[Pharo-project] Pressed Morph feedback on PharoTheme
by Goubier Thierry May 29, 2012

May 29, 2012

I tried to add some feedback when manipulating scrollbars and buttons in the default Pharo Theme. Adding the following four methods to PharoTheme gives a reversed look when clicking on a scrollbar or a button : PharoTheme>>buttonPressedFillStyleFor: aButton "Return the pressed button fillStyle for the given button." (aButton valueOfProperty: #noFill ifAbsent: [false]) ifTrue: [^ SolidFillStyle color: Color transparent ]. ^ self glamorousReverseFillStyleFor: aButton height: aButton height PharoTheme>>glamorousReverseFillStyleFor: aMorph height: anInteger "Return the reversed button fillStyle for the given button." | baseColor | baseColor := self glamorousBaseColorFor: aMorph. ^ self glamorousReverseFillStyleWithBaseColor: baseColor for: aMorph height: anInteger PharoTheme>>glamorousReverseFillStyleWithBaseColor: aColor for: aMorph height: anInteger | top bottom | top := aColor twiceLighter. bottom := aColor. ^(GradientFillStyle ramp: { 0.0->bottom. 0.7->top.}) origin: aMorph bounds origin; direction: 0 @ anInteger; radial: false PharoTheme>>scrollbarPressedThumbFillStyleFor: aScrollbar "Return the pressed scrollbar fillStyle for the given scrollbar." ^ (self glamorousReverseFillStyleWithBaseColor: aScrollbar paneColor for: aScrollbar height: aScrollbar height) direction: (aScrollbar bounds isWide ifTrue: [0 @ aScrollbar height] ifFalse: [aScrollbar width @ 0]) It makes the default interaction a lot more reactive (i.e. you notice on screen when you are pressing on a button). Side note about UI changes in Nautilus: will there be any changes about the Groups/Hierarchy/Class/Comments buttons ? I have a hard time getting used to them (lack of selection/state clues, unusual behavior for buttons).

[Pharo-project] Headless Pharo on Mac OS X?
by Mark Smith May 29, 2012

May 29, 2012

Hi All, I find that I need headless mode to work on OS X... could anyone suggest where I should start? I'm guessing this will be somewhere in the VM? FYI: headless mostly works in Elliot's latest CogVM, the only problem is that the icon still shows up, but I think this can be fixed with a little work. All the best, Mark

[Pharo-project] [update 2.0] retracted update: 2.0 100
by Marcus Denker May 29, 2012

May 29, 2012

Hello, #100 is faulty. Please do not use it. #99 is the good one. Now in parallel, the build server is broken. So the latest update there is *wrong*. this is is good: https://ci.lille.inria.fr/pharo/view/Pharo%202.0/job/Pharo-2.0/106/ Sorry for the confusion, I thought that I fixed it on Saturday already, but I forgot to remove the #100 update...

[Pharo-project] [ANN] Fuel Release Version 1.8
by Martin Dias May 29, 2012

May 29, 2012

Hi all, We are proud to announce Fuel 1.8 with a lot of new features and documentation. Of course, we don't stop working but it was time to freeze a stable version. Fuel is an open-source general-purpose object serialization framework developed in Pharo Smalltalk environment. More information on our website [1]. Fuel works out of the box in Pharo from 1.1 up to 2.0 (checked at #20094). Please check our documentation [2] for complete installation and use guides. Below, there are some remarkable changes. - Much more complete user guides. - Improved API for customizing how graph is traced. - FuelMetalevel: serialization of stuff like classes and compiled methods moved to an optional package. - Customize objects to be treated as globals. - Migrations: declare at materialization time class and variables renames. - Weak references properly managed. Thanks to Juan Vuletich and Levente. - Thanks Pavel for helping us improving FuelPackageLoader with wonderful ideas and bug reports. - Serialization speed up on large graphs by using specialized collections. Thanks Levente. - Encoder and Decoder: new reifications that clarify the design. Thanks Colin Putney. - Optimized serialization of "clean" BlockClosures, which don't need the whole stack of contexts. Thanks Juan Vuletich and Eliot Miranda. - Added a clear error hierarchy. - Debug facilities, including graph visualization using Roassal. Thanks Alexandre and Doru. - Many more new tests. Including those from extension packages, we have almost 600 tests. - Repository moved from 'http://www.squeaksource.com/Fuel' to 'http://ss3.gemstone.com/ss/Fuel'. If you are a Fuel user we are not aware of, please let us know! Best regards, Martin and Mariano [1]: http://rmod.lille.inria.fr/web/pier/software/Fuel [2]: http://rmod.lille.inria.fr/web/pier/software/Fuel/Version1.8/Documentation

[Pharo-project] Refactoring Questions
by Camillo Bruni May 28, 2012

May 28, 2012

after having a look with ben at the current refactoring implementation in Nautilus we found that the "Extract into temporary" refactoring is most of the time not that useful. I wonder wether it would make sense to loosen the requirements on conserving behavior... consider the following example where we extract "self foo" into the temporary "tmp": =========================================== foo ^ self foo even ifTrue: [ self foo * 2 ] ifFalse: [ self foo / 2 ] actual result ============================= foo | tmp | tmp := self foo. ^ tmp even ifTrue: [ self foo * 2 ] ifFalse: [ self foo / 2 ] proposed result =========================== foo | tmp | tmp := self foo. ^ tmp even ifTrue: [ tmp * 2 ] ifFalse: [ tmp / 2 ] =========================================== note that the proposed solution is not side-effect free. However the given refactoring hardly makes ever sense, since this action can be easily done manually in less time. given that you first have to find the proper menu-item. best cami
