Do we want this for Pharo 1.2 and futures?

by Mariano Martinez Peck

In Pharo 1.0 and 1.1 I used to include certain files in addition to the .image and .changes. These files were: changelog.txt, installScript.st and packages.txt So...what do you think? are they (still) useful ? if true, then we should add it to hudson. If not, we just ignore it. Thanks Mariano

Thanks mariano. It was cool and I like the hands-on because we are not just taught but we participate and learn. On Mar 11, 2011, at 10:44 PM, Mariano Martinez Peck wrote: > Hi all.

Re: [Pharo-users] Problem with Sounds

by Matthew Fotzler

Is there another VM I should be using, or how can I fix this problem? (I'm using the Squeak 4.2.5beta1U VM from the pharo site) Thanks, Matthew On Mon, Mar 7, 2011 at 10:04 AM, StÃ©phane Ducasse <stephane.ducasse(a)inria.fr> wrote: > Thanks matthew > > I know that my VM does not have all the sound primitives. > > Stef > > > On Mar 7, 2011, at 4:46 PM, Matthew Fotzler wrote: > >> Hi Stef, >> >> I tried with the 1.2 release candidate, and I can't get the sound to >> play at all.

SharedPool classVars

by Paul DeBruicker

Do SharedPool classVars need to be wrapped in parenthesis? I'm messing around with porting Chronos to Pharo and Gemstone. It currently uses a number of shared pool dictionaries. I'm converting those to subclasses of SharedPool. In the package there is a large number of references to the classVars of the SharedPool. Almost everytime one is accessed I get a DNU or the value comes back as 'nil'. But if I wrap that particular reference in parenthesis the code works fine. So this doesn't work: addHours: hours ^self addSeconds: hours * SecondsPerDay But this does work: addHours: hours ^self addSeconds: hours * (SecondsPerDay) I do not want to track down every reference to every class var and wrap it in parenthesis. Is there something else I can try? Or is there a refactoring rewrite rule I can run to find all references to a SharedPool class var and wrap it in parens? Thanks Paul

When a Pharocast goes too fast for me

by DougEdmunds

1) I'm using a Windows box. Can't help with Mac or Linux. I downloaded the free GOMPlayer. http://www.gomlab.com/eng/ If I want a slower playing Pharocast, I download it, then view it in the GOMPlayer. The control panel has a nice set of buttons for faster/slower playback. -- View this message in context: http://forum.world.st/When-a-Pharocast-goes-too-fast-for-me-tp3342557p33425… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.
