[R] RE: [R-gui] NEdit Highligth patterns for R

[Ernesto Jardim]

Hi

I agree with your comments and of course you identifie the problems
regarding the implementation of your suggestions.

Of course we'd need bidireccional communication to implement it. I think
it's impossible to do it statically.

What I want with NEdit is a very ligth editor (which jedit is not) that
highlights the most important language syntax, so that It becomes easier
to write functions and scripts. I get that with NEdit.

Of course there's a lot that can be further developed and NEdit seems
very flexible and easy to use.

Regards

EJ
