Monticello - break up a package
by Ingo Hohmann April 27, 2013

April 27, 2013

Following up on my quest to get SandstoneDb to run on Pharo 2.0. Ramon asked me to break out my changes to the file store into another package, so that it is possible to just use the appropriate package for different Smalltalk versions. Now, how do I best do that? When I tried it before, I got a new package with no acestors, but the same content still in the "base" package. Thank you for your help so far. Kind regards, Ingo

Highlighter PetitParser
by Jesus NuÃ±ez April 26, 2013

April 26, 2013

Hello everybody, The following code highlights prolog code statically making use of PPTextHighlighter, I leave the code to share with the community since it might be of help to someone else. Could someone point out how can this be converted to its dynamic counterpart?; The keystroke handler for GLMTextPresentation and what model is currently being used for instance to highlight smalltalk code would be very much appreciated. >From http://bergel.eu/download/Dyla2010/dyla10_submission_4.pdf I know that it might be neccesary a fuzzy highlighter as is written at the end of the code, and it is probably the right object to use but I can not figure out where to plug it. Thank beforehand, Jesus | text textRenderer textShower | text := 'p(Q,R):-q(R), unify_st(X, smalltalk_code), r(T). q(Q):-d(R). q(Q).'. textRenderer := [ PPTextHighlighter new parser: PPPrologParser new; color: 'small_atom' with: Color blue muchDarker; bold: 'small_atom'; color: 'unify_st' with: Color green muchDarker; bold: 'unify_st'; color: 'string' with: Color gray muchDarker; color: 'number' with: Color gray muchDarker; color: 'boolean' with: Color gray muchDarker; highlight: text asText. ].

April 25, 2013

Hello again, If I have an instance variable A in ClassA and I want to use it in ClassB. If I do the following in ClassB objectA := ClassA new. objectA A: "new value for A". Why doesn't this work? Isnt this calling the setter of A on the objectA ? Pharo doesn't understand it for some reason .

SandstoneDB on Pharo 2.0 - done - what next?
by Ingo Hohmann April 25, 2013

April 25, 2013

Hi, because I haven't found a version of SondstoneDB for Pharo 2.0, I have migrated it myself. All tests are green, except for 2 performance tests. Well, it's the first time I did anything on someone elses code, that's worth sharing, so I'm a little bit unsure on the etiquette, and what to do technically. Kind regards, Ingo

SandstoneDB on Pharo 2.0 - done - what next?
by Torsten Bergmann April 25, 2013

April 25, 2013

Yes - the SandstoneDb project on Squeaksource is read/write - just commit. Esteban wrote: >also, I noticed there is no "ConfigurationOfSandstoneDB"... There already is one in MetacellRepository, just look at the comments below the video: http://www.pharocasts.com/2010/04/sandstonedb-simple-activerecord-style.html I assume your package is based on "SandstoneDb-RamonLeon.148.mcz" from http://www.squeaksource.com/SandstoneDb.html If so please commit your changes so others can try. If OK we can adopt the config in "MetacellRepository" and later put it into "MetaRepoForPharo20". If in doubt just ask! Bye T.

Hi, In: Object subclass: #A instanceVariableNames: '' classVariableNames: '' poolDictionaries: '' category: 'Unclassified'. (Smalltalk at: #A) subclass: #B instanceVariableNames: '' classVariableNames: '' poolDictionaries: '' category: 'Unclassified'. Object variableSubclass: #A instanceVariableNames: '' classVariableNames: '' poolDictionaries: '' category: 'Unclassified'. ---> why do we raise the error "B cannot be recompiled"? what's the problem with reformatting subclasses automatically? best regards, Martin

Spec and e.g. hResizing:
by Sean P. DeNigris April 24, 2013

April 24, 2013

I see in the old-school layouts that it was possible to use #hResizing: {#ButtonSpec. ... #hResizing:. #spaceFill... but I'm not sure how to do that now. I tried unsuccessfully: SpecLayout composed newRow: [ :spec | spec newColumn: [ :col | col add: #myLabel; send: #hResizing: withArguments: { #shrinkWrap } ] width: 50; add: #myModel ] height: 30; yourself. I was thinking maybe #add:withSpec: had something to do with it? ----- Cheers, Sean -- View this message in context: http://forum.world.st/Spec-and-e-g-hResizing-tp4683208.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.
