[Pharo-project] new Cog VMs are available

by Eliot Miranda

Hi All, the VMs are available at http://www.mirandabanda.org/files/Cog/VM/VM.r2508. CogVM source as per VMMaker.oscog-eem.137/r2508. Fix primitiveContextAt[Put] for non-contexts (ContextPart subclasses other than MethodContext including BlockContext). stObjectAt[Put] could fail so args should be popped only on success. Fixes failures in ClosureCompilerTest>testSourceRangeAccessForBlueBookInjectInto as of VMMaker.oscog-eem.118. Add convenient shortPrintFrame:AndNCallers: for debugging. Make the unix launch script include /lib & /usr/lib in LD_LIBRARY_PATH if LD_LIBRARY_PATH is unset. Modify the invocations of ex in the editing scripts to not read ~/.exrc, and hence not be confused by e.g. set ignorecase. Fix error codes for at: and at:put: primitive so that for non-indexable objects they fail with #'bad receiver', not #'bad index'. Filter-out attempts to create MNU pics with new selectors. Fixes Stephane Rollandin's crash of 21/10/2011: [((Compiler new evaluate: ('Beuh' ifNuk: [yo])) on: Error do: [:ex | ex description]) printString] fork -- best, Eliot

[Pharo-project] caputriing redButtonPressed and controlKeyPressed

by Hilaire Fernandes

In the code bellow, redButtonPressed and shiftPressed are detected correctly. However if I replace the #shiftPressed message by #controlKeyPressed message the redButtonPressed and Control key can not be detected *at the same time* Indeed, if I remove the redButtonPressed test, ControlKeyPressed is detected. All in all, it looks like redButtonPressed and ControlKeyPressed cannot be captured at the same time. I am under Linux VM. Is it an known problem? Hilaire mouseMove: evt (evt redButtonPressed and: [evt shiftPressed]) ifTrue: [...]. -- Education 0.2 -- http://blog.ofset.org/hilaire

[Pharo-project] Cluster analysis of Pharo source available?

by Guido Stepken

I like such things, like visualizing class dependencies with girvan newman algorithm: http://igraph.sourceforge.net/screenshots2.html or here: http://www.little-idiot.de/teambuilding/apache-structure.pdf Should be nice to see, how Pharo has changed over time. Are there such "reflective tools" available in Pharo? (Should be pretty easy to handover a list of Pharo class dependencies to igraph ...) Tnx, Guido Stepken

Re: [Pharo-project] GlorpDBX PostgreSQL Patch

by Alan Knight

My inclination would be to think that this is something that the database driver ought to be handling rather than having it in Glorp at all. But, given that it's in there, I suppose it's not unreasonable. > ------------------------------------------------------------------------ > > Mariano Martinez Peck <mailto:marianopeck@gmail.com> > 9 November, 2011 8:59 AM > > > Thanks Sven.

Re: [Pharo-project] Icon for commented/uncommented classes

by Milan Mimica

In Pharo 1.4, class comments are always visible when looking at the class definition. So it does expose the comment more, asking you to write one. 2011/11/9 Janko MivÅ¡ek <janko.mivsek(a)eranova.si> > Hi guys, > > It would be very nice to visualy indicate in browser when some class has > comment, or even better, when not.

[Pharo-project] SmalltalkHub news

by Nicolas Petton

Hi, We've been very quiet about SmalltalkHub's development since ESUG 2011. It's not that we didn't work on it, but there was no significant new feature to show. Part of the work was to make SmalltalkHub run smoothly on GemStone/S as well as under Squeak/Pharo, and allow pluggable persistency strategies instead of the hard-coded SandStoneDB persistency. We also took into account all the feedback we got and implemented several of the asked features and fixed reported issues: - RSS feeds for project activity and commits - markdown fixes - issue tracker improvements - better looking and more useful timeline events - loading indicators when necessary - project cloning fixes We are currently preparing a public demo of SmalltalkHub. It should be online after this weekend. This demo will be running on GemStone/S, will have many UI improvements and the usual bug fixes. Some features like project cloning and the scripting engine may not be available depending on the time we get. Cheers, Nicolas

Re: [Pharo-project] Website RSS feed broken?

by Max Leske

Yes, I saw that. We're still investigating. The empty entries shouldn't matter, although I agree that they are ugly. I haven't forgotten your and I'll keep you posted.

[Pharo-project] Icon for commented/uncommented classes

by Janko MivÅ¡ek

Hi guys, It would be very nice to visualy indicate in browser when some class has comment, or even better, when not. This is good for many reasons: - you know where to read comments and where is not worth trying - authors are encouraged to write those comments, to increase reputation avoid having too much that ! icons near not commented classes Also the ? button in browser should be red if there is no comment. This can be disabled in settings but by default it should be enabled. Best regards Janko -- Janko MivÅ¡ek Aida/Web Smalltalk Web Application Server http://www.aidaweb.si

Re: [Pharo-project] Website RSS feed broken?

by Stefan Marr

Hi: The two offending news items are 'Pharo News #1' and 'Pharo News #3: Pharo 1.0 released'. Both changed their guid again. So, they are considered new. Ah and by the way, there are a couple of empty items in RSS feed, which change their links with every updated. The author tag says: <author>alienhard(a)netstyle.ch (board)</author> So, maybe it is something specific to the pharo news entries, since the TextLint entry did not pop up again?
