Hi, I've developed an IDE for a general purpose language.
The actual parser it's a recursive descent hand written.
I would substitute the actual parser with an auto generated one, and I
firstly try using the ResourceSet mechanism, but the problem is that the
bootstrap of injectors made the process slow, like two or three seconds
profiling the code.
My question is: can I use directly my InternaJolieParser, removing the
use of Guice and hacking the code (istantiatin old style the Grammar
Access)? It is extremely hard? Thank you very much

Of course you can try, but I'd neither recommend to use the parser
without Guice, as we wire up almost everything using DI, nor hook in a
hand written parser, as we also have a couple of expectations on the
behaviour of the parser, such as error recovery, AST and especially node
model construction, etc. which I think will be extremely hard to fulfill
in your own parser implementation.
The injector should be instantiated only once, and to wait 2 seconds for
a bunch of plugins to be loaded seems to be quite common in Eclipse.
