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
Hi,
Alex Syrel, Andrei Chis and I are happy to announce a new addition to the
Glamorous Toolkit:
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
Pharo.
Here is a couple of screenshots:

A trailer is available here:
https://www.youtube.com/watch?v=PhSmjR3NOlU
A detailed description is available here:
http://www.humane-assessment.com/blog/introducing-gtspotter
It works already in Pharo 3.0 and can be played with by following the
instructions from:
http://gt.moosetechnology.org
Please let us know what you think.
Enjoy,
The Glamorous Team

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,…
[View More] 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)}

Why is Fame (and Famix) statically typed?
It always seemed strange to me in the Smalltalk context.
Do we really use/need this property?
(Because sometimes, it really sucks)

Hello,
I am happy to release the Animation package at last! http://catalog.pharo.org/catalog/project/Animation
This is a general animation system, which can turn any setter message into a smooth transition (provided it has a corresponding getter, and the target value supports + and *Float).
Examples:
morph position: (100@100 during: 2 seconds easing: #backOut).
morph color: (Color red during: 2 seconds).
morph title: ('tutututu' during: 2 seconds).
I am curious to see if/how it could be used …
[View More]with Roassal/Moose. Please send any (good or bad) feedback you may have while testing it!
Cheers,
Thibault
ps: Thanks to anonymous contributor for the second syntax, it was a lot of fun - and evil laughs :)

Hi,
John and I worked a bit together and updated the following parser:
- Delphi
- C# (supports version 6.0)
- JavaScript
As you know, SmaCC is now in the Moose distribution, and it comes with detailed abstract syntax trees. This offers new opportunities for the kinds of analyses we can provide.
Cheers,
Doru

Hello,
I would like to report some random segfaults happing during the build of the Moose 6.1 image (based on Pharo 6).
Please find attached the latest failing stack trace.
Here are the 2 jobs that fails:
https://ci.inria.fr/moose/job/moose-6.1/345/consolehttps://ci.inria.fr/moose/job/moose-6.1/347/console
It seems that they are not failing for the same reason.
Maybe because the job is not using the latest VM? :

Hi,
I am happy to announce the availability of PetitParser2, a wonderful redesign of the original PetitParser developed by Jan Kurš.
https://github.com/kursjan/petitparser2
Highlights:
- it introduces the compiler facility that speeds up parsers by a factor of ~2-5x
- it introduces the possibility of parsing streams without having them in memory
- it comes with a new structure internally that makes it more flexible
- it introduces asPParser (not a typo) to be able to have the new version …
[View More]working in parallel with the classic asParser
The version is already present in the latest Moose 6.1 in parallel with PetitParser. Also, several of the parsers that are shipping with PetitParser were already copied to PetitParser2 as well.
You can find more details here:
http://www.humane-assessment.com/blog/introducing-petitparser2/
Some more documentation will follow.
I think Jan did a wonderful job and the result is quite exciting. Please take a look and let us know what you think.
Cheers,
Doru

Hi doru
If I have a model "model1" mse or database it will have internal names/id
then I have a delta or even another model
and loading it I will need to do a mapping between in memory objects of
the model 1
So you propose to remove all the entities related to entities in Model2
from model1 and to load load model2
but to do so you need to know that id:xxx in Model2 corresponds to Class
A in Model
My impression is that we should really have a uniqueName for any entity.
