digitalmars.D.ide - microEmacs in D

I finally got around to translating microEmacs from C into D. It's still 
in "C style", though :-)

ftp://ftp.digitalmars.com/med.zip

microEmacs is a simple text editor, easily customizable, portable, and 
is a great project to learn programming from. It's in the public domain.

For those wanting to have some fun with it, some projects could be:

1) add regular expression searching
2) use std.algorithms to implement a "sort" function on a range
3) for the really ambitious, add in dmdscript as a way for users to 
script microEmacs

Should probably mention that it's D2.

Also it seems to be missing disp.d.  There's a display.d, but several 
files are importing "disp".  Not sure if they're supposed to be the same 
thing or not.

In what way was this fixed? Is the import supposed to be 'disp' or
'display'? There are a number of references to functions like "disp_..."
that are not being found. eg. console.d line:65 has "disp_open();".

I had forgotten to add disp.d to the zip file, which I then did and 
uploaded.

And did you update the zip on ftp too?  Seems unchanged.

Ah, I see the problem, I copied the wrong file. Please try again.

Still doesn't compile (dmd 2.010).

console.d:32 "static INPUT_RECORD lookaheadir;" - what is an INPUT_RECORD?

Looks like maybe some bit of Windows API Walter hasn't checked into 
std.c.windows.windows yet:

My bad, i hadn't unpacked dmd 2.011 yet.  Those structs were indeed 
added to std.c.windows.windows in 2.011 so Walter could compile microemacs.

... but now I get a link error:

f:\usr\pkg\d2\dmd\bin\..\lib\phobos.lib(stdio)
  Error 42: Symbol Undefined _popen

OS is WinXP.

As a workaround, you can stick in a function:

	extern (C) void popen() { assert(0); }

Ah, I went ahead and did that and uploaded a new zip file.

Need dmd 2.011 with the updated windows API.
