Text Diff
by Luc Fabresse Oct. 18, 2012

Oct. 18, 2012

Hi All, I tried to do a text diff using DiffMorph. But if compared strings contain CR character, the display seems not be accurate. Example: s1 := 'ab', String space, String cr, 'd', String space, String cr, 'ef'. s2 := 'ab', String cr, 'd', String cr, 'ef'. (DiffMorph from: s1 to: s2) openInWindow. In this example, d (on line 2) is highlighted while it should not IMHO. I track this until (a DiffMorph uses a TextDiffBuilder): TextDiffBuilder>>buildPatchSequence ^Array streamContents: [ :stream | self patchSequenceDoIfMatch: [ :string | stream nextPut: #match -> (string copyWithout: Character cr) ] ifInsert: [ :string | stream nextPut: #insert -> (string copyWithout: Character cr) ] ifRemove: [ :string | stream nextPut: #remove -> (string copyWithout: Character cr) ] ] My question: why ignoring Character cr? Should we change it? #Luc

Hellp + PostgreSQL Connector
by roberto.minelli＠usi.ch Oct. 18, 2012

Oct. 18, 2012

Hello, I am Roberto Minelli, a PhD student in the REVEAL research group at the Faculty of Informatics of the University of Lugano. I am exploring Smalltalk, and Pharo, for the first time and I am open to suggestions and tips & trick. Shortly I would like to work on something concrete to get in touch with Smalltalk. One of the things I am interested in, is retrieving entries from an existing PostgreSQL database. To this aim it would be great if some to you could point me in the right direction. ;) I also heard that there are some very cool "extensions" to the Pharo IDE (i.e., code completion, code browsing, etc). I would be glad if some of you could help me discovering all these cool features of Pharo! Thanks in advance, Roberto M.

OrderedCollection detect: <- exception if not found?
by sergio_101 Oct. 16, 2012

Oct. 16, 2012

i had a problem earlier, thinking that if i did a detect: on an ordered collection, and the item was not found, i would get back nil. it turns out that it throws an error.. to get this to work, you use: detect:ifNone: my only question is... why is this so? what is the motivation behind throwing an error rather than returning nil? i guess i would like to understand the 'smalltalkiness' about this, just in case i run into something like this in the future.. thanks! -- ---- peace, sergio photographer, journalist, visionary http://www.ThoseOptimizeGuys.com http://www.CodingForHire.com http://www.coffee-black.com http://www.painlessfrugality.com http://www.twitter.com/sergio_101 http://www.facebook.com/sergio101

SUnit - works in its own space?
by sergio_101 Oct. 16, 2012

Oct. 16, 2012

a quick question on SUnit.. do tests run in their own space? say i have a model like User.. User has a class variable that is an ordered collection of of users.. User userList <- should give me and ordered collection.. in my tests, if i add users to User userList.. then, in a workspace, i inspect: User userList later, i see that my tests users have in fact been added to the ordered collection.. is this expected? thanks! -- ---- peace, sergio photographer, journalist, visionary http://www.ThoseOptimizeGuys.com http://www.CodingForHire.com http://www.coffee-black.com http://www.painlessfrugality.com http://www.twitter.com/sergio_101 http://www.facebook.com/sergio101

subscribe on system change
by Miguel Enrique Campusano Araya Oct. 16, 2012

Oct. 16, 2012

I want to do some logic when there is a change on the system, like when a new class is loaded or when a method change. I don't want to put this logic explicit on the methods of the system who do that. I would like to know if i could subscribe to those special events (method change, new method, changes on a class and so on) so I can do what I want outside those methods. I heard about the Announcements but I don't know if Announcements could help with this problem. Can anyone give me some highlights to do those things? Thanks! (I'm really trying with my english, hope it's understandable) -- Miguel Enrique Campusano Araya Estudiante de IngenierÃa Civil en ComputaciÃ³n Universidad de Chile

about Metacello package loading order
by Usman Bhatti Oct. 15, 2012

Oct. 15, 2012

I have a configuration as follows : spec for: #common do: [ "a class in package BBB inherits from a class in package AAA" spec package: 'AAA'; package: 'BBB' with: [spec requires: 'AAA'] ]. Now, when I try to load this configuration, it fails to properly load the package BBB (there are some missing classes) with this msg: *This package depends on the following classes:* * A class in package AAA* *You must resolve these dependencies before you will be able to load these definitions: A class in package BBB.* It seems that there is a way to load packages in a linear order ( http://code.google.com/p/metacello/wiki/FAQ#Controlling_Package_Initializat…) However, my project defaults is already set to linear and after reading this post my problem is not resolved. Can anyone help me how I can enforce package AAA to load before BBB? tx, usman
