reviewing moose chef
by Tudor Girba 29 Apr '11

29 Apr '11

Hi, I am going over Moose Chef. It's quite cool :). Here are some issues I found: 1. MooseQueryResult currently inherits from Collection. It would be more useful if it would be a MooseGroup because we could directly navigate it in the Moose Finder. I already played with it and it looks like it is not too problematic to get this working. I got 237 of 240 tests green. The 3 left are due to the Composite not working quite properly due to a small mismatch between the semantics of Group and Collection. Is there a reason for why we would want a Collection? If not, I will try to get it fully working and then commit. 2. I like the filters, but they would need to be extended for handling groups of entities. For example, now we can say outOfPackage:, but we should also be allowed to specify outOfPackages:. This should not be hard. 3. Right now, we can work with one entity as a starting point (namespace, package, class or method). We should also be able to have Groups as starting point. For this, I guess we would need some other Traits. 4. There are two references to MooseCompositeQueryResult in TScopingEntityQueries and in TDependencyQueries. This class does not exist. First these methods seem to be overridden in the classes. Second, I guess it should be MooseOutgoingCompositeQueryResult. Am I correct?

Petit parser and negation
by Norbert Hartl 28 Apr '11

28 Apr '11

I'm trying to parse a negated character with petit parser. I'm trying to parse [^"]* but the only thing I came up with is ($" asParser not, #any asParser) star flatten Is there a better way to parse it or is this just the way to go? The not consuming not parser is indeed useful if I need a combination of negation but the straight forward thing I try to solve looks cumbersome. thanks, Norbert

Re: Question on Moose
by Alexandre Bergel 28 Apr '11

So far no. I have worked with databases, so I cannot recommend anything. However, if you can extract the data "by hand" and produce a textual file (or even better, an XML file), then the battle will be easily win.

Moose vs KDM
by Michele Lanza 28 Apr '11

28 Apr '11

Dear all, recently I've come across the KDM (Knowledge Discovery Metamodel) on a couple of occasions. KDM is defined by its maker OMG as "a common intermediate representation for existing software systems and their operating environments, that defines common metadata required for deep semantic integration of Application Lifecycle Management tools". See http://www.omg.org/technology/kdm/index.htm and http://www.omg.org/spec/KDM/1.0/PDF/ Reverse engineering tools are cropping up claiming they're KDM-compatible (whatever that means). I must admit I was not aware of KDM up until very recently, although it seems to have been around since 2008. My question is: is any Mooser looking into KDM? If not it might be worth a shot, even if only for a Bachelor project, just to understand what is there and what it could mean for Moose. Cheers Michele PS. This is not a "please look into it" message, as I can already anticipate a "why the hell don't you do it yourself" reply. It's a general "heads up" about something that may impact Moose in some way. In any case, I'll try to find a student willing to look into this.

how to deal with string position in relation to cr/crlf
by Tudor Girba 28 Apr '11

28 Apr '11

Hi, I have a small problem related to file line endings and storing the token information of PetitParser. Sometimes, we parse the sources on Windows and then manipulate the model on Linux or Mac. In this context, if I store the token positions in a string, I encounter problems because CR and LF are considered characters, but the line endings can vary. ('abc', Character cr asString , 'd') findString: 'd'. ==> 5 ('abc', Character cr asString , Character lf asString, 'd') findString: 'd'. ==> 6 How would you approach this problem? Cheers, Doru -- www.tudorgirba.com "Every thing has its own flow."

roeltyper problem
by Tudor Girba 27 Apr '11

27 Apr '11

Hi, I am trying to use RoelTyper, but I encountered subscript out of bounds and empty collection errors. It looks like this problem can be reproduced on 29 classes from Pharo 1.2.1. You can test it using: classes := Dictionary new. Object withAllSubclassesDo: [:each | [(TypeCollector typeInstvarsOfClass: each )] on: Error do: [:error | classes at: each put: error ]]. classes inspect I am not knowledgeable enough to dive into this. Can anyone help? Cheers, Doru -- www.tudorgirba.com "Value is always contextual."

Fame C# implementation
by Usman Bhatti 27 Apr '11

27 Apr '11

I sent this msg to Fame-dev but it seems that the list is no more active. ---------- Forwarded message ---------- From: Usman Bhatti <me(a)gmail.com> Date: Tue, Apr 26, 2011 at 6:22 PM Subject: Fame C# implementation To: fame-dev(a)iam.unibe.ch <https://mail.google.com/>Hi all, I am working on extracting C# information and import that into Moose. I am looking to automate the creation of Famix 3.0 entities in C# code to fill in the information and export those entities into MSE file. I've seen that there is a C# solution for Fame similar to Java on the fame page<http://scg.unibe.ch/wiki/projects/fame/>. However, C# solution does not include code for the generation of Famix 3.0 entities in code as the code does. My question is: does the C# solution for fame support the import of FAMIX 3.0 entities thru automated code generation as it does for java? thanx a lot, Usman

Re: [Metacello] MetacelloBrowser ui...
by Dale Henrichs 27 Apr '11

Hello Nick, So then the cut-point is at the level of message sends between the GUI and the model? How are events handled (messages from the model to the GUI) ... this is the spot where I think that OmniBrowser (in the GLASS implementation) started to falter ... there a large number of event messages that end up with more network round trips than one would like ... It seems that there is a need for some sort of "message concentrator" that cuts down on network round trips, but this is wandering into "early optimization" territory:) I think it would definitely be interesting to give this a try with GemStone as it has the potential to provide much more flexibility in terms of which GUI components can be used ....

Hopefully in your case too. http://www.squeaksource.com/@69jY6Xu1NHtRD19j/lOHxDstw So if your scenario is this: You already have or you are creating a tool with Model-View architecture that plays well when tested locally on a client and you want to go remote. Then with rST (hopefully) you just wrap your model in a network proxy and everything plays out of the box remotely. At least this is our goal.. we are currently working with remote reflection (in a more theoretical sense) but we should and will find time to make rST more robust for the community. I hope this helped, a bit.

Hi, This is the default way to load the latest version: Gofer new squeaksource: 'Glamour'; package: 'ConfigurationOfGlamourSeaside'; load. (Smalltalk at: #ConfigurationOfGlamourSeaside) loadDefault.
