Fixes#56.
* src/bin/common_aoutput.cc, src/bin/common_aoutput.hh,
src/bin/dstar2tgba.cc: Implement it.
* src/bin/autfilt.cc, src/bin/ltl2tgba.cc, src/bin/ltldo.cc,
src/bin/randaut.cc: Fix main() to catch exceptions from the
constructor of the automaton printer as well.
* src/tgbatest/randaut.test: Add a test case.
* doc/org/oaut.org: Document it.
* src/bin/autfilt.cc: Add option --intersect. Factor the code to read
automata.
* src/tgbatest/neverclaimread.test: Rewrite the tests, replacing 3 calls
to ltl2tgba by a single call to autfilt.
Combined with 87c2b29, this fixes#7.
* src/tgbaalgos/stutterize.cc: Call keep_props().
* src/tgbaalgos/closure.cc: Just specify the encoding.
* src/bin/autfilt.cc: Add a --instut=2 option.
* src/tgbatest/stutter.test: More test.
* src/bin/common_aoutput.hh, src/bin/common_aoutput.cc: Adjust to
support three kind of statistics printer, depending on whether the
tool input formulas, automata, or nothing.
* src/bin/randaut.cc, src/bin/autfilt.cc: Adjust.
* src/bin/ltl2tgba.cc: Use the common_aoutput printers. The
--csv-escape option disappeared along the way, but it was not honored
anyway...
* src/bin/autfilt.cc: Also accept '-u' for '--uniq'.
* src/bin/randaut.cc: Likewise, plus fix the unicity check.
* src/tgbatest/uniq.test: Really test it.
* src/tgbaalgos/dotty.cc, src/tgbaalgos/dotty.hh: Add an options
parameter.
* src/bin/randaut.cc, src/bin/autfilt.cc, src/bin/dstar2tgba.cc,
src/bin/ltl2tgba.cc, wrap/python/ajax/spot.in: Use it.
* src/tgbatest/det.test, src/tgbatest/dstar.test,
src/tgbatest/ltl2tgba.cc, src/tgbatest/monitor.test,
src/tgbatest/neverclaimread.test, src/tgbatest/tgbaread.test,
src/graphtest/tgbagraph.test: Adjust
because automata are now output horizontally.
* NEWS: Mention the change.
* src/bin/autfilt.cc: Use isomorphism_checker.
* src/tgbaalgos/are_isomorphic.cc, src/tgbaalgos/are_isomorphic.hh: Wrap
are_isomorphic inside a class to keep the canonic version of the first
automaton between two calls, and use a more efficient algorithm in case
both automata are deterministic.
* src/tgbatest/isomorph.test: Add tests for deterministic automata.
* src/tgbaalgos/are_isomorphic.cc, src/tgbaalgos/are_isomorphic.hh,
src/bin/autfilt.cc: are_isomorphic now uses canonicalize. It returns a
bool, because the mapping cannot be deduced easily from the
canonicalized automaton.
* src/graph/graph.hh: Add equality operator to trans_storage_t
for easy comparison of transition vectors.
* src/tgba/tgbagraph.hh: Add equality operator to tgba_graph_trans_data
and to tgba_digraph.
* src/tgbaalgos/canonicalize.cc, src/tgbaalgos/canonicalize.hh:
New files.
* src/tgbaalgos/Makefile.am: Add them.
* src/tgbatest/isomorph.test: Test them.
* src/bin/autfilt.cc: Add these new options.
* src/tgbaalgos/stutterize.cc, src/tgbaalgos/stutterize.hh: Make it
possible to call sl() and sl2() without passing the set of atomic
propositions.
* src/tgbatest/stutter.test: New file.
* src/tgbatest/Makefile.am: Add it.
* src/tgba/tgbagraph.cc (merge_transition): Do it.
* src/tgbatest/readsave.test: Test it.
* src/bin/autfilt.cc: Fix statistics about the original
automaton when using --stats or --name.
* src/bin/autfilt.cc: Do not use -I for --are-isomorphic.
Fix --help.
* src/tgbatest/isomorph.test: Adjust to use --are-isomorphic, and speed
it up 5-fold.
* src/bin/autfilt.cc: Return with exit code 1 if no match found.
* src/tgbaalgos/are_isomorphic.cc,src/tgbatest/degenlskip.test
src/tgbatest/explpro2.test,src/tgbatest/explpro3.test
src/tgbatest/explpro4.test,src/tgbatest/explprod.test
src/tgbatest/neverclaimread.test, src/tgbatest/readsave.test
src/tgbatest/tripprod.test: Use exit status to check for output
emptiness instead of 'test -n'.
* src/tgbatest/isomorph.test: Simplify test.
And add the corresponding --isomorphic=FILENAME option to autfilt.
* src/tgbaalgos/are_isomorphic.cc, src/tgbaalgos/are_isomorphic.hh:
New.
* src/tgbaalgos/Makefile.am: Add it.
* src/bin/autfilt.cc: Add --isomorphic option.
* src/tgbatest/isomorph.test: Test it.
* src/tgbatest/Makefile.am: Add it.
* src/hoaparse/parsedecl.hh (hoa_abort): New structure.
* src/hoaparse/hoascan.ll: Throw hoa_abort on --ABORT--.
* src/hoaparse/hoaparse.yy: Deal with this exception.
* src/hoaparse/public.hh: Add a boolean flag to mark aborted automata.
* src/bin/autfilt.cc: Report aborted automata.
* src/tgbatest/hoaparse.test: Add test case.
* src/hoaparse/hoaparse.yy: Improve error recovery,
and fix location tracking in streams.
* src/hoaparse/public.hh: Store the last location so
that the next parse start at the correct position.
* src/bin/autfilt.cc: Stop parsing a stream on irrecoverable errors.
* src/tgbatest/hoaparse.test: Adjust tests.
