Fixes#233, although more cleanup would be welcome.
* spot/twaalgos/minimize.cc: Replace the uses of twa methods by
twa_graph methods, and simplify some data structures.
* tests/core/acc_word.test, tests/core/readsave.test,
tests/python/automata.ipynb: Adjust changed output due
to different data structures.
If no input have been specified, and the standard input is not a tty all
tools now default to reading it. If standard input is a tty, all tools
display an error message. Additionally, - is now a shorthand for -F- in
all tools.
* NEWS: Summarize this.
* bin/common_finput.cc, bin/common_finput.hh (check_no_formulas,
check_no_automaton): New functions that implement the above istty()
logic.
* bin/autfilt.cc, bin/dstar2tgba.cc, bin/ltl2tgba.cc, bin/ltl2tgta.cc,
bin/ltlcross.cc, bin/ltldo.cc, bin/ltlgrind.cc: Use these function,
and recognize '-' if it was not the case.
* tests/core/acc_word.test, tests/core/ltldo.test,
tests/core/minusx.test, tests/core/readsave.test,
tests/core/unambig.test: Adjust some tests to exercise this.
* doc/org/autfilt.org, doc/org/csv.org, doc/org/dstar2tgba.org,
doc/org/ltl2tgba.org, doc/org/ltlcross.org, doc/org/ltlfilt.org,
doc/org/oaut.org: Adjust the documentation and simplify some
examples.
* bin/autfilt.cc: Add the option.
* NEWS: Mention it.
* tests/core/acc_word.test: Test it.
* spot/twaalgos/emptiness.cc,
spot/twaalgos/emptiness.hh (twa_run::project): New method.
* bin/common_range.hh: Store the common definition of words.
* bin/autfilt.cc: Use it.
* bin/ltlfilt.cc: Likewise, and implement those two options.
* tests/core/acc_word.test: Test them.
* doc/org/autfilt.org: Augment the last example to point out
that it can now be done with ltlfilt.
* NEWS: Mention the new options.
* bin/autfilt.cc: Translate each word as an automaton once,
and do not make a global product of all of them.
* spot/twaalgos/word.cc: Register the atomic propositions used by the
word when converting it into an automaton.
* tests/core/acc_word.test: Add a test case that used to fail, and
another test that make sure some words are not accepted.
Suggested by Matthias Heizmann. Fixes#109.
* NEWS: notify the new option
* THANKS: add Matthias Heizmann
* bin/autfilt.cc: add new option --accept-word=WORD which filters
automata that accept WORD
* doc/org/autfilt.org: add an example of the new option
* tests/Makefile.am: add core/acc_word.test to the list of test files
* tests/core/acc_word.test: test some uses of the new option
