* src/hoaparse/public.hh, src/hoaparse/parsedecl.hh,
src/hoaparse/hoascan.ll, src/hoaparse/hoaparse.yy: Implement this new
interface.
* wrap/python/spot.py (automata): Use it when the argument contains
a newline.
* wrap/python/tests/automata-io.ipynb: Test it.
Some tests calling spot.automaton('non-existing|') where failing either
with a "process returned 127", or, under heavier load, with "failed to
read from...". The latter occur if we poll() the exit status before the
children has had the tame to finish.
* wrap/python/spot.py: Make sure we wait for the child process if we
reach EOF, so that we can report the error status.
* wrap/python/tests/automata-io.ipynb, wrap/python/tests/piperead.ipynb:
Update.
* wrap/python/tests/run.in: Make it easier to run python with gdb.
* wrap/python/tests/automata-io.ipynb: Add test case.
* wrap/python/spot.py (spot.automata): Make sure p is defined in all
cases.
* src/hoaparse/hoascan.ll: Make sure we do not close a file that
hasn't been opened.
* src/hoaparse/fmterror.cc, src/hoaparse/public.hh,
src/hoaparse/hoaparse.yy (hoa_stream_parser::parse_strict): New method
that raises an exception whenever a syntax error is encountered.
* src/ltlparse/public.hh (parse_error): Move ...
* src/misc/common.hh: ... here.
* wrap/python/spot_impl.i: Wrap the hoa output.
* wrap/python/spot.py: Implement spot.automata.
* wrap/python/tests/automata-io.ipynb: New test.
* wrap/python/tests/Makefile.am: Add it.
