      Fix interpretation of {e[*]} and !{e[*]}. · cb7bdf8c
      Alexandre Duret-Lutz authored
      This follows from a discussion with Ernesto Posse.
      
      The semantics for the {...} operator we use in Spot comes from the
      cl(...) operator defined by Dax et al. (ATVA'09).  This is slightly
      different from the the way the PSL spec interprets a SERE used in the
      context of a temporal formula (appendix B.3.1.1.2, item 7).
      
      cl({a;b}[*]) would match any infinite word that starts with a;b, while
      in PSL {a;b}[*] would match any infinite word that alternates a and b.
      
      Spot documents that {SERE} in a temporal formula is interpreted like
      cl(SERE) however it failed to ignore the empty prefix of SERE.  So
      {{a;b}[*]} would match anything, because the empty word is a prefix of
      any word, and is also accepted by {a;b}[*].  Some trivial identities
      and basic rewritings were also wrongly considering these empty
      prefixes as well.
      
      This patch therefore fixes the translation and syntactic
      simplification rules, to really ignore these empty prefixes.
      
      In some future version it should probably be wise to rename this {...}
      operator as cl(...), and use {...} for the semantics given in appendix
      B.3.1.1.2 (item 7) of the PSL specs.
      
      * src/ltlast/unop.cc: Fix trivial identities.  We have
      {[*0]} = 0 and !{[*0]} = 1.
      * src/ltlvisit/simplify.cc: Fix basic rewriting rules.
      {e[*]} = {e} and !{e[*]} = !{e}.
      * doc/tl/tl.tex: Adjust documentation.
      * doc/tl/tl.bib (dax.09.atva): New entry.
      * src/tgbaalgos/ltl2tgba_fm.cc: Do not accept any
      infinite word for {e[*]} just because the empty
      prefix is matched by e[*].
      * src/tgbatest/ltl2tgba.test: Add a test case.
      * NEWS: Mention it.
      * THANKS: Add Ernesto.

      Introduce scc_filter_states(). · 6b5b002f
      Alexandre Duret-Lutz authored
      The main motivation is the upcoming patch that introduces
      simulation_sba() and requires this function.
      
      * src/tgbaalgos/sccfilter.hh, src/tgbaalgos/sccfilter.cc: Implement it.
      * src/tgbaalgos/postproc.cc: Use it for monitors, because we do not
      care about acceptance conditions.
      * NEWS: Mention it.

      lbtt: improve the LBTT output · eed7e2df
      Alexandre Duret-Lutz authored
      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.

      isweakscc: cleanup interfaces and code · cb7cd868
      Alexandre Duret-Lutz authored
      * 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.
