Newer Jupyter version are able to capture the system's stdout and
stderr to display it in the notebook. This is done asynchronously,
with a thread polling those file descriptor. While this will help us
debug (finaly we can see the tracing code we put in C++) this causes
two issues for testing. One is the asynchronous behaviour, which
makes it very hard to reproduce notebooks. The second issue is that
older version of Jupyter used to hide some of the prints from the
notebook, so it is hard to accommodate both.
In the case of the ltsmin-pml notebook, loading the PML file from
a filename used to trigger a compilation silently (with output on the
console, but not in the notebook). The newer version had the output
of that compilation spread into two cells.
* python/spot/ltsmin.i: Work around the issue by triggering the
compilation from Python, and capturing its output explicitly, so it
work with all Jupyter versions. Also adjust to use the more recent
and simpler subprocess.run() interface, available since Python 3.5.
* tests/python/ltsmin-pml.ipynb: Adjust expected output.
* tests/python/ipnbdoctest.py (canonicalize): Adjust patterns.
* python/spot/aux.py (rm_f): new function.
* python/spot/ltsmin.i: Replace the %require magic by a simple function.
Rewrite the %%dve magic.
* tests/python/otfcrash.py: Simplify using spot.ltsmin.require()
* tests/python/ltsmin.ipynb: Likewise, also add more text for the
documentation.
* NEWS: Adjust.
* spot/ltsmin/ltsmin.hh, spot/ltsmin/ltsmin.cc: Expose more of the
ltsmin interface.
* python/spot/ltsmin.i: Add some helper functions on top of this
new interface.
* tests/python/ltsmin.ipynb: Test them.
* NEWS: Mention it.
* spot/ltsmin/ltsmin.cc, spot/ltsmin/ltsmin.hh: Split load_ltsmin() into
ltsmin_model::load() and ltsmin_model::kripke(). Report errors using
exceptions instead of on std::cerr.
* python/spot/ltsmin.i: Deal with exceptions.
* tests/ltsmin/modelcheck.cc, tests/python/ltsmin.ipynb: Adjust.
* python/spot/ltsmin.i: New file.
* python/Makefile.am: Add it.
* python/spot/impl.i: Add bindings for kripke and fair_kripke.
* tests/python/ltsmin.ipynb: New file.
* tests/Makefile.am, doc/org/tut.org: Add it.
* tests/python/ipnbdoctest.py: Make it possible for notebook
to exit(77).
* debian/control: Make the Python package dependent
on libspotltsmin0.
* python/spot/__init__.py: Typo.
