Hello NG,

for my thesis I need a parser generator for generating a parser for a
language similar to OQL (Object Query Language). I already found a lot
of parser generators in the web or books but I need a special
functionality which is not provided by every generated parser. Namely
I need a preview which token comes next in an uncomplete input string.
For example when you type "select abc" the preview would be "from". Or
in "select abc from def where abc" the preview would be "<, <=, >, >=,

I already looked at
- ANTLR (LL) which does not provide this funcionality
- JavaCC (LL) provides it
- JavaCUP (LALR) does not provide
- SableCC (LALR) provides it

Of course a LALR parser would be better because the grammar can be
written down in an easier way.

Do you know any parser with the functionality mentioned above?

Thanks and regards,
Ulrich Frank
