[Pharo-project] is pharo ready for production?
by Esteban Lorenzano Sept. 16, 2008

Sept. 16, 2008

Hi, I'm planning to start a new commercial, seaside based project in a few weeks, and I wish to start it in Pharo, but I'm afraid is not very stable yet... Can somebody tell me if is usable right now and if not, more or less when it will be? Thanks, Esteban

[Pharo-project] Throwing out the windowing support from core VM features
by Igor Stasenko Sept. 16, 2008

Sept. 16, 2008

Hello, i'd like to discuss with you this quite radical idea. I , in particular, not happy that windowing in squeak VM is mandatory. Sure, you can run VM with -headless (or whatever), but this actually not solving anything, since VM still in much of control, how to deal with squeak window and how to manage messages etc. What i would like to see, is to completely detach windowing functionality into a separate VM plugin, making sure that: a) VM can be built w/o this plugin b) a language side is in total control to decide whether create and use window & display or not. This would require to deprecate some of 'blue book' primitives, which coming as built-in VM features , such as: - displayBits & friends - fullDisplayUpdate - keyboard & mouse event handling The point is, that squeak grew out on many platforms and embedded devices. Some of them don't have a usual input devices, like keyboard & mouse, so it is completely pointless to require VM to support I/O with these devices as mandatory option. Same for display. I would be happy to have full control at language side whether i need display or not , instead of having it 'for free' from a start and then using workarounds to not show/use it using command line (while language side still thinks its present). -- Best regards, Igor Stasenko AKA sig.

[Pharo-project] Thinking about Pharo distribution
by Damien Cassou Sept. 16, 2008

Sept. 16, 2008

Hi, I've just started writing a wiki page which details the packages we plan to install in all Pharo distributions. In the Universe, the meta-package 'Pharo packages' permit easy installation of these packages. The wiki page is at: http://code.google.com/p/pharo/wiki/Packages. Please tell me what you think -- Damien Cassou Peter von der AhÃ©: Â«I'm beginning to see why Gilad wished us good luckÂ». (http://blogs.sun.com/ahe/entry/override_snafu)

[Pharo-project] Fonts
by Gary Chambers Sept. 15, 2008

Sept. 15, 2008

Specifically the "Alt-k" (opt for Mac users :-) ) keyboard option for ParagraphEditor... With FreeType and many fonts installed the menu is unmanageable (can't even get to the "more" option)... Perhaps it would be good to extend UIManager with an entry-point for choosing a font, passing off to the Polymorph font selector, in our case. Method in question: ParagraphEditor>>changeStyle. Regards, Gary.

[Pharo-project] Learning how to use Polymorph
by Hilaire Fernandes Sept. 15, 2008

Sept. 15, 2008

Gary, I am looking at Polymorph examples, to start learning it. >From your example, I see you have this ExampleBuilderMorph class Is it a class I can use to build my application interface, or do I need to subclass another MorphicModel (this last class is pretty large) ? I see you are using trait for this class also. Hilaire -- http://blog.ofset.org/hilaire

Building VM (Was: Re: [Pharo-project] Re: Hello everyone!)
by Igor Stasenko Sept. 15, 2008

Sept. 15, 2008

As always, things not working out of the box. - VM builds from unzipped VM sources OK - but for building with VMMaker generated sources, had to fix 'gnuify' file to make a clean build i dreaming to build vm straight from squeak, without horrid makefiles. I heard that Keith did a 'Bob' tool which can be used as a kind of make utility. But i think, to fully replace makefiles, it needs an OSProcessPlugin to be able to interact with OS/shell. 2008/9/12 Igor Stasenko <siguctua(a)gmail.com>: > 2008/9/12 Andrew Tween <amtween(a)hotmail.com>: >> Hi, >> "Igor Stasenko" <siguctua(a)gmail.com> wrote in message >> news:4a5f5f320809111213v2eec6200te2dcab47f03f6a58@mail.gmail.com... >>> >>> 2008/9/11 StÃ©phane Ducasse <stephane.ducasse(a)inria.fr>: >>>> >>>> I'm confused you do not use VMMaker for Hydra? >>>>> >>>>>> yes keep it there >>>>>> we have too much mailing-lists >>>>>> >>>>>> So can you do a unix/windows VM with the freeType pluging? >>>>>> >>>>> Sure i can, just give me details which/where i should take VMMaker & >>>>> platform sources & plugin. >>>> >>>> I thought that all this information was in the VM repository. >>>> >>> Can you point me to that VM repository? >>> >>> VMMaker are available on: >>> - squeakmap, >>> - http://www.squeaksource.com/VMMaker.html >>> - http://source.squeakfoundation.org (now is empty ,strange) >>> >>> The VM sources, are available on squeakvm.org SVN. >>> Is this places correct? >> >> For windows, you can use the source release from Squeak.org... >> http://www.squeakvm.org/win32/release/SqueakVM-Win32-3.10.7-src.zip >> >> Not sure about Linux. >> >>> >>> Also, where i can get freetype plugin and its platform sources? >> >> http://source.impara.de/freetype/Freetype-Plugin-JMM.53.mcz is the latest, >> but you might have to use an earlier version from the same repository - e.g. >> http://source.impara.de/freetype/Freetype-Plugin-tween.51.mcz >> >> For a long time, I have used the FT2Plugins that ship with Sophie. >> I think that we will need to get platform sources, makefiles etc. from the >> Sophie developers. >> >> The Windows ft2plugin.dll dynamically links to freetype6.dll . >> Once again we may need the Sophie developers help if we want to rebuild >> freetype6.dll (to move to a later version of Freetype, for example). >> >> You can find the freetype6.dll in >> http://dev.sophieproject.org/downloads/releases/Sophie1.0.3.zip , or >> alternatively in my plugins installer sar (zip) file >> http://map.squeak.org/accountbyid/46dcf6af-067d-43e3-9fc9-d7010e067153/file… >> >> The source for FreeType itself is on sourceforge - >> http://sourceforge.net/project/showfiles.php?group_id=3157&package_id=3121 >> The freetype6.dll was built from version 2.2.1 of FreeType. >> >> The Linux FT2Plugin dynamically links to the libfreetype.so.6 library that >> ships with most (all?) linux distributions. >> >> The bitblt modifications are currently in a changeset that should be >> installed after installing vmmaker - you can get it here... >> http://www.zen61439.zen.co.uk/bak/bitBlt_plugin_enhancements/FreeTypeBitBlt… >> (In a few days time this url will no longer work as I am changing ISP - so I >> have also attached it to this post) >> >> I know that this is all quite complicated and confusing, and it may take >> some time to get all the pieces of the puzzle in place. >> Thank you for your interest and help. >> > > No, it is not complicated.

Hi is there a way that I can trigger the recompilation of a class when its superclass changes? I tried ComponentLikeModel suclasses do: [:each | each superclass: ComponentLikeModel superclass] but I did not get the recompilation. Stef
