Re: [Pharo-users] [Pharo-project] Anyone using ImageSegment aut-save on snapshot?
by Mariano Martinez Peck June 15, 2011

June 15, 2011

I don't think so: 1) If I remember correctly, that part was broken and I fixed it some time ago. But nobody ever reported that, I found it. 2) Few people is using ImageSegment in general. In fact, I don't know anyone apart from Netstyle.net and Squeak Projects (which are not anymore in Pharo). 3) Not every users of ImageSegment use the default location of the files. I am almost sure Netstyle.net don't do that. So, if we join 1), 2) and 3), the conclusion is that I don't know anyone who is using this feature. But maybe there are.... I would remove them and, in the future, if needed, do a kind of notification for image renaming where listeners can be registered.

Re: [Pharo-users] TWM custom buttons (was: Multiple World integration)
by laurent laffont June 15, 2011

June 15, 2011

Hi Benjamin, Here's a first version where you can add your own buttons using a pragma, like this: SomeClass class>>buttonTestRunner: aBuilder <twmBarButton> aBuilder action: [TestRunner open]; help: 'open TestRunner'; icon: TestRunner taskbarIcon'. See TWMBarInANewWorldTest>>setUp and tests. Laurent.

Change an existing method from another project
by Miguel Moquillon June 14, 2011

June 14, 2011

Hi, I'm going to provide a new way to write unit tests without having prefixed test methods with the word 'test'. As I don't want to write another unit test framework, I need to change some methods of SUnit (as well of Autotest). Is there any way to do that from an external project without creating a specific fork of theses projects? Mig

Tiling Window Manager - status update
by laurent laffont June 13, 2011

June 13, 2011

First thanks to all people that send patches (and tests !!). Still not haven't merged all of them - don't hesitate to post in repository so code is not lost. Yes I will merge layout policies. Gofer it squeaksource: 'TilingWindowManager'; package: 'TWM'; load. (Smalltalk at: #StandardUITheme) beCurrent. (Smalltalk at: #TWMBar) showTWMBar:true. Tested on PharoCore 1.2 and Pharo 1.3. Now this has support for world snapshot, that means you can arrange the windows and take a snapshot of the layout. Then you can restore these layouts later. (icons camera, <, > and trash). I'm not entirely satisfied with this, thanks for feedback. In Pharo 1.3 there's initial integration with KeyMapping. To load: Gofer it squeaksource: 'ShortWays'; package: 'ConfigurationOfKeymapping'; load. (Smalltalk at: #ConfigurationOfKeymapping project version: #bleedingEdge) load. Then in settings browser > Keymappings > Tiling Window Managers you have all actions of the dock mapped. Not all shortcuts are working, don't know why, if people can test and find good shortcuts thank you. Creating a nice Metacello Configuration for TWM will be appreciated :) Cheers, Laurent Laffont - @lolgzs <http://twitter.com/#!/lolgzs> Pharo Smalltalk Screencasts: http://www.pharocasts.com/ Blog: http://magaloma.blogspot.com/ Developer group: http://cara74.seasidehosting.st

Re: [Pharo-users] Pharo on Fedora 15_64

Indeed I am running Fedora 15 64bit. But I also run Pharo on debian 5 64bit (no Problems). But your guess (or deeper knowledge), that there is (or might be) a problem with the missing 32bit libraries in Fedora 15 64bit is obviously right and helped me to make Phao running on my Fedora 15 64bit version a least. To run 32 bit software versions, the libraries it depends on must be installed. (I did not know, that Phedora is only just a 32bit system.) The method described in the link does not work for Fedora 15. There are "endless" messages of the kind - package not available. Fedora/RedHat has switched the prefered package manager from rpm to yum. Could that be the crux of the fail? I really do not know! (Certailly I checked on my system that rpm was installed properly!) Here a description of my procedure (very close to your link!) to overcome that problem, that hopefully might be helpful or other Fedora 15 (or other 64bit Linux-) users to get the 32bit libs with yum. The procedure is quite close to that given in the link you sent. To be able to get the 32bit libs, open (or in my case - create) the file /etc/rpm/macros as root and add the following line at the end of the file: %_query_all_fmt %%{name}-%%{version}-%%{release}.%%{arch} Open as root and add the line. Save the file and exit the editor. You may use any simple text editor (I used vi) and do not forget to do sudo first: sudo vi /etc/rpm/macros After that first step, you are able to install the 32-bit libraries that are required by Pharo (or other 32bit apps). The following command installs them all: sudo yum install qt.i686 qt-x11.i686 libXv.i686 libXss.i686 libXScrnSaver.i686 After that, Pharo should start properly! Or say, at least it started on my Fedora 15 64 bit. If there is something explained not clearly enough, I am willing to to state more precisely on request. My CS-horizon is very restricted - i am happy if things work without any problems. Tnx, and I wish Pharo good progress towards the 64bit version! Regards BB PS: I thank the Pharo developers for their outstanding work!

Glorp port support for Postgres native driver Was: [ANN] New Glorp Port
by Guillermo Polito June 11, 2011

June 11, 2011

Hi! I've done some little changes in order to have the native postgresql driver working in pharo 1.3 with glorp :). To download it, evaluate: (ConfigurationOfGlorpDBX project version: #stable) load: 'GlorpPostgresV2NativeWithTests' There are 998 tests (Glorp, Postgresql, Cryptography), and most of them are green. Most of the fails are from cryptography :/... I tested it in 1.3 only by now.

I was going to make a list of what we had to do to import it into pharo to send it to you :).
