Halo handle text missing?
by adrians-2 Nov. 21, 2012

Nov. 21, 2012

I'm using the latest 2.x one-click and I noticed that the halo text for the handles is missing. All I get is "unknown halo handle" for any handle I hover over. Is this a known issue with the latest updates? -Adrian -- View this message in context: http://forum.world.st/Halo-handle-text-missing-tp4655981.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

FileTree queries
by Chris Nov. 20, 2012

Nov. 20, 2012

Hi, I've just migrated to using FileTree with SVN and am wondering if it is possible to use it without the monticello.meta? You obviously get a lot of merge conflicts with these and the version file in particular, and I didn't really see much benefit when using SVN for commit comments and revision histories and so forth so have just been ignoring / deleting them. It seems to work ok for the most part and by loading packages with Gofer, but I feel like I'm fighting the system a bit and have not had much luck with Metacello in particular which I would like to get working again. Can anyone advise? Thanks Chris

fOSSa 2012
by Marcus Denker Nov. 19, 2012

Nov. 19, 2012

Pharo will participate to the fourth edition of the fOSSa Conference taking place from December 4 to 6, 2012 in Lille (France). The aim of the fOSSa (Free Open Source Academia Conference) is to reaffirm the underlying values of Open Source software: innovation & research in software development. While the first edition aimed at providing valuable information on the Open Source model at large, the second edition focused specific key-aspects of FOSS such as tech innovation,upcoming issues & challenges in the open development context and how open activities, collaboration and knowledge sharing is beneficial to academia, education & industry. The third edition look at the future of Open Source (Eco system, Trends, new territories, etc). The fourth edition will address in an open-minded style about: - Digital Geographic Strategies & the Native Generation, - FLOSS History with the movie: "Revolution OSâ followed by a debate, - Open Art, collaboration between art & science, - Licenses in the real life: no lawyers speeches, only facts & return experience, - Workshops to learn how to develop code for debian, gnome, apache, robotics ROS ... And, of course the usual fOSSa topics (Education & Community management). There will be a Pharo Workshop Dec 5th. "What marks the difference between fOSSa and other events is the air that you breath there. An event organized by passionate people, with passionate attendees as well â¦ and great speakers. Every year you can get some presentations of greater international events in advance (I remember the year of Arduino, to give you an example).â -- Gabriele Ruffatti -- SpagoWorld Blog 2012. fOSSa days are open to everyone and registration is free ! more information @ http://fossa.inria.fr -- Marcus Denker -- http://marcusdenker.de

Constrained Morph dragging
by Sebastian Nozzi Nov. 18, 2012

Nov. 18, 2012

Hello Morphic experts, I am learning / experimenting with Morphic and have the following question: "How do I constrain the movement of a dragged Morph?" As illustrated here: http://jqueryui.com/draggable/#constrain-movement (e.g. constrain within axis/container) So far the "hack" I came up with was to aggresively re-position the dragged Morph in its "drawOn:", if it is attached to a HandMorph: drawOn: aCanvas self owner isHandMorph "is there a better way to ask: am I being dragged?" ifTrue: [ self position: (self position x) @ 400 ]. super drawOn: aCanvas. I am sure this solution is pretty bad... I also get visual artifacts when I move the mouse up/down. Are there better ways/hooks for this? Generally: is there a method that is called on submorphs whenever the parent Morph was re-positioned/re-sized? Thanks in advance! Sebastian

CategorySaver
by Sebastian Nozzi Nov. 12, 2012

Nov. 12, 2012

Dear Pharo Community, I would like to share with you the work of my past weekend, and announce "CategorySaver". It is a simple utility to periodically save (file-out) a list of categories given (wildcards accepted). You can find it here: http://smalltalkhub.com/#!/~sebnozzi/CategorySaver And invoke it like this: CategorySaverPanel new openInWorld What motivated me to do this was loosing hours of work after image "hang-ups", without having saved before. In those cases I thought that it would be cool to have some kind of background process, that at least saved some recent version of the code I was working on. But only now I got myself to write it. Hopefully you are not like me, you know what you are doing, the VM never hangs on you, and don't need this utility ;-) For all others I hope you might find it helpful. Best regards, Sebastian P.S. I am kind of a Smalltlak newbie. So if you find things to improve in the code, I am glad about any tip / critique. P.S. 2 -- I was amazed at how easy it was to code the UI! UI programming in Squeak/Pharo was always an area where I thought must be incredible complicated, but thanks to UITheme's builder (Polymorph?) it's a breeze. Good work! P.S. 3 -- Did I have to manually add [ANN] to the subject? My apologies in this case. Also my apologies if this kind of mails correspond to only one of the lists.

I've moved the MongoTalk project to SmalltalkHub: http://www.smalltalkhub.com/#!/~francois/MongoTalk/ The original repo is still available but please use the new one. I don't know how to put a repo in global read/write on Smalltalkhub (is it possible?)

Global package cache
by Francois Stephany Nov. 11, 2012

Nov. 11, 2012

In an 1.4 summer image, executing: > MCCacheRepository default: (FileDirectory on: '/Users/fstephany/package-cache/'). in a workspace works fine. But: > StartupLoader default executeAtomicItems: { > StartupAction name: 'Global Monticello package-cache' code: [ > MCCacheRepository default: (FileDirectory on: '/Users/fstephany/package-cache/')]. > ... other StartupAction }. doesn't. The other StartupActions are executed fine (meaning that StartupLoader works). Is there something reseting the package-cache at startup?

Dear Pharoers Here is the result of the work we did around the consortium for Pharo for about 2 years. We took into account all your remarks over the years and we think that the result is good and corresponds to what the community can support. This consortium is important for Pharo's future and it will help us to deliver a system to help you making business. Our goal is to be able to collect fundings to pay at least one full time engineer. The idea is that all the consortium members will sign the same agreement. We will not handle modifications per partners. Now since we are starting the process if you spot some glitches on the form let us know. We can discuss and fully stabilize one version. We suggest to read the document. - If you agree to sign it and send it to us (in two copies if you do it by surface mail at INRIA - S. Ducasse - Pharo, 40, avenue Halley, Parc Scientifique de la Haute Borne, BÃ¢t.A, Park Plaza, Villeneuve d'Ascq, FR-59650, France.), so that we sign it too. - Don't forget to complete your legal mention on first page and your contact details on article 14 before signing. :) We will launch soon two web sites: - one for the Pharo user association and - one for the Pharo consortium. A side note: we will communicate about it later and separately but Inria decided to support the consortium by paying one extra year to Igor Stasenko. This is around 60 Keuros in addition to the year of Esteban Lorenzano and previous years of Igor. I really want to thank Inria for the constant support and the work of S. Karpf, P. Moreau and S. Perin.
