Re: [Pharo-users] FileTree queries

Thanks Dale, I'll give the Baseline stuff a go. I've only been trying to use my old Configuration for it's dependency information and purely in a loadBleedingEdge capacity, as it's version capabilities are obviously redundant in this context. I'll try it with the meta back in there, but was having some issues with the version file and conflicts on each commit. Oh and just as an aside, it's worth pointing out that FileTree is only compatible with SVN 1.7 (all the meta contained at the top level) as I found when I tried it on a system with 1.6 installed :-) > Chris, > > You have to have the meta data for things to work ... > > Speaking of Metacello... since you are using SVN for managing our package source, it isn't really necessary to manage the classical ConfigurationOf (saving the mcz file versions for each commit to your SVN repo is redundant), so in the Metacello Preview I have introduced the notion of a BaselineOf where you only need to maintain the baseline information (no versions).

Chris, You have to have the meta data for things to work ... Speaking of Metacello... since you are using SVN for managing our package source, it isn't really necessary to manage the classical ConfigurationOf (saving the mcz file versions for each commit to your SVN repo is redundant), so in the Metacello Preview I have introduced the notion of a BaselineOf where you only need to maintain the baseline information (no versions). The BaselineOf can be used interchangeably with the ConfigurationOf and is much less overhead to maintain ... The Preview[1] is not in general release, but I use it on a daily basis for my work (I store my code on github) and would welcome feedback on your experience using the Preview ...

Re: [Pharo-users] FileTree queries

by Dale Henrichs

Chris, "is possible?" yes ... I've gone through several different versions of FileTree where I've played different games with the meta data ... in the end I figured that to make it simple for folks to move back and forth that the meta data was best left intact ... With that said, I have several projects that are 100% stored in git and I am mightily annoyed by the extra meta data showing up as changes so I am getting close to nuking the meta data ... as an option .... but I have been busy working on "real projects" instead of spending almost this entire year working on infrastructure so I probably won't be making the changes real soon:) Dale ----- Original Message ----- | From: "Chris" <cpmbailey(a)btinternet.com> | To: "A friendly place where any question about pharo is welcome" <pharo-users(a)lists.gforge.inria.fr> | Sent: Tuesday, November 13, 2012 11:18:00 AM | Subject: [Pharo-users] FileTree queries | | Hi, | | I've just migrated to using FileTree with SVN and am wondering if it | is | possible to use it without the monticello.meta?

Halo handle text missing?

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.

fOSSa 2012

by Marcus Denker

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

Re: [Pharo-users] Constrained Morph dragging

by Sebastian Nozzi

I came up with this... does what I need and I have no visual artifacts anymore. Still, I'm not happy for having to override a private method in order for this to work... :-/ Overridden existing method in my Morph subclass: privateFullMoveBy: delta super privateFullMoveBy: delta. (self wantsToConstrainDragging & self isBeingDragged) ifTrue: [ self adjustPositionWhileDragging ] New methods in my Morph subclass: isBeingDragged ^ self owner isHandMorph wantsToConstrainDragging ^ true adjustPositionWhileDragging self position: (self constrainedDragPositionFrom: (self topLeft)) constrainedDragPositionFrom: aNonConstrainedPosition "Adjust the position to be constrained however you want. In this case horizontally at y=450" ^ (aNonConstrainedPosition x) @ 450. You would need to override only "wantsToConstrainDragging" and "constrainedDragPositionFor:". Any critique to the code and/or naming welcome! :-) Cheers, Sebastian

Constrained Morph dragging

by Sebastian Nozzi

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
