[Glamour] default selection in ListPresentation
by Cyrille Delaunay
Hello,
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|
tmpBrowser := GLMTabulator new.
tmpBrowser row: #list.
tmpBrowser transmit to: #list; andShow: [:a |
a list
display: [:input | input];
selection: #a;
yourself
].
tmpBrowser openOn: #( b c d v a d f r).
but the list still open with nothing selected

A quick analyzis of the usage of instance variables in Moose
by Guillaume Larcheveque
Hi Moose users,
as you may know, at Synectique we experiment lots of issues about memory
usage.
That's why i had a look at the number of unused instance variables in one
of our system loaded with a big model from one of our main customer.
Total instance variables: 26.852.653
Used instance variables: 17.393.938
Empty collections: 5.023.508
Recoverable instance variables: 14.482.223
The recoverable instance variables are those with nil or an empty
collection (or MultiValueLink)
As you can see, we can save a lot of memory :-)
Here is my (dirty) code to get that:
countUsedInstanceVariableInForSubInstances: aClass
| usedInstNbr instNbr emptyCollNbr |
usedInstNbr := 0.
instNbr := 0.
emptyCollNbr := 0.
aClass
allSubInstancesDo: [ :anEntity |
instNbr := instNbr + anEntity class allInstVarNames size.
anEntity class allInstVarNames
doWithIndex: [ :e :i |
(anEntity instVarAt: i)
ifNotNil: [ :content |
([
content isEmpty.
emptyCollNbr := emptyCollNbr + 1.
false ]
on: MessageNotUnderstood
do: [ false ])
ifFalse: [ usedInstNbr := usedInstNbr + 1 ] ] ] ].
^ {('Used instance variables' -> usedInstNbr).
('empty collections' -> emptyCollNbr).
('Recoverable instance variables' -> (instNbr - (usedInstNbr -
emptyCollNbr))).
('Total instance variables' -> instNbr)}

Roassal examples browser - too many items
by Ben Coman
Just some quick feedback... in the "Moose Suite 6.0 (beta)" image from
PharoLauncher I opened World > Roassal > Roasasal Examples
Nice interface, but for the category "Grapher - Overall" I find there are
too many items,
such that even the text labels are too small to read. It might be better
to split this out to a few more categories.

ElasticBoxZoom
by Ben Coman
I loaded Roassal into Pharo 60411 and tried #exampleElasticBoxZoom.
I select a major portion of the graph, but it zooms down onto one of the
tiny axis tick-marks. Is there an issue tracker that is a better place to
report this?
cheers -ben
P.S. I was trying to run Moose 6.0 (beta) from Pharo Launcher on top of
a recent VM Feb 22 2017. It was locking up and crashing and I wasn't sure
how the versions aligned, so switching to loading Roassal from catalog
into 60411 has been running fine.

GTInspector duplicates overriden extensions
by Peter Uhnak
Hi,
when I override a method with a GTInspector (because I need to change it),
then inspector contains the extension twice.
It seems Inspector scans the whole hierarchy of the inspected object for methods, but doesn't deduplicate them.

CK metrics from Moose? (was Re: Publications of projects using Moose?)
by Cris Fuhrman
Hello!
I'm wondering if it's in the scope of Moose to get to the standard CK
metrics for a model? It seems it's been done experimentally (
https://pdfs.semanticscholar.org/0eb2/14ec7c6288dc13564580beafc2609b09118...)
and I also found the momfe paper from 2002 (
http://scg.unibe.ch/archive/projects/Bute02a.pdf) but appeared not to have
all the CK metrics.
I also found the right-click on a Moose Model -> Export -> Export model to
MSE, but there was nothing that looked like standard CK metrics in the
exported file.
We are particularly trying to generate CBO (for a research comparison) for
a few classes and would like to be able to do all our work in Moose if
possible (especially with the visualizations in a RTView).
Cheers,
C. Fuhrman

Position of #numberOfLinesOfCode in hierarchy
by Cyril Ferlicot D.
Hello everyone,
I found something I find odd today. The method #numberOfLinesOfCodes is
defined on the Behavioral entities. I would have expected it on the
Sourced entities because if an entity has sources it should have a
number of lines of code.
What do you think?

How ready is Bloc for a simple use-case?
by Peter Uhnak
Hi,
I wanted to ask about Bloc:
1) how stable is the API? e.g. if some overhaul changes to unify/whatever are planned
2) I saw in the techtalk that you can align elements (to center, bottom, ...), however is that possible with lines? Lines have to rotate, morph shape, etc.
3) Are non-straight lines possible? (e.g. bezier, arc)
The idea for me is to make a simple mindmap
- elements with some text, icons, math symbols inside
- connectors (non-straight lines) between elements
To me (apart from the lines) it seems like it should be already doable.
Also either my (Morphic) Pharo is really slow, or Bloc (in the video) is superfast (everything is happening instantly).
Thanks,
Peter
