Yes, that means that the PostScript examples are run and found to result in the same PS files as for C. Puzzling in the sense that there _is_ a difference between the way those examples are run in the automated tests and the way you have run them. So Alan is at least partly right.

Is test_tcl_standard_examples a subset of test_noninteractive? To use more precise language CMake allows you to set up a dependency system between targets using the add_dependencies command. This means if target A depends on target B, running target A _forces target B to be run first_. The specific answer to your question is that the test_interactive target (as opposed to the test_noninteractive target you mentioned) depends on test_tcl_standard_examples. I think it is important for all PLplot developers to understand how the dependencies between test targets have been implement in examples/CMakeLists.txt so please look at that file to confirm the statements I make below. In that file we have add_dependencies(test_interactive ${interactive_targets_LIST}) where interactive_targets_LIST is a list of targets. Earlier in that file we have list(APPEND interactive_targets_LIST ${test_tcl_standard_examples}) So this means test_interactive depends on test_tcl_standard_examples. The test_interactive target also depends on many other interactive targets as you can see by looking for all instances of interactive_targets_LIST in examples/CMakeLists.txt. So if you want to execute a very specific test for how well tcl executes interactively with -dev xwin, run the test_tcl_standard_examples target. If you want that test run and also a lot of other interactive tests, then run the test_interactive target. The more general targets like test_interactive are best for comprehensive testing that everything interactive works properly, but in this case when we are trying to debug an issue, the more specific test you can run, the better. So please run test_tcl_standard_examples and report the results. While I am on this subject of dependencies in our test system, notice that examples/CMakeLists.txt also has the following commands (collected here but originally spread through the file in different order) add_dependencies(test_noninteractive ${noninteractive_targets_LIST}) set(noninteractive_targets_LIST test_diff_psc) add_dependencies(test_diff_psc ${diff_targets_LIST}) list(APPEND diff_targets_LIST test_${language}_psc) One of those languages (in the loop) is tcl. So test_noninteractive depends on test_diff which depends on test_tcl_psc (and many other test_${language}_psc targets in that loop). Note that test_diff is actually the target that produced the good noninteractive results for tcl you demonstrated above. That target runs every language with -dev psc and compares non-C results with the corresponding C results. The test_tcl_psc target is much simpler. It simply runs the tcl language results for -dev psc, but test_diff obviously won't work unless test_tcl_psc is run first to generate the required PostScript files for Tcl which is why we have set up test_diff_psc to depend on test_tcl_psc (and, in general, test_${language}_psc for all languages in the loop) in the above chain of dependencies. At this point I have no idea why the above automated way of running pltcl for -dev psc works, and your attempt to run pltcl by hand does not work. You would have to look at what test_tcl_psc actually does which is to look at the COMMAND associated with the custom command that is run by that custom target. It is easy to show that COMMAND runs the plplot-test.sh shell script which sets everything up and which in turn runs the test_tcl.sh shell script which runs pltcl. In any case because of the good noninteractive Tcl results you are getting with -dev psc as demonstrated by the test_tcl_psc and test_diff_psc targets results you show above, I expect you will also get good interactive results using the test_tcl_standard_examples target (for -dev xwin).

Hi Alan, Thanks for the patient explanation of the test dependencies. On Aug 29, 2012, at 9:33 AM, Alan W.

But please confirm that. Confirmed. The test ran in the X system, with the pictures flying by really fast. The only thing that I found odd was that beginning with the "cropped Lena" image, I had to move focus to the X window and hit Return four times, each time advancing to another modified Lena image, and at that point the plots updated once again without input by me. I don't have a dog in this (Tcl/Tk) race so I don't want to be a drag by pursuing this if nobody else is having a problem. I do think that my problems might also be shared by other OS X users and maybe we haven't had bug reports because OS X is a "minority OS" wrt PLplot and usage is light, or actual Tcl users are doing something that I don't know how to do. Does the Tk interactive method allow the user to use a mouse to interactively select a rectangular portion of the plot for zooming? This would certainly be useful and then I would have an actual personal interest in this work. Do any of the interactive devices allow this? X, Aquaterm and Qt do not--those are the only ones that I have tried. Jerry > > Alan |

It is because of the -np (no pause) option available with -dev xwin. > The only thing that I found odd was that beginning with the "cropped Lena" image, I had to move focus to the X window and hit Return four times, each time advancing to another modified Lena image, and at that point the plots updated once again without input by me. That is the same here. I have forgotten the details, but I believe the "Lena" example necessarily must turn off the no-pause option internally in order to work at all. So you have to hit return to get through it. After that example, (see examples/tcl/standard_examples.tcl.in) plpause 0 is executed ( http://plplot.sourceforge.net/docbook-manual/plplot-html-5.9.9/plspause.html) to disable pausing again. > I don't have a dog in this (Tcl/Tk) race so I don't want to be a drag by pursuing this if nobody else is having a problem.

No, your above test results indicate all is perfect with Tcl and -dev xwin on your system, and your prior test indicated all was perfect with Tcl and -dev psc on your system.
