* wrap/python/spot.py: Add the unabbreviate() method, and
remove unabbrivate_ltl() and get_literal().
* wrap/python/tests/randltl.ipynb: Demonstrate unabbreviate().
This additionally fixes#107.
* src/bin/ltlgrind.cc: Fix handling for FILEANAME/COL. Document FORMAT
in --help. Assume -F for arguments given without options.
* src/tests/ltlgrind.test: Add two tests.
* NEWS: Mention this.
This is motivated by an email from Fanda.
* src/bin/common_post.cc, src/bin/common_post.hh: Add variables to
detect when level or pref are sets.
* src/bin/autfilt.cc: Adjust default for pref/sets.
* src/tests/readsave.test: Add test cases.
* NEWS: Mention it.
* src/twaalgos/randomgraph.cc: Replace an assertion by an exception.
* src/bin/randaut.cc: Diagnose -Q0.
* src/tests/randaut.test: Test it.
* NEWS: Mention the bug.
* src/twaalgos/sccfilter.hh,
src/twaalgos/sccfilter.cc (scc_filter_states): Remove useless acceptance
marks while preserving state-based acceptance. Add a new argument
to specify if all useless mark have to be removed, like for scc_filter.
* src/twaalgos/simulation.cc: Use the new parameter.
* src/twaalgos/postproc.cc: Likewise. Also call do_scc_filter even
after WDBA simplification to cleanup trivial SCCs. Preserve state-based
acceptance for weak automata.
* src/tests/readsave.test: Add one test.
* src/tests/dstar.test, src/tests/prodor.test, src/tests/remfin.test,
src/tests/sim3.test, wrap/python/tests/automata.ipynb,
wrap/python/tests/piperead.ipynb: Adjust expected output.
* NEWS: Mention the change.
The previous code was sometime doing the work of remove_fin() in
addition to complementing the acceptance conditions. This separate
the two operations clearly. Also the specialized code for
complementing weak automata is now a specialized code for remove_fin()
on weak automata.
* src/twaalgos/dtgbacomp.hh, src/twaalgos/dtgbacomp.cc: Rename as ...
* src/twaalgos/complement.hh, src/twaalgos/complement.cc: ... these.
* src/twaalgos/Makefile.am: Adjust.
* src/twaalgos/complement.hh (dtgba_complement): Rename as ...
(dtwa_complement): ... this, and restrict the purpose to completion
and accetance complementation. Further acceptance simplification
can be done with remove_fin() and to_generalized_buchi().
* src/twaalgos/remfin.cc (remove_fin): Specialize handling of weak
automata using the code that was originally in dtgba_complement().
Also mark the output as state-based when the input has to Inf.
* src/twaalgos/postproc.cc, src/twaalgos/postproc.hh: Make sure
scc_filter is always called after to_generalized_buchi().
* bench/stutter/stutter_invariance_randomgraph.cc,
src/bin/ltlcross.cc, src/tests/ikwiad.cc, src/twaalgos/minimize.cc,
src/twaalgos/powerset.cc, src/twaalgos/stutter.cc: Adjust usage.
* src/tests/dstar.test, src/tests/ltl2dstar4.test,
src/tests/remfin.test: Adjust expected outputs.
* wrap/python/spot_impl.i: Export dtwa_complement().
* wrap/python/spot.py: Python 3.5 reports some unexpected SystemError
messages when the stack of iterator(...(iterator(generator))) we build
for random LTL generation raises a StopIteration. The messages are
attached either to delete_formula or delete_randltlgenerator, claiming
that these functions exit with an error; but I have checked that they
do not. I've been unable to understand the cause of the issue.
Replacing the generator by an iterator at least fixes the problem in a
way that is transparent for our API.
* wrap/python/tests/randltl.ipynb: Adjust expected formulas.
* src/twaalgos/postproc.hh: Allow the formula not to be specified. The
code already support that, as it is called with an explicit nullptr in
autfilt (for example), but not requiring the nullptr is better for the
Python bindings.
* src/twaalgos/complete.cc, src/twaalgos/complete.hh
(tgba_complete, tgba_complete_here): Rename as...
(complete, complete_here): ... these. Also fix useless output of
acceptance marks on transition leading to the sink when the automaton
does not use state-based acceptance.
* src/tests/ikwiad.cc, src/twaalgos/dtgbacomp.cc,
src/twaalgos/dtgbasat.cc, src/twaalgos/postproc.cc,
src/twaalgos/product.cc: Adjust.
* wrap/python/spot_impl.i: Export these function.
* wrap/python/tests/automata.ipynb: Test spot.complete().
It was only needed with Swig versions older than what we have now.
* src/misc/common.hh: Here.
* src/misc/bitvect.hh, src/misc/common.hh, src/ta/taexplicit.hh,
src/ta/taproduct.hh, src/tl/simplify.hh, src/twa/bdddict.hh,
src/twa/taatgba.hh, src/twa/twaproduct.hh: Use = delete directly.
* src/twaalgos/dupexp.cc, src/twaalgos/dupexp.hh: Rename to...
* src/twaalgos/copy.cc, src/twaalgos/copy.hh: ... these.
Get rid of dupexp_bfs, rename dupexp_dfs as copy, and add
an option to preserve named states.
* src/twaalgos/Makefile.am, src/tests/dupexp.test,
src/tests/ikwiad.cc, src/tests/sccsimpl.test,
src/twa/twagraph.hh, src/twaalgos/dot.cc,
src/twaalgos/stutter.cc, wrap/python/spot_impl.i: Adjust.
* NEWS: Mention this change.
* src/twa/bddprint.cc: Do not store a global shared_ptr to the bdddict
used for printing (a simple pointer is enough), otherwise it risks being
the last shared_ptr to be destroyed, and it might be destroyed after the
unicity maps of the formulas.
Swig 3.0.2 (currently installed by Debian), install strongly typed
enumerator in the main namespace instead of in its own namespace.
This is fixed in latter versions of Swig.
* wrap/python/spot.py: If spot.op does not exists, populated it with all
operators from the spot namespace.
* wrap/python/tests/ltlsimple.py: Use operators from spot.op.
