ConfigurationOfMoose
by Alexandre Bergel 06 Dec '10

06 Dec '10

Hi! Doru fixed the mess with the configuration. I do not know what went wrong with my tries. Configuration must be simpler to manage in the future. There is a lot of redundancies. For example: - ConfigurationOfMoose loads Shout, Mondrian, and DSM - Mondrian loads Shout - DSM loads Moose This all should get simpler. Doru, what are the list of actions we need to do? How can we be sure that the problem we had does not appear again?

Re: question about petitparser
by Lukas Renggli 06 Dec '10

06 Dec '10

Best is to send PetitParser questions to the Moose or Pharo list. To make your parser fail you have to enforce that it consumes until the end of the stream with #end: identifier := (#letter asParser , #letter asParser star) flatten end. identifier parse: 'ffff:gggg' Also note that you can replace p , p star with p plus Lukas On 6 December 2010 10:08, Alain Plantec <alain.plantec(a)univ-brest.fr> wrote: > Hi Lukas, > > identifier := (#letter asParser , #letter asParser star) flatten. > identifier parse: 'ffff:gggg' > > returns 'ffff'. > shouldn't it raise an error because of the $: ? > > Maybe you prefer me to ask this kind of question somewhere else. > just let me know > > Cheers > Alain > > -- Lukas Renggli www.lukas-renggli.ch

problem with the debugger
by Fabrizio Perin 06 Dec '10

06 Dec '10

Hi, i got a strange error from the debugger: when the debug window appear (in my case because a test fail) i click on the method that i want to visualize and and another debug window appear saying "MessageNotUnderstood: TextMorphEditor>>blinkParen". Attached the log. Than i figure out that in the last build of Moose you cannot even open a workspace because you get the same error. Seems something starting from shout but i'm not sure. Cheers, Fabrizio

PetitParser - The Great Flatten Mystery
by Sean P. DeNigris 04 Dec '10

04 Dec '10

I am baffled... I want to turn 'I am not yet watching' into 'IAmNotYetWatching'. I got really close with: | word additionalWord parser | word := #word asParser plus flatten ==> [ :s | s capitalized ]. additionalWord := #space asParser, word ==> [ :n | n second ]. parser := (word, additionalWord star). parser parse: 'I am not yet watching'. Result: #('I' #('Am' 'Not' 'Yet' 'Watching')) So I thought, "cool, just flatten that puppy and"... not even close! I got the exact input string back! What?! ... same as above with flatten added \/ parser := (word, additionalWord star) flatten. parser parse: 'I am not yet watching'. Result: 'I am not yet watching' Where did my capitals go and how did the spaces get back in there? Thanks.

bunchCohesion
by Tudor Girba 04 Dec '10

04 Dec '10

Hi, The following test is failing: http://hudson.moosetechnology.org/job/moose-latest-dev-on-pharo-1.2/48/test… The reason it is failing is that the method bunchCohesion is not defined. I guess the appropriate code was not published. Andre, Nicolas, could you take a look? Cheers, Doru -- www.tudorgirba.com "When people care, great things can happen."

ConfigurationOfPetitParser should stay in its own repo
by Tudor Girba 03 Dec '10

03 Dec '10

Hi Alex, I see that you are working on the Moose release. That is great! Just a note: The ConfigurationOfPetitParser should remain in the repository of Lukas, and not in the repository of Moose. Could you take care of that? Cheers, Doru -- www.tudorgirba.com "It's not what we do that matters most, it's how we do it."

Re: CollectionExtension>> testFlatCollectArray needs Nile?
by Tudor Girba 03 Dec '10

03 Dec '10

Why not depend on it? I think that if we are not using Nile, all the nice work goes away. Are there any problems related to it?

Re: Question for student report
by Tudor Girba 01 Dec '10

Hi Simon, I would suggest registering to the mailing list and asking more specific questions: http://www.moosetechnology.org/about/contact I would suggest scheming through the online Moose Book. In particular I would suggest to start from the last chapter: http://www.themoosebook.org/book/philosophy Regarding the use of Smalltalk, here is a short explanation: http://www.themoosebook.org/book/introduction/smalltalk Cheers, Tudor On 1 Dec 2010, at 17:06, (s) Simon Pakijavan wrote: > Hi Tudor > > Thanks for the reply. > > I'm really interested in finding out what makes Moose such a usefull tool for data management and also why it is Smalltalk based.
