[ANN] SeasideTesting recovered from oblivion

by Esteban Lorenzano

Hi, I spend some days last week woking with the guys of AFI (http://afi-sa.fr <http://afi-sa.fr/>, yes they also use Pharo in some of their projects) and together we recovered SeasideTesting from Davis Shaffer to be used for their TDD experience. you can check it out here: https://github.com/Afibre/SeasideTesting <https://github.com/Afibre/SeasideTesting> Whatâs SeasideTesting? A package to test Seaside components. Why we do not use Parasol? Because it is based on selenium and that makes the process slow. Where can I know more? - there is some documentation here (for VW, I think): http://www.shaffer-consulting.com/david/Seaside/TestingComponents/TestingCo… <http://www.shaffer-consulting.com/david/Seaside/TestingComponents/TestingCo…> - some slides here (on squeak): http://esug.org/data/ESUG2005/Wednesday/2005-ESUG-Shaffer.pdf <http://esug.org/data/ESUG2005/Wednesday/2005-ESUG-Shaffer.pdf> but all that is old. Best way is to just install and see the tests, as always, cheers! Esteban

Ah. Found it. Let me rephrase: why is the package cache for one image pointing at the package cache of another? Stephan

Quick method count metric: (BlElement methods reject: [ :aMethod | aMethod isDeprecated or: [ aMethod isExtension ] ]) size gives us *"224"* instance side methods. Or putting this into perspective: classes := Smalltalk allClasses collect: [ :aClass | aClass -> (aClass methods reject: [ :aMethod | aMethod isDeprecated or: [ aMethod isExtension ] ]) size ]. classes := (classes sorted: [ :a :b | a value > b value ]) collect: #yourself as: OrderPreservingDictionary. classes [image: Inline images 1] Cheers, Alex On 23 October 2017 at 09:49, Tudor Girba <tudor(a)tudorgirba.com> wrote: > Thanks for the feedback! > > Alex will reply in more details on Wednesday. > > In the meantime, some comments inline. > > > On Oct 23, 2017, at 4:15 AM, Sean P.

Hi Sean, Thanks for the feedback :) I will take a look and come up with an answer in a few days. If you have time to play more or if you found other issues, please feel free to list them here or open bug reports on Github ( https://github.com/pharo-graphics/Bloc/issues) Cheers, Alex On 23 October 2017 at 04:15, Sean P.

Esteban's ChangeLog week of 16 October 2017

by estebanlm＠gmail.com

Hello! This is my weekly ChangeLog, from 16 October 2017 to 22 October 2017. You can see it in a better format by going here: http://log.smallworks.eu/web/search?from=16/10/2017&to=22/10/2017 ChangeLog ========= 17 October 2017: ---------------- * I spent an stupid amount of time creating *platinum* account on [consortium site](http://consortium.pharo.org). :( * I spent a couple of days doing a new bridge for Objective-C (which allow cool stuff on macs, but not only). While this is not "direct-Pharo", I think the new "headless VMs" that will be a thing in the near future will allow more "native-oriented" development and interacting with the underlying platform is needed to make the echosystem boom in that area. There are still some caveats, but is already usable :) New bridge can be found [here](https://github.com/estebanlm/objcbridge). cheers! Esteban

Re: [Pharo-dev] Bloc status

Hi Sean, Bloc can be used for constructing element-based scenes. There is no built-in model for widgets yet. We use it in the new generation of the Glamorous Toolkit, and right now we have three such "real life scenariosâ that you can play with: - Transcript - Documenter - Mondrian You can find more details here: https://github.com/feenkcom/gtoolkit Cheers, Doru > On Oct 23, 2017, at 4:27 AM, Sean P.

Re: [Pharo-dev] Bloc status

by Dimitris Chloupis

I agree with Markus on that one , I am really a ârelease first update laterâ kind of guy. Which of course means also that I am against the idea of having only 1 release per year for Pharo. The why has been explained in myriads of online blog posts because I am far from the only one to believe in this. This why I never stuck with the stable release , I never saw any use for me or anyone else. Quite the contrary I think it hurts the development process by delaying bug reports.

Re: [Pharo-dev] XPath chapter...

by HernÃ¡n Morales Durand

I don't know for Pharo development, but I used XPath in Pharo for getting a textual description of gene ontology terms, for example: #('GO:0005623' 'GO:0017071' 'GO:0030680') do: [ : goTerm | | xPath xmlDoc quickGO | quickGO := 'http://www.ebi.ac.uk/QuickGO-Old/GTerm?id={1}&format=oboxml' format: { goTerm }. xmlDoc := (XMLDOMParser on: (ZnEasy get: quickGO) contents) parseDocument. xPath := XPath for: 'normalize-space(/obo/term/name/text())' in: xmlDoc. Transcript show: goTerm; tab; show: xPath; cr ]. Here you've got similar code in Perl and Java so you can compare: https://www.ebi.ac.uk/QuickGO-Old/clients/download-term.pl https://www.ebi.ac.uk/QuickGO-Old/clients/DownloadTerm.java Best regards, HernÃ¡n 2017-10-21 14:04 GMT-03:00 J.F.
