Re: [cdt-dev] LR parser and LPG version
|
Its easiest to get the LPG 1.1 runtime from Orbit. Find the org.eclipse.orbit folder in CVS and check out the net.sourceforge.lpg.lpgjavaruntime project. The project will initially be empty, right click on the project and select Team > Switch to another branch or version, then select the v1_1 branch. That will give you a project with all the source for LPG 1.1 in your workspace, which is very useful.
Alternatively I think you can download the runtime as a plugin jar from the orbit page on eclipse.org and just drop it in your plugins folder. The sourceforge page provides the runtime as a normal jar file, but its the orbit project that provides a plugin wrapper for the jar so that it can be used easily with eclipse.
I'm getting enough requests for documentation for the LR parser that I think I'm going to have to start writing some :)

Re: [cdt-dev] LR parser and LPG version |
Hi,
I was just wondering if there are any instructions for using the LR
parser, for example where do I get net.sourceforge.lpg.lpgjavaruntime?
I downloaded the org.eclipse.cdt.core.lrparser plugins from CVS and
the LPG distribution zip, as well as some code from
lpg.cvs.sourceforge.net but I'm a bit lost as I can't find a bundle
called net.sourceforge.lpg.lpgjavaruntime.
Thanks,
Mike
