Thanks. And do you have an idea of better groups that the basic ones I have defined? (look at the end). I mean, imagine groups of packages that it is likely a user will load only them, and all together spec for: #pharo do: [ spec repository: 'http://www.squeaksource.com/rb'. spec package: 'AST-Core'; package: 'AST-Tests-Core' with: [ spec requires: 'AST-Core' ]; package: 'AST-Semantic' with: [ spec requires: 'AST-Core' ]; package: 'AST-Tests-Semantic' with: [ spec requires: 'AST-Semantic' ]; package: 'Refactoring-Environment' with: [ spec requires: 'AST-Core' ]; package: 'Refactoring-Tests-Environment' with: [ spec requires: 'Refactoring-Environment' ]; package: 'Refactoring-Changes' with: [ spec requires: 'Refactoring-Environment' ]; package: 'Refactoring-Tests-Changes' with: [ spec requires: 'Refactoring-Changes' ]; package: 'Refactoring-Core' with: [ spec requires: 'Refactoring-Changes' ]; package: 'Refactoring-Tests-Core' with: [ spec requires: 'Refactoring-Core' ]; package: 'Refactoring-Critics' with: [ spec requires: 'Refactoring-Changes' ]; package: 'Refactoring-Tests-Critics' with: [ spec requires: 'Refactoring-Critics' ]; package: 'Refactoring-Spelling' with: [ spec requires: 'Refactoring-Critics'. spec postLoadDoIt: #postLoadRBSpelling ]; package: 'Refactoring-Tests-Spelling' with: [ spec requires: 'Refactoring-Tests-Critics'. ]. spec group: 'default' with: #('Core' ); group: 'Core' with: #( 'AST-Core' 'AST-Semantic' 'Refactoring-Environment' 'Refactoring-Changes' 'Refactoring-Core' 'Refactoring-Critics' 'Refactoring-Spelling' ); group: 'Tests' with: #( 'AST-Tests-Core' 'AST-Tests-Semantic' 'Refactoring-Tests-Environment' 'Refactoring-Tests-Changes' 'Refactoring-Tests-Core' 'Refactoring-Tests-Critics' 'Refactoring-Tests-Spelling' ); group: 'Core Tests' with: #('Core' 'Tests' ); cheers mariano On Sat, Sep 25, 2010 at 10:18 PM, Lukas Renggli <renggli(a)gmail.com> wrote: > Refactoring-Spelling depends on Refactoring-Critics. > Refactoring-Tests-Spelling depends on Refactoring-Tests-Critics. > > Lukas > > 2010/9/25 Mariano Martinez Peck <marianopeck(a)gmail.com>: > > > > > > 2010/9/5 Lukas Renggli <renggli(a)gmail.com> > >> > >> I've split the refactoring model into various packages as outlined in > >> the previous mail. > >> > >> The dependencies between the tests are slightly problematic, but will > >> eventually be fixed as depicted in red in the attached dependency > >> graph.

I do not know. I would like to know whether the change propagates. can you do the following: - load the package - modify one method - save it - reload it in another image and you get them all dirty? In which image? do you see changes related to methodReference or timestamp? I know that the SUnit code niall sent us does not contain all the source code and that the binary is different from the source code. we should investigate that.

[Pharo-project] In Smalltalk you can't loose code... hum

by FranÃ§ois Tanguy

Hi, the statement is true when the code is saved in the browser. But in a workspace or in the script manager that is not true. Actually it is a feature request: You can't loose code even when you are working in the script browser. Because in the script manager has a save capability, would it be difficult to write the changes into the changes files ? Francois
