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

[Maurice L. <mj...@ga...>]

The changes I've just committed enable easy loading of all three kinds, from
both the tmp/ dir and the install tree.  I've given the prescription for the
tmp/ dir only; in the install tree you must:
 - change the auto_path setting appropriately (or use a tclsh/wish
   under the same $prefix)
 - first cd to the appropriate examples/xxx dir.

Under plplot/tmp/:

tclsh
lappend auto_path .
package require Pltcl
plinit
source tcldemos.tcl
1
2
...

wish
lappend auto_path .
package require Pltk
source tkdemos.tcl
1
2
...

wish
lappend auto_path .
package require Plplotter
source runAllDemos.tcl
<control from gui>

The way this is done is as follows.

Since there are 3 ways of loading, there are 3 pkgIndex.tcl.in files, one for
each dir under bindings/.  They are very similar but have slightly different
parameters, and should be easy enough to understand & modify.

I gave them the ".in" extension to distinguish them from ordinary tcl files --
I don't want them in the tclIndex or being installed with the others.  Rather,
they are concatenated to get the real pkgIndex.tcl file.  So this is done
during configure to get the pkgIndex.tcl under tmp/, and again during install
to get the one under $prefix/lib/plplot$version/.
