R help - May 2024 - Is there some way to customize colours for the View output?

Hi all,

As the email subject tells, I write to ask if there is the chance to customize
the colours (and in particular the background) of the `View` output window.


In the View help, it is told that:

    On Windows, the initial size of the data viewer window is taken from the
default dimensions of a pager (see Rconsole), but adjusted downwards to show a
whole number of rows and columns.

So if it works for the sizes, it could work for the colours. But after modifying

## Colours for console and pager(s)
# (see rwxxxx/etc/rgb.txt for the known colours).
background = gray9
normaltext = yellow
usertext = YellowGreen
highlight = golderod

I did not have success.

On the other hand, in the data.entry it is told that

    The data entry window responds to X resources of class R_dataentry.
Resources foreground, background and geometry are utilized.

But I do not know if this is related and how to modify those resources.

Can someone help me?

If this is not possible, is there any chance of making a feature request of this
to R-devel? (I mean, I could write to R-devel list, but do you think there would
be any interest in developing this?)

Thanks!
Best regards,

Iago

If you are using X11, then the paragraph on X resources is relevant. 
Create a file named .Xresources in your home directory, and put a line like

R_dataentry.background: green

in it.  On my Mac, this has to be in place before Xquartz is started. 
There is probably a similar restriction on other platforms.

Colour names (used for foreground and background) can be words or hex 
colors like #ffffff .  I don't know the format for "geometry", but
I'd
guess it's like the -geometry argument to X11 apps, e.g. 1000x1000+0+0.

If you are on Windows, none of this is relevant.

The Windows data editor lives in
src/library/utils/src/windows/dataentry.c [1]. There are references to
the array guiColors and indices dataeditbg, dataedituser, dataeditbg,
dataeditfg. I was able to find the colours with these names in the GUI
preferences, edit them and see an effect on the edit() window.
