Announcement: Next Scripting Framework 2.0b3 available
by Gustaf Neumann 10 Jun '13

10 Jun '13

Dear Community, We are pleased to announce the availability of the Next Scripting Framework 2.0b3 which can be obtained from http://next-scripting.org Best regards - Gustaf Neumann - Stefan Sobernig =============================================== Announcing NSF 2.0b3 ************************* Major changes relative to NSF 2.0b2 are: * Additional Features: - object parameters: call method "assign" on slot objects, when it is provided - include "-returns" in introspection for aliases and scripted methods. New subcommand "info method returns" for nx. - better compatibility with XOTcl 1.*: * invocation of objects via method interface follows per default the XOTcl 1.* conventions. In order to obtain the semantics of ensemble objects, the object properties "keepcallerself" and "perobjectdispatch" have to be used. * better handling of XOTcl 1.* configure commands (starting with a "-") when list property is lost (Many thanks to Zoran Vasjljevic for the good example) * use different version numbers in serializer to avoid mixups between XOTcl 1 and XOTcl 2 when both packages are installed * Improved Code Quality: - improved performance * rewrite of alias handling (alias reform) * improved branch prediction * significant speedup for handling large numbers of subclasses (subclass reform), avoid repetitious computations * significant speedup on mass-destroy (e.g. on thread exit) - provide better protection for deletion/overwriting of base classes - fixed potential duplicates on diamond inheritance - fixed unknown handling for "-local" and "-system" dispatches - improved compatibility for windows compilations (c89, __WIN32__) - fixed potential crashes * during method caching * error messages * implicit deletions - follow Tcl convention on error messages (start always with lower case) - better handling of multiple errors in a single command. - return GMT dates in Httpd as RFCs require * Improved documentation - fixed typos, improve wordings * Extended regression tests MORE INFO General and more detailed information about the Next Scripting Framework and its components can be found at http://next-scripting.org

NX on windows
by Jonathan Kelly 31 Jul '12

31 Jul '12

Hi, I'm trying to get nx working under windows. I was using Activestate 8.5 on an XP box ... and following the suggestion on the website I installed MSVisualStudio 10.0 express ... but I couldn't see how to get that to work ... there isn't a Makefile ... I had downloaded nsf2.0b3 So I thought I'd try cygwin (which I already use for other purposes). I installed the compile tools, and ran configure, but it broke because I apparently don't have a /usr/local/include/tcl8.5/tools/genStub.tcl ... I took a gamble and downloaded a version I found on the web somewhere, and then configure ran but with some warning messages. Make then breaks with this ./generic/nsfError.c:116: error: conflicting types for 'NsfPrintError' ./generic/nsfDecls.h:73: error: previous declaration of 'NsfPrintError' was here ./generic/nsfError.c:116: error: conflicting types for 'NsfPrintError' ./generic/nsfDecls.h:73: error: previous declaration of 'NsfPrintError' was here Makefile:575: recipe for target `nsfError.o' failed I'm happy to be the guinea pig for getting the "use NX on windows" instructions to be useable. Or should I just use XOTcl ... ? Thanks Jon.

Hello Gustaff, What is the reason for following error/behavior: ClassX create c1; #ClassX has several subclasses c1 delete method m1 Error: ::c1: cannot delete object specific method m1 I get a similar error for "c1 delete property p1" Why am I not able to delete object specific methods/properties? Thanks
