digitalmars.D.learn - Testing if a file is connected to a terminal

Is there a canonical way to test in D whether stdout/stderr (or in general, 
a std.stdio.File) refers to a terminal or not? 

https://www.google.co.in/search?q=terminal&sitesearch=dlang.org/phobos turns 
out nothing.

I knew of C's (or rather POSIX's) isatty, and after some digging I found 
isatty defined under core.sys.posix.unistd, and I suppose I can just pass to 
it the output of std.stdio.File.getFP.

Is there any other way to do the desired test? Or is this the recommended 
way?

We don't have any terminal functionality in Phobos at this time, 
so using isatty directly is the way to go.

There are some terminal libraries on Github (like consoled) but I 
have to say I think they're uninspiring in terms of quality and 
presentation.

Can you be any more specific about that?

Where's the reference documentation?

There's a README: http://code.dlang.org/packages/consoled, and the source 
does seem to have DDoc comments...

In the source...

but yeah, good point. I'm working on writing docs for a lot of my 
stuff. Terminal is still completely messed up

http://arsdnet.net/arsd/terminal.html

cgi is meh but there: http://arsdnet.net/arsd/cgi.html

simpledisplay is the one I've spent the most time on so far: 
http://arsdnet.net/arsd/simpledisplay.html


I'm pretty happy with how terminal.d works, but indeed the docs 
are still awful.
