* bin/common_post.cc, bin/randaut.cc: Implement -b/--buchi.
Also add --sba as alias for -B, and --gba as alias for --tgba.
* NEWS: Document those changes.
* doc/org/ltl2tgba.org, doc/org/oaut.org: Adjust documentation.
* tests/core/ltl2tgba2.test, tests/core/ltlcross2.test,
tests/core/randaut.test: Add more tests.
* tests/core/sbacc.test: --sbacc cannot be abbreviated as --sba
anymore.
Mentioned in issue #298.
* spot/twaalgos/determinize.cc: Do not copy prop_complete of
the input if it is false.
* tests/python/298.py: Test it.
* NEWS: Mention the bug.
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.
This helped confirming a behavior observed in #298.
* spot/twaalgos/translate.cc, spot/twaalgos/translate.hh: Add support
for -x exprop.
* bin/spot-x.cc, NEWS: Document it.
* tests/core/ltl2tgba2.test: Test it.
* spot/twaalgos/game.hh, spot/twaalgos/game.cc: Rename
solve_reachability_game() as solve_safety_game(), rewrite it (the old
implementation incorrectly marked dead states as winning for their
owner).
* tests/python/paritygame.ipynb: Rename as...
* tests/python/games.ipynb: ... this, and illustrate
solve_safety_game().
* tests/Makefile.am, NEWS, doc/org/tut.org: Adjust.
* tests/python/except.py: Add more tests.
Part of #444.
* spot/twaalgos/minimize.cc (minimize_wdba): Terminal automata do not
need a product to decide which states are accepting in the DBA. This
is faster, and also determinize more formulas of #443.
* tests/core/ltl2tgba2.test: Adjust the expected iteration where
determinization will be aborted.
Part of #444.
* spot/twaalgos/powerset.cc, spot/twaalgos/powerset.hh: Implement
accepting sink handling.
* spot/twaalgos/minimize.cc (minimize_wdba): Pass sinks to
tgba_powerset.
* spot/misc/bitvect.hh: Add an interesects method.
* tests/core/ltl2tgba2.test: More tests.
* NEWS: Mention this new feature.
Fixes#443, reported by Roei Nahum. (However the fix
only works for the development version, where wdba-det-max
was introduced to work around that kind of problem.)
* spot/twaalgos/minimize.cc: Avoid aborter being implicitly
converted to Boolean.
* tests/core/ltl2tgba2.test: Add test case.
* THANKS: Add Roei Nahum.
This fixes#442.
* spot/twaalgos/simulation.cc (iterated_simulations_): Initialize next
so that we can exit after the first iteration if no change was made.
* NEWS: Mention the bug.
This fixes#441, reported by Jérôme Dubois.
* tests/python/mergedge.py: New file.
* tests/Makefile.am: Add it.
* spot/twa/twagraph.cc (merge_edges): Fix initialization of second
loop.
* NEWS: Mention the bug.
* doc/org/satmin.tex: Use a plain background color instead of some
hashed lines pattern. This reduces the size of the resulting SVG
file from 1.9MB to 50kB after minification.
* doc/org/satmin.org: Adjust to mention autfilt.
