* spot/twaalgos/translate.cc: When producing Parity output, split LTL
as we do in the Generic case.
* spot/twaalgos/postproc.hh, spot/twaalgos/postproc.cc: Use
acd_transform() and add an "acd" option to disable this.
* bin/spot-x.cc, NEWS: Document this.
* tests/core/genltl.test, tests/core/minusx.test,
tests/core/parity2.test: Adjust test cases for improved outputs.
Based on a mail from Edmond Irani Liu. The test case also serves for
the previous patch.
* bin/genltl.cc, spot/gen/formulas.cc, spot/gen/formulas.hh: Add it.
* NEWS: Mention it.
* tests/core/genltl.test: Test it.
This is motivated by an example sent by Edmond Irani Liu,
that will be tested in next patch.
* spot/twaalgos/dbranch.cc, spot/twaalgos/dbranch.hh: New files.
* python/spot/impl.i, spot/twaalgos/Makefile.am: Add them.
* spot/twaalgos/translate.cc: Call delay_branching_here
unconditionally.
* spot/twa/twagraph.cc (defrag_states): Do not assume
that games are alternating.
* tests/core/genltl.test: Adjust expected numbers.
* tests/python/dbranch.py: New file.
* tests/Makefile.am: Add it.
Because the loops iterate in the opposite order, multiple
test cases need to be adjusted.
* spot/taalgos/tgba2ta.cc, spot/twaalgos/alternation.cc,
spot/twaalgos/dualize.cc, spot/twaalgos/ltl2tgba_fm.cc,
spot/twaalgos/simulation.cc, spot/twaalgos/stutter.cc,
spot/twaalgos/toweak.cc: Replace loops based on
bdd_satonest(x,y,bddtrue) by loops based on minterms_of(x,y).
* tests/core/degenscc.test, tests/core/dualize.test,
tests/core/genltl.test, tests/core/readsave.test,
tests/python/alternation.ipynb, tests/python/automata.ipynb,
tests/python/decompose.ipynb, tests/python/decompose_scc.py,
tests/python/dualize.py, tests/python/sccinfo.py,
tests/python/simstate.py, tests/python/testingaut.ipynb,
tests/python/word.ipynb: Adjust expected test cases. The
only regression is in genltl.test, but the worsened case
should eventually be fixed as discussed in issue #425 anyway.
Related to issue #298.
* spot/twaalgos/determinize.cc: Recognize braces that are temporary
to avoid emitting colors when they become empty.
* tests/python/298.py: New file, showing a reduction of colors.
* tests/Makefile.am: Add it.
* tests/core/ltlsynt.test: Adjust expected output (now smaller).
* tests/core/genltl.test: Adjust one expected output (now larger).
* NEWS: Mention the issue.
Fixes#15.
* spot/twaalgos/minimize.hh, spot/twaalgos/minimize.cc
(minimize_obligation_garanteed_to_work): New function.
* spot/twaalgos/postproc.hh, spot/twaalgos/postproc.cc: Use it if
wdba-minimize=1. Handle new default for wdba-minimize.
* NEWS, bin/spot-x.cc: Document those changes.
* tests/core/ltl2tgba2.test: Add some test cases.
* tests/core/genltl.test: Improve expected results.
* spot/twaalgos/translate.cc: Here.
* NEWS: Mention the change.
* tests/core/genltl.test: Add parity automata sizes for a set of
formulas.
* tests/core/parity2.test: Add another formula to the tests.
* spot/twaalgos/gfguarantee.cc: Rework the history computation to keep
an overapproximation of the history, and a longer one. Also replay
the history even if there is no initial trivial SCC. This helps with
translating FG(!a|XXXb) where we need to keep the history of a, but we
were previously unable to do so because some state had both "a" and
"ab" as input.
* spot/twaalgos/translate.cc: Optimize the product of suspendable
automata by removing useless trivial SCCs.
* tests/core/genltl.test, tests/core/satmin.test, NEWS: Adjust
expected results.
* spot/twaalgos/translate.cc, spot/twaalgos/translate.hh: Build
automata with generic acceptance by doing product of automata for
smaller subformulas.
* bin/spot-x.cc: Mention ltl-split.
* NEWS: Mention the change, and show some results.
* tests/core/genltl.test, tests/python/_product_susp.ipynb,
tests/python/highlighting.ipynb: Adjust test cases.
* doc/org/ltl2tgba.org: Update.
* tests/core/gragsa.test: Add another formula to cover more
code.
Together with the previous patch, this Fixes#353.
Implementing this required to extend our interface two support
two-parameter patterns.
* spot/gen/formulas.cc, spot/gen/formulas.hh: Implement it.
* bin/genltl.cc: Add --sejk-f.
* bin/common_output.cc, bin/common_output.hh: Adjust to handle
"line numbers" that are not integers (e.g., "3,2"), since those
are used to display pattern parameters.
* bin/ltlfilt.cc: Adjust.
* python/spot/gen.i: Add support for two-parameters patterns.
* tests/core/genltl.test, tests/python/gen.ipynb: Augment.
* NEWS: Mention it.
These correspond to the first three blocks of table 1 in S. Sickert,

a "gf-guarantee" option to decide whether to use the new translation.
