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.
