Nice!!! So you can write the same code for both the "shell library" and the actual shell itself.
Yeah. This is similar to the technique I used in my web.d thing, though web.d's is a lot more complex. (It also handles sub objects, argument name and default values, and some more.) I just find it super useful.
The echo command has a bug, it's not supposed to output 'echo' as part of its output. :)
Yeah, I messed up argv. Here's an updated version: http://arsdnet.net/dcode/dshell.d added basic formatting to the data interface, lazy printing (try "cat" and type in stdin) and bug fixes. I just might put it up on the github over the weekend.
It's extremely cool. Definitely orders of magnitude better than writing the equivalent thing in C.
Hell, this kind of thing is easier in D than in a lot of dynamic languages! imo anyway. eval is sometimes nice but having the type information available to do a smart wrapper is very nice.
