I am assuming you want to perform syntax highlighting or something like
that.
yeah - thats the first step.
second step is to maybe use the parser to provide code completion  
hints/syntax checking...but that is in the future.

It's a trivial thing, but consider something like "count" which is a
keyword depending upon usage.  Think of a mapped entity that has a
property named count, like maybe a line item.  In HQL I can say
something like:
"select sum(li.count) from LineItem as li where...".  Here, "count" does
not really represent a key-word.  The parser handles this by inspecting
the AST tokens around the "count" token.  The editor might not be able
to do something similar, and would not be able to ask the parser to
check unless you were continuously parsing the input.
well - in the beginning it will be a little detail/quirk...later we can  
look into
parsing this stuff again and again (and i expect the parser is efficient  
from day 1, right ? ;)

/max

Subject: [Hibernate] antlr "introspection" ?
Hi antlr-guys ;)
Is it possible to get information about keywords, operators etc. from
our
new HQL parser ?
something like: HQLParser.getLiterals(), HQLParser.getKeywords() etc.
or
maybe just a map from
tokens to their type or something ?
It would be a big plus for providing HQL editor support in eclipse ;)
