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 * MMAppController is the delegate of NSApp and as such handles file open
14 * requests, application termination, etc. It sets up a named NSConnection on
15 * which it listens to incoming connections from Vim processes. It also
16 * coordinates all MMVimControllers and takes care of the main menu.
18 * A new Vim process is started by calling launchVimProcessWithArguments:.
19 * When the Vim process is initialized it notifies the app controller by
20 * sending a connectBackend:pid: message. At this point a new MMVimController
21 * is allocated. Afterwards, the Vim process communicates directly with its
24 * A Vim process started from the command line connects directly by sending the
25 * connectBackend:pid: message (launchVimProcessWithArguments: is never called
28 * The main menu is handled as follows. Each Vim controller keeps its own main
29 * menu. All menus except the "MacVim" menu are controlled by the Vim process.
30 * The app controller also keeps a reference to the "default main menu" which
31 * is set up in MainMenu.nib. When no editor window is open the default main
32 * menu is used. When a new editor window becomes main its main menu becomes
33 * the new main menu, this is done in -[MMAppController setMainMenu:].
34 * NOTE: Certain heuristics are used to find the "MacVim", "Windows", "File",
35 * and "Services" menu. If MainMenu.nib changes these heuristics may have to
36 * change as well. For specifics see the find... methods defined in the NSMenu
37 * category "MMExtras".
