how to import a grammar file into Pharo
by Jen D'Souza Feb. 23, 2016

Feb. 23, 2016

Greetings all, I'd really appreciate if someone could guide me through importing PetitIsland.st (http://mucca.inf.usi.ch/source-code.html) into Pharo and parsing a text file containing a mix of code and natural language with the resulting parser. Thanks in advance! Jen

#ifCurtailed: multi-thread semantics
by Ben Coman Feb. 22, 2016

Feb. 22, 2016

Just a curiousity. I learnt something new today... #ifCurtailed blocks are processed in the outer most thread. Transcript clear; crShow: Processor activeProcess; show:' - outside'. p1 := [ [ Transcript crShow: Processor activeProcess; show: ' - inside'. 1 second wait. ] ifCurtailed: [ Transcript crShow: Processor activeProcess; show: ' - curtailed' . ] ] newProcess priority: 41. p1 resume. p1 terminate. ==> a Process(304957184) in nil - outside a Process(680396800) in nil - inside a Process(304957184) in nil - curtailed This makes some sense since (I guess) the inside thread is terminated before the curtailed block executes. However another curiousity... Transcript clear; crShow: Processor activeProcess; show:' - outside'. p1 := [ Transcript crShow: Processor activeProcess; show: ' - middle'. p2 := [ [ Transcript crShow: Processor activeProcess; show: ' - inside'. 1 second wait. ] ifCurtailed: [ Transcript crShow: Processor activeProcess; show: ' - curtailed' . 2 seconds wait ] ] fork. 3 second wait. ] newProcess priority: 41. p1 resume. p2 terminate. ==> a Process(304957184) in nil - outside a Process(146580480) in nil - middle a Process(417340928) in nil - inside a Process(304957184) in nil - curtailed ...why does the curtailed block execute in outside thread rather than the middle thread which still exists? Also interesting is that if the curtailed code contains a wait, it blocks the whole UI. cheers -ben btw, I added... Process>>printOn: aStream super printOn: aStream. aStream nextPutAll: '(' , self hash printString , ') in '. suspendedContext printOn: aStream

embedding images inside Playground
by Peter UhnÃ¡k Feb. 21, 2016

Feb. 21, 2016

Hi, is it possible to somehow embed images (Form) inside Playground? The use case is a kind of in-image help or guide where one could also execute code, but there would be also example images. Or maybe have a container Morph that would contain Playground? Is that possible? Thanks, Peter

Using GTSpotter how do I find an implementor of #accept ?
by Paul DeBruicker Feb. 20, 2016

Feb. 20, 2016

when I hit shift+enter and type 'accept' I get things that are not #accept, e.g. #accept: and AbstractAcceptor. If I add a space after accept it doesn't help. What do I not understand? Thanks Paul

libUSB binding Pharo
by FranÃ§ois Stephany Feb. 20, 2016

Feb. 20, 2016

Hi, Is there a libusb[1] binding for Pharo 4/5? After a quick google search, I've seen that Udo Schneider has started one last year. Any idea on its status? If not, would it be a nice summer job for a student (my company can pay for it...)? Cheers, Francois [1]: http://libusb.org/

For my CV, I need to know who is using the stuff I'm doing. If you use Pillar, could you please tell me in which context (e.g., which company, open-source project) and what you use it for (e.g., what kind of document)?
