I do not get this. Relying on the baseline is not enough? Roassal is very simply packaged. Only 4 packages: Roassal, Trachel, Roassal2Spec, Roassal2GT. It is very unlikely that this list of package will grow (not until we have a Git integration at least). You can make your configuration directly point to these packages no?

Indeed, I am reverse engineering a database containing around 80 tables and lot of foreign keys and the result is not readable since the edge are orthogonal starting from the top or the bottom of the box corresponding to the column name.

Strange behavior of Pragma>>#allNamed:in:
by Julien Delplanque Feb. 24, 2016

Feb. 24, 2016

Hi, I experience a strange behavior with Pragma>>#allNamed:in: When I use Pragma allNamed: #myPragma in: MyClass It works as expected. But when instead of hard-coding "MyClass" I use "self class" in an method (instance side), Pragma allNamed: #myPragma in: self class returns an empty array. What can I do about it? Julien

curiousity, ensure unwind block priority inheritance
by Ben Coman Feb. 23, 2016

Feb. 23, 2016

Just thought I'd share something enlightening I learnt today, a curious surprise... When a process is terminated, the #ensure: unwind block effectively inherits the priority of the terminator process. Thus the following... log := OrderedCollection new. s := Semaphore new. p := [ [ log add: 1. s signal. log add: 4. ] ensure: [log add: 5] ] forkAt: 30. s wait. log add: 2. "p terminate." log add: 3. 100 milliSeconds wait. Transcript crShow: log. ...gives {1 2 3 4 5} as expected. However uncommenting the terminate statement produces {1 2 5 3}. Quite non-intuitive** to have the "5" code inside the priority 30 block execute before the "3" code of the priority 40 of the UI/Playground. **meaning it bit me for a few hours trying to understand some ProcessTests related to Case 17588. cheers -ben

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
