I was looking for good nano syntax highlighting code for R when I found by Stephen Haptonstahl's code here:
http://srh.ucdavis.edu/drupal/node/20He is happy for others to use the code, modify it and distribute it. My edited version of his code is attached. To use it, just append it to your ~/.nanorc file. There's also a systemwide way to use it, but I don't know offhand. To use nano in a view-only mode, just use the -v option to turn off editing functionality:
nano -v file.RThe .R file extension will cause Nano to use the R syntax highlighting, but it can also be triggered with the -Y option:
nano -v -Y R file.whateverOf course, nano also is an editor, so just drop the -v option if you want to edit a file.
The screenshot looks pretty nice now (I'm using xterm with white on black and haven't tested with black on white), but I'm sure it can be improved further. I don't have time to work on it much now, but maybe someone else will want to pick it up.
