Hello,

Yes, I've got an interface which communicate via the clip-board.It's
quite primitive but fairly useful and also generates marks for your
function definitions.  The stuff below works with Alpha.6.02. 
The code isn't as clean as it should be and doesn't colorize (but see
Matias Giovannini's post for a way to add this).

Since camllight isn't scriptable by AppleScript, the way the interface
works is by, within Alpha, generating caml-light toplevel phrases and
copying them to the clipboard. Alpha then places caml-light in the foreground
and a simply paste command + enter in the caml-light input window executes
the command. It's ugly, but much better than typing things in directly...
Some menu options aren't implemented (be my guest).

Also, it would be easy to adapt this interface to work with Coq...

The code comes in portions: one to add to the existing system file modeDefs.tcl,
another to place in its own file camlMode.tcl. Read the code. Remember to
set camlPath to the appropriate value in file camlMode.tcl.

Cheers,
Claudio
