[Pharo-project] christmas coding parties?
by StÃ©phane Ducasse Dec. 5, 2009

Dec. 5, 2009

Hi all I would like to organize a couple of coding parties around christmas. The 18 of december? is one possibility (even if I can only start at 11h). So if some of you are close to lille during holidays we could have fun coding together. I would like to organize a moose day too. I want to code what I have in mind with CAnalyzer and mondrian. Stef

[Pharo-project] file encodings
by Tudor Girba Dec. 5, 2009

Dec. 5, 2009

Hi, I know that there was a long discussion regarding opening of files, but I did not see a resolution. I would like to be able to read files regardless of the encoding. I am using this code: (CrLfFileStream readOnlyFileNamed: fullPath) contentsOfEntireFile" but I get an error when I reach a file in Latin 1 (ISO-8859-1). How can I safely deal with this issue without getting hurt? Cheers, Doru -- www.tudorgirba.com "When people care, great things can happen."

[Pharo-project] about keys returning a set

Dec. 5, 2009

Nicolas I was discussing with lukas and we would be interested to get your changes to dictionary keys (Ihope that this icorrect since I'm dead) We would like to integrate your changes. Do you have a basis that we could work? Else we can just try in the image directly. Stef

[Pharo-project] macintosh cocoa 32/64bit & 64/64bit VM goes BETA
by John M McIntosh Dec. 4, 2009

Dec. 4, 2009

Ok, it's time for the community to do some testing. ESUG provided me with some funding to take the existing iPhone VM source and extend that to build a new hosting platform using Cocoa on the macintosh and to enable the VM to run in 32 or 64 bit mode and work with a 32 or 64bit image. I have placed two Alpha test VM s in the experimental folder sub-folder COCOA found in the usual places via http://smalltalkconsulting.com/squeak.html There are two VM's (a) a 32/64 bit VM that runs 32bit squeak images in 32bit (powerpc, intel) or 64bit (intel) mode. (b) a 64/64 bit VM that runs 64bit squeak images in 64bit (intel). The VM currently runs on 10.5.x and 10.6.x Support for 10.4.x might happen, we will see. Until I sort out the re-integration of the source code into the squeakvm.org SVN tree you will find the source at isqueak.org Issues, Oh lots. It's a fairly high mountain of material that needs to be tested. Things that should work. (a) access to files and directories UTF8 support only. (b) Full screen support (c) Sockets (d) Basic Sound (better than in the 3.x/4.x VMs) (e) jpegplugin2 (f) cut/copy/paste of text data (from/to) squeak and respect UTF8 chars (g) drag and drop of files into squeak Right now it does not: (a) Support a internet browser as a browser plugin. (b) The 64bit VM has no plugins at the moment. (b2) I've not included any plugins with the 32/64bit VM. Existing plugins might work if the VM is running as "Open in 32bit mode" someone can confirm that. (c) No macintosh host menus, or serial port support (d) No Areithfa Ffenestri multiple-window support (e) No 1, 2, 4, 8, 16 bit appearance support. Things I know about. (a) double clicking *.images when the 5.x VM is running sometimes does not open a new VM. (b) tossing a 32 image at the 64/64 bit VM or a 64 image at the 32/64 VM doesn't give visual feedback that it won't open the image. (c) Full screen grabs all the screens, yes that will change Thoughts on internal plugins. Hint we should have TEST cases so we can confirm if all this stuff works. It would be extremely helpful if someone wanted to work on that. No doubt someone *could* run all the current tests for a 32bit image and see what breaks. However you'll need to explain where and what, versus Oh it just crashed... ADPCMCodecPlugin, untested. Squeak3D, Likely busted due to use of (int) data types in 64bit mode. B2DPlugin, untested. BitBltPlugin, untested. BMPReadWriterPlugin, untested. ZipPlugin, untested. DSAPrims, untested. SqueakFFIPrims, untested. FFTPlugin, untested. FloatArrayPlugin, untested. GeniePlugin, untested. HostWindowPlugin, No support yet JPEGReaderPlugin, untested. Klatt, untested. LargeIntegers, untested. Matrix2x3Plugin, untested. MiscPrimitivePlugin, untested. ObjectiveCPlugin, untested. RePlugin, Likely busted due to use of (int) data types in 64bit mode. SecurityPlugin, untested. SoundCodecPrims, Likely busted due to use of (int) data types in 64bit mode. SoundGenerationPlugin, Likely busted due to use of (int) data types in 64bit mode. StarSqueakPlugin, untested. SurfacePlugin, untested. UUIDPlugin untested. Possibly Large Integers may have a problem in 64bit image mode, but we have to have some discussion if the (unsigned int *) used by one routine is on purpose or an oversight. 64 bit images. We need to built a 64bit Closure image. **** I've no time to do that. *** David T Lewis provided a somewhat current Squeak.image which you'll find on the ftp site. If you build a 64bit image you need to do that on a PowerPC, or make a copy of your VM on macIntel and flip the "Open in 32-bit mode" and the "Open in Rosetta" to on. You will only see the "Open in 32bit mode" if it's a 64bit VM, and the "Open in Rosetta on os-x for 10.5 or 10.6 (if you installed it) Follow the obvious instructions. No doubt some is required to take the code and build a MC change set for Pharo or Squeak Thrunk use so that anyone can convert an existing image. Also see http://bugs.squeak.org/view.php?id=5239 http://bugs.squeak.org/view.php?id=5240 Building your own VM? Hopefully someone will attempt this so I can see if I checked in all the changes. 32bit image VM pick SqueakPureObjc and set #define SQ_VI_BYTES_PER_WORD 4 for a 64bit image reading VM pick SqueakPureObjc64*64 and set #define SQ_VI_BYTES_PER_WORD 8 in the required places. PS You'll find that building a 32/64 VM using GNU's tool chain will give you lousy performance when running as a 64bit VM, more on this later. ---------------------------------------------- Oh and lastly I'm looking for some paid work (smalltalk or objective-c (mac/iPhone) If anyone requires a Smalltalk consultant, or an iPhone app built, please email me. -- =========================================================================== John M.

Re: [Pharo-project] A centralized repository (Going a step forward Gofer and Metacello)
by Dale Henrichs Dec. 4, 2009

Dec. 4, 2009

Esteban, I think that what you are proposing makes a lot of sense, although I am a bit biased ... a central repository would definitely make it very simple to find projects that are managed... It seems that in addition to to the Monticello repository of configurations, a catalog website that provided a searchable index on the projects and the project meta data (project description ... release status ... project dependencies ...). Having a central repository is a good first step... I have a cross-platform bias. Many of the Pharo projects can be ported to GemStone (and Squeak) using a common Metacello configuration, so I think the central repository would end up serving cross-platform users. FYI, yesterday I created a google group for Metacello discussions (http://groups.google.com/group/metacello/members) As a Metacello user, you will want to join.

by Alain Plantec Dec. 4, 2009

-------------------------- whatever value is set to allowUnderscoreAssignment preference, underscore is always allowed. the fix seems simple. it consists in changing the Scanner typeTable initialization. by replacing the line newTable at: $_ asciiValue put: #leftArrow. by newTable at: $_ asciiValue put: #xUnderscore. in Scanner class>>initialize -> SLICE-allowUnderscoreAssignmentFix-AlainPlantec.1 in inbox --------------------------- Alain
