do-it shortcut unification
by Peter Uhnák 09 Mar '15

09 Mar '15

Hi, I find it quite confusing that there is always different shortcut for do it: * Playground: alt + shift + g * Inspector: alt + g * Roassal Easel: alt + s Can this be unified? Peter

smaller configurations vs groups [was Re: Pillar and GT tools in Pharo4]
by Tudor Girba 08 Mar '15

08 Mar '15

Hi, I summarize below why I think fine grained configurations should be preferred to groups. The group is not a first class configuration, although it can be depended on. If you depend on a group of a configuration, it's harder to understand the consequences and it's harder to build tools for it. Consider the graph below representing the dependencies starting from ConfigurationOfMoose #development: [image: Inline image 2] It's a simple representation of dependencies, and it makes the maze of configurations easier to grasp. The interesting thing about it is that by showing a configuration node only once, you can see how multiple other projects depend on it. For example, HashTable is being depended on by two distinct configurations. You can also see that Magritte depends on Grease, but you do not see that it only depends on the Core group. To do that, you have to look at the details of the edge. We used to have groups in GT, however, after a while we moved to more fine grained configurations. As a consequence, you can see that GlamourCore (which used to be a group in Glamour) is being depended on by three different configurations. Using first class configurations makes tool building (like representation, navigation or release) easier. You could argue that we could represent a Group as node, however, even then you would not be able to see dependencies between groups that reside within the same configuration because groups are not first class configurations that can explicitly define dependencies, they are just groups. Groups might provide an apparent ease of use for quick things, but I strongly believe that they are an unessential construct and that if we would not use them, tools would become cheaper and more effective.

Fwd: [Pharo-users] Reading an SQL db on OS X
by Alexandre Bergel 07 Mar '15

07 Mar '15

Hi! I am forwarding Pierce’s answer to the mailing list. I think it may interest some people. I was able to open and query a SQL database (.db file). It works nicely. Just to let you know.

MooseModel>>numberOfPackages ?
by Alexandre Bergel 07 Mar '15

07 Mar '15

Hi! There is the following method in Moose: -=-=-=-=-=-=-=-=-=-=-=-= MooseModel>>numberOfPackages <MSEProperty: #numberOfPackages type: #Number> <MSEComment: 'Total number of packages'> ^ self isSmalltalk ifTrue: [self privateState propertyAt: #numberOfPackages ifAbsentPut: [self allPackages size].] ifFalse: [self privateState propertyAt: #numberOfPackages ifAbsentPut: [self allNamespaces size].]. -=-=-=-=-=-=-=-=-=-=-=-= The fact this method is defined in MooseModel seems quite wrong to me. Why should this method be in that class? #numberOfClasses is defined somewhere else. I now have a moose model that contains profiling data, and the notion of package is meaningless in my context.

GT Inspector: Fit Morphs
by Sean P. DeNigris 06 Mar '15

06 Mar '15

What if we scaled Morphs (e.g. image previews) to fit in the tool? Right now, panes showing Morphs show them clipped with no scroll bars, which is less useful for large images. ----- Cheers, Sean -- View this message in context: http://forum.world.st/GT-Inspector-Fit-Morphs-tp4810050.html Sent from the Moose mailing list archive at Nabble.com.

GT Inspector: Edit Inst Var Value
by Sean P. DeNigris 06 Mar '15

06 Mar '15

In the old inspector, you used to be able to do this by accepting the right pane. Is this possible with GT Inspector? Thanks. p.s. I'm assuming since I didn't see a user list that this is the place for user questions as well as dev stuff. Is that correct? ----- Cheers, Sean -- View this message in context: http://forum.world.st/GT-Inspector-Edit-Inst-Var-Value-tp4810059.html Sent from the Moose mailing list archive at Nabble.com.

Simple question about blueprint complexity visualization
by Sebastian Tleye 06 Mar '15

06 Mar '15

Hi all, I am trying to analyze my system by using moose and creating a BluePrint Complexity Visualization. The problem is that the visualization is a morph without zoom or drag and is difficult to understand something. Is there any way to have a visualization like the one of "System Complexity"? (In which is possible to drag, to zoom and to export) Thanks

embedded tutorial?
by Alexandre Bergel 06 Mar '15

06 Mar '15

Hi! Someone in the room today tried Moose. He browsed the moose website and downloaded the latest moose. He then opened it and started to click around. He closed it and moved to something else. I think this is a quite representative behavior. After having downloaded Moose, the next step is not clear at all. Maybe having a welcome message and some tutorials available could help?
