Next Scripting Framework
by Gustaf Neumann 27 Oct '11

27 Oct '11

Dear XOTcl community, today, we presented the Next Scripting Framework (NSF) at the 8th Annual Tcl/Tk Conference at Manassas, Virginia. We are proud to announce also here the availability of nsf 2.0b2, available from the web-site below, that went as well public today. The release plan is to gather in the first round feedback from the inner community and to polish the website and documentation in the meantime. The full public release will come out without the beta-state and will be annouced to the wider public. The distribution of the next scripting framework contains essentially - NSF, the low-level framework - XOTcl 2.0 - NX (descendant of XOTcl) While XOTcl 2.0 is primarily highly compatible with XOTcl 1.6, NX provides more support for programming the larger, such as stronger encapsulation, method protection, modular feature composition, etc. For more details, consult the slides referenced below. The website contains a more detailed NX migration guide comparing XOTcl idioms with NX idoms, or an NX tutorial. The Next Scripting Framework requires Tcl 8.5 or newer and is released under an MIT license. For users bound for the time being to Tcl 8.4 we will continue to release bug fixes for the XOTcl 1.6 series. web-site: http://next-scripting.org/ slides: http://nm.wu-wien.ac.at/research/publications/b885.pdf Gustaf Neumann Stefan Sobernig -- Univ.Prof. Dr. Gustaf Neumann Institute of Information Systems and New Media WU Vienna Augasse 2-6, A-1090 Vienna, AUSTRIA

NX memory leak
by Kristen Eisenberg 23 Oct '11

23 Oct '11

Hello Gustaf, I am using the latest Tcl 8.6 from SourceForge and latest NX on 32bit Linux. I am experiencing a pretty bad memory leak when using NX objects with attributes. Example code: time {Object create o; o attribute "[clock clicks] [clock clicks]";o destroy} 1000000 Within like 3 minutes the memory usage grows to around 300meg.
