main.cpp.rst files are not handled by generate script

[Chaffra Affouda]

Hi, How do I convert the main.cpp.rst files to main.cpp now? Is this feature still being worked on? I can't build the latest trunk.

[Martin Sandve Alnæs]

There's a script ./cmake/scripts/generate-demo-files, it should be executed when you run cmake.

To convert just one .rst file you're editing you can run python <dolfin>/utils/pylit/pylit.py on the file.

[Chaffra Affouda]

Yes that script is missing a line to convert .cpp.rst files.

rstfiles += [f for f in files if len(f) > 8 and f[-8:] == ".cpp.rst"]

[Martin Sandve Alnæs]

It's done in CMakeLists.txt.

[Martin Sandve Alnæs]

Also, the GLOBRECURSE mechanism in CMakeLists.txt converts more files than it should, including e.g. other build directories.

[Chaffra Affouda]

Maybe this is not working on MSYS2 then.

When running cmake, do you see this?

I am seeing this

Then the code in CMakeLists.txt doesn't work for you... No idea why.

[Chaffra Affouda]

yes on windows you should problaby specify the python exe like this

execute_process(COMMAND ${PYTHON_EXECUTABLE} ./utils/pylit/pylit.py ${rst_file}

in the `CMakeLists.txt'. It works from cmake now.

I would like to run pylit via the Python interpreter, but we need to check that it works with py3.

[Martin Sandve Alnæs]

It does with the edits I made recently.

[Prof Garth Wells]

Great, I'll make the change then.

[Martin Sandve Alnæs]

I had to fix pylit when trying to build dolfin with py3, because I was using a virtualenv where python=python3. It's good to keep this in mind: don't trust that python=python2.

[Prof Garth Wells]

I've started avoiding python and pip in favour of python2, python3, etc, because of inconsistencies across platforms.

[Prof Garth Wells]

Use detected Python interpreter when running pylit. Fixes #755.
