The peculiar markup above is included in +; this header for muse-mode to be able to format this change log as an +; HTML file intended for publication on the project web site. + +---- + +Context: [[http://matthias.benkard.de/objective-cl][The Objective-CL Project]]. + +---- + +* 0.2.2 (?) + + - CMUCL compatibility has been restored. + - The function IN-METHOD-SYNTAX has been added. It's like + ENABLE-METHOD-SYNTAX except that it does not store the original + syntax to be restored by DISABLE-METHOD-SYNTAX later. Use this for + file-local readtable changes (as opposed to code-block-local ones). + - =NSArray= implements the generic sequence protocol on SBCL. + - Initialisation behaviour has changed on GNUstep. This should fix + some potential crashes related to =NSBundle=. + - A number of compilation errors on AMD64 machines have been fixed. + - CFFI 0.9.2 is supported. Previously, a Darcs checkout of CFFI had to + be used. + - Method invocation speed has improved. + + +* 0.2.1 (2008-03-07) + + - Objective-C instances and selectors returned by method callbacks are + converted into pointers correctly. + - All class definitions done through DEFINE-OBJECTIVE-C-CLASS make the + class name be interned in the OBJECTIVE-C-CLASSES package. + - Foreign Lisp value wrapper types =MLKLispString=, =MLKLispArray=, and + =MLKLispList= have been implemented and are used automatically when + passing Lisp values to foreign code. + - Add function SUPER. Methods can call it in order to do a super call. + - Lisp-managed Objective-C instances are not destroyed all of a sudden + by the Lisp garbage collector. + - Methods with a void return type don't return anything. + - DEFINE-OBJECTIVE-C-GENERIC-FUNCTION calls have been made obsolete by + a more prudent version of DEFINE-OBJECTIVE-C-METHOD. + + +* 0.2.0 (2008-03-05) + + - LOW-LEVEL-INVOKE and PRIMITIVE-INVOKE have been unified. + - Initialisation is more robust than before. + - char and BOOL return values are distinguished by an explicit policy + rather than naively treating all chars as BOOLs. + - Type handling has been improved, especially in those cases where the + actual type and the nominal type differ (e.g. what the runtime tells + us are chars are actually ints). + - Passing booleans to methods as arguments does the right thing. + - In theory, structs and unions can be returned by methods, which used + to be unsupported. In practise, this support is untested. + - The user is now able to define Objective-C classes from Lisp. + - The build system is both more robust and faster than before. The + speed improvement is achieved by trying to use the system's `cp' + command before falling back to manual copying. + - The function COLLECT-CLASSES has been added. Its purpose is to + collect and register (i.e. intern) all classes known to the + Objective-C runtime on the Lisp side. + - Whereas before, just about any version of libffi sufficed, libffi 3.x + is now required for its much improved closure support. Accordingly, + the included version of libffi has been updated to 3.0.4. Note that + this change in requirements will cause Leopard's integrated version + of libffi to be rejected by the build system. + - The user is now able to define Objective-C methods from Lisp. + - CMUCL is not supported in this release. + + +* 0.1.1 (2008-02-11) + + - CLISP compatibility is finally a reality. + - 0.1.0's build system was broken by choosing to run `make' in the + wrong directory, thereby neglecting to run `configure' if needed. + This has been fixed. + + +* 0.1.0 (2008-02-10) + + - The Objective-C 2.0 runtime is supported (in theory, at least; no one + is known to have tested the support so far). + - Objective-C classes are mapped onto CLOS classes via the MOP. + Metaclasses are likewise mapped to CLOS metaclasses. Foreign slots + can be accessed by way of SLOT-VALUE. + - Selectors have been made funcallable. + - On the NeXT runtime, bit fields don't confuse the type specification + parser anymore. + - All internal method calls have been made independent of the + READTABLE-CASE setting. + + +* 0.0.3 (2008-01-27) + + - The build procedure now tries to use a preinstalled libffi, if such a + thing can be found on the system. + + +* 0.0.2 (2008-01-26) + + - The libffi build procedure used to be buggy on Mac OS X. It should + work now. + + +* 0.0.1 (2008-01-26) + + - This is the first public release. + - We've got method invocation and object instantiation. More is + planned for later. + + +---- + +*Matthias Benkard, <lisp>(format-time-string "%Y-%m-%d, %k:%M %Z")</lisp>* + +http://matthias.benkard.de/ + +; Local Variables: +; mode: muse +; End: |
