Re: [Plplot-devel] Questions about the Lua bindings and examples
I have now implemented full testing of the Lua examples in the installed examples tree (using make test there). If anybody else wants to try this use -DENABLE_lua=ON. Examples 1 and 8 have been added to the list of what is tested (since they no longer have run-time errors). Since Lua example 1 is now run, no touch workarounds are needed any more to get ctest in the build tree or make test in the installed examples tree to work Here are the present results: lua Missing examples: 09 14 14a 15 16 17 19 20 21 22 23 25 26 27 28 29 30 31 Differing postscript output : 08 11 12 13 18 Missing stdout : Differing stdout : The examples actually run for this test (see plplot_test/test_lua.sh.in) are now 01 02 03 04 05 06 07 08 10 11 12 13 18 24 which implies 01 02 03 04 05 06 07 10 24 are now perfect.

Re: [Plplot-devel] Questions about the Lua bindings and examples
Hi Alan, thanks a lot for the test script. This helps a lot! I now (revision 9415) have ctest implemented for Lua. [ ] are currently perfect. Can you run ctest with the suggested workaround for missing example 01 to confirm these results as well? The current result of roughly one- fourth the Lua examples being perfect is excellent for this early in the game. Indeed, you are working quite hard on extending and updating the Lua examples so with luck the list of perfect Lua examples should rapidly increase in the next little while. I'm just trying to run the test. One note: in lua.cmake you use VERSION_LESS but this is obviously not available for cmake 2.6.0 which is installed by default on Ubuntu 8.10.

Hi Werner: I now (revision 9415) have ctest implemented for Lua. I had to remove the following examples from ctest (see plplot-test/test_lua.sh.in) # 01, 08, 09, 15, 16, 19, 22, 25, 30 are implemented but do not currently work (various run-time errors). # 14, 17, 20, 21, 23, 26, 27, 28, 29, 31 are not implemented. That left the following list the ctest currently looks at: 02 03 04 05 06 07 10 11 12 13 18 24 Since 01 is not on that list, the test_diff.sh logic does not work correctly (it assumes if 01 is missing the whole language is missing). To work around that issue until example 1 can be added to the list of examples without run-time errors you must run touch plplot_test/x01lua.psc plplot_test/x01lua_psc.txt from the top of the build tree to fool ctest -R compare (i.e., test_diff.sh) into running the lua comparison. With that workaround the current ctest results are as follows: lua Missing examples: 08 09 14 14a 15 16 17 19 20 21 22 23 25 26 27 28 29 30 31 Differing postscript output : 01 03 11 12 13 18 Missing stdout : Differing stdout: 01 So from the above list of examples that ctest runs and the subset of those where postscript output differs, Lua examples 02 04 05 06 07 10 24 are currently perfect. Can you run ctest with the suggested workaround for missing example 01 to confirm these results as well?

The HAVE_lua51 default is OFF (i.e., by default the build will proceed for lua-5.0). When I built for lua-5.0, the instructions above succeeded. Specifically, if I execute from the build-tree version of bindings/lua lua ../../../plplot_cmake/examples/lua/x05.lua -dev xwin I got the expected results. However, when I built for lua-5.1 and followed the same run-time instructions I got an error, e.g., softw...@raven lua ../../../plplot_cmake/examples/lua/x05.lua -dev xwin lua: Table doesn't contain key 'n'. stack traceback: [C]: in function 'parseopts' ../../../plplot_cmake/examples/lua/x05.lua:23: in main chunk [C]: ? Probably you will want to concentrate on 5.0 for now, but at some point it would be nice to get 5.1 working as well for the current examples. Note, I have all required packages for lua5.0 and lua5.1 installed from Debian testing, and I use the update-alternatives Debian system script to symlink /usr/bin/lua to the correct lua version for the type of build I want to do. Not perfect, but at least for lua 5.0 there is no easy way to tell lua where the shared library is (apart from setting an absolut path in the source). I think we should solve that problem in a similar way to what we do for python. Every python example imports a file that is configured to tell it the absolute location of the required python modules. The file is configured differently depending if it is for the build tree or install tree version. For the Lua case, I suggest we include a file that is configured with the correct absolute location (build tree location for now) of plplotluac. A quick google search indicates there is something called dofile for including a file into a lua script. If you agree that is the right way to deal with this situation, I can do the rest to get lua example scripts that work from the examples/lua directory. Once that is accomplished, it is a relatively small step to getting ctest for lua working. Alan __ Alan W.

Re: [Plplot-devel] Questions about the Lua bindings and examples
Hi Alan, On 24.01.2009, at 23:20, Alan W. Irwin wrote: Hi Werner: I have some questions about your Lua bindings and examples. * Are the bindings specific to Lua 5.0? Not really, but I only test the bindings and the examples with lua 5.0 at the moment. I made a test with lua 5.1 in an earlier stage and it was also working. Reason is, that I have bought the Lua Book (Programming in Lua) some time ago (5.0) and that this manual is also now free to browse: http://www.lua.org/pil/ . For lua 5.1 there is only the reference manual ( http://www.lua.org/manual/ ) and although there were not so much significant changes between 5.0 and 5.1 I still stick to 5.0 in the moment (since I have the book). Since many people still use 5.0 I want the lua bindings work for both 5.0 and 5.1. With a small build-system change I made locally, I was able to get the bindings to build for Lua-5.1 (the latest Lua version on Debian testing). However, I don't know whether they will work. I can switch back to Lua-5.0 if necessary, but I would be willing to try 5.1 if you feel there is a good chance it will work. It should actually work. If it compiles you made the first step and the example should actually run on 5.0 and 5.1. I also propose that either 5.0 or 5.1 is the default and if you want to use the non default lua interpreter you need to set a -DWITH_LUA50=ON option or something similar. * Should your version check for exactly 5.0 in each example be changed to 5.0 or greater? (This is related to the first question.) No, this should be like that. 5.1 provided significantly progress in loading shared libraries, so the header part in the examples is needed that the examples run with 5.0 and 5.1. Older lua versions are not supported (at least not tested, the 4.x versions are really old). * How do you run the examples? * Enable lua bindings with -DENABLE_lua=ON * lua, lualib, lualiblib must be installed, plus developer packages (Ubuntu/Debian) * cd build-directory/bindings/lua (here you should find plplotluac.so) * lua source-directory/examples/lua/x05.lua Not perfect, but at least for lua 5.0 there is no easy way to tell lua where the shared library is (apart from setting an absolut path in the source). Lua 5.1 allows to set an environment variable where lua looks for the shared library (I don't know which), therefor you could run the examples anywhere you want. Also some of the examples where not fully ported (e.g. x01 and x08) but already committed since I already did some work. So don't expect all committed examples to run. * Do you need help putting the test infrastructure (ctest and install-tree equivalent) in place? This would be great, especially since I have not much experience with the testing scripts. I was thinking about configuring the lua examples with a @MODULEPATH variable which is set via cmake to the directory where the lua bindings are, so that the examples could be run from anywhere. Or something like that. For 5.1 this wouldn't be needed since you could set the enviroment variable. I would be happy to help with that once I know how to run the examples. This would be great.
