* src/tgbatest/ltl2tgba.cc (main): Call scc_filter() before the
degeneralization, because it might remove useless acceptance
conditions. I realized this while looking at experiments from
Rüdiger Ehlers.
* src/saba/sabacomplementtgba.hh (spot): Rewrite Büchi as B\"uchi
is the BibTex entry used as comment, because some version of sed
will choke on non-ascii character and cause sanity/style.test to
fail.
This is actually the third time I fix random_graph(). On
2007-02-06 I changed the function not to generated dead states,
but in a way that made it non-deterministic. On 2010-01-20 I made
the function deterministic again, but it started to generate dead
states as a side effect. This time, I'm making sure that dead
states won't come again with a test-case that we should have had
from the beginning.
* src/tgbaalgos/randomgraph.cc (random_graph): Add an extra
indirection array, state_randomizer[], so that we can reorder
states indices after a random selection without actually changing
the value of the indices used by unreachable_states and
nodes_to_process.
* src/tgbatest/randtgba.test: New file.
* src/tgbatest/Makefile.am: Add randtgba.test.
* wrap/python/cgi-bin/ltl2tgba.in (dot): Use the value computed by
configure.
(os.system): Cleanup stale files only when the form has been
submitted.
(list options): Keep track of the selected value.
(draw_acc_run|print_acc_run): set ec=0 to detect if it has been
later set or not. Fix error message when using generalized
automata with degeneralized emptiness checks.
* wrap/python/cgi-bin/Makefile.am (ltl2tgba.py): Substitute @DOT@.
* wrap/python/cgi-bin/ltl2tgba.in (new): Mark new options as new.
(svg_output, reduce_langcout): Add these new options.
(render_dot): Support svg_output.
* src/sabaalgos/sabareachiter.hh (process_link): Document argument SI.
* src/eltlparse/public.hh (format_parse_errors): Remove the
non-existing eltl_string argument from the description.
(parse_file): Fix name of parameters in documentation.
Doxygen only knows how to call dot with -Tpng, while using
-Tpng:gd produces pictures that are 10 times smaller. Use a
simple wrapper around dot to simplify this.
* doc/dot.in: New file, that wrap the system's dot and replace
-Tpng by -Tpng:gd.
* doc/Makefile.am ($(srcdir)/stamp): Depend on dot.
* doc/Doxyfile.in: Update to 1.6.2.
(DOT_PATH): Set to @srcdir@ to use doc/dot instead of the
system's dot.
* configure.ac: Find the absolute path of dot, and generate
the doc/dot script.
* wrap/python/cgi-bin/ltl2tgba.in: Add options to symbolically
prune unaccepting SCCs in LaCIM, and explicitely pruns unaccepting
SCCs in all algorithms.
* src/tgbaalgos/reductgba_sim.hh: Conceal most of the file to
SWIG.
* wrap/python/spot.i: Include reductgba_sim.hh.
server.
* wrap/python/cgi-bin/ltl2tgba.in: Starts a web server if the
script is not called as a CGI. Arrange to load libraries from
the build directory. Create the spotimg/ if needed when run as
a web server.
* wrap/python/cgi-bin/Makefile.am: Adjust build rule and clean
the spotimg directory.
* wrap/python/cgi-bin/README, NEWS: Update.
* src/tgbaalgos/ltl2tgba_fm.cc, src/tgbaalgos/ltl2tgba_fm.hh:
Remove the containment option.
* src/tgbafromfile.cc, src/tgbafromfile.hh: Remove the
containment_ member.
* src/tgbatest/ltl2tgba.cc (syntax): Remove -c option for
FM algorithm, use it exclusively for TAA.
* src/tgba/tgbacomplement.hh, src/tgba/tgbacomplement.cc: Rename
as...
* src/tgba/tgbakvcomplement.hh, src/tgba/tgbakvcomplement.cc:
... these. It makes more sense since we also have
tgba_safra_complement.
* src/tgba/Makefile.am, src/tgbatest/complement.cc, NEWS: Adjust.
implementation of rational operators in a future version.
* src/ltlparse/ltlscan.ll: Do not recognize "*".
* wrap/python/cgi-bin/ltl2tgba.in: Undocument it.
* NEWS: Mention this.
* src/tgbatest/kv.test, src/tgbatest/ltl2tgba.test,
src/tgbatest/reductgba.test: Replace "*" by "&".
* src/tgbatest/ltl2tgba.cc (syntax, main): Introduce -le to select
this algorithm and -lo to add the default LTL operators. This
replace the undocumented hack to add LTL operators when the
formula with read for command-line, or the automaton was output
for LBTT.
* src/tgbatest/eltl2tgba.test, src/tgbatest/spotlbtt.test: Update
call syntax.
* NEWS: Mention -le, -lo, and -taa.
* src/tgbatest/ltl2tgba.cc (syntax): Move -R3b with the other
LaCIM options.
(main): Speak of "symbolic SCC pruning" instead of "deleting
unaccepting SCC", and do that right after the translation, before
degeneralization. Also error out when -R3b is used on non
symbolic automata.
* src/sanity/readme.test: For each AC_OUTPUT Makefile, check that
the directory is documented in README. Also skip non distributed
directories in readme.test.
* README: Fit on 80 columns.
kills a memory leak warning from swig/python.
* src/ltlparse/public.hh (parse_error_list): Declare
as an empty struct for Swig.
* wrap/python/tests/ltlparse.py: Fix copyright.
* src/ltlvisit/length.cc (visit(multop*)): New function. "a & b &
c" has length 5, not 4, even though it is stored as And(a,b,c).
This caused reduc.test to fail on some formulae.
