Status of Pharo VM for FreeBSD
by Andreas Wacknitz April 6, 2015

April 6, 2015

Hi all, I have a question regarding the status of the PharoVM for UNIX operating systems, especially FreeBSD. As far as I have seen in the actual sources there is some support for FreeBSD available but for me itâs not clear whether itâs only partial or complete. For me it looks more partial (eg. there are no build instructions for FreeBSD and the default offers are only Mac, Linux and Windows), I havenât tried to build it yet but I am thinking about to do that and want to get an idea about the efforts. I have successfully build a PharoVM for openindiana (an OpenSolaris derivate). It runs both Pharo and Squeak images (at least partially, see below). I bootstrapped this on my Mac and used what was already available low level. Alas it has two problems until now: 1. Sound is not working properly (just a single click when doing some sound output and then silence). 2. NativeBoost is not working (atm it is based on the Linux version of NativeBoost). As my time is very limited (doing everything in my spare time) I would like to get NativeBoost working on openindiana first, and then trying to build an actual PharoVM for FreeBSD. Therefore the question regarding the status of PharoVM for FreeBSD. Of course any hints where to start with the NativeBoost problem would be highly appreciated :) Regards Andreas

Binding semantics of SystemDictionary
by Max Leske April 4, 2015

April 4, 2015

Hi Tommaso and I, while hacking on Fuel, today discovered that globals in Pharo can have very weird bindings (I guess some of you already know that). For example: class := Class new setName: 4; yourself. Smalltalk at: class name put: class. So we now have a class with name 4 (which is a SmallInteger): self assert: (Smalltalk at: 4) == class. There are basically two different issues: 1. SystemDictionary will store any kind of association, not only symbols / strings 2. SystemDictionary is an IdentityDictionary and as such two equivalent but not identical keys will not resolve to the same object: class := Class new setName: (String streamContents: [ :s | s nextPutAll: 'someName']); yourself. Smalltalk at: class name put: class. Smalltalk at: (String streamContents: [ :s | s nextPutAll: 'someNameâ]) ifAbsent: [ false ]. âââ> falseâ In Fuel we simply assume that any key to a global is either a ByteString or ByteSymbol. If thatâs not the case bad things happen. It would help us a lot if we could clear up the semantics of bindings in SystemDictionary: 1. Are bindings with keys that are not ByteString or ByteSymbol valid? 2. Should we keep allowing ByteString as keys to globals (ByteSymbol guarantees identity)? 3. If we allow ByteString, do we also allow WideString? 4. Would âtype checksâ on SystemDictionary incur a big performance penalty? Any suggestions are welcome. Cheers, Max

Enhancing the AST API
by stepharo April 1, 2015

April 1, 2015

Hi in Pharo 50 I would like to improve the AST API. often we do not know if an instance variable holds a position or a node and this should be clear. For example I propose to have leftPosition instead of left. Does anybody has a better suggestion? This is really annoying to have to look at the users of an instance variable to understand its role.

in Pharo4.0,Latest update: #40581: push down -> DNU
by stepharo April 1, 2015

April 1, 2015

Hi When I select an instance method and use push down in a subclass without obvious conflicts. I get two DNUs. realClass ^baseClass realClass theMetaClass dnu: theMetaClass while baseClass is a class realClass -> nil the environement does not contain the class. Now I did a class rename before and I wonder if it is not the one that is broken :( Stef

Moose Issue 1118: GT Inspector: Double Click Doesn't Always Select Text Properly
by Sean P. DeNigris March 31, 2015

March 31, 2015

https://code.google.com/p/moose-technology/issues/detail?id=1118 It took me a while to figure out that GT has a feature I've wanted for a long time: when you activate a workspace by clicking, the selection is preserved. Very cool! One thing though, where it also took me a while to figure out what was going on... 1. Type in the playground: 'aString'. 'anotherString'. 2. "Go" to bring up a second pane - doesn't matter which 3. Click in the second pane to put the keyboard focus there 4. Double click on one of the lines in pane #1 It is selected - great! 5. Repeat #3 6. Double click on the unselected line The selection will be cleared, but the other line will not be selected. NB: an interesting thing is that if you do the above exercise with a text editor outside the same GT window, like another GT Inspector, steps 5 and 6 work correctly just like the previous. ----- Cheers, Sean -- View this message in context: http://forum.world.st/Moose-Issue-1118-GT-Inspector-Double-Click-Doesn-t-Al… Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.
