built-in editor underlining

Hello Parlamis,

a tip regarding syntax highlighting you may (or may not ;-) find  
useful:
I'm using BBEdit 7.1 to edit my R-files. Of course, as a  
specialized tool,
it is far superior compared with R.app's built-in editor (no insult
intended). My workflow of editing-sourcing-editing is quite  
comfortable --
whether you switch to an internal or an external editor window  
makes no
difference.

I set the syntax coloring to Tcl, which gives a quite reasonable
highlighting of R/S code. And hopefully someone comes up with a  
special
language module in the future. The current version of BBEdit is  
8.5, and if
you don't need all its refinements, you can use their free  
TextWrangler,
which has pretty much the same basic functionality.

Hope that helps
(not sure, though :-)

Thanks, Simon.  Of course I don't think you should do anything that
would prohibit sourcing the file (and I guess most would agree).

Re: syntax coloring.  I've turned it off because, when editing the
beginning of a long file, I would get a long delay (multiple seconds)
after I entered an open quotes (") as the rest of the document
changed color because all quotes were now matched differently.  Not
sure whether this is a slow implementation of that functionality, or
what is to done about it, but for this user at least, the delay issue
outweighs any benefit that I could get from syntax coloring.

The build-in editor doesn't store any text attribute changes as the
output is plain text. It does, however, allow text attribute
changes, because they are used e.g. for syntax highlighting.
Strictly speaking the bug is that you can use the <Cmd><U> command
at all.

Another approach would be to enhance the editor to support RTF
format (internally it actually does allow it) which would allow you
to use formatted text and store it. The drawback is that such a
text is no longer executable directly in R, so you couldn't
"source" it. I not quite sure what is more useful - I'm almost
inclined to think that banning text format changes makes more
sense, but I'm open to other suggestions...

Cheers,
Simon

and then underline the first "Help" (by highlighting it, and using
either Meta-U  or Format>Font>Underline), the underlining will show
up in my current session.  but if i save the document and reopen  
it,
the underlining will be gone.  what is more, if i then open the
document in another text editor (try TextEdit), highlight the first
help and try to underline it, everything in the document will be
underlined, including the second "Help"

i've been using 2.4.0 alpha (about a week old) and the R.app
deployment build (Version 1.17-pre (3779)) for R 2.4.x from http://
