[Plplot-devel] Prescriptions for running tkdemos.tcl under wish and tcldemos.tcl under tclsh

[Alan W. I. <ir...@be...>]

While writing e-mail to Geoffrey on the current status of PLplot, I had a
blinding flash of insight....;-)

A side benefit of the current library changes is we can now run tkdemos.tcl
from wish and tcldemos.tcl from tclsh! (This was the major motivation for
working on the tea branch for me.)

Here is the wish/tkdemos.tcl prescription from plplot/tmp:

wish

load drivers/tkd_drv.so Pltk
package require Pltk
source tkdemos.tcl

1
2
3
.....

Please try this for yourself as well. Note, that the version string that the
package require comes back with is 4.99 so something has to be changed to
address that (minor?) issue.

Here is the tclsh/tcldemos.tcl prescription from plplot/tmp:

tclsh

load ./libplplottcltkd.so.5.1.0 Pltcl
package require Pltcl
plinit
source tcldemos.tcl

1
2
3
.....

Please try this for yourself as well. Here the version string returned by
the package require command is correct.

Also some changes will have to be done to the files which set up tcl/tk so
that the package require commands will work without the prior load commands
both for the plplot/tmp and installed versions.  However, I will leave that
internal tcl/tk configuration issue to the tcl/tk experts here.

The important thing to recognize here is that we are now in a position to
run our tk examples directly from a tk environment (wish) and our tcl
examples directly from a tcl environment (tclsh) much in the same way that
we run our python examples directly from python.  Personally, I think this
is an idea our users will understand better than demanding they use special
executables (plserver instead of wish and pltcl instead of tclsh) to gain
access to plplot from tcl/tk.
