact with small robots for educational purposes. To do this we need to use the serial port. SerialPort class that includes Pharo does not work on mac or linux, because itÂ´s not able to open ports by name. It would be interesting that future versions include a SerialPort that would work in these circumstances. we are using since a time aÂ´go the plugin that comes with Scratch, with this we just copy the plugins in the folder of the VM, the Plugin that comes with the VM Scrath, and add to the image of the image classes of Scratch , ScratchPlugin and SerialPort2.Up to date this has worked on all VM including the latest Cog. It works on Linux, Mac or Windows.We wory that future versions will lose support. The source code for the plugins can be found on: http://info.scratch.mit.edu/Source_Code ScratchPluginSrc1.4.zip Joan GÃ¼ell jguell(a)e-citilab.eu Joan GÃ¼ell jguell(a)e-citilab.eu

TestMock v-9 published; now works with Pharo 1.1.1
by Anindya Haldar Jan. 26, 2011

Jan. 26, 2011

Dear Smalltalkers, I am glad to make an updated version (v9) of the mocking framework TestMock available with added Pharo 1.1.1 support. Previously reported v8 issues arising from the deprecation of KeyedSet and some other changes with TestCase and Boolean classes in Pharo 1.1.1 have been fixed. This version continues to work with Pharo 1.0 and Seaside-2.8 dev images as before. Here is the link to the project: http://www.squeaksource.com/TestMock.html Happy smalltalking! Regards, - Anindya Haldar

Minimal pharo
by Annick Fron Jan. 25, 2011

Jan. 25, 2011

Hi all, I have now tried the minimal images indicated by Torsten and Stephane, on Windows it amounts to 9.1 Mega in memory ... Would it be smaller on Linux ? Yet, I still need a shoe horn, having only 8 M ram from which 1.5 is already taken by the kernel... Any idea to downsize even more ? Best regards Annick Fron

Hello, I recently saw the article Multiple Worlds for Pharo <http://seandenigris.com/blog/?p=767>, and I tried loading it from PharoInbox, but got the following Warning. ------------------------------------------------------------ This package depends on the following classes: GLMUITheme You must resolve these dependencies before you will be able to load these definitions: GLMOrangeUITheme GLMOrangeUITheme classSide>>baseSelectionColor GLMOrangeUITheme classSide>>lightSelectionColor GLMOrangeUITheme classSide>>setDejaVuFontsLarge GLMOrangeUITheme classSide>>setDejaVuFontsSmall GLMOrangeUITheme classSide>>themeName GLMOrangeUITheme classSide>>veryLightSelectionColor GLMOrangeUITheme>>buttonMouseOverFillStyleFor: GLMOrangeUITheme>>buttonSelectedFillStyleFor: GLMOrangeUITheme>>buttonSelectedMouseOverFillStyleFor: GLMOrangeUITheme>>configureWindowBorderFor: GLMOrangeUITheme>>configureWindowDropShadowFor: GLMOrangeUITheme>>controlButtonMouseOverFillStyleFor: GLMOrangeUITheme>>controlButtonNormalFillStyleFor: GLMOrangeUITheme>>dialogWindowPreferredCornerStyleFor: GLMOrangeUITheme>>glamorousBaseSelectionColorFor: GLMOrangeUITheme>>listNormalBorderStyleFor: GLMOrangeUITheme>>menuItemSelectedFillStyleFor: GLMOrangeUITheme>>scrollPaneDisabledBorderStyleFor: GLMOrangeUITheme>>scrollPaneNormalBorderStyleFor: GLMOrangeUITheme>>selectionBarColor GLMOrangeUITheme>>selectionColor Select Proceed to continue, or close this window to cancel the operation. ------------------------------------------------------------ I can't figure out what package I need to load first to resolve this dependency.

Infinite loop is not stopped by Cmd+.
by Alex Schenkman Jan. 24, 2011

Jan. 24, 2011

Hi List, Recently I had a bug causing an infinite loop, which in turn hanged the image. I thought that Cmd+. would allow me to stop this, but this is not the case. Adding and executing this method hangs my image and Cmd+. does not stop it. MyClass>>infinite ^self infinite Is this the right behavior? Thanks in advance!

Error in logging chapter of "Pharo collaborActive Book"
by Panu Suominen Jan. 22, 2011

Jan. 22, 2011

I was not sure if this is the right list. There is example like this in logging chapter of the Pharo book: Gofer new project: 'Logging'; package: 'ProcessSpecific'; package: 'Logging'; load It does not work. Maybe it should be: Gofer new squeaksource: 'Logging'; package: 'ProcessSpecific'; package: 'Logging'; load -- Panu

Pharo on Windows
by Andrew Black Jan. 22, 2011

Jan. 22, 2011

I just started using Pharo on windows for the first time. First, I should say that I'm really impressed. Pharo seems much more solid than when I last tried it. I programmed all day without getting a walkback! All of the tools "just worked". Well done! It's a lot of work creating a solid user experience, but you have done it. Now I have some Windows-specific questions. I'm a real windows newbi, so please be patient. After I downloaded Pharo.app, I dragged the whole directory to a convenient place, and tried to launch the Pharo.lnk file, just like the readme file says. But there is no such file visible in windows explorer (even though I have "don't show extensions for known file types" box unchecked. The file shows up as Pharo. Anyway, I figured that it was really Pharo.lnk (Cygwin tells the truth) and double-clicked on it. This brings up an alert that says C:\Users\<username>\Desktop\OneClick.app\Contents\Windows\Squeak.exe the specified path does not exist. Is this because I moved the downloaded package? Shouldn't the symlink be relative? Anyway, I looked in ...\ Contents\Windows\, double-clicked on Squeak.exe, and everything started up just fine. I worked all day, and saved my image a few times using the Save menu on the desktop. Each time, I get the usual confirmatory dialog in the Transcript. Overnight, my machine shut down. Today, I relaunch Squeak.exe, and of course I get the virgin image! Where is the image that I've been using? The Windows "search this computer" tool can't find it! What about my package cache? Eventually I find everything in Pharo.app\Contents\Resources, but not until I've had a few moments of panic! Questions: Is this the appropriate behaviour on Windows, or was there a user error on my part? Is it OK to move my image somewhere else? How can I change the current directory for Pharo on Windows? OK, so now that I've found my image file, how to I re-launch it? I double-clicked on the .image file, and I got a dialog saying that Windows didn't know what program to use to open it. Fair enough. So I told it to use Squeak.exe. Pharo launches, and I get: "Error: invalid utf8 input detected". It's treating the image as if it were a source file: it has opened a MultiByteFileSTream on it. That's not right. How do I re-launch my Pharo image? Andrew

Where do I find KeyedSet?
by Alex Schenkman Jan. 22, 2011

Jan. 22, 2011

Hi List, I'm trying to use the TestMock package in a Pharo-1.1.1-OneClick image, and it uses KeyedSet. Where can I find this class? Is there any tool to lookup which package in SqueakSource contains a specific class? Thanks in advance!
