DDT and Descent

[Jeremy Powers]

Recently I was poking around seeing what it would take to create a D
plugin for IntelliJ, and took a look at DDT as a staring point.

There is a relation between the DDT project and the Descent compiler
that isn't clear to me - on the one hand, they are separate, with
separate repositories, but on the other descent.compiler contains
references to DDT in the build...

Is the descent compiler now considered a sub-project of DDT, owned and
maintained by the same folks, or is it 'legacy', or what?  What is the
future path for the descent.compiler vs. DDT?

As mentioned, my interest is in re-using parts for a separate IDE
plugin (having used Eclipse for years, I am heavily biased towards
IntelliJ).  From a first glance it looks like the descent.compiler
only has some _very_ minimal dependencies on Eclipse/OSGI, and could
easily be a reusable lexer/parser library for any java code what needs
it.  It looks like there hasn't been any changes to descent.compiler
in quite some time (latest was an addition of ddt referencing pom.xml)
- is Descent still considered an active project on its own, or is it
being fully consumed by DDT, or somewhere in the middle?

Thanks,
Jeremy
