The initial thread. In gui_mch_prepare() this gets to run the + * BApplication message loop. But before it starts doing that, + * it creates thread 2 + * 2. The main() thread. This thread is created in gui_mch_prepare() + * and its purpose in life is to call main(argc, argv) again. + * This thread is doing the bulk of the work. + * 3. Sooner or later, a window is opened by the main() thread. This + * causes a second message loop to be created: the window thread. + * + * == alternatively === + * + * #if RUN_BAPPLICATION_IN_NEW_THREAD... + * + * 1. The initial thread. In gui_mch_prepare() this gets to spawn + * thread 2. After doing that, it returns to main() to do the + * bulk of the work, being the main() thread. + * 2. Runs the BApplication. + * 3. The window thread, just like in the first case. + * + * This second alternative is cleaner from Vim's viewpoint. However, + * the BeBook seems to assume everywhere that the BApplication *must* + * run in the initial thread. So perhaps doing otherwise is very wrong. + * + * However, from a B_SINGLE_LAUNCH viewpoint, the first is better. + * If Vim is marked "Single Launch" in its application resources, + * and a file is dropped on the Vim icon, and another Vim is already + * running, the file is passed on to the earlier Vim. This happens + * in BApplication::Run(). So we want Vim to terminate if + * BApplication::Run() terminates. (See the BeBook, on BApplication. + * However, it seems that the second copy of Vim isn't even started + * in this case... which is for the better since I wouldn't know how + * to detect this case.) + * + * Communication between these threads occurs mostly by translating + * BMessages that come in and posting an appropriate translation on + * the VDCMP (Vim Direct Communication Message Port). Therefore the + * actions required for keypresses and window resizes, etc, are mostly + * performed in the main() thread. + * + * A notable exception to this is the Draw() event. The redrawing of + * the window contents is performed asynchronously from the window + * thread. To make this work correctly, a locking protocol is used when + * any thread is accessing the essential variables that are used by + * the window thread. + * + * This locking protocol consists of locking Vim's window. This is both + * convenient and necessary. + */ + +extern "C" { + +#include <assert.h> +#include <float.h> +#include <syslog.h> + +#include "vim.h" +#include "globals.h" +#include "proto.h" +#include "version.h" + +} // extern "C" + +// ---------------- start of header part ---------------- + +//#include <Alert.h> +#include <Application.h> +#include <Beep.h> +#include <Bitmap.h> +#include <Box.h> +#include <Button.h> +#include <Clipboard.h> +#include <Debug.h> +//#include <Directory.h> +//#include <Entry.h> +#include <File.h> +#include <FilePanel.h> +#include <FindDirectory.h> +//#include <Font.h> +#include <IconUtils.h> +#include <Input.h> +#include <ListView.h> +#include <MenuBar.h> +#include <MenuItem.h> +//#include <MessageQueue.h> +//#include <OS.h> +#include <Path.h> +#include <PictureButton.h> +#include <PopUpMenu.h> +//#include <Region.h> +#include <Resources.h> +//#include <Roster.h> +#include <Screen.h> +#include <ScrollBar.h> +#include <ScrollView.h> +#include <String.h> +#include <StringView.h> +//#include <SupportDefs.h> +#include <TabView.h> +#include <TextControl.h> +#include <TextView.h> +#include <TranslationUtils.h> +#include <TranslatorFormats.h> +#include <View.h> +#include <Window.h> + +class VimApp;
