spot/src/tgba/tgbaexplicit.hh
Alexandre Duret-Lutz 2b9f17202c This implements Couvreur's FM'99 ltl2tgba translation.
* src/tgba/bdddict.cc (bdd_dict::is_registered): Split as ...
(bdd_dict::is_registered_proposition, bdd_dict::is_registered_state,
bdd_dict::is_registered_accepting_variable): ... these.
* src/tgba/bdddict.hh: Likewise.
* src/tgba/tgbaexplicit.cc (tgba_explicit::set_init_state): New method.
(tgba_explicit::declare_accepting_condition): Arrange so that this
function can be called during the construction of the automaton.
(tgba_explicit::complement_all_accepting_conditions): New method.
(tgba_explicit::has_accepting_condition): Adjust to call
bdd_dict::is_registered_accepting_variable.
* src/tgba/tgbaexplicit.hh (tgba_explicit::set_init_state,
tgba_explicit::complement_all_accepting_conditions): New methods.
* src/tgbaalgos/ltl2tgba_fm.cc, src/tgbaalgos/ltl2tgba_fm.hh:
New files.
* src/tgbaalgos/Makefile.am (tgbaalgos_HEADERS,
libtgbaalgos_la_SOURCES): Add them.
* src/tgbaalgos/ltl2tgba.hh: Add bibtex entry in comment.
* src/tgbatest/Makefile.am (check_PROGRAMS): Remove spotlbtt
and tbalbtt.
(tbalbtt_SOURCES, tbalbtt_CXXFLAGS, spotlbtt_SOURCES): Remove.
* src/tgbatest/spotlbtt.cc: Delete, superseded by "ltl2tgba -F -t".
* src/tgbatest/ltl2tgba.cc: Implement the -f and -F options.
* src/tgbatest/spotlbtt.test: Use "ltl2tgba -F -t" instead of
"spotlbtt", "ltl2tgba -F -t -D" instead of "tbalbtt", and add
also check the ltl2tgba_fm translator.
* wrap/python/spot.i: Wrap ltl2tgba_fm.
* wrap/python/cgi/ltl2tgba.in: Add radio buttons to select
between ltl2tgba and ltl2tgba_fm.
* wrap/python/tests/ltl2tgba.py: Add support for the -f option.
* wrap/python/tests/ltl2tgba.test: Try the -f option.
