how to increase memory for the jvm through jniport?
by Tudor Girba
Hi,
When using JNIPort I am getting a "java.lang.OutOfMemory: Java heap space".
To go around this, I would need to provide more memory to the JVM.
Essentially, I would like to provide the correspondent of a command line
like:
java -Xmx4000m
How should I do this?
Cheers,
Doru

Important problem due to syntax highlighting
by Alexandre Bergel
Hi!
Here is a serious bug: Type (in a playground or code browser) the following: #(‘hello’)
I get a violent #isNumberLiteralToken DNU on RBErrorToken
Also, consider the following:
The closing ) has the same color than the symbol. Which is not correct. It should have the same color than the opening (
Apparently these error do not occur in Pharo 5

Text rotation in Roassal
by Alexandre Bergel
Hi!
I am experiencing a weird behavior when rotating text: an extra space seems to have been inserted. For example the screenshot shows ‘J anu ary’.
Anyone has seen this before? Any idea how to fix it?
Cheers,
Alexandre

Roassal TRConstraint deprecation
by Peter Uhnák
Hi Alex,
you've marked TRConstraint as obsolete, however not all behavior has been
yet implemented in new RTConstraint.
Namely methods from "public - resizing", "public - camera", and "public -
aligning".
Secondly I am not sure about the name of RTConstraint class>>child:parent:
(Tudor also didn't like the name when he saw it. :))
I don't think the naming fits well into Roassal... maybe RTConstraint
class>>on:backElement: ?
Thanks,
Peter

RTEdgeBuilder very strange behavior
by Peter Uhnák
Hi Alex,
I've encountered a very strange behavior and I cannot tell what is going on.
This is old RTEdge build*
~~~~~~~~~~~~~~~~~~~~~
| v es |
v := RTView new.
es := RTBox elementsOn: (1 to: 10).
v addAll: es.
es @ RTDraggable.
RTEdge buildEdgesFromObjects: (1 to: 10) from: #yourself toAll: [:value |
(Array with: value -1 with: value + 1 with: value + 2) ] inView: v.
RTForceBasedLayout on: es.
v addAnimation: (RTSpringLayoutStepping new view: v).
v @ RTDraggableView.
^ v
~~~~~~~~~~~~~~~~~~~~~~~~
the layouting is almost instant,
however if I use RTEdgeBuilder suddenly it is very slow
~~~~~~~~~~~~~~~~~~~~~~~~
| v es |
v := RTView new.
es := RTBox elementsOn: (1 to: 10).
v addAll: es.
es @ RTDraggable.
RTEdgeBuilder new
view: v;
elements: es;
connectToAll: [:value | (Array with: value -1 with: value + 1 with: value
+ 2) ].
RTForceBasedLayout on: es.
v addAnimation: (RTSpringLayoutStepping new view: v).
v @ RTDraggableView.
^ v
~~~~~~~~~~~~~~~~~~~~~~~~~~
the view still has the same number of elements and edges and the output
looks identical, but with EdgeBuilder is it very slow.
Profiler is showing me that with EdgeBuilder it spends a lot of time in
attach points and with moving edges, which is strange.
In either case it has no right to be so slow with 10 elements and 26
edges...
Can you reproduce this behavior?
Thanks,
Peter

Glamour Magritte Example Broken
by Gareth Cox
Hi all
I've just tried to use GLMAnnouncingCollection and found something odd.
When you use it and its passed into a block (such as TableColumn
computation:) it passes in the whole collection, not each item.
Change the collection to OrderedCollection and it works as expected
(except you lose the behaviour of GLMAnnouncingCollection).
So, to find out how this is used I go to the examples provided,
specifically "Magritte presentation".
This has the following comment:
"self new magritte openOn: GLMMagrittePersonExample sampleData"
"GLMMagrittePersonExample sampleReset"
"note, sampleData is aGLMAnnouncingCollection"
This does not work as expected (or indeed how it used to).
I've looked at this before and done work with Magritte using this
example with Diego Lont and Stephan Eggermont.
Its definitely become broken since the last time I looked at it.
Can we confirm?
Thanks

Re: [Pharo-dev] GanttChartMorph openOn: aCollectionOfActivities ?
by Alexandre Bergel
Hi Hannes!
Here is a first shoot paired-programmed with Juraj using Roassal:
-=-=-=-=-=-=-=-=-=-=-=-=
b := RTTimeLine new.
b addEntry: (RTTimeLineEntry new identifier: #WP1; start: 0; end: 5).
b addEntry: (RTTimeLineEntry new identifier: #WP2; start: 5; end: 8).
b addEntry: (RTTimeLineEntry new identifier: #WP3; start: 7; end: 10).
b axisX numberOfLabels: 5.
b
-=-=-=-=-=-=-=-=-=-=-=-=
Here some slightly more elaborated example:
-=-=-=-=-=-=-=-=-=-=-=-=
“One color per entry"
| b d |
b := RTTimeLine new.
b addEntry: (RTTimeLineEntry new identifier: #c1; start: 0; end: 5).
b addEntry: (RTTimeLineEntry new identifier: #c1; start: 6; end: 8).
b addEntry: (RTTimeLineEntry new identifier: #c2; start: 0; end: 5).
b addEntry: (RTTimeLineEntry new identifier: #c2; start: 8; end: 10).
b addEntry: (RTTimeLineEntry new identifier: #c3; start: 0; end: 10).
b addEntry: (RTTimeLineEntry new identifier: #c4; start: 5; end: 10).
b addEntry: (RTTimeLineEntry new identifier: #c5; start: 5; end: 8).
d := RTVerticalTickLineDecorator new.
d shape line color: Color white.
b addDecorator: d.
b axisX
numberOfLabels: 5;
labelRotation: -45;
labelConversion: [ :v | Date year: 2015 day: v ].
b shape color: (RTMultiLinearColorForIdentity new objects: b entries).
b
-=-=-=-=-=-=-=-=-=-=-=-=
One color per timeline
-=-=-=-=-=-=-=-=-=-=-=-=
| b |
b := RTTimeLine new.
b addEntry: (RTTimeLineEntry new identifier: #c1; start: 0; end: 5).
b addEntry: (RTTimeLineEntry new identifier: #c1; start: 6; end: 8).
b addEntry: (RTTimeLineEntry new identifier: #c2; start: 0; end: 5).
b addEntry: (RTTimeLineEntry new identifier: #c2; start: 8; end: 10).
b addEntry: (RTTimeLineEntry new identifier: #c3; start: 0; end: 10).
b addEntry: (RTTimeLineEntry new identifier: #c4; start: 5; end: 10).
b addEntry: (RTTimeLineEntry new identifier: #c5; start: 5; end: 8).
d := RTVerticalTickLineDecorator new.
d shape line color: Color white.
b addDecorator: d.
b axisX
numberOfLabels: 5;
labelRotation: -45;
labelConversion: [ :v | Date year: 2015 day: v ].
b shape color: (RTMultiLinearColorForIdentity new command: #identifier; objects: #(c1 c2 c3 c4 c5)).
b
-=-=-=-=-=-=-=-=-=-=-=-=
Age of some classes:
-=-=-=-=-=-=-=-=-=-=-=-=
| b |
b := RTTimeLine new.
b extent: 500 @ 500.
((RTShape withAllSubclasses sortedAs: #ageInDaysRounded) select: #hasMethods)
do: [ :cls |
e := RTTimeLineEntry new.
e identifier: cls.
e start: cls computeYoungestMethod ageInDays.
e end: cls computeOldestMethod ageInDays.
b addEntry: e ].
b
-=-=-=-=-=-=-=-=-=-=-=-=
All these examples are in the Roassal time line example menu.
This is still an early version. Let us know how it goes!
