Pharo in a read-only environment survey
by JÃ©rÃ©mie Regnault June 20, 2017

June 20, 2017

Hi, I'm working on Pharo deployment in a read-only environment, and I want to know what behavior you want Pharo to adopt. If you could take 5-10 minutes to fill my survey, it would be nice : https://goo.gl/forms/8S7w4079NDfBrsVu1 Thank you, -- JÃ©rÃ©mie Regnault

aSortedCollection collect: returns OrderedCollection instead of original sorted
by Denis Kudriashov June 19, 2017

June 19, 2017

Hi. I just found that #() asSortedCollection select: [ ] => SortedCollection #() asSortedCollection collect: [ ] => OrderedCollection It feels like a bug to me. But maybe there is a reason why sorted collection collects items as OrderedCollection instead of original kind of sort? My usercase was copy of object with sorted collection inside. For this I just manually collect copy of each item. But at the end my copy became broken because of sort was important for domain logic. Best regards, Denis

Extra shortcut modifier opposite to #meta
by Denis Kudriashov June 19, 2017

June 19, 2017

Hi. There was long discussion about some Spotter shortcut issue http://forum.world.st/GT-Spotter-dive-in-shortcut-td4899612.html. Problem: for back/forward navigation Spotter uses #meta modifier for shortcut which overrides standard text navigation. Suggested solution: introduce kind of "alternative meta" to get opposite values for Mac and Windows relative to normal meta. It should get platform independent modifier which not overlaps with text navigation. I not found anything implemented. Let's do it in Pharo 7. What name should be used? I like #alternativeMeta Best regards, Denis

Hi, I am a GSoC student working on enhancing pharo command line interface. I was wondering if there is a procedure to make a pull request to the Github repo. It would be really helpful if someone can explain the right way of doing a Pull Request. Thanks in advance.

Why allChildrenMatching: does not match extension? allChildrenMatching: aPattern "Return all the files and folders recursively nested in the receiver and matching the pattern, aPattern" ^ self allChildren select: [ :each | aPattern match: each basename ] I would rename allChildrenMatching: aPattern into allChildrenNameMatching: aPattern

Why don't the Zero Conf examples show how to launch Pharo?
by Tim Mackinnon June 15, 2017

June 15, 2017

Hi - I was wondering why the command line section on the http://pharo.org/web/download <http://pharo.org/web/download> page, doesnât show you how to then launch the app you have just downloaded? Iâm not sure if there is a way to do it all on one line (I tried && ./pharo-ui Pharo.image - but this doesnât work). However I think the website example should at least have: # then run it ./pharo-ui Pharo.image Otherwise we make it harder for people to figure out what to do with the program weâve pointed them to?

Big Pharo 6 Image (32 bit) crashes while garbage collecting
by Cyrille Delaunay June 14, 2017

June 14, 2017

Hello, I am running a Pharo 6 32 bit image (Pharo 6.0 Latest update: #60499). I saved this image after loading big data in memory (image is 995 MB). After saving, the image became "unstable", and always crashed after doing some random actions. I tries to open the image and perform: Smalltalk garbageCollect. The image systematically crashes. I Join the dump files I have been able to collect. -- Cyrille Delaunay
