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]]. ---- * 0.2.3 (?) - 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). * 0.2.2 (2008-03-23) - CMUCL compatibility has been restored. - =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, (format-time-string "%Y-%m-%d, %k:%M %Z")* http://matthias.benkard.de/ ; Local Variables: ; mode: muse ; End:
