[q-lang-users] ANN: Q 7.4, Q Yacc/Lex 0.9

[Albert G. <Dr....@t-...>]

Hi,

I've just uploaded Q 7.4, which fixes a memory allocation bug in the 
compiler. Also now available: Q Yacc/Lex 0.9 with more speed 
improvements and bugfixes (a fairly complete Q grammar is now also 
included in this package).

The binary Q packages now also include the latest Q Yacc/Lex. As usual, 
all the good stuff is available from the Download page at 
http://q-lang.sf.net.

Cheers,
Albert

Builds and runs successfully on Cygwin.

Nice, thanks for the report.

Did anyone try the new Q Yacc/Lex yet? Q Yacc is still rather slow, so 
if anyone has an idea on how to further speed up the Q implementation of 
the LALR algorithm then please let me know. The generated parsers and 
scanners should be fast enough for practical purposes now, as I've 
reimplemented the internals of both yyparse and yylex in C. (They're 
still slower than pure C, as they call back into Q for the actions, but 
there's no way around that.)
