Hi! We're sending this automatic email twice a month, to give the community an opportunity to easily know what's happening and to coordinate efforts. Just answer informally, and feel free to spawn discussions thereafter! ### Here's what I've been up to since the last WhatsUp: - $HEROIC_ACHIEVEMENTS_OR_DISMAL_FAILURES_OR_SIMPLE_BORING_NECESSARY_TASKS ### What's next, until 2013-09-15 (*): - $NEXT_STEPS_TOWARDS_WORLD_DOMINATION (*) we'll be expecting results by then ;)

Re: [Pharo-dev] "self foo: (var := â¦)" vs "var := â¦. self foo: var"

by Tudor Girba

As far as I know, it was the same problem that induced the Metacello loading problem related with SmallInteger.

Re: [Pharo-dev] Should Job use SystemAnnouncer?

by Camillo Bruni

I think this is a good idea, you can see that there is already an #announcer inst var that currently is unused. I think the original idea behind using the system announcer was to make other tools possible that will interact with the progress. Though nobody did it so far ;) => if it is a performance penalty remove it! Plus if there is a private announcer for each job the only announcement that really needs to go public is JobStart, from then on potential 3rd party tools can register to the internal announcer.

Should Job use SystemAnnouncer?

by Stephan Eggermont

While profiling some progressbar code, I noticed Job uses the SystemAnnouncer. It seems odd that an Announcer used for noticing code changes is reused for something unrelated to code changes. Could we have a separate announcer for this? Stephan

Re: [Pharo-dev] DSM in Roassal

by Alexandre Bergel

Hi Volkert, Yes, we started an effort on that. Consider: | view builder | view := ROView new. builder := RODependencyMatrixBuilder new. builder model: (Array with: true with: false). builder dependencyBoolean: #xor:. builder gapSize: 0. builder on: view. view open Another example: | view builder objects | objects := ROShape withAllSubclasses. view := ROView new. view @ RODraggable. builder := RODependencyMatrixBuilder new. builder model: objects. " builder noVerticalShape." builder dependency: #superclass. builder gapSize: 0. builder on: view. view open If you are working on something similar, it would be great to join forces... how to load Juraj's code: Gofer new smalltalkhubUser: 'JurajKubelka' project: 'RoassalProposals'; package: 'RoassalGraphBuilders'; load. (Smalltalk globals at: #RODependencyMatrixBuilderTest) browse. Look at the ROMatrixExample class Will you be at ESUG?

DSM in Roassal

by Volkert Barr

Dear all, i am using Roassal for visualizing applications dependencies and metrics of applications / applications clusters on enterprise architecture level. I would now do some experiments with DSM and found an older mailing list post that DSM support in Roassal is currently in development. That is cool :-) How can i tests this feature? It is not part of the latest Roassal (dev) version. Please help ... :-) BW, Volkert

this is a VM problem, Use the latest (unstable) vm from here: http://files.pharo.org/vm/pharo/ Esteban updated the VM On 2013-09-01, at 15:02, Alexandre Bergel <alexandre.bergel(a)me.com> wrote: > Hi! > > I am facing a strange situation: > > The following expression raises an error: > -=-=-=-=-=-=-=-=-= > rawView add: (helpLabel := (ROElement on: 'Click here!') + ROLabel). > -=-=-=-=-=-=-=-=-= > > Apparently, what is sent as argument to #add: is an integer. > > I have to update my code with : > -=-=-=-=-=-=-=-=-= > (helpLabel := (ROElement on: 'Click here!') + ROLabel). > rawView add: helpLabel. > -=-=-=-=-=-=-=-=-= > > To not have an error. > > This is really strange!

"self foo: (var := â¦)" vs "var := â¦. self foo: var"

by Alexandre Bergel

Hi! I am facing a strange situation: The following expression raises an error: -=-=-=-=-=-=-=-=-= rawView add: (helpLabel := (ROElement on: 'Click here!') + ROLabel). -=-=-=-=-=-=-=-=-= Apparently, what is sent as argument to #add: is an integer. I have to update my code with : -=-=-=-=-=-=-=-=-= (helpLabel := (ROElement on: 'Click here!') + ROLabel). rawView add: helpLabel. -=-=-=-=-=-=-=-=-= To not have an error. This is really strange! By the way, this looks like the issue with Metacello?

TalkFFI versions 1.3 and 1.4

by Guillermo Polito

Hi Ciprian, In the last weeks we were playing a bit with TalkFFI for dbxtalk. After a while we got a working version but we found some stuff we'd like to fix. In version 1.3 CLExternalLibraryWrapper class>>uniqueInstance is wrongly defined. This is already fixed in talkffi 1.4. However, version 1.4 includes some other changes that make the VM just crash, :). What do you think about making a 1.3.1 version with the minor fix for the unique instance so we can move on without overrides? Of course I'm happy to provide the code (given the credentials to commit :)). TIA, Guille
