All init functions are * wrapped in another function before being run in a thread (i.e. run indirectly). Functions fail * either by throwing an exception or by returning a boolean. Functions may take parameters, e.g. * "out cleanupFunc[]". * * This should make it much easier to tell what actually happens during init and to order init such * that dependencies are honoured. * * Currently some external modules depend on InitFunctions, while some are set up from here. Once * all are set up from here, the Init* modules can be rearranged. */ /* Idea: go back to init being controlled from elsewhere. Add a function to wait for another init * function to complete (threaded; might need to be done differently for non-threaded). */ module mde.setup.init2; import mde.setup.initFunctions; import tango.util.log.Log : Log, Logger; // Modules requiring init code running: import imde = mde.imde; import mde.gui.Gui; import mde.input.Input; import font = mde.font.font; // NOTE: error reporting needs a revision private Logger logger; static this () { logger = Log.getLogger ("mde.setup.init2"); init.addFunc (&initInput, "initInput"); init.addFunc (&guiLoad, "guiLoad"); } void guiLoad () { // init func try { font.FontStyle.initialize; gui.load (GUI); cleanup.addFunc (&guiSave, "guiSave"); } catch (Exception e) { logger.fatal ("guiLoad failed: " ~ e.msg); setInitFailure; } } void guiSave () { // cleanup func try { gui.save (GUI); } catch (Exception e) { logger.fatal ("guiSave failed: " ~ e.msg); setInitFailure; } } private const GUI = "gui"; void initInput () { // init func try { imde.input.loadConfig ("input"); // Quit on escape.
