[R-gui] NEdit Highligth patterns for R
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

Hi
I've just submitted to the NEdit development team a R highligth patterns for NEdit (www.nedit.org).
NEdit is a text editor for LINUX which I use to write small R functions. In my opinion is a very good tool for small scripts, maybe for huge projects is not the best.
I'm attaching the R-5.1.pats file so you can try it.
As usual contributions and comments are welcome.

Nice. But regarding synthax highlighting, I stick with two problems:
1) It would be interesting to highlight in different colors functions and
arguments... but they can have same name. Example: plot(x, col=2) -argument
'col' and col(x), function 'col'. For the moment, the only easy way I found
is to define argument followed by = in the dictionnary, like 'col=' for the
argument. However, space is allowed between 'col' and '=', and then the
argument is not correctly coloured. So, I add an automatic correction that
eliminates spaces before a single '=' sign. But now that '=' is also allowed
as asignment, it is problematic: col = 1, with 'col' being the name of a
variable (indeed, col <- 1) is now highlighted as an argument.
2) Of course, one could statically define the dictionnary with, let's say,
all functions and arguments in the base and recommended packages. I would
prefer a dynamic construction of the dictionnary: when a library is loaded,
terms are added, when it is unloaded, they are eliminated. This is only
possible with a bidirectionnal communication between the editor and the R
calculation kernel. I got this in SciViews but how to do that in Nedit or
other separate script editors?
