* src/hoaparse/hoaparse.yy: validate deterministic and
complete when parsing HOA. Also set the deterministic
property on the TGBA.
* src/tgbatest/hoaparse.test: Test errors.
* src/hoaparse/hoaparse.yy: Fix a map with properties, and use it to
report error when state-label or trans-label are misused.
* src/tgbatest/hoaparse.test: Test that.
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.
* src/kripketest/bad_parsing.test, src/tgbatest/neverclaimread.test,
src/tgbatest/readsave.test, src/tgbatest/hoaparse.test: Use Perl for the
unix2dos conversion.
Location tracking was incorrect for multi-line
strings/comments/parentheses. This also fixes and tests recovery on
inclosed strings/comments/parentheses.
* src/hoaparse/hoaparse.yy: Abort on expected EOF.
* src/hoaparse/hoascan.ll: Track newlines inside strings and comments.
Do not use unput() to close incomplete parentheses.
* src/tgbatest/neverclaimread.test, src/tgbatest/hoaparse.test: Add
more tests.
This way we can easily parse a stream of HOAs intermixed with
neverclaims.
* src/hoaparse/hoaparse.yy, src/hoaparse/hoascan.ll: Add rules
for neverclaims, adjusted from src/neverparse/neverclaimparse.yy
and src/neverparse/neverclaimparse.ll.
* src/hoaparse/public.hh, NEWS: Update documentation.
* src/neverparse/: Remove this directory.
* README, configure.ac, src/Makefile.am: Adjust accordingly.
* src/tgbatest/ltl2tgba.cc, src/bin/ltlcross.cc: Use HOA
parser to read neverclaims.
* src/tgbatest/hoaparse.test, src/tgbatest/neverclaimread.test: Adjust.
* src/hoaparse/hoascan.ll: Remove superfluous line.
* src/tgbaalgos/hoaf.cc: Do not call to_string() to display names, as
this would add another level of escaping.
* src/tgbatest/hoaparse.test: Test it.
* src/hoaparse/hoaparse.yy: Improve error reporting
in case labeled edges are mixed with unlabeled edges.
* src/hoaparse/hoascan.ll: Fix handling of nested comments.
* src/tgbatest/hoaparse.test: More coverage.
* src/hoaparse/parsedecl.hh (hoa_abort): New structure.
* src/hoaparse/hoascan.ll: Throw hoa_abort on --ABORT--.
* src/hoaparse/hoaparse.yy: Deal with this exception.
* src/hoaparse/public.hh: Add a boolean flag to mark aborted automata.
* src/bin/autfilt.cc: Report aborted automata.
* src/tgbatest/hoaparse.test: Add test case.
* src/hoaparse/hoaparse.yy: Allocate state after parsing the entire
header, not right after passing "States:".
* src/tgbatest/hoaparse.test: Reflect improved error message
about initial state.
* src/hoaparse/hoaparse.yy: Improve error recovery,
and fix location tracking in streams.
* src/hoaparse/public.hh: Store the last location so
that the next parse start at the correct position.
* src/bin/autfilt.cc: Stop parsing a stream on irrecoverable errors.
* src/tgbatest/hoaparse.test: Adjust tests.
