doc/org/tut22.org, doc/org/tut30.org, doc/org/upgrade2.org: Here.
* doc/org/index.org: Also add keywords in case it is useful, and
use a more descripting title for search engines.
* spot/twaalgos/strength.cc, spot/twaalgos/strength.hh
(is_inherently_weak_automaton): New function.
(is_type_automaton): Adjust to implement the above and
set prop_inherently_weak().
* spot/twaalgos/isweakscc.cc, spot/twaalgos/isweakscc.hh:
Rewrite is_inherently_weak_scc() to not enumerate cycles.
* spot/bin/autfilt.cc: Add a --is-inherently-weak option.
* spot/tests/readsave.test: More tests.
* spot/tests/strength.test: Adjust expected output.
* doc/org/hoa.org: Adjust documentation of --check.
* NEWS: Mention those changes.
* src/twaalgos/hoa.cc, src/twaalgos/hoa.hh: Implement it.
* NEWS, doc/org/hoa.org, src/bin/common_aoutput.cc: Document it.
* src/tests/readsave.test: Test it.
* elisp/hoa-mode.el, elisp/Makefile.am, elisp/README: New files.
* debian/copyright, configure.ac, README, Makefile.am: Adjust.
* doc/org/init.el.in: Adjust to load hoa-mode.el.
* doc/org/spot.css: Add entries for HOA mode.
* doc/org/hoa.org, doc/org/ltldo.org, doc/org/oaut.org,
doc/org/tut20.org, doc/org/tut21.org, doc/org/tut22.org,
doc/org/tut30.org: Make the HOA outputs as HOA.
* src/twa/twa.hh: Store the terminal property.
* src/twaalgos/hoa.cc, src/parseaut/parseaut.yy: Add I/O for "terminal".
* src/twaalgos/ltl2tgba_fm.cc, src/twaalgos/minimize.cc: Set terminal
as apropriate.
* src/twaalgos/safety.cc: Use it.
* doc/org/tut21.org, doc/org/hoa.org, NEWS: Document it.
* src/tests/complement.test, src/tests/monitor.test,
wrap/python/tests/automata-io.ipynb: Adjust.
* src/twaalgos/hoa.cc: Output do not output "unambiguous" if the
automaton is deterministic. Add option "v" to cancel this restriction,
and also output "no-univ-branch".
* src/twaalgos/hoa.hh: Document the "v" option.
* src/tests/readsave.test: Test it.
* src/tests/unambig.test: Adjust for unambiguous not being output
if the automaton is deterministic.
* src/bin/common_aoutput.cc, NEWS: Document it.
* doc/org/hoa.org: Add a summary table about how properties are handled.
* src/twa/twa.hh (prop_deterministic): Setting this should also
set the unambiguous property.
* src/twaalgos/isunamb.cc: Simplify the property check.
I have to remember that org-mode does not evaluate something unless it
is eventually exported.
* doc/org/hoa.org, doc/org/ioltl.org, doc/org/tut21.org,
doc/org/tut30.org: Adjust exports commands.
* doc/org/autfilt.org, doc/org/dstar2tgba.org, doc/org/hoa.org,
doc/org/ltlcross.org: Fix several typos. In particular ":results" and
":exports" both end with s.
