do we need to debug testmethods from within Nautilus ?

by Nicolai Hess

Issue: 14060 <https://pharo.fogbugz.com/default.asp?14060> MNU: receiver of "stepToCallee" is nil I suggest we remove this method from nautilus. If we really want to provide such a feature, the implementation should go to TestCase and/or Context. The SystemBrowser should not tinker with processes and manipulate context stacks. Or is there a way to (programmatic) set a break point (halt) and just execute the method?

GSOC 2015 Call for Ideas

by Serge Stinckwich

Dear pharoers, this year Pharo consortium (and community) is going to take part in a Google Summer of Code event[1] as a standalone organization. This is an opportunity to promote Pharo, get some job done and have students paid. Currently we are at the most important stage as we are preparing the organization application, and hoping that we will be accepted and granted decent amount of project slots. Everyone can help with application by submitting ideas for student projects. Current list can be found at: https://github.com/pharo-project/pharo-project-proposals/blob/master/Topics… It is in STON format, and result is being generated at: http://gsoc.pharo.org/ Please add your ideas following the format of existing projects and open a pull request with them (you will need a github account). Preferably submit ideas with possible mentors, but if none are available at the moment ideas without mentors are also welcome. The template to submit projects is : PharoTopic new title: 'The name of your project; contact: 'email address'; supervisors: 'Supervisors names'; keywords: 'keywords separated by spaces; context: 'a description of the context of the project'; goal: 'description of the goal'; level: 'Beginner or Intermediate or Advanced'; yourself. We will need a lot of projects/idea before February 20th 2015, the deadline for applying to GSOC 2015. Do not hesitate to ask questions. Administrators of this yearâs application are Serge Stinckwich <serge.stinckwich(a)gmail.com> and Yuriy Tymchuk <yuriy.tymchuk(a)me.com> If you don't know how to edit the list, please send your project following the template to the administrators.

Re: [Pharo-dev] About Matrix API access

by stepharo

this is correct | matrix23 | matrix23 := Matrix rows: 3 columns: 2. matrix23 at: 1 at: 1 put: 11. is equivalent to | matrix23 | matrix23 := Matrix rows: 3 columns: 2. matrix23 at: 1 atRow: 1 putColumn: 11. In ruby [i,j] Returns element (i,j) of the matrix. That is: row i, column j. This is strange that we cannot map i to x and j to y position and that i is in fact mapped to y > Hi > > > I'm wondering why > > | matrix23 | > matrix23 := Matrix rows: 3 columns: 2. > matrix23 at: 1 at: 1 put: 11. > matrix23 at: 1 at: 2 put: 12. > matrix23 at: 1 at: 3 put: 13. > matrix23 at: 2 at: 1 put: 21. > matrix23 at: 2 at: 2 put: 22. > matrix23 at: 2 at: 3 put: 23. > > is not equivalent to > > | matrix23 | > matrix23 := Matrix rows: 3 columns: 2. > matrix23 atColumn: 1 atRow: 1 put: 11. > matrix23 atColumn: 1 atRow: 2 put: 12. > matrix23 atColumn: 1 atRow: 3 put: 13. > matrix23 atColumn: 2 atRow: 1 put: 21. > matrix23 atColumn: 2 atRow: 2 put: 22. > ^ matrix23 atColumn: 2 atRow: 3 put: 23 > > I always thought that math notation was x,y (row,colum) > How is it done in other languages? > I checked the implementation so I know but why this choice in the API. > > > >

About Matrix API access

by stepharo

Hi I'm wondering why | matrix23 | matrix23 := Matrix rows: 3 columns: 2. matrix23 at: 1 at: 1 put: 11. matrix23 at: 1 at: 2 put: 12. matrix23 at: 1 at: 3 put: 13. matrix23 at: 2 at: 1 put: 21. matrix23 at: 2 at: 2 put: 22. matrix23 at: 2 at: 3 put: 23. is not equivalent to | matrix23 | matrix23 := Matrix rows: 3 columns: 2. matrix23 atColumn: 1 atRow: 1 put: 11. matrix23 atColumn: 1 atRow: 2 put: 12. matrix23 atColumn: 1 atRow: 3 put: 13. matrix23 atColumn: 2 atRow: 1 put: 21. matrix23 atColumn: 2 atRow: 2 put: 22. ^ matrix23 atColumn: 2 atRow: 3 put: 23 I always thought that math notation was x,y (row,colum) How is it done in other languages? I checked the implementation so I know but why this choice in the API.

Thank you all. I'm learning so I will revise all the comments and arguments.
