Fix an issue reported by Tomáš Babiak, who noticed that he could not
manage to have ltl2tgba process `genltl --go-theta=N` efficiently for
larger values of N.
* spot/twaalgos/translate.hh (set_level): Reset any owned LTL simplifier
whenever the optimization level is changed.
* NEWS: Mention the bug.
Related to #188. This is a third fix that independently
makes `'utfilt --is-unambiguous -q smaller.hoa' instantaneous.
* spot/twaalgos/remfin.cc: Clean the received automaton if
necessary.
* bin/autfilt.cc: No need to call cleanup_acceptance_here() before
remove_fin() anymore.
* tests/core/remfin.test: Add an additional test.
* NEWS: Mention the change.
As observed in #188, the smaller.hoa automaton is made only of
1-state/1-self-loop SCCs, for which calling remove_fin is a complete
waste of time. This patch alone (i.e., without the other changes
suggested by #188) improves the run time of
% autofilt -q --is-unambiguous smaller.hoa
from 38s to 0.05s.
* spot/twaalgos/sccinfo.cc: If a single-state SCC has undeterminate SCC
and only one self-loop, then it is necessarily rejecting.
* NEWS: Mention the change.
Avoid calling scc_info::determine_unknown_acceptance on the product, as
suggested in #188.
* spot/twaalgos/isunamb.cc (is_unambiguous): Rewrite.
* tests/core/unambig.test: Add the automaton from #188.
* NEWS: Mention the improved function.
* spot/twaalgos/mask.cc,
spot/twaalgos/mask.hh (mask_keep_accessible_states): New function.
Suggested by František Blahoudek.
* bin/ltlcross.cc: Implement the two options.
* doc/org/ltlcross.org, NEWS: Document them.
* tests/core/complementation.test: Adjust test case.
* tests/core/ltlcross3.test, tests/core/unambig.test: More tests.
Report from František Blahoudek.
* bin/ltlcross.cc: Do not display stats for automata
that do not exist.
* tests/core/ltlcross3.test: Test it.
* NEWS: Mention the fix.
* bin/common_cout.cc (check_cout): Force a flush of cout if more than
20ms has elapsed since the last explicit flush.
* bin/common_setup.cc (setup): Untie cin and cout if the input
is not a TTY, so that cout is flush less often.
* NEWS: Mention the change.
Fixes#91.
* bin/autfilt.cc, bin/dstar2tgba.cc: Implement reading CSV files.
* bin/common_finput.cc: Fix comments.
* bin/common_aoutput.cc: Show %<, %> in help text.
* NEWS, doc/org/csv.org: Document it.
* tests/core/readsave.test: Add a short test case.
Reported by Laurent Xu.
* python/spot/impl.i: Fix the iterator to return pointers instead of
references. Because references are ultimately copied.
* tests/python/automata.ipynb: Add test cases.
* NEWS: Mention it.
Part of #38.
* bin/ltlcross.cc: Implement it.
* NEWS: Mention it.
* doc/org/ltlcross.org: Adjust example.
* tests/core/ltlcrossce2.test: New test case.
* doc/org/tut51.org: New file.
* doc/org/tut.org, doc/Makefile.am, NEWS: Add it.
* elisp/ob-dot.el: New file, to work around old org-mode versions.
* elisp/README, elisp/Makefile.am: Add it.
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.
{e[*0..j]}<>->f = {e[*1..j]}<>->f
{e[*0..j]}[]->f = {e[*1..j]}[]->f
Fixes#81.
This required a small change to the bounded-star-normal-form to prevent
infinite recursion.
* spot/tl/simplify.cc: Implement these rules.
* doc/tl/tl.tex, NEWS: Document them.
* tests/core/reduccmp.test: Add tests, and adjust others.
* tests/core/unambig.test: Replace formula that used to generated an
ambiguous automaton, but now generates a deterministic one.
if e is pure eventuality and g => e, then e U g = Fg
if u is purely universal and u => g, then u R g = Gg
Fixes#93.
* doc/tl/tl.tex, NEWS: Document the rules.
* spot/tl/simplify.cc: Implement them.
* tests/core/reduccmp.test: Test them.
* tests/core/det.test: Adjust.
