Google Code Shutdown
by Sean P. DeNigris Aug. 5, 2015

Aug. 5, 2015

In case anyone hasn't heard, Google Code will shut down entirely on January 25, 2016. I was following these Smalltalk projects there: magritte-metamodel moose-technology seaside marsonpharo nativeboost metacello squeaksource3 phratch - already on GitHub per Jannik The easiest action seems to be to export to GitHub, for which Google Code even provides a button! I just used it for one of my projects and it was pretty painless. - Sean Cross-posted to ESUG, pharo-dev, squeak-dev, seaside-dev, magritte, metacello ----- Cheers, Sean -- View this message in context: http://forum.world.st/Google-Code-Shutdown-tp4814760.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

cleanup rubric
by Nicolai Hess Aug. 5, 2015

Aug. 5, 2015

Maybe I am wrong, but it looks like there are many classes and code in rubric that are the same as in the old Text classes. Rub is used in GT and now in the Core image. Shouldn't we clean this up before it used everywhere? Some examples: All TextLink classes looks the same (TextClassLink <-> RubTextClassLink) MorphAnnouncement subclass: #RubMorphAnnouncement RubMorphAnnouncment adds nothing FindReplaceService <-> RubFindReplaceService They look very similar, I don't understand why so much code is just the same in both, why not extract that into a base class? (and the same for RubFindReplaceDialogWindow/ FindReplaceDialogWindow and some many too) RubEditingState / EditingState. What this makes it even worse, Rubs class comment doesn't indicate how they differ from the old other one. It is really difficult to understand, - which (Rub)classes were created just because the old TextApi has them, but aren't actually used in the current Rubric framework. - wich classes are used but could be replaced with the existing one (TextLink for example) - which classes had to be changed, and therefore only the Rub-classes can work with rubric. - which classes are similiar named like the old Text classes and share some code but may work totally different. (For example TextEditor vs. RubTextEditor there are some methods in both that aren't used anywhere, it looks like RubTextEditor is just - a copy from TextEditor, - changed where it was needed - unchanged otherwise Rubric really adds some great new things and if you look at where it is used, it is really a great step forward, but the code is in a bad state. This needs to be cleaned up.

NAtiveBoost error
by Alain Rastoul Aug. 1, 2015

Aug. 1, 2015

Hi, I have a problem with a nativeboost call, but I don't see what I do wrong. library function prototype is: int zmq_getsockopt (void *socket, int option_name, void *option_value, size_t *option_len); my calling method in pharo is: zmq_getsockopt: socket option_name: option_name option_value: option_value option_len: option_len <primitive: #primitiveNativeCall module: #NativeBoostPlugin error: errorCode> ^self nbCall: #(int zmq_getsockopt (void *socket, int option_name, void * option_value, size_t* option_len) ) when I call it with ... optionValue := (NBExternalArray ofType: 'int') externalNew: 1. optionLen := (NBExternalArray ofType: 'size_t' ) externalNew: 1. [ optionValue at: 1 put: 0 . optionLen at: 1 put: (NBExternalType sizeOf: 'int') . rc := self zmq_getsockopt: socket option_name: option_name option_value: optionValue option_len: optionLen . value := optionValue at: 1 . ] ensure: [ optionValue free. optionLen free ]. ... I allways get an exception: "error during FFI call : nil" After stepping in NBFFICallout generation, I found something strange, the code generation seems not to be called because lastError stays at nil ? handleFailureIn: aContext nativeCode: aBlock lastError := self getErrorFrom: aContext lastError: NativeBoost lastError. >>getErrorFrom: aContext lastError: errorCode ... checks pragmas etc >>getErrorFrom: aContext lastError: errorCode ... lastError := aContext tempAt: method numTemps. => lastError = nil ??? shouldn't be ErrNoNativeCodeInMethod ? "install native code and retry the send" lastError = ErrNoNativeCodeInMethod ifTrue: [ ^ self generateCode: aBlock andRetry: aContext ]. never gets called ... "ok, we're out of options, signal an error here" ^ self signalError: lastError Could it be because I use this image on windows and unix ? Or because I had an exception at prototype parsing the first time because I forgot a ; at the end of the prototype ? Is my prototype correct or is it the origin of the error ? Is there a way to reset the lastError (aContext tempAt: method numTemps) ? I will try to reset it in debugger but may be there is a cleaner way ? would it be ok to change the test in handleFailure to (lastError = ErrNoNativeCodeInMethod) or:[ lastError isNil ] ? (I can open a bug in this case ) Any idea or comment is welcome Thanks in advance Alain

Freezing Bloc UI
by Peter UhnÃ¡k July 31, 2015

July 31, 2015

Hi, when reloading FreeType (Settings > Use free type:) and then trying to change the font (Standard Fonts >> default) some inputs are not drawn and the UI freezes completely. Interestingly if I press alt+<dot> the UI doesn't respond, but the Image clearly does because there is output in the command line: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ âUser Interrupt [ delaySemaphore wait ] in Delay>>wait in Block: [ delaySemaphore wait ] BlockClosure>>ifCurtailed: Delay>>wait BlMainLoopManager>>interCyclePause: BlMainLoopManager>>doOneCycle [ self doOneCycle.

New methods for the String class
by Daniela Meneses July 31, 2015

July 31, 2015

Hi to all, As you may know I'm working on in some improvements for the String class. Until now I implemented some missing tests. Right now I'm looking forward to add new methods that could be useful based on Ruby API ( http://www.ruby-doc.org/core-2.1.0/String.html) These are a few of the methods that I'm planning to implement: - chomp(separator=$/) -> new_str - chop() -> new_str - ljust(integer, padstr='') ->new_str - next -> new_str - partition(sep) -> [head, sep, tail] Could you help to find out if these methods are already available for the String class? If you have any idea of new methods for the string class, will be really welcome. -- Cheers , Daniela Meneses
