[Pharo-project] Serialization of font object
by nullPointer April 25, 2010

April 25, 2010

Regards I see in Pharo a few ways for create a font, StrikeFont, LogicalFont... I need generate dinamically code in Smalltalk for build UIs, and my problem now is when I have serialize the font of a widget. Which could be the best way for do that? In other objects like arrays, points, associations is possible get that calling #printString method. Exists some equivalence for that in fonts, or is needed implement that mechanism of zero? Thanks for answers -- View this message in context: http://forum.world.st/Serialization-of-font-object-tp2062241p2062241.html Sent from the Pharo Smalltalk mailing list archive at Nabble.com.

If some people are interested ... Cheers, Laurent Laffont ---------- Forwarded message ---------- From: laurent laffont <laurent.laffont(a)gmail.com> Date: Tue, Apr 20, 2010 at 10:16 PM Subject: Easy SqueakVM build To: Squeak Virtual Machine Development Discussion < vm-dev(a)lists.squeakfoundation.org> Hi, I've written a script to build the squeak vm from scratch on Linux in one command. It's here http://github.com/lolgzs/easy_squeakvm To build the VM, just get the the script and ./easy_squeakvm.sh This will - checkout squeakvm sources from svn repository - download PharoCore image - load VMMaker into PharoCore - generate the interpreter - build the VM - put binaries in out/squeakvm, ready to use I was tired of typing the same commands over and over :) Cheers, Laurent Laffont

[Pharo-project] #findString:startingAt:caseSensitive: broken
by Lukas Renggli April 25, 2010

April 25, 2010

The method #findString:startingAt:caseSensitive: seems to be quite broken. This is sort of a critical bug, because the widely used #includesSubstring:caseSensitive: (in Pier and Seaside) depends on it. http://code.google.com/p/pharo/issues/detail?id=2353 First, the method #findString:startingAt:caseSensitive: has all kinds of strange comments and warning from a unfinished implementation. Furthermore -- and this is the bug I am encountering -- it replaces the string to be searched with an empty WideString if either the search or the searched string are WideString instances. Thus in the case any of the participating strings is a WideString the code never finds a match. WideString new findSubstring: key in: self startingAt: start matchTable: CaseInsensitiveOrder In addition, when used in combination with #includesSubstring:caseSensitive: the code raises a "subscript is out of bounds" exception, because the start index points to an different string than the empty one the search is actually performed on.

[Pharo-project] saving headless image on Mac
by Tudor Girba April 25, 2010

April 25, 2010

Hi, I am trying to integrate a Pharo image into a continuous integration system through the command line. For that I need to spawn the image, do something, save and quit. The problem is that on Mac (using 4.2.2beta1U), when I open the resulting image I get a very tiny window instead of the original size. The command below reveals the problem (save-and-quite-image.st is attached): /Applications/Squeak4.2.2beta1U/Squeak\ 4.2.2beta1U.app/Contents/MacOS/ Squeak\ VM\ Opt -headless Pharo-1.0.image THE_PATH/save-and-quit- image.st Could anyone advise me how to proceed to get around this problem? Cheers, Doru -- www.tudorgirba.com "Every thing has its own flow."

[Pharo-project] Expectation for readFrom:... getting bored to fix bugs.

Hi What are the expectation for DateAndTime>>readFrom? On squeak such tests do not pass. testReadFromFoolProofExtension "Convenient extension without a time, only a date" "self debug: #testReadFromFoolProofExtension" self assert: ('2008' asDateAndTime printString = '2008-01-01T00:00:00+00:00'). self assert: ('2008-08' asDateAndTime printString = '2008-08-01T00:00:00+00:00'). self assert: ('2006-08-28' asDateAndTime printString = '2006-08-28T00:00:00+00:00').

So for DateAndTime we coudl have fuzzyReadFrom: aStream or something like that. Duration ====================================================== Now for Duration readFrom: the pattern is strictly followed "Formatted as per ANSI 5.8.2.16: [-]D:HH:MM:SS[.S]" In pharo it was bogus. So I was considering the one of Squeak, which looks cleaner.

[Pharo-project] starting to think about 1.1 freeze
by StÃ©phane Ducasse April 25, 2010

April 25, 2010

Hi we started with the guys here to look at the tests that fail in 1.1. We started to fix some of them. Now I would like to have a roadmap for freezing 1.1 - Green tests. - No Preferences. - What are the key other things that we want to get done in 1.1? Stef

[Pharo-project] FEATURE: User chooses preferred location for MC directory repositories

April 24, 2010

http://code.google.com/p/pharo/issues/detail?id=2329 Pharo image: Pharo 1.0 In Monticello Browser, when I click "+Repository" and select "directory," I'd love to be taken right to the directory where I keep my local repositories, instead of having to click to the same place over and over. I changed the following method: MCDirectoryRepository class>>morphicConfigure ^ (UIManager default chooseDirectoryFrom: (FileDirectory on: '/path/to/my/Repositories')) ifNotNil: [:directory | self new directory: directory] How should I store the default repository directory? Would anyone else find this helpful?

[Pharo-project] Change Window Size
by Lukas Renggli April 24, 2010

April 24, 2010

I am trying to change the window size in a headless build script on Linux, so that when I open the image on my Mac it appears bigger. DisplayScreen depth: DisplayScreen actualScreenDepth width: 1920 height: 1032 fullscreen: false There is no change though. Any other ideas on how to change the default VM window size?

[Pharo-project] [ANN] Metacello configuration of OSProcess
by Miguel Enrique CobÃ¡ Martinez April 24, 2010

April 24, 2010

Hi all, I have published the ConfigurationOfOSProcess in the MetacelloRepository of squeaksource. With this you can load OSProcess and its tests in PharoCore. Just evaluate in a workspace: Gofer it squeaksource: 'MetacelloRepository'; package: 'ConfigurationOfOSProcess'; load. Then evaluate ((Smalltalk at: #ConfigurationOfOSProcess) project version: '4.3.11') load. to load just the OSProcess, or: ((Smalltalk at: #ConfigurationOfOSProcess) project version: '4.3.11') load: 'Tests'. to load OSProcess and their tests. Tested in PharoCore 10506 Enjoy! -- Miguel CobÃ¡ http://miguel.leugim.com.mx
