reflection examples

by Torsten Bergmann

Ask someone from another language how they count their tests classes. In Smalltalk you can easily: TestCase allSubclasses size or write other nice statistics scripts about your programs. Reflection can be used to find an appropriate selector when you know the input and the result. I'm sure you know that features available in the finder tool: 3. 4. 7. or according examples from the finder tool like: MethodFinder methodFor: #( (4 3) 7 (0 5) 5 (5 5) 10). Maybe the PragmaCollector is also a nice example: just define a method foo <todo> ... and then: (PragmaCollector filter: [:pragma | #todo = pragma keyword]) reset collected Also have a look at "Teachable" from config browser. It's not directly related to reflection but shows how easy it is to use #doesNotUnderstand and write mocks. One can do other nice tricks - like implement a getter automagically when it is not there, ... Beware - you already know the "true become: false" trick ;)

Cool... Worst-case scenario, it seems that a taxi would be 100 euros or less, so if we can get three or four people, it would actually be pretty cheap!

reflection examples

by Tudor Girba

Hi, I am preparing a set of talks that have reflection at the center. Obviously, I want to use Pharo to demonstrate reflection. I am now looking for examples that can be explained to programmer newbies (actually, managers). I am particularly looking for examples that include adaptation (not just inspection) and that can show that reflection is valuable. I already have some examples in mind, but they might not appear particularly valuable. For example: - inspecting a class: Object methods. - adapting a class: Object compile: 'answer ^ 42'. Any suggestions? Cheers, Doru -- www.tudorgirba.com "Every thing has its own flow"

Camp Smalltalk Roadtrip!

by DeNigris Sean

(cross-posted to pharo dev and esug lists) Countdown to ESUG!!! My plane lands in Geneva at 1020 on 8 September. I was planning on taking the bus to Annecy, but apparently there is only one bus that Sunday, which arrives at 2200. Is anyone traveling that morning from the direction of Geneva who would like to team up e.g. share a taxi, meet somewhere along the way, etc? Thanks! Sean

Sticky Morph ?

by Erwan Douaille

Hi, I'm looking for "sticky" morph. I means, i would like an automatic alignment when 2 morphs are close both of them. There is already something existing ? I need it for the UIPainter canvas to make alignment more easier than trying to move mouse when moprh are close to 1 pixel. Thanks for helping :) -- Best regards, Douaille Erwan <douaille.erwan(a)gmail.com>

can you add a bug tracker entry?

Re: [Pharo-dev] Put issues from cog issue tracker into pharo issue tracker

by Nicolas Cellier

Reporting bugs on fogbugz is not a problem for me. However, the main concern I have is about the efficiency of these reports... Will Eliot have access to these reports and use them for his oscog branch? Will David have access for backporting some common bugs to interpreter VM? Will the reports be mailed to vm-dev? After all, I'm not really sure how the old bug tracker was usefull for oscog or interpreter VM... But I have the feeling that the reports on fogbugz will be for Pharo VM branch only. I'm very happy if I can be usefull to Pharo. But I'm even more if I can be usefull to Squeak/Cuis too for the same price, so I feel the move a bit like a loss.
