Alternating Modules to save on real estate

KirAsh4

By the way, this works best if the two modules you are trying to swap are right below each other in the 'config.js' file. For example, if you’re trying to swap ModA and ModB, your 'config.js' should list them together

modules: [
		{
			module: 'ModA',
		},
		{
			module: 'ModB',
		},
],

if you have a ModC in between them, it won’t ‘swap’ properly, it’ll just turn them off in alternate fashion while keeping them in their respective location. So you’ll end up with:

startup
ModA
ModC
ModB

then
ModC
ModB

then
ModA
ModC

alternating ...

Not particularly ideal …

Thanks! I messed around a bit with it - here is what I came up with. (and yes, 99.999% is yours!)
Still, here it is for anyone else who wants to play with it. But ALL credit goes to @KirAsh4

This works best for me for MMM-Wunderground and MMM-Wunderlist - which I keep at top-right.
a) my config.js extract:

                {
                        module: 'my_swap',      // as supplied by KirAsh4
                        config: {
                                showsecs: 30,   // seconds each module is shown (default =30)
                                                // 30 is a "relaxed" speed
                                fadems: 4000,   // fade time in ms (default = 4000)
                                                //  4000 is also very relaxed - no coffee yet.
                                modA: 'MMM-WunderGround',  // both modules need to be listed NEXT
                                modB: 'MMM-Wunderlist'     // they should be of similar size, 
                                                           // and in the same location.
                                                           // These two are _prefect_ 
                                }
                },
                {
                        module: 'MMM-WunderGround',
                        position: 'top_right',
                        config: {
                                apikey: '****',
                                pws: '****',
                                lang: 'EN',
                                fctext: '1',
                                fcdaycount: "5",
                                fcdaystart: "0",
                                hourly: '1',
                                hourlyinterval: "3",
                                hourlycount: "1",
                                alerttime: 10000,
                                alerttruncatestring: "english:",
                                fade: true
                        }
                },
                {
                        module: 'MMM-Wunderlist',
                        position: 'top_right', 
                        config: {
                                accessToken: '****',
                                clientID: '****',
                                lists: [
                                        'MagicMirror'
                                        ],
                                interval: 60,
                                fadePoint: 0.9,
                                fade: true
                                }
                },

Then the file my_swap.js ( in \modules\my_swap) needs to look like this:

Module.register("my_swap",{

  // Default module config.
  defaults: {
        modA: "MMM-NonExistA",  // if we dont know the EXACT NAME, we don't do anything!
        modB: "MMM-NonExistB",  //    ="=
        showsecs: 30,           //  as in compliments
        fadems: 4000            //    ="=
  },

  // Define required scripts.
  getScripts: function() {
    return ["moment.js"];
  },

  start: function() {
    Log.log("Starting module: " + this.name);
    this.DOMloaded = 0;
    this.isHidden = 0;

    var self = this;
    setInterval(function() {
      self.swapModules();
    }, 1000);
  },

  notificationReceived: function(notification, payload, sender) {
    if (notification === 'DOM_OBJECTS_CREATED') {
      this.DOMloaded = 1;
    }
  },

  // swapModules.
  swapModules: function() {

    var now = moment();
    var self = this;

        var mod1 = this.config.modA     // yank from config file
        var mod2 = this.config.modB
        var fadems = this.config.fadems
        var showsecs = this.config.showsecs

    if (!(now.seconds() % showsecs)) { 
      if (this.DOMloaded) {
        if (self.isHidden) {
          MM.getModules().exceptModule(this).enumerate(function(module) {
            if (module.name === mod1) {
              module.hide(fadems, function() {
                MM.getModules().exceptModule(this).enumerate(function(module) {
                  if (module.name === mod2) {
                    module.show(fadems, function() {
                    });
                  }
                });
              });
            }
          });
          self.isHidden = 0;
        } else {
          MM.getModules().exceptModule(this).enumerate(function(module) {
            if (module.name === mod2) {
              module.hide(fadems, function() {
                MM.getModules().exceptModule(this).enumerate(function(module) {
                  if (module.name === mod1) {
                    module.show(fadems, function() {
                    });
                  }
                });
              });
            }
          });
          self.isHidden = 1;
        }
      }
    }
  }
});

Works great for me! Thanks again for the clean code to play with. You should submit it as an official module.

Yep, what you did is pretty much the idea. You figured it out and used your modules in the code. It needs to be rewritten a bit to allow for configurable module names. Possibly also allow more than just 2 modules to be swapped. There are some other things I can think of but it’s not something that’s at the top of the list for me. It is sitting in my dev repository, but it’ll be a bit before I focus on it. I’m glad what I wrote is helping you out though.

@KirAsh4 Is it also possible to create alternating modules from the same type? In my case, I’m trying to alternate 2 calendar modules. Thank you very much for your answer.

Unfortunately, no. You can only alternate between the two modules, as prescribed in the manual.
