Set Rounding mode for IEEE floating point operations
by Steffen MÃ¤rcker May 29, 2018

May 29, 2018

Hi, is there any way to set the rounding mode for IEEE floating point operations? Maybe something like > Double roundToMinusInfWhile: [... code goes here ...]Double > roundToZeroWhile: [... more code here ...] If not, is it possible to add this behavior, e.g., via a custom primitive? Best, Steffen

Hi, I'm getting this error while trying to prototype some interface with Spec on Moose 6.0: MessageNotUnderstood: ToolDockingBarMorph>>popUpOwner it happens anytime that I'm using displaying a MenuModel and I go to the menu items. I imagine that the menu item is complaining about a lacking pop up message. How can I solve this? Thanks, Offray

#ast vs. #parseTree
by Sean P. DeNigris May 9, 2018

May 9, 2018

Why does CompiledMethod understand both? They are in the same protocol, produce the same kindOf result, and neither has a method comment! :/ (Pharo 4.0) ----- Cheers, Sean -- View this message in context: http://forum.world.st/ast-vs-parseTree-tp4893074.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

"News" section of the website down
by Mathieu Dubois April 9, 2018

April 9, 2018

Hello, I don't know how to report that but for several weeks (maybe months), I can't reach the "News" section of the website (I have tried from several locations with different ISP). I usually get a timeout error (error 524 from Cloudflare) that comes from pharo.org. Mathieu

How would I make my own images available via Launcher. Where can I read about this or can you point me to a hook? Thanks! ----- Cheers, Sean -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

unsolicited package-cache use
by Hilaire April 3, 2018

April 3, 2018

I am using tonel format to install from and save to a local repository. How to prevent Monticello/Configuration/Metacello to save packages to the image package-cache dir? Even when installing from a configuration with repo on tonel file format, packages get created in the image package-cache directory. I have read there and there, Pharo gets confused and uses wrongly the package-cache versions and not the local repo. -- Dr. Geo http://drgeo.eu

Keeping packages up to date
by Andrei Stebakov April 1, 2018

April 1, 2018

I wonder if there is a generic solution to keeping certain Pharo project in sync with development tree. For example when I want to get latest Roassal I execute Gofer it smalltalkhubUser: 'ObjectProfile' project: 'Roassal2'; package: 'Roassal2'; package: 'Roassal2GT'; package: 'Trachel'; load. Also I wouldn't know this unless the maintainers (thanks Alexandre!) of the project told me what script to execute to get the latest version. If I went to Project Catalog I can only get the stable version and if I go and find Roassal2 it won't give me information how to get its latest version. How would I get info about how to update, say Roassal given the script above from some Roassal project public page? Talking about Roassal, if I go to http://smalltalkhub.com/#!/~ObjectProfile/Roassal2/ page, it offers the following script: Gofer it smalltalkhubUser: 'ObjectProfile' project: 'Roassal2'; configurationOf: 'Roassal2'; loadDevelopment Which is probably not exactly equal to the script above (or is it?). So, is there a generic way to get a latest version of some XYZ package? What do I need to learn to be able to get that information about any Pharo project (other than asking the community)? Something similar to "git pull" when you know the repository.

Regarding Raven: DOCap System
by henry April 1, 2018

April 1, 2018

@m_m#3045 for concurrency without shared state, running on a single green thread (smalltalkâs Process) with support for remote async sends to other images, there is my Raven [1], using Cryptography [2], ParrotTalk [3] and STON. This is an implementation of erightâs [4] ELib. I am working on implementing STON for Java, inside the ASN1 project [5] as I already have ParrotTalk in Java [6], binary interoperate with Squeak/Pharo, and my Raven work in progress in Java [7]. This model allows message send redirection to a promise or farRef (or nearRef) as an asynchronous send returning a promise, which supports whenResolved/whenBroken handlers to be registered per PromiseERef. Iâll be happy to answer any questions you may be having about Raven. Raven is an implementation of an Actor model called Communicating Event Loops, in some literature [8] [9]. I hope this helps!
