Announce of 1.3.1
by Gustaf Neumann 26 Aug '04

26 Aug '04

Dear XOTcl Community, This is a minor fix release relative to 1.3.0. This release fixes a few problems introduced in 1.3.0 (invocation of checking procs in nonpositional argument) and has a better build support for building XOTcl outside of the source tree, the tar files are now dist-cleaned. Best regards, Gustaf Neumann Uwe Zdun -- Univ.Prof. Dr.Gustaf Neumann Abteilung für Wirtschaftsinformatik und Neue Medien Wirtschaftsuniversität Wien, Augasse 2-6, 1090 Wien

Use of TclGetInterpProc
by Neil Madden 26 Aug '04

26 Aug '04

Hi all, I've just been compiling XOTcl 1.3.0 on Mac OS X against the latest (as of about an hour ago) CVS HEAD versions of Tcl and Tk. It initially failed on the final linking stages, missing the TclGetInterpProc function. This function has been taken out of Tcl in CVS. Commenting out the 1 reference to this function in the XOTcl sources (generic/xotcl.c line 10461) allows the compile to finish, all the tests pass and the resulting library seems fine. Talking to Donald Porter on the Tcl'ers Chat indicates that use of this function should no longer be necessary as Tcl doesn't create any procs using the old string-based interfaces anymore. Just thought I'd send out a heads-up, as you probably want to fix/alter the XOTcl code to deal with this. Cheers, Neil.

XOTcl 1.3.0 available
by Gustaf Neumann 19 Aug '04

19 Aug '04

Dear XOTcl Community, i am proud to announce the availability of XOTcl 1.3.0. Major changes relative to 1.2.0 are: - Qualitative Improvements * Improved portability: + TEA3 compatible build + Much more polished configure+makefile (many thanks to Jim Lynch for his help) * Improved code quality: + fixed 2 possible segmentation violations (error handling) + fixed free memory reads (many thanks to Zoran Vasiljevic for his help with purify) * Less intrusive usage of XOTcl components: + XOTcl procs and instprocs use now the namespace in which they were defined. One can use XOTcl packages without having the need to import xotcl globally or to use the xotcl-prefix in all xotcl procs/instprocs. - Functional Improvements * New forwarding mechanisms for fast delegation: new methods 'forward' and 'instforward' (many thanks to Bryan Schofield for fruitful discussions and suggestions). This method is a superset of tclcmd/insttclcmd, which has been marked as deprecated. See the tutorial for more details. * Nonpositional arguments for xotcl procs/instprocs; this is a flexible way to check arguments, to provide defaults etc for every xotcl proc/instproc. It uses a similar syntax as ad_proc and ad_page_contract in OACS. See the tutorial for more details. * Extended methods filter, mixin, instfilter, instmixin as discussed in the XOTcl mailing list. These commands can be used more flexibly as follows obj mixin same as: obj info mixin obj mixin {C1 C2} same as: obj mixin set {C1 C2} obj mixin set {C1 C2} sets the mixins for obj obj mixin get same as: obj info mixin obj mixin add C3 adds a mixin on front of the mixin list obj mixin add C3 end adds a mixin at the end the mixin list obj mixin add C3 3 adds a mixin at the 3rd position obj mixin delete ::C3 removes the mixin from the mixin list The same semantics are available as well for filter, instmixin and instfilter. This change is fully backward compatible. {filter,instfilter,mixin,instmixin}append are deprecated now. For more details about the changes, please consult the ChangeLog and documentation. MORE INFO General and more detailed information about XOTcl and its components can be found at http://www.xotcl.org Best regards, Gustaf Neumann Uwe Zdun -- Univ.Prof. Dr.Gustaf Neumann Abteilung für Wirtschaftsinformatik und Neue Medien Wirtschaftsuniversität Wien, Augasse 2-6, 1090 Wien
