Provide a way to output automata with state-based acceptance. Also
print the guards using to_lbt_string() for consistency: as a
consequence, atomic proposition that do not match p[0-9]+ are now
double-quoted.
* src/tgbaalgos/lbtt.hh (lbtt_reachable): Add a sba option.
* src/tgbaalgos/lbtt.cc: Implement it, and use to_lbt_string().
* src/ltlvisit/lbt.cc (is_pnum): Reject 'p' without number.
* src/bin/ltl2tgba.cc: Activate the sba option of --ba was given.
Add an option --lbtt=t to get the old behavior.
* src/bin/man/ltl2tgba.x: Document the LBTT format we use with
some links and examples.
* src/tgbatest/lbttparse.test: More tests.
* src/tgbatest/ltlcross2.test: Add a check with --lbtt --ba.
* NEWS: Update.
* wrap/python/ajax/ltl2tgba.html: Augment and update tooltips to match
vocabulary in the Spin'13 paper. Hide the compose obligation option
since it's a work in progress.
* src/bin/ltlcross.cc: Implement the counters.
* doc/org/ltlcross.org: Update the documentation.
* bench/ltl2tgba/sum.py: Do not assume a fixed column for the time.
* NEWS: Update.
* src/tgbaalgos/isweakscc.cc, src/tgbaalgos/isweakscc.hh: Do not pass
automata since they are known from the scc. Avoid several dynamic
casts. Try to match the established vocabulary wrt "weak" and
"inherently weak". The old is_weak_scc() that used to enumerate cycles
is therefore renamed to is_inherently_weak_scc(), while the new
is_weak_scc() will should ensure all transitions are fully accepting.
* NEWS: Mention the new interface.
Provides 3 heurisitics to compute the strength of an SCC:
inherent, structural and syntactic
* src/tgbaalgos/isweakscc.cc: implementation
* src/tgbaalgos/isweakscc.hh: definition
The set of rules enabled by favor_even_univ try to "lift" the
subformulae that are both eventual and universal, so they appear
higher in the AST. This is contrary to what we used to do (and still
do when the option is unset), were we try to postpone such subformulae
(by moving them down the AST). It is still a bit experimental.
* src/ltlvisit/simplify.hh: Add option favor_event_univ.
* src/ltlvisit/simplify.cc: Implement new rewriting rules.
* doc/tl/tl.tex: Document them.
* src/tgbatest/ltl2tgba.cc: Add option -ra to enable them.

to enable the new rules.
* src/ltltest/eventuniv.test: New file to test them.
* src/ltltest/Makefile.am: Add it.
This has to be turned on using "-x comp-susp" and other
related options documented in spot-x (7).
* src/tgbaalgos/translate.hh, src/tgbaalgos/translate.cc:
Add support for calling composition-suspension, with
optional simulation, WDBA-minimization, and composition.
* src/bin/spot-x.cc: Document the new options.
* src/bin/man/spot-x.x: Add some bibliography.
* src/tgbatest/ltlcross2.test: Test it.
* src/tgbaalgos/sccfilter.cc: Reuse existing acceptance set as filler
in SCC sets that need less SCC sets than the other SCCs automaton.
* src/tgbatest/sccsimpl.test: Add more tests.
* src/tgbaalgos/postproc.cc, src/tgbaalgos/postproc.hh: Do simulation
on the BA produced in --high mode.
* src/bin/spot-x.cc: Document the ba-simul option that can be used
to disable it.
We used to set PATH in emacs, but because babel executes "sh" via
shell-command, the configuration of the main shell may supersedes ours.

doc/org/ltlfilt.org, doc/org/randltl.org, doc/org/tools.org,
doc/org/genltl.org: Move all local-file variable to...
* doc/org/.dir-locals.el: ... here. And also set the PATH
in org-babel-sh-command.
* doc/org/init.el.in: Set the PATH in org-babel-sh-command.
* src/bin/ltlfilt.cc: Add options --remove-x and --stutter-invariant.
* src/ltlvisit/remove_x.cc, src/ltlvisit/remove_x.hh: New files.
* src/ltlvisit/Makefile.am: Add them.
* src/ltltest/remove_x.test: New file.
* src/ltltest/Makefile.am: Add it.
* NEWS: Mention the new algorithms.
This is one less useless dependency on Boost.
* src/ltlparse/ltlscan.ll: Replace lexical_cast<unsigned>() by
strtoul().
* src/ltltest/parseerr.test: Add a test case.
* doc/org/init.el.in, doc/org/syntax.css: New files.
* configure.ac: Generate init.el from init.el.in, and check for
emacs.
* doc/Makefile.am: Build userdoc/ from org/ and distribute userdoc/.
* README: Mention org/ and userdoc/.
* doc/org/ioltl.org: Mention ltl2dstar and the changes to the prefix
parser.
* doc/org/ltlcross.org: Mention bench/ltl2tgba/sum.py.
* doc/org/tools.org: Bump version number.
This perform pre- and post-processings in addition to
the LTL-to-TGBA translation.
* src/tgbaalgos/translate.cc, src/tgbaalgos/translate.hh: New files.
* src/tgbaalgos/Makefile.am: Add them.
* src/tgbaalgos/postproc.hh: Make the private part protected, so
that we can inherit from that in the translator class.
* src/bin/ltl2tgba.cc: Use the translator class to hide LTL
simplification, translation, and postprocessings.

* src/bin/Makefile.am, src/bin/man/Makefile.am: Adjust.
* src/bin/man/ltl2tgba.x: Remove all fine-tuning options,
and make a reference spot spot-x (7).
* src/bin/common_setup.hh, src/bin/common_setup.cc: Add
a misc_argp_hidden version of the option, so that --help
and --version are not shown in the --help output used
by help2man to generate spot-x.7.
* src/bin/ltl2tgba.cc: Refer to spot-x.7.
