To Maurice, Arjen, and/or James Tappin: I am primarily addressing this appeal to you guys because you are the only ones I know with some combined PLplot and Tcl/Tk expertise.
In order to finish off some Tcl/Tk8.6 + itcl/itk/iwidgets version 4 testing work, I need some global way to effectively replace package require Itcl package require Itk package require Iwidgets everywhere it occurs in our code with either package require Itcl 3.0 package require Itk 3.0 package require Iwidgets 3.0 OR package require itcl 4.0.0 package require itk 4.0.0 package require iwidgets 4.0.0 I am thinking along the lines of setting some global variables such as itcl_package_name itk_package_name iwidgets_package_name with the appropriate values for version 3 or version 4, but I don't know whether that is possible with Tcl. As an experiment, I did try using set itk_package_name "itk 4.0.0" in bindings/tk/pkgIndex.tcl and I attempted to access that variable in examples/tk/tk02 using global itk_package_name puts "$itk_package_name" But the result errored out with can't read "itk_package_name": no such variable while executing "puts "$itk_package_name"" The goal here is to make it easy for the user to choose between using either version 3 of [incr Tcl_tk] or version 4. In fact, my testing of those two cases is being held up because I don't have an easy way to switch between them (without a lot of code editing). So some quick help on how to make this possible would be appreciated. Alan __________________________ Alan W.
