[Pharo-project] HostWindows rewrite
by Igor Stasenko Nov. 9, 2008

Nov. 9, 2008

Hello list, i started design of new plugin, which is conceptually based on HostWindows, but will be more integral & flexible. The plan is to move windowing & events handling into new plugin and at same time, completely remove cruft from basic VM functionality. - you are in total control when to create a window - multiple windows support (will require refactoring in Morphic code) - control the window style/appearance, including: title, titlebar presence, window icon, size & position, pixel format, transparency (aka layered window), border style (resizeable or not, or completely w/o border ) - control video modes (if its provided by platform) and fullscreen window mode - events are now bound to particular window - different notification events like changing window position / activating or deactivating Plugin is publishing a list of available window attributes. Different platforms, depends on implementation, may or may not support different window attributes. Instead of spawing dozens of primitives , like setWidth/setHeight/setTitle/getTitle etc etc, plugin will have only two primitives - get/setWindowAttribute. So, to set an X position of window, a code will look like: window primAttributeAt: #x put: 10. or to hide window: window primAttributeAt: #visible put: false. or to set multiple attributes in batch manner: window primSetAttributes: { #x -> 10. #y->20. #visible->false. }. I'll try to cover a most basic attributes, available on major platforms for the initial implementation. What you'll never see in new plugin: - native widgets support or any kind of dealing with native widgets/controls. Awaiting for your comments or suggestions. -- Best regards, Igor Stasenko AKA sig.

[Pharo-project] A really important point
by StÃ©phane Ducasse Nov. 9, 2008

Nov. 9, 2008

Hi all I just want to share a part of my vision for pharo with you. This email is raised by the discussion around SunitExtensions. Of course we should look at what the other people are doing. Now I think that this is really important that we incrementally adopt and have the courage to experiment little features at a time. For example lukas and alex enhanced the MC browser and they would have never done it as a specific task. We are all busy and improvements will go that way step by step with sometimes large chunk like MC2 or other but the main drive will be incremental. and we should let incremental change a chance else we will not make progress. Now of course I would love to be able to hire an engineer working full time on pharo. but right now we cannot. Stef

[Pharo-project] [ANN] Sourcetalk
by Lukas Renggli Nov. 9, 2008

Nov. 9, 2008

Hello everyone We am happy to announce the first release of my bachelor project which is called Sourcetalk. Most of you know already Squeaksource (www.squeaksource.com) which works with Monticello. Meanwhile Colin Putney released first versions of Monticello 2, which aims to not only support Squeak/Pharo but all Smalltalk dialects. My bachelor work contains the making of a web application, with Smalltalk, Seaside, Magritte and Pier, as an interface to a Monticello 2 repository, similar to Squeaksource. Feel free to give it a look and to try it out at <http://scg.unibe.ch/sourcetalk>. Should you encounter bugs, please report them to me (andreaquadri(a)students.unibe.ch) Keep in mind that this is an early version and only ment for experimentation. Do not store your important projects on the server (yet). We'll setup a real server that is properly persistent and backed up at its own domain at a later point this year. To give it a try from your image you need to load Monticello 2 into a recent Pharo/Squeak image: http://www.wiresong.ca/static/releases/Monticello-2.0.29.zip Then load in the attached file-out. It contains a new repository type and some patches to Monticello 2 to make it work with Sourcetalk. Greetings Andrea Quadri Lukas Renggli -- Lukas Renggli http://www.lukas-renggli.ch

[Pharo-project] About etoy cleaning
by StÃ©phane Ducasse Nov. 9, 2008

Nov. 9, 2008

Hi guys I just wanted to let you know that I'm working on etoy cleaning from Object, Morph and friends. And I will probably do some mistakes (because this is complex). I'm trying to do that concentrated but still this is serious beast. Now I'm keeping a list of my progress at this page http://code.google.com/p/pharo/w/edit/CurrentlyWorkingOn so that you can follow my progression and that I'm not lost either. I'm using gary etoy removal and going over his list and checking senders of senders .... and verifying when I have doubts. and I'm finding missed points from time to time and this is normal when we see the complexity of etoy and morphic together. So gary may be at the end I would appreciate that you have a look at the stuff I'm removing. May be by doing a "changes" comparison. Right now I'm cleaning object and I will keep a list of the difficult methods I did not fixed yet. May be these ones will be easier to treat when etoy will be removed. Stef

[Pharo-project] Squeak Carbon OS-X VM 3.8.19beta1U ships
by John M McIntosh Nov. 9, 2008

Nov. 9, 2008

This VM has a number of fundamental changes and can be found via ftp or my idisk at http://www.smalltalkconsulting.com/squeak.html (a) I have changed how image files are read. Users should verify the VM still will load and work with their current images on their current systems. I have tested with macintel on 10.5.x and powerpc on 10.4.x but have NOT tested on a 10.3.x powerpc system, if some 10.3.x user could do that it would be appreciated. (b) I no longer cwd (change working directory) at startup time to the VM directory, and I added a change so if the image name is for example Squeak.image we attempt to find that in the VM directory. This change *should* enable the ablility to launch a VM and image and startup file from a command line using relative file paths, versus having to give absolute paths. Users are welcome to test and confirm this feature works as expected with relative and absolute paths for the image and startup file. Memory allocation background: In the past we have read the image file into a pre-allocated chunk of memory allocated via mmap, now I have changed to a more complicated but faster method of reading which then allows us to someday depending on your VM to avoid re-swizzling pointers for an image that is launched on a unix, windows, or iPhone since all oops should start on the 500MB boundary. What happens is we mmap the image file with copy on write mmap into a segment of memory starting at a real address of 500MB (500*1024*1024), the next virtual memory page follow the size of the file then is anonymously mmap upto the maximum memory size choosen for the implmentation. In this case we allocate 512MB of memory which is a settable option in the info.plist. Because of mmap differences between operating systems, and versions of operating systems I cannot say if this will work on your favourite device, but it does seem to work on os-x 10.4 & 10.5 for powerpc and macintel, plus on iPhone 2.x. Post loading we check to see if the memory start location is the same as the memory start location when the image was saved. If not then we adjust all oops pointers by the difference in addresses. If the saved image was at the 500MB boundary then we do not need to walk all the oops to swizzle pointers, this saves some CPU cycle and becomes important on slow devices like the iPhone, or when we want to use Squeak as a scripting engine and expect really fast startup. -- = = = ======================================================================== John M.

[Pharo-project] Repaint does not work
by StÃ©phane Ducasse Nov. 9, 2008

Nov. 9, 2008

Hi adrian do you remember if you did something with the SketchEditorMorph when you optimise memory, because now I cannot repaint a form, I get a plainCursor error since the palette is nil. To reproduce bring halos on the pharo logo click on repaint you get one DNU because Prototype classVariable is nil and not a PaintBoxMorph then if you bring again the halos and move the mouse over the area we get a plainCursor DNU. I was not working on this area so I imagine that it may be your cleans. was working 10107 but not in 10133 Sytef

[Pharo-project] Fwd: FOSDEM 2009, call for participation
by Damien Pollet Nov. 9, 2008

Nov. 9, 2008

---------- Forwarded message ---------- From: Mattias 'Tias' Guns <mguns(a)fosdem.org> Date: Sun, Nov 9, 2008 at 1:52 PM Subject: FOSDEM 2009, call for participation To: Fosdem Lightning Talks <lightningtalks(a)fosdem.org> Hello Lightningtalk speakers of last year, I hope you enjoyed participating in FOSDEM 2008 (if not, let me know). We are currently preparing for FOSDEM 2009, and we have sent out a joint call for participation, including devrooms, stands and lightningtalks, see http://fosdem.org/2009/ To maximize project's chances, we do not allow projects that participated in fosdem last year to do a lightningtalk this year. However if you liked participating, may I ask you to help spread the word, and inform other projects and developers about the opportunities at FOSDEM. Below is our call for participation. Thank you for sending it around, Tias FOSDEM Lightning Talks FOSDEM is probably the most developer-oriented Free and Opensource conference, taking place in Brussels, Belgium on Saturday 7 and Sunday 8 February 2009. Apart from having many invited speakers, the conference offers developer rooms, stands and lightning talks to projects from the Free and Opensource community. We hereby welcome proposals from projects to participate in organizing a devroom, manning a stand or holding a lightning talk. As every year, we have only a limited number of rooms, space for stands and lightning talk slots. Since we always receive more requests than we can host, a committee within the FOSDEM organizing team will review all proposals. Selection will be based on possible impact, our experience of previous editions and diversity in the offerings. *** Devrooms We offer large projects a devroom during the conference. A devroom is a room in which projects can organize their own schedule made of presentations, brainstorming and hacking sessions. Our goal is to stimulate developer collaboration and cross-pollination between projects, and as such we strongly favor projects with similar goals and domains to host a devroom together. See http://fosdem.org/2009/call_for_devrooms_and_stands *** Stands We offer stands to projects that want to present themselves to the visitors in a more personal fashion. Stands can be used to share information, demo software, sell merchandizing or give away goodies. See http://fosdem.org/2009/call_for_devrooms_and_stands *** Lightning talks We offer lightning talks to all other projects that want to present themselves. A lightning talk is a short talk in which a project can introduce itself, talk about recent developments, or share exciting new directions. See http://fosdem.org/2009/call_for_lightningtalks FOSDEM 2009 will be the 9th edition of the event, which has been steadily growing every year in importance and in the number of visitors. Our goal is to provide a platform to Free and Opensource projects to meet, discuss, present their current and future developments, both to their own developer and user community as to other projects that are present. Given the large amount of active contributors from many different projects present during the conference, it is an exceptionally well suited occasion to share goals and ideas with people from other communities, which is something we strongly encourage and do our best to support. Of course, the event only lives through the projects that take part in it, and through the many FOSS contributors who attend. We merely do our best to provide the best possible service to the FOSS community at large. *** Key dates: * 2008-11-22: Deadline for devroom & stand requests * 2008-11-30: Devroom & stand acceptance notification * 2008-12-26: Deadline for lightning talk requests * 2008-12-29: Lightning talk acceptance notification * 2009-01-09: Deadline for final devroom & lightning talk schedules * 2009-02-07 to 2009-02-08: FOSDEM 2009 For more information, visit http://fosdem.org/ -- Damien Pollet type less, do more [ | ] http://people.untyped.org/damien.pollet
