[Rd] Color coding
I'm probably not the first with this idea so I guess that there's a complex issue behind it but since I couldn't find an answer I just though to ask: Wouldn't it be nice to have color coded objects as output of ls() statement? Functions of one color and rest with other (at least). So when I issue an ls() I could visually discern different types of objects. I often find myself opening old files and spending time figuring which is which. I know this just means I'm not aoranized, but still...color coding would help.

Re: [Rd] (PR#10437) segfault on functions with 'source' attribute
For the record: The reason I used attr(myfun, "source") = FALSE, is that I misread the example 'Tidying R Code' in 'Writing R Extensions', which calls for attr(myfun, "source") = NULL. Somehow setting 'source' to FALSE seems more natural to me than setting it to NULL.

You haven't mentioned your platform: you would have to be working in a console which supported this, and e.g. the Windows GUI console does not. Once you know the escape codes to change colour, it would be easy to write a listing function which did this. You would almost certainly have to write some C code to find out what the codes are for the current terminal (on a modern system via the terminfo database): the GNU ls (part of coreutils) would provide you example code. So, this is project for a package: are you volunteering? -- Brian D.

Re: [Rd] Color coding
Unfortunately, the problem is the way the R output is set up---there's no portable way (at the moment) to tag output with different attributes.
