Hi guys,

I have been working on an intellij plugin which is here: 
https://github.com/kingsleyh/DLanguage

I only started learning D a couple of weeks ago and I haven't 
written an intellij plugin before - and also I'm not very 
familiar with parsing/lexing.

On my first pass - I got all the infrastructure working - e.g. 
run configurations, project creation, file creation etc. And I'm 
working on a BNF and JFlex by hand - but I realise it will take 
some time - so I have a branch which implements the DDT 
parser/lexer so I could get something working while I work on the 
bnf - however it breaks the contextual run configurations - which 
is pretty much essential for the plugin to be useful.

I'd like to get the DDT parser/lexer working but I'm not really 
sure where to go from where I am now. My DDT branch is called 
with_ddt.

If anyone has any pointers to what I need to do next that would 
be very helpful - even in terms of reading or reference material. 
I guess it all comes down to the DParserDefinition class - as my 
master branch uses a FlexAdapter which gives access to the 
context. But in the with_ddt branch its just using the DParser - 
which I think needs to have the hooks into the AST tree 
implemented or something like that.

Anyway let me know if you have any pointers or offers of help :)
