3 * VIM - Vi IMproved by Bram Moolenaar
4 * MacVim GUI port by Bjorn Winckler
6 * Do ":help uganda" in Vim to read copying and usage conditions.
7 * Do ":help credits" in Vim to see a list of people who contributed.
8 * See README.txt for an overview of the Vim source code.
13 * Coordinates input/output to/from backend. A MMVimController sends input
14 * directly to a MMBackend, but communication from MMBackend to MMVimController
15 * goes via MMAppController so that it can coordinate all incoming distributed
18 * MMVimController does not deal with visual presentation. Essentially it
19 * should be able to run with no window present.
21 * Output from the backend is received in processInputQueue: (this message is
22 * called from MMAppController so it is not a DO call). Input is sent to the
23 * backend via sendMessage:data: or addVimInput:. The latter allows execution
24 * of arbitrary strings in the Vim process, much like the Vim script function
25 * remote_send() does. The messages that may be passed between frontend and
26 * backend are defined in an enum in MacVim.h.
