[Pharo-project] How to use alien and/or FFI in OS X or iOS
by Gerold Pummer Nov. 1, 2012

Nov. 1, 2012

Hello! I want to use the native UI of iOS for my apps(*) and came across Alien and FFI. I did a ConfigurationOfAlien loadMacOSX to see the samples and each of this samples reveals a MessageNotUnderstood exception for Alien>>lookup if they are called. No errors on loading the packages into the image. ObjCRuntimeRef>alienMethodNamed: is calling Alien>>lookup: This method was moved from Alien to AlienLibrary with Alien-Core-sd.17. A closer look into the source (in Alien or AlienLibrary) shows that the given libraryname is completly ignored and only IAB32 is used. The first use of Alien>>lookup is found in ObjCRuntimeRef>initialize. Completely lost at the moment, because I'm sure the samples have worked (someday), but the changes in Alien (moved lookup and so on) are from 2009. Can you give me some hints what I did wrong, or what I should do to give better information to you? Is Alien/FFI the right path or should I use an other package (which one)? What I did: OS X 10.8.2 with the CogVM app for Pharo 1.4 and the summer from the pharo-project site. Gofer it squeaksource: 'MetacelloRepository' ; package: 'ConfigurationOfFFI' ; load. (ConfigurationOfFFI project version: '1.5') load. Gofer it squeaksource: 'MetacelloRepository' ; package: 'ConfigurationOfAlien' ; load. ConfigurationOfAlien loadMacOSX. I tried also 'ConfigurationOfOldAlien' because this version has the Alien>>lookup, but then I have no ObjCRuntimeRef/Samples. Many thanks in advance! Gerold (*) I have managed to compile an iOS VM under OS X 10.8.2 with XCode 4.5.1 with iOS SDK 6.0. Pharo 1.4 StackVM is running with the cleanForProduction Summer image on iPhone 4s and iPad2.

Hi, you can get inspiration from http://clamato.net/, a similar approach using petit parser to translate to javascript.

[Pharo-project] Smalltalk to Python and back
by dimitris chloupis Nov. 1, 2012

Nov. 1, 2012

Probably I have mentioned this several times but I am working on a project for visual programming targeting 3d app blender. I am using currently pharo though I am still interested in squeak too and I have decided that in order to communicate with blender python to use a socket bridge. My project is named "Ephestos". Now what was wondering is the following, how difficult it would be to parse smalltalk to python. Ephestos is of course smalltalk , and blender uses python for its addon system. It would be great if extensions made in Ephestos could converted to python addons. I am already planning to map smalltalk methods to Blender python api call, but I was wondering how easy it would be to parse that code to python. So far I am aware of OMeta and Petit Parser libraries. What are your suggestions ?

[Pharo-project] Problem with Date comparing summer time CEST
by Sabine KnÃ¶fel Oct. 31, 2012

Oct. 31, 2012

I have an attribute "date" in a domain object. Last week, I created some objects with this attribute. Today I created objects again with the same date value in this attribute. When comparing the dates (=), the result is false. Reason is, that in germany, we had a switch from Central European Summer Time (CEST) (Sommerzeit) to Daylight Saving Time (DST) this weekend. Date has an attribute "start" which has an instance of DateAndTime. This DateAndTime object has another value depending on the CEST/DST 2012-10-02T00:00:00+*01:00* (DST) 2012-10-02T00:00:00+*02:00* (CEST) When I create two Dates with same date, I expect that = evaluates to true, independent from the CEST/DST. But Date (Timespan) uses /= comparand ^ self class = comparand class and: [ *self start = comparand start * and: [ self duration = comparand duration ]]/ What do you recommend? Create my own compare method? Did I miss something? -- View this message in context: http://forum.world.st/Problem-with-Date-comparing-summer-time-CEST-tp465335… Sent from the Pharo Smalltalk mailing list archive at Nabble.com.

[Pharo-project] [OT] RTalk
by Torsten Bergmann Oct. 30, 2012

Oct. 30, 2012

Hi dimitris, if I remember correctly the idea from Mark Roos was to open source the environment/code once the company dependent parts are removed. AFAIK with an MIT license. For sure one can expect the bytecodeset and environment to be completely different from what we know from Squeak/Pharo. Some infos can be found on the web, see pointers below - but no code so far. Time will tell if it's ideas may be used to have later a Pharo dialect running on JVM as well (depending on community adoption, time, resources and technical possibility). It's not the first project to run Smalltalk on JVM. Its very silent around similar attempts like the last project "Redline" from James Ladd. At least it is active (last commit for Redline was 3 days ago). Bye T.
