I have the start of a terminal capabilities library implementation at:


it is very unfinished but in the spirit of "release early, release
often" here it is.  It will read the /etc/termcap of a Unix-like machine
and parse out the capabilities, currently it doesn't deal with
capabilities that take positional parameters (like cursor movements) but
it does deal nicely with stuff like 'cl' (Clear Screen), 'ho' (home
cursor), 'so' (start standout mode) and so forth.  There are properties
for some of these capabilities.

Typical usage to clear the screen for instance might be:

using System;
using Unix.Console;

public class Foo
	public static void Main()
		TermCap tc = new TermCap();
                  Or generically:

I think there probably will be some issues with character encodings and
the like on some terminals and I would be happy to accept any
suggestions how to overcome this.

Flames, patches, suggestions and offers of help greatly accepted.

Hope it is useful.
