Also get rid of the lbt_parser, and fix the LBT support of the HOA
parser.
* doc/org/ltlcross.org, doc/org/ltldo.org: Update.
* src/bin/common_trans.cc, src/bin/common_trans.hh: Add support for
%O, and keep %T,%N,%H as hidden aliases without disabling them.
* src/bin/ltlcross.cc, src/bin/ltldo.cc, src/tgbatest/ltl2tgba.cc:
Call hoa_parse instead of lbt_parse.
* src/hoaparse/hoaparse.yy: Improve error reporting from LBT.
* src/hoaparse/hoascan.ll: Fix typos preventing parsing of
LBT files with more than 10 states.
* src/tgbaalgos/lbtt.cc, src/tgbaalgos/lbtt.hh: Delete the lbt
parser.
* src/tgbatest/lbttparse.test: Adjust the expected error message.
* NEWS: Update.
* src/hoaparse/hoaparse.yy: forward the error messages
from lbt_parse().
* src/hoaparse/hoascan.ll: Minor cleanups.
* src/tgbatest/lbttparse.test: Test it.
This is probably the worse grammar I wrote: the LBTT format is designed
to be scanned with scanf, and very inconvenient to parse with
bison/flex. Here the scanner basically has to emulate a parser to
classify the different INTs as tokens with different types.
* src/hoaparse/hoaparse.yy, src/hoaparse/hoascan.ll: Add rules for LBTT.
* src/hoaparse/parsedecl.hh: Add a way to reset the parser between each
automata.
* src/tgbatest/hoaparse.test, src/tgbatest/lbttparse.test: Add more
tests.
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.
* src/tgbaalgos/lbtt.hh, src/tgbaalgos/lbtt.cc (lbtt_parse):
New function.
* src/tgba/tgbaexplicit.hh (get_acceptance_condition): Make it public.
* src/tgbatest/ltl2tgba.cc: Add a -XL option to read LBTT file.
* src/tgbatest/lbttparse.test: New file.
* src/tgbatest/Makefile.am: Add it.
