> Mark your calendars: on Thursday March 31 & Friday April 1 we are organising the Pharo Days 2016. This year we moved the location to Namur, Belgium, just a bit south of Brussels, at the very beautiful location of the ‘Cercle de Wallonie’ overlooking the river Meuse.

Is there a way to set a default selection to a list presentation? so that
when I open the browser, the morphic list has already a value selected.
I tried that:
tmpBrowser := GLMTabulator new.
tmpBrowser row: #list.
tmpBrowser transmit to: #list; andShow: [:a |
display: [:input | input];
tmpBrowser openOn: #( b c d v a d f r).
but the list still open with nothing selected
Alex Syrel, Andrei Chis and I are happy to announce a new addition to the
GTSpotter, a novel interface for spotting objects.
GTSpotter has two goals:
- Provide a uniform yet moldable interface that can work on any object, and
- Handle searching through arbitrary levels of object nesting.
We think this will have a significant impact on the development workflow in
Here is a couple of screenshots:

A detailed description is available here:
It works already in Pharo 3.0 and can be played with by following the

since I wanted to use DarkTheme I played around with TRMorph (since seeing
giant white rectangle in dark theme is not very nice).
What I have done is moved the background color setting to `surface clear:`
(instead of the original aCanvas fillRectangle).
And then if theme background luminance is dark (>0.5), I invert all the
colors in the visualization.
For dark theme the background is black, and not the theme background - at
least to me it seems that black is much clearer.
Is this something that could be incorporated?
And the modified code:
"aCanvas is a FormCanvas"
"aCanvas fillRectangle: bounds color: trachelCanvas color."
"The drawing has to be done when a change in the shapes occured or when
there is an animation."
surface drawDuring: [:cs |
surface clear: trachelCanvas color.
"We display the elements that are subject to the camera"
translateBy: (self extent / 2) asFloatPoint;
scaleBy: trachelCanvas camera scale asFloat;
translateBy: trachelCanvas camera position negated asFloatPoint.
trachelCanvas shapes do: [ :trachelShape |
trachelShape drawOn: cs.
"We display the elements that are _NOT_ subject to the camera"

I am wondering why there are ~1000 tests less on Moose6.0 image between 7 oct and today.
It seems that XML tests are not run anymore. Is it wanted ?

I'm trying to understand the code behind the figure here to rotate labels:
So, I made a minimal example to start with, here (code is at
Now I would like to rotate the text to made it look like the first
image. I presume that the code that made this possible for the first
case is this one:
RTBundleBuilder>>createLabelFor: e view: aView
| lbl |
lbl := label elementOn: e model.
self interaction setUpElement: lbl.
aView add: lbl.
e addCallback: (TRTranslationCallback new block: [
| angle |
angle := (e position - center ) theta.
lbl translateTo: e position+((lbl trachelShape
notRotatedWidth/2) * (angle cos @ angle sin)).
angle := angle radiansToDegrees.
angle := angle + ((angle between: 90 and: 270) ifTrue: [ 180 ]
ifFalse: [ 0 ]).
lbl trachelShape angleInDegree: angle ] ).
e translateTo: e position.
but I can not quite understand the lines
lbl translateTo: e position+((lbl trachelShape notRotatedWidth/2) *
(angle cos @ angle sin)).
angle := angle + ((angle between: 90 and: 270) ifTrue: [ 180 ] ifFalse:
[ 0 ]).
Could some body explain me how to incorporate rotation to the first
basic example at http://ws.stfx.eu/N6ZG4BAIBO00 (second image of this mail).
just in case this is not a known bug: Intensive use of Roassal2 in Pharo 5 causes a segfault of the mac vm. A crash.dump is attached. It’s the vm I got just now ( wget --quiet -O - get.pharo.org/50+vm | bash ) and Pharo5 with Alexes’ 17280 slice to make Roassal visualize shapes correctly.
To reproduce, all I need to do is have a visualization open with a layout animation and after some time it will crash. I use this in LRP and I can give easy steps to reproduce if needed.
