[ann] [objective-cl-announce] Objective-CL 0.2.2
by Matthias Benkard 23 Mar '08

23 Mar '08

Hi all, I have released Objective-CL 0.2.2. It's primarily a bug fix release. * Quick Summary No dependency on Darcs versions of CFFI. CMUCL can be used again. AMD64 compilation problems have been fixed. Moderate speed improvements for method invocation. * What's New? ** CFFI 0.9.2 Support Objective-CL has always included support code for different CFFI versions, but the support for anything older than a more or less recent Darcs checkout turned out be broken. This release fixes the brokenness, so release versions of CFFI should actually be supported now. ** CMUCL Compatibility As CMUCL does not support closures as funcallable-instance-functions, a workaround had to be implemented. This has been accomplished by compiling a new lambda expression every time a selector is initialised. This, of course, makes (COLLECT-SELECTORS) slower than on other implementations and probably wastes a certain amount of memory, but it works. ** Speed Improvements Method invocation speed has been improved a bit. See the development diary (file JOURNAL) for details. ** AMD64 Compatibility The Objective-C support code from PyObjC used to assume that ssize_t and int are equivalent. One search-and-replace procedure later, Objective-CL compiles on AMD64 GNUstep machines. This new support has not been extensively tested, so it may still be broken in some way or another. Furthermore, a similar procedure has not been applied to the Apple-specific pieces of the PyObjC support code yet Bug reports are welcome. Have fun! ~ Matthias _______________________________________________ objective-cl-announce mailing list objective-cl-announce(a)common-lisp.net http://common-lisp.net/cgi-bin/mailman/listinfo/objective-cl-announce

[ann] [movitz-announce] Macros in Movitz run-time, etc.
by Frode Vatvedt Fjeld 21 Mar '08

21 Mar '08

The following message is a courtesy copy of an article that has been posted to gmane.lisp.movitz.devel as well. I'd just like to mention that I've recently added macros to the movitz run-time (and eval). That is, macros in general should work as you expect at the REPL, and the "macro-function" and "macroexpand" functions should work according to spec. Notable macros that work are do, dotimes, dolist, and destructuring-bind. Notable not-working-yet macros are loop, defclass, and defmethod (i.e. macros that require extensive machinery beyond the syntax layer). The macro-expanders are compiled (at create-image time, like normal functions). This increases the time and output size of create-image somewhat, but the default kernel still clocks in well below the size of a floppy image (1.44 MB). Furthermmore, a number of special operators have been added/improved in the run-time eval. I expect eval to be reasonably complete soonish. Finally, the compiling of macros triggered a few compiler bugs that have now been weeded out (also increasing compiler speed). -- Frode Vatvedt Fjeld _______________________________________________ movitz-announce site list movitz-announce(a)common-lisp.net http://common-lisp.net/mailman/listinfo/movitz-announce

[ann] [cdr-announce] CDR 5 revised
by Pascal Costanza 08 Mar '08

08 Mar '08

The document "Sub-interval Numerical Types for Common Lisp" has been revised by its author Marco Antoniotti. It has also changed its name - the previous name was "Extra Numerical Types for Common Lisp". This document is still in its initial stage and will be finalized on April 9, 2008, unless withdrawn by the author beforehand. See http://cdr.eurolisp.org/document/5/ for more details.

[ann] [closer-announce] Article about COP in JOT
by Pascal Costanza 08 Mar '08

08 Mar '08

Hi everybody, There is a new article about Context-oriented Programming in the Journal of Object Technology, and it can be viewed and downloaded at http://www.jot.fm/issues/issue_2008_03/article4/ It discusses context-oriented extensions for Common Lisp, Smalltalk and Java, namely ContextL, ContextS and ContextJ. There is a new ContextL example presented in this article that we haven't discussed in any of the previous papers, so it should be an interesting read for ContextL users as well. As always, please feel free to send feedback and suggestions. Best, Pascal -- 1st European Lisp Symposium (ELS'08) http://prog.vub.ac.be/~pcostanza/els08/ Pascal Costanza, mailto:pc@p-cos.net, http://p-cos.net Vrije Universiteit Brussel, Programming Technology Lab Pleinlaan 2, B-1050 Brussel, Belgium _______________________________________________ closer-announce mailing list closer-announce(a)common-lisp.net http://common-lisp.net/cgi-bin/mailman/listinfo/closer-announce

[ann] [objective-cl-announce] Objective-CL 0.2.1
by Matthias Benkard 07 Mar '08

07 Mar '08

Hi all, I have released Objective-CL 0.2.1. This release adds convenience and robustness to the previous one. * Quick Summary Super calls are supported. Bugs have been fixed. You may omit DEFINE-OBJECTIVE-C-GENERIC-FUNCTION calls. * What's New? ** Super Calls Up to now, there was no way of doing the equivalent of a message send to `super' as in Objective-C. This has changed. Just as with CALL-NEXT-METHOD for standard methods, you may now either call (SUPER) as-is or with the arguments you wish to pass to it. See the SUPER function in the reference manual for details. ** Implicit Definition of Objective-C Generic Functions DEFINE-OBJECTIVE-C-METHOD now takes care of defining a suitable OBJECTIVE-C-GENERIC-FUNCTION for you if you don't do so yourself. ** Bug Fixes Lots of little bugs are gone as well. Among others, returning values from Objective-C methods now works much more reliably, and Lisp wrapper objects don't just vanish when the GC runs as long as the corresponding foreign instance is still referenced by Objective-C code. I'm still wondering what to do on garbage-collected Objective-C runtimes. Have fun! ~ Matthias _______________________________________________ objective-cl-announce mailing list objective-cl-announce(a)common-lisp.net http://common-lisp.net/cgi-bin/mailman/listinfo/objective-cl-announce

[ann] [objective-cl-announce] Objective-CL 0.2.0
by Matthias Benkard 05 Mar '08

05 Mar '08

Hi all, Objective-CL 0.2.0 has been released. This release is a major milestone on the way to 1.0.0. * Quick summary We can now define Objective-C classes and methods without writing a single line of Objective-C code. The API may not be stable and there might be crashes, but living dangerously is half the fun, right? ;) * What's new? ** Method call syntax #.(enable-method-syntax) We now support Clozure CL's new method call syntax via reader macros. That means you can write: (let ((lock (#/new (find-objc-class 'ns-lock)))) (#/lock lock) (print (#/stringWithCString:encoding: (find-objc-class 'ns-string) "Hi there!" 0)) (#/unlock lock)) In fact, as the reader macro does no more than offer an alternate syntax for symbols, you can do things like using it with APPLY as well: (apply #'#/stringWithUTF8String: (find-objc-class 'ns-string) (list "Hi again.")) ** Class definition You can now define classes. For example, the following will define a subclass of NSObject called MLKMyClass, including a native slot called FOOS and a foreign slot (that is, an Objective-C ivar) called FOO-COUNT (fooCount on the Objective-C side): (define-objective-c-class ns::mlk-my-class (ns::ns-object) ((foos :initargs :foos) (foo-count :foreign-type :int))) Simple CFFI type specifiers are recognised by :FOREIGN-TYPE, but please note that complex types such as struct and union types are not yet supported. ** Method definition You can now define Objective-C methods from Lisp for your own classes. The following will define the Objective-C method -(int)foo:(int)bar:(id)stuff:(id)do:(NSNumber *) on MLKMyClass instances: (define-objective-c-generic-function #/foo:bar:stuff:do: (self y z a b)) (define-objective-c-method #/foo:bar:stuff:do: :int ((self ns::mlk-my-class) (y :int) z a (b ns::ns-number)) (format t "Hello! Z and A are ~A and~&~A, respectively. Have a nice day." z a) (+ y 20)) Usage example: OBJECTIVE-CL> (invoke (invoke (find-objc-class 'mlk-my-class) 'new) :foo 3 :bar "abc" :stuff 3 :do 33) Hello! Z and A are #<NS:GSC-BUFFER-STRING `abc' {8230318}> and #<NS:GS-CACHED-INT `3' {812C5D0}>, respectively. Have a nice day. 23 Note that, at present, you absolutely have to call DEFINE-OBJECTIVE-C-GENERIC-FUNCTION before defining methods, because otherwise you're going to get the wrong type of generic function. All modifiers of the standard method combination should be supported in principle, but it's unlikey they'll work as expected. This is planned for a future release. &REST and &KEY arguments are not supported. #.(disable-method-syntax) ** Struct wrappers When an Objective-C method returns a struct, it is now wrapped in a FOREIGN-STRUCT; likewise for unions. If you want to prevent its automatic deallocation, you need to set its FOREIGN-VALUE-LISP-MANAGED-P property to false. This change has been made because it would otherwise not be safe to discard return values of Objective-C methods, a safety which both Objective-C and Lisp programmers have come to expect. ** COLLECT-CLASSES The new function COLLECT-CLASSES may be used to make all classes known to the Objective-C runtime available as CLOS classes under the NS namespace. In an ideal world, we'd do this automatically at system load-time, but registering such a large number of classes along with their metaclasses takes a long time on some CL implementations (CMUCL, SBCL), so it's the user's decision whether to use FIND-OBJC-CLASS for each class or COLLECT-CLASSES once for now. If you try the release out, please tell me what works and what doesn't. If you can't even get it to compile, that is helpful information as well. Of course, above all, have lots of fun! ~ Matthias _______________________________________________ objective-cl-announce mailing list objective-cl-announce(a)common-lisp.net http://common-lisp.net/cgi-bin/mailman/listinfo/objective-cl-announce
