New CogVMs available...
by Eliot Miranda April 2, 2015

April 2, 2015

... at http://www.mirandabanda.org/files/Cog/VM/VM.r3306. CogVM binaries as per VMMaker.oscog-eem.1155/r3306 Retract the decision to type the results of the bitwise operators as unsigned; it broke at least the BitBlt plugin. Integrate primitiveIsBigEnder & Nicolas' fix for safer primitiveAdoptInstance & primitiveScanCharacters Mark relevant feature test methods in CogAbstractInstruction as <inline: true>. Spur: Make sure that all stacked values are followed in CoInterpreter>> makeBaseFrameFor: for stale self refs in super sends. Make sure the stack is scanned after a pin operation that involves forwarding. Make sure that the unforwarding stack scan post-become (or post-pin) scans all of the stack contents in the CoInterpreter, since super sends have no read barrier. Mark copyToOldSpace:bytes:format: as not to be inlined so as to avoid impacting copyAndForward's icache density. Newspeak: Add Ryan's new self-send bytecodes. Use NSSendCache for IRC representation. -- best, Eliot

Re: [Pharo-dev] Bloc Roadmap

> yes, we know, we are preparing a documentation. Great! Is the WIP publicly available (e.g. in one of our Pillar/GitHub repos)? Btw. the class comments are reeeally great! I'm only talking about documenting design rationale. > Weâve implemented a lot of examples. please have a look. Thanks - I have and they are also great. But AFAICT it's impossible to tell from the examples /why/ e.g. we went from Morphs owning their step actions to block-based steps registered with a scheduler that is universal to all worlds. I have a doubt about that because one use case I've had in Morphic is to speed up time in a world to see what happens e.g. in 10 minutes from now, but #schedule hard-codes the reference to the BlUniverse singleton. ----- Cheers, Sean -- View this message in context: http://forum.world.st/Bloc-Roadmap-tp4816171p4816769.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

(a = b) ifTrue: []
by Anne Etien April 2, 2015

April 2, 2015

Hi, I wanted to write a method that: - if (a = b) checks other conditions that are specified in the ifTrue block and return this (boolean) value - returns false if (a!=b) So I wrote: myMethod ^ (a=b) ifTrue: [ aBlockCheckingConditions]. However, when (a!=b) the method returns nil (since false ifTrue: [] returns nil). So do you have an idea how I can do to express that or should I mandatorily wrote also an ifFalse:? The problem comes certainly because we donât know that the ifTrueBlock will return a boolean. If you have prettier ideas, I am interested in. Anne

PharoV30.sources in Pharo 4.0 download
by Dmitri Zagidulin April 2, 2015

April 2, 2015

I noticed that the Pharo 4.0 full distribution zip file off of Pharo.org/download contains PharoV30.sources (and not, say, PharoV40.sources). This is true for all 3 platforms: - http://files.pharo.org/platform/Pharo4.0-mac.zip - http://files.pharo.org/platform/Pharo4.0-win.zip - http://files.pharo.org/platform/Pharo4.0-linux.zip Is there a typo in a CI job somewhere?

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.

Got a strange font bug
by stepharo April 1, 2015

April 1, 2015

HI we were improving the selection of instance variables of the refactorings via nautilus when suddenly the font got broken. We got a problem with strikefont holding a number of something like that. Impossible to debug - it would be great to have a rescue path (may be via the EmergencyEvalutor) - the only thing that we could do was to kill the image and restart I suspect a problem with the FTPlugin.
