These rules come from Delag's paper, and help some cases
in issue #385.
* spot/tl/simplify.cc: Implement the simplification.
* doc/tl/tl.tex, NEWS: Document it.
* tests/core/385.test: New file.
* tests/Makefile.am: Add it.
* tests/core/reduccmp.test: More tests.
* tests/core/ltl2tgba2.test: Adjust one improved case.
* tests/python/automata.ipynb, tests/python/twagraph-internals.ipynb:
Adjust expected output, as the cnf/dnf reorder some subformulas.
* spot/twaalgos/alternation.cc, spot/twaalgos/alternation.hh,
spot/twaalgos/complement.cc, spot/twaalgos/complement.hh,
spot/twaalgos/determinize.cc, spot/twaalgos/determinize.hh,
spot/twaalgos/minimize.cc, spot/twaalgos/minimize.hh,
spot/twaalgos/postproc.cc, spot/twaalgos/postproc.hh,
spot/twaalgos/powerset.cc, spot/twaalgos/powerset.hh,
spot/twaalgos/product.cc, spot/twaalgos/product.hh: Use an
output_aborter argument to abort if the output is too large.
* bin/ltlcross.cc: Use complement() with an output_aborter
so that ltlcross will not attempt to build complement larger
than 500 states or 5000 edges. Add --determinize-max-states
and --determinize-max-edges options.
* tests/core/ltlcross3.test, tests/core/ltlcrossce2.test,
tests/core/sccsimpl.test, tests/core/wdba2.test,
tests/python/stutter-inv.ipynb: Adjust test cases.
* NEWS: Document this.
* bin/spot-x.cc: Add documentation for postprocessor's
det-max-states and det-max-edges arguments.
* doc/org/ltlcross.org: Update description.
This allows fixing issue #388 reported by Victor Khomenko.
* spot/twaalgos/word.cc, spot/twaalgos/word.hh (use_all_aps): New
method.
* tests/python/stutter-inv.ipynb: Use it.
* tests/python/stutter.py: New file, with Victor's test case.
* tests/Makefile.am: Add python/stutter.py.
The first issue was reported by Victor Khomenko.
* spot/tl/formula.cc: Introduce a single-argument
version of sugar_delay().
* spot/parsetl/parsetl.yy: Use it.
* doc/tl/tl.tex, spot/tl/formula.hh: Adjust doc.
* tests/core/ltlfilt.test, tests/core/sugar.test: More tests.
Following a discussion with Victor Khomenko.
* doc/tl/tl.tex: Document those rules.
* spot/tl/simplify.cc: Implement them.
* tests/core/reduccmp.test: Test them.
* spot/tl/formula.cc, spot/tl/formula.hh (formula::sugar_delay): New
function to implement this operator as syntactic sugar.
* spot/parsetl/parsetl.yy, spot/parsetl/scantl.ll: Parse it.
* doc/tl/tl.tex: Document the syntactic sugar rules and precedence.
* tests/core/sugar.test: Add tests.
* NEWS: Mention this new feature.
Since b[+] and [*0] are siSERE, b* is siSERE as well.
Suggested by Victor Khomenko.
* spot/tl/formula.cc: Implement that for Star and also
in the concatenation rule.
* tests/core/kind.test, tests/core/ltlfilt.test: Adjust.
Reported by Victor Khomenko.
* spot/tl/formula.cc: Rewrite the siPSL detection for ";".
* tests/core/ltlfilt.test: Add more tests.
* tests/core/kind.test: Adjust.
* NEWS: Mention the bug.
Report from David Müller.
* spot/twaalgos/simulation.cc: Add wrapper to deal with automata
sharing Fin/Inf sets.
* tests/core/ltl2tgba2.test: New test cases.
* NEWS: Mention the change.
* spot/twaalgos/sccinfo.cc, spot/twaalgos/sccinfo.hh: Make sure
scc_and_mark_filter does not install a filter if there is nothing
to filter.
* tests/python/genem.py, spot/twaalgos/genem.cc,
python/spot/impl.i: Adjust.
* spot/twaalgos/sccinfo.hh, python/spot/impl.i: Here. This avoid
ambiguities where options (integer in Python) are interpreted as
initial states.
* tests/python/genem.py: Adjust.
* spot/twaalgos/simulation.cc: Restrict common_in marks to current SCC
when pushing them, otherwise weak automata might become inherently
weak.
* tests/core/sim3.test: Add test case.
* spot/twaalgos/dot.cc: Implement support for hidding labels.
* tests/core/readsave.test: Test it.
* bin/common_aoutput.cc: Add --help text.
* NEWS: Mention it.
* spot/twaalgos/sccinfo.hh, spot/twaalgos/sccinfo.cc: Here.
* spot/twaalgos/genem.cc: Use it.
* python/spot/impl.i, python/spot/__init__.py: Add bindings.
* tests/python/genem.py: Test it.
* NEWS: Mention it.
* spot/twa/acc.hh, spot/twa/acc.cc: Implement the new methods.
* python/spot/impl.i: Add bindings for vectors of acc_cond.
* tests/python/acc_cond.ipynb: Test the two methods.
* NEWS: Adjust.
* tests/python/genem.py: Use SPOT_ON_ACC explicitely.
* spot/twaalgos/genem.cc: Do not keep track of states. Don't
check that the clauses of the disjuncts are Fin-less: they aren't
(this was discovered while discussing with Jan and Fanda).
Related to issue #376.
* spot/kripke/kripkegraph.hh: Avoid indirect type definitions for the
benefit of Swig.
* python/spot/impl.i: Add bindings for iterators over kripke_graph
states and edges.
* tests/python/kripke.py: New file.
* tests/Makefile.am: Add it.
* NEWS: Update.
Suggested by František Blahoudek.
* spot/twaalgos/simulation.cc: When doing forward simulation with
state-based acceptance as input but transition-based acceptance as
output, pull acceptance marks on incoming edges instead of pushing
them to outgoing edges.
* tests/core/dra2dba.test, tests/core/exclusive-tgba.test,
tests/core/ltlcrossce.test, tests/core/satmin3.test,
tests/core/sim3.test, tests/python/satmin.ipynb: Adjust test cases.
