Hey guys,
First of all, thanks to Sergei for bringing the issue (bug #724816) at
the table!
Regarding bug #724816, we would like to initiate a transition from the
XOTcl to its successor NSF:
http://next-scripting.org/
NSF is a shared infrastructure for both XOTcl 2.* (which is the direct
successor of XOTcl 1.6.*) and NX, which adds a completely revamped
language design. Using NSF, both XOTcl 2.* and NX come fully scripted
(i.e., each language comes as a purely scripted Tcl package). NSF (and
therefore XOTcl 2 and NX) require at least Tcl 8.5, but are also upward
compatible and tested with Tcl 8.6.
NSF has been in use for over a year now in several production systems:
It drives http://openacs.org/ and one of the largest university
eLearning sites in Europe: http://learn.wu.ac.at/
As Sergei pointed out correctly, the XOTcl 1.* line does not build
anymore with Tcl 8.6; and we do not intend to establish and to further
maintain this compatibility given that there is a replacement: NSF and
XOTcl 2.
How can we best prepare and perform the transition? Is there a chance to
meet the Nov 5th deadline, somehow?
1) I have started creating a new debian package "nsf" which will contain
the binary and scripted components of NSF, NX, and XOTcl 2. I base this
on the infrastructure already established for the xotcl package (debian/*).
I will have completed this by tomorrow evening, most probably. Can I
count on someone reviewing and promoting the package, then?
Have there been critical updates to the Tcl/Tk package maintainer
guidelines which I should consider?
2) I will prepare an update for the "xotcl" package, to align the
dependencies:
"xotcl" will depend on: tcl 8.4/8.5, tk 8.4/8.5
"nsf" will require: tcl 8.5+/ tk 8.5+
Note that "xotcl" and "nsf" (once installed) can coexist (e.g., under
tcl 8.5 environment) since the Tcl package versions clearly discriminate
between the two lines. Under 8.4 (if still relevant) and 8.6,
respectively, they will be mutually exclusive because of the distinct
runtime dependencies.
Is there anything I am missing from my "transition picture"?
Thank you all and all the best,
Stefan
