Re: [Pharo-dev] Spec Examples

What should be done is to first create some methods on ComposableModel like instantiateListModel, instantiateTextModel, etc so you hide at maximum the implementation details, and then you can do a more generic "self instantiate: MethodBrowser." The first version of Spec was like this: > listModel := self instantiate: ListComposableModel. > methodModel := self instantiate: MethodBrowser. But then you find out there is always the same pattern, so Johan and I decided to introduce a way to encapsulate this. Then of course, do whatever you want :P Ben On Sep 21, 2013, at 7:29 PM, Camillo Bruni <camillobruni(a)gmail.com> wrote: > Can I rewrite all spec examples from > > self instantiateModels: #( > listModel ListComposableModel > methodModel MethodBrowser ). > > to the more explicit form: > > listModel := self instantiate: ListComposableModel. > methodModel := self instantiate: MethodBrowser. > >

I remember vaguely that the UI framework under NetBeans did these kind of methods in Java...

PostgresV2 overrides

by Esteban A. Maringolo

I loaded GlorpDBX configuration from the MetacelloRepository using: ((Smalltalk at: #ConfigurationOfGlorpDBX) project version: '2.5') load. ((Smalltalk at: #ConfigurationOfGlorpDBX) project version: '2.5') load: 'GlorpPostgresV2Native'. But the PostgresV2 package basically f*cks up the DateAndTime class overriding #julianDayNumber and #offset: Is this normal behavior? I'm loading a vanilla 2.0 image to see if this also happens there. Esteban A. Maringolo

Since UIPainter, example aren't needed :p Another way, than i like, is create a method for a model. Class>>listModel listModel ifNil: [ listModel := self instantiate: ListModel. and options ]. ^ listModel And do nothing in initializeWidgets 2013/9/21 Camillo Bruni <camillobruni(a)gmail.com> > Can I rewrite all spec examples from > > self instantiateModels: #( > listModel ListComposableModel > methodModel MethodBrowser ). > > to the more explicit form: > > listModel := self instantiate: ListComposableModel. > methodModel := self instantiate: MethodBrowser. > > > -- Best regards, Douaille Erwan <douaille.erwan(a)gmail.com>

Spec Examples

by Camillo Bruni

Can I rewrite all spec examples from self instantiateModels: #( listModel ListComposableModel methodModel MethodBrowser ). to the more explicit form: listModel := self instantiate: ListComposableModel. methodModel := self instantiate: MethodBrowser.
