Screencast proposition: Watch someone read code.
by Helene Bilbo Jan. 29, 2011

Jan. 29, 2011

Hi, i have a proposition for a Pharo-Screencast: I would love to look over someoneâs shoulder while she/he is *reading* code. A possible plot would be to download something from squeaksource and then trying to make sense out of it - and talking while doing so. (It would also be good to see all the relevant functions of the browser in action). Background: While i have read some books now (blue book, pharo by example, seaside by example, best practice patterns) i have never actually seen people programming. So i absolutely miss the craftsmanship side of things. Anyway thank you for Pharocasts. Best regards, Helene. -- View this message in context: http://forum.world.st/Screencast-proposition-Watch-someone-read-code-tp3244… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Making a .st file from the source of a method
by Sean P. DeNigris Jan. 29, 2011

Jan. 29, 2011

I have a class that I use to set up my images. A subclass has a method: setupScript (Smalltalk at: #UpdateStreamer) new updateFromServer. "Do other stuff..." I want to save the statements of the method above in a .st file to pass as an argument to the vm. That's all working, but in order to retrieve the two statements above, I do: setupScriptContents | scriptMethod sourceString sourceStringWithBracketsStripped | scriptMethod := PharoTrunkImage compiledMethodAt: #setupScript. sourceString := scriptMethod methodNode body asString. sourceStringWithBracketsStripped := sourceString copyFrom: 3 to: sourceString size - 2. ^ sourceStringWithBracketsStripped. That works, but I don't like it. What's the best way to do this (or is this it)? Thanks.

Polymorph example
by laurent laffont Jan. 28, 2011

Jan. 28, 2011

Hi, I've written a tiny little application to prepare a screencast on Polymorph / GUI. As I'm far from being expert on this, can someone check that it is done "the right way" (especially on how to manage OK/Cancel ) ? Gofer it squeaksource: 'LaurentLSandbox'; package: 'AddressBook'; load. (Smalltalk at:#ContactListEditor) open. Thanks.

Downloading a JPEG
by Sean P. DeNigris Jan. 28, 2011

Jan. 28, 2011

Is there a way to save a JPEG from the web to a file in Pharo? I can open it as a Form, but I also want a copy of the original saved. Thanks.

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

Multiple Worlds for Pharo *stable*

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. I'm using Pharo 1.1.1 Latest update: #11414. Can anyone help me out here? I really don't want to use unstable just to get this one feature. Thanks, Aidan
