Fixes#497.
* spot/twaalgos/dot.cc: Implement this option.
* tests/core/ltl2tgba.test, tests/core/randaut.test: @ is
now a valid option for --dot, use something else.
* tests/python/aliases.ipynb: New file.
* tests/Makefile.am, doc/org/tut.org: Add it.
* doc/org/hoa.org: Mention aliases.
* NEWS: Mention this new feature.
Reported by František Blahoudek.
* spot/twaalgos/postproc.cc: Turn "t" into "Inf(0)" for BA.
* tests/core/ltl2tgba.test: Add test case.
* NEWS: Mention the bug.
This is long overdue, and we probably want to use tls-impl=1 in
ltlsynt.
* spot/twaalgos/translate.cc, spot/twaalgos/translate.hh:
Add support for tls-impl=N.
* tests/core/ltl2tgba.test: Test it.
* bin/spot-x.cc, NEWS: Document it.
Fixes#286.
* spot/twaalgos/simulation.cc: Only set the deterministic
property, not the non-deterministic one.
* tests/core/ltl2tgba.test: Add test case.
* NEWS: Mention the issue.
Fixes#277.
* spot/twaalgos/ltl2tgba_fm.cc: Improve the translation of f U g
when f is universal. Suggested by Maximilien Colange.
* tests/core/ltl2tgba.test: Test it.
Fixes#262 again. Reported by Maximilien Colange.
* spot/twaalgos/simulation.cc: Use state numbers to order classes, not
their signatures. The problem was that even if two simulation of the
same automaton assign the same signature, the BDD identifier used for
that signature might be different, and therefore the ordering obtained
by using BDDs as keys in a map can be different. A side-effect of
this change is that the order of states in automata produced by
simulation-based reduction may change; many tests had to be updated.
* tests/core/ltl2tgba.test: Add a new test case based on Maximilien's
report.
* tests/core/complement.test, tests/core/det.test,
tests/core/parseaut.test, tests/core/prodor.test, tests/core/scc.test,
tests/python/atva16-fig2a.ipynb, tests/python/automata.ipynb,
tests/python/decompose.ipynb, tests/python/decompose_scc.py,
tests/python/highlighting.ipynb, tests/python/piperead.ipynb,
tests/python/sccinfo.py, tests/python/simstate.py,
tests/python/testingaut.ipynb, tests/python/word.ipynb: Update
test case for new order of states.
Fixes#262, reported by Maximilien Colange.
* bin/common_output.cc, bin/common_aoutput.cc, bin/common_aoutput.hh:
Clear the set of atomic propositions if --stats=%[...]x was used.
* spot/twa/bdddict.cc: Release any formula associated to a BDD when it
is unregistered, do not wait for the dictionary's destruction. This
was the main culprit for #262.
* tests/core/ltl2tgba.test: Add test cases.
* NEWS: Mention the bug.
The cache used in formula simplification will keep atomic propositions
defined between several translations, and may impact variable order.
Reported by Maximilien Colange.
* spot/tl/simplify.hh, spot/tl/simplify.cc,
spot/twaalgos/translate.cc, spot/twaalgos/translate.hh (clear_cache):
New method.
* bin/ltl2tgba.cc, bin/ltl2tgta.cc: Call it.
* spot/twaalgos/stats.cc: Do not keep a point to the formula after
printing statistics.
* tests/core/ltl2tgba.test: Add a test case.
* tests/core/readsave.test: Adjust one formula.
* NEWS: Mention the issue.
Fixing this bug alone revealed another bug: parsing never claim or LBTT
automata did not register APs. So this fixes both bugs.
This is the first part of #170.
* spot/twa/twa.hh (register_aps_from_dict): New method.
* spot/parseaut/parseaut.yy: Call it for never claim and LBTT files.
* spot/twaalgos/stats.cc: Simplify using ap_vars().
* tests/core/ltl2tgba.test: Add a test case.
* NEWS: Mention the bugs.
* bin/common_aoutput.hh, bin/common_aoutput.cc,
bin/ltl2tgba.cc, bin/ltldo.cc: Add support for %< and %>.
* tests/core/ltl2tgba.test, tests/core/ltldo.test: Test it.
* NEWS: Mention it.
