This is the beginning of recorded history. Older changes:
* Guile no longer includes sophisticated Tcl/Tk support.
The old Tcl/Tk support was unsatisfying to us, because it required the
user to link against the Tcl library, as well as Tk and Guile. The
interface was also un-lispy, in that it preserved Tcl/Tk's practice of
referring to widgets by names, rather than exporting widgets to Scheme
code as a special datatype.
In the Usenix Tk Developer's Workshop held in July 1996, the Tcl/Tk
maintainers described some very interesting changes in progress to the
Tcl/Tk internals, which would facilitate clean interfaces between lone
Tk and other interpreters --- even for garbage-collected languages
like Scheme. They expected the new Tk to be publicly available in the
fall of 1996.
Since it seems that Guile might soon have a new, cleaner interface to
lone Tk, and that the old Guile/Tk glue code would probably need to be
completely rewritten, we (Jim Blandy and Richard Stallman) have
decided not to support the old code. We'll spend the time instead on
a good interface to the newer Tk, as soon as it is available.
