instructions.
New in spot 2.0.1 (2016-05-09)
Library:
* twa::unregister_ap() and twa_graph::remove_unused_ap() are new
methods introduced to fix some of the bugs listed below.
Documentation:
* Add missing documentation for the option string passed to
spot::make_emptiness_check_instantiator().
* There is now a spot(7) man page listing all installed
command-line tools.
Python:
* The tgba_determinize() function is now accessible in Python.
Bug fixes:
* The automaton parser would choke on comments like /******/.
* check_strength() should also set negated properties.
* Fix autfilt to apply --simplify-exclusive-ap only after
the simplifications of (--small/--deterministic) have
been performed.
* The automaton parser did not fully register atomic propositions
for automata read from never claim or as LBTT.
* spot::ltsmin::kripke() had the same issue.
* The sub_stats_reachable() function used to count the number
of transitions based on the number of atomic propositions
actually *used* by the automaton instead of using the number
of AP declared.
* print_hoa() will now output all the atomic propositions that have
been registered, not only those that are used in the automaton.
(Note that it will also throw an exception if the automaton uses
an unregistered AP; this is how some of the above bugs were
found.)
* For Small or Deterministic preference, the postprocessor
will now unregister atomic propositions that are no longer
used in labels. Simplification of exclusive properties
and remove_ap::strip() will do similarly.
* bench/ltl2tgba/ was not working since the source code
reorganization of 1.99.7.
* Various typos and minor documentation fixes.
