RE: [dtp-dev] DTP 0.9 RC5 5/31 build
|
Hi David,
Yes -- we intend to have just one parser going forward (the common parser
API mentioned by Rupesh), which likely will allow for underlying
implementation selection. At that time, we'll use the LPG-based parser in
DTP. For the time being, we've used the JavaCC based one, and that might
serve as a good example of how to integrate with the SQL Dev Tools. If you
are interested in parsers specifically (as I think you are), then I'd
concentrate on the LPG based one.
Regarding the license issue: could you provide some details of your
concerns? We'll talk to the groups involved to get an answer.

Hi Max,
Thanks for your input, however I am a little confused about the fact that
we use two different parsers (JavaCC, LPG) in the framework, why don't we
just use one parser?
I read the EclipseCon tutorials, if I understand correctly, JavaCC is used
only for content assist and syntax highlighting etc. whereas LPG is more
powerful and flexible, it supports semantic validation and also generates
QueryStatement which I can use to extract parameters and result columns
information (this is very important to me). So I am confused at the point
as to which parser I should extend, JavaCC or LPG? Does JavaCC parser also
provide the similar function as LPG?
One last question, is IBM LPG parser used in the devtools the same as open
source as http://sourceforge.net/projects/lpg, because I am little concern
about the license issue with IBM parser.

Hi David,
Just a reminder that currently only JavaCC parser is integrated
with the DTP editor framework. You can check out the EclipseCon 2006 DTP
tutorial slides for details about how to contribute your own parser:

Hi David
Thanks for your interest.A common parser API (for callers to work with any
parser) is planned in the next release of DTP (post DTP 0.9 ). Changes are
expected in the current parser and its extension mechanism as well . I
think it is will be good to get involved and start with the extension when
this work begins.
At present, there is no documentation on extending the parser.If interested
you can look at .lpg files in
org.eclipse.datatools.sqltools.parsers.sql.xml.query plugin to get an idea
of the grammar. This plugin can be thought of an extension of the query
parser (org.eclipse.datatools.sqltools.parsers.sql.query) to support the
SQL/XML functions.An Oracle dialect extension will be similar. LPG is
opensource at http://sourceforge.net/projects/lpg
Thanks,
Rupesh Kartha,
