This message describes the current status of Syntaxis . In short,
I've fixed a few bugs, upgraded the tool to Java 7 and the C++ engines
to gcc 4.4. New features will not be added in the near future.
First, Syntaxis has been upgraded to compile and run with both Java 6
and Java 7. The Mac OS X specific application requires Java 7. The tool
has been tested with OpenJDK, Java HotSpot & J9 virtual machines on a
variety of systems, including Win XP, Vista, Red Hat, and Mac OS X. The
most stable environment seems to be the Java HotSpot 1.7 on Windows.
Second, the C++ parser engines compile with MSVC 2002 on XP, gcc 3.2 on
Red Hat 9, gcc 4.4 on Red Hat/CentOS 6.3, and on Mac OS X 10.7 with both
gcc 4.2 and Apple LLVM 4.0 compiler. One has to rewrite the C++ parser
engines to create a professional quality parser.
Third, the experimental LALR' Builder I've mentioned in a previous
message  seems to be relatively stable. The last bug I fixed (?) had
been found in lookaheads propagation. So, the workaround mentioned in
message  is no more necessary for that large, conflicts free, FORTRAN
parser. The only keyword recognized by the lexer with forward scanning
is the keyword "format". So, the technique described in  seems to be ok.
Last but not least, the demo version of Syntaxis remains available for
evaluation upon request; it includes the parser generator that creates
Java packed parsers [1&4]. I've tested it with gcj 3.4 via cygwin, gcj
4.4.6 on CentOS 6.3, javac/jar 1.6 and 1.7.
