* src/tgba/tgbaexplicit.hh (num_states): New method.
* src/tgbaalgos/minimize.hh, src/tgbaalgos/minimize.cc
(minimize_obligation): Add a reject_bigger option.
* src/tgbatest/ltl2tgba.cc (-RM): New option.
* src/tgbatest/spotlbtt.test: Test -RM.
* bench/ltl2tgba/algorithms: Include -RM in addition to -Rm, and
replace -RDS by -RIS.
* NEWS: Mention this.
* src/ltlparse/ltlparse.yy: Keep the left operand of binary operator,
if the right one is erroneous. Also keep the sane beginning of
parenthesized blocks.
* src/ltltest/parseerr.test: Adjust test cases.
* NEWS: Mention it.
The previous implementation was fine to catch timeout of third-party
tools (like dot), but to good to catch timeout in Spot itself, because
Python will not deliver a SIGALRM while a native function (e.g. Spot's
translation) is running. So we fork() the Python process, with a
parent that does nothing but wait for the termination of the child or
for an alarm. On SIGALRM, the parent kills all children.
* wrap/python/ajax/spot.in: Adjust to fork.
* wrap/python/tests/alarm.py: New test file to test this
scenario in a more controled environment.
* wrap/python/tests/Makefile.am: Add it.
We need a marked version of !{r} to perform breakpoint unroling.
* src/ltlast/unop.cc, src/ltlast/unop.hh: Declare a NegClosureMarked
operator.
* src/ltlvisit/mark.hh, src/ltlvisit/mark.cc,
src/tgbaalgos/ltl2tgba_fm.cc: Adjust to deal with NegClosureMarked
and NegClosure as apropriate.
* src/ltlvisit/simplify.cc, src/ltlvisit/tostring.cc,
src/ltlvisit/tunabbrev.cc, src/tgbaalgos/eltl2tgba_lacim.cc,
src/tgbaalgos/ltl2taa.cc, src/tgbaalgos/ltl2tgba_lacim.cc,
src/tgba/formula2bdd.cc: Deal with NegClosureMarked in the same way as
we deal with NegClosure.
* src/tgbatest/ltl2tgba.test: More tests.
* src/ltltest/kind.test: Adjust.
* doc/tl/tl.tex: Mention the marked negated closure.
* src/ltlvisit/wmunabbrev.hh, src/ltlvisit/wmunabbrev.cc: New files.
* src/ltlvisit/Makefile.am: Add them.
* src/ltlvisit/tostring.cc (to_spin_string): Use the new rewriting.
* wrap/python/ajax/spot.in: Warn when a "Spin" still contain PSL
operators.
* wrap/python/ajax/ltl2tgba.html: Adjust help text.
* doc/tl/tl.tex, NEWS: Document the new rewriting.
* src/ltlparse/ltlparse.yy: Make all the above operators
right-associative. Also let `:' have precedence over `;'.
* src/ltltest/reduccmp.test: Adjust for the `:' precedence.
* doc/tl/tl.tex, NEWS: Document this.
* wrap/python/ajax/js/jquery.ba-bbq.min.js: New file.
* wrap/python/ajax/Makefile.am: Distribute it.
* wrap/python/ajax/ltl2tgba.html: Include it, and
Adjust the code to update the URL's hash fragment,
and to read it.
* configure.ac: Add a --disable-python option tied to
a USE_PYTHON conditional.
* README: Document the option.
* wrap/Makefile.am: Use the conditional.
* src/tgbaalgos/minimize.cc (minimize_wdba): Fix the Löding
algorithm to use colors. The previous implementation was an
incorrect approximation.
* src/tgbatest/wdba2.test: New file showing two equivalent
formulas that were minimized in automata with different sizes.
* src/tgbatest/Makefile.am: Add it.
* src/tgbaalgos/minimize.cc (minimize_dfa): Fix detection of the
last iteration. An extra iteration case could be missed in case
where a split generates only singletons, and yet predecessor
classes need to be refined.
* src/ltlvisit/length.cc: Fix computation for ltl::multop
operator. "a&b&c" was reported with length 3, ignoring the
"&" operators, because of a typo.
* src/ltlvisit/length.hh: Fix description to correctly
reflect this change intended since 2010-01-22.
* src/ltltest/length.test, src/ltltest/length.cc: New files.
* src/ltltest/Makefile.am: Add them.
