[Pharo-project] Issue 3794 in pharo: FinderUI gets out of sync when more than one Finder open
by pharo＠googlecode.com March 9, 2011

March 9, 2011

Status: New Owner: ---- New issue 3794 by DougEdmu...(a)gmail.com: FinderUI gets out of sync when more than one Finder open http://code.google.com/p/pharo/issues/detail?id=3794 Finder v.34 If a Finder window is open, it adds new typed-in entries to the top of the drop-down list. If a second Finder window is opened, the new entries are added to the top of the list. If you go back to the first Finder window, it will still show the entries as used by the first Finder window, but the index is now out of sync. If you select from the drop-down list from the first Finder window, Finder will look for the wrong item (presumably whatever is indexed at that position in the list). I think the problem has to do with using a class variable (SearchedTextList) for the drop down list.

[Pharo-project] Cloud IDE
by Geert Claes March 8, 2011

March 8, 2011

I just read that VMWare (Gemstone's parent) has just acquired Wavemaker (a company that I have been following since they were called ActiveGrid) who make a cloud IDE based on java/springsource (another VMWare acquisition). I actually thought that Gemstone was in a great position to create a cloud IDE/PaaS ... Smalltalk based of course :) http://www.keeneview.com/2011/03/wavemaker-springs-to-vmware.html -- View this message in context: http://forum.world.st/Cloud-IDE-tp3341921p3341921.html Sent from the Pharo Smalltalk mailing list archive at Nabble.com.

Comment #3 on issue 2792 by sebastia...(a)gmail.com: Process>>isTerminated raises an error time to time http://code.google.com/p/pharo/issues/detail?id=2792 I see a bug here too. I simply can't open the process viewer unless I use this pathed version of #isTerminated isTerminated self isActiveProcess ifTrue: [^ false]. ^suspendedContext isNil or: ["If the suspendedContext is the bottomContext it is the block in Process>>newProcess. If so, and the pc is greater than the startpc, the bock has alrteady sent and returned from value and there is nothing more to do." (suspendedContext isBottomContext and:[ suspendedContext pc isNil]) or:[ (suspendedContext isBottomContext and:[ suspendedContext pc > suspendedContext startpc])]]

[Pharo-project] PharoOneClick .lnk file
by Geert Claes March 8, 2011

March 8, 2011

I noticed that the .lnk file in the PharoOneClick downloaded from the ci.pharo-project.org does not work and - correct me if I am wrong - this is most because Windows shortcut files (.lnk) do not allow relative paths (http://stackoverflow.com/questions/3418541/how-do-i-create-a-shortcut-lnk-w…) So should the readme.txt file instruct Windows user to navigate to /Contents/Windows and start Squeak.exe ... and this should probably be Pharo.exe with a nice Pharo icon :) or create some sort of starter .exe app or .bat file? -- View this message in context: http://forum.world.st/PharoOneClick-lnk-file-tp3341518p3341518.html Sent from the Pharo Smalltalk mailing list archive at Nabble.com.

[Pharo-project] changing the bytecodes print
by Mariano Martinez Peck March 8, 2011

March 8, 2011

Hi folks. Did you see that when you see the bytecodes of a method you see something like: 49 <70> self 50 <21> pushConstant: 'SQ_HOST32' 51 <8F 00 00 02> closureNumCopied: 0 numArgs: 0 bytes 55 to 56 55 <71> pushConstant: true 56 <7D> blockReturn ....... The bytecode number here is printed in <hex> . However, in Interpreter and its #initializeBytecodeTable they use base 10. So, each time I read a bytecode, and I want to know which is the method associated with that, I need to convert it. So, I wonder if it makes sense to change the print, so that it prints in decimal. What do you think? To change that, it seems to be in InstructionPrinter >> #print but I cannot make it work yet :( cheers Mariano

[Pharo-project] Hardware cursor vs Software Cursor
by Fernando Olivero March 8, 2011

March 8, 2011

I believe that the senders or Cursor xxx showWhile: .. are using the wrong level of abstraction, by directly referring to the Cursor class reference and more important, that all visual related cues must go thru UIManager . If we take this approach further, we see there's 1) no need to have a special Cursor class. 2) We can remove the Hardware cursors and the software cursor distinction, so any Form can be used as a "cursor" image. Leading to an understandable implementation of the drawing behind HandMorph ( if not convinced try out " Cursor wait show" , and see that nothing happens) Solution: *Refactor HandMorph, removing the distinction between hardware and software cursor. *Make the Cursor senders, to use the proper level of abstraction ( not directly using the hardware cursor, such as Cursor wait showWhile:[..]) *Remove Cursor. I will work on this, and once create an issue once working. Saludos, Fernando

Re: [Pharo-project] Pharo on top of Flash plugin

(Mono is using it already). This means, it would be possible to port Cog to NaCl *and* have all the speed... Getting the stack interpreter to run should be even simpler (recompile.. plus implementing I/O via the NaCl APIs , of course). http://blog.chromium.org/2011/02/native-client-getting-ready-for-takeoff.ht… > - Alchemy (a research project at Adobe) compiles C into the bytecode > language interpreted by Flash. > ... > > Will let you know how it goes. Very interesting direction, too! The most challenging question is if it's possible to somehow "JIT" code... and how fast that then can be.
