MMM-pages

Project status

This project is mature and in maintence mode only. New features or fixes will not be actively made. If you'd like to see a feature or fix, please create a pull request.

This repo is not abandoned. I will still respond to PRs, but support requests or bugs reports will not be monitored.

If you'd like to be a maintainer to drive new features forward, please contribute to this repository before asking for maintainership. As this module is used by a lot of people, I need to ensure that a new maintainer can write high quality code and match the standards of the existing codebase.

Description

This MagicMirror² module allows you to have pages in your MagicMirror! Want to have more modules in your MagicMirror, but want to keep the format? Or, want to have grouped modules that are themed together? Look no further!

Note that this module does not provide any method of manually changing the page! You should ask other developers to add a notification to their modules, or add one yourself!

Installation

In your terminal, go to your MagicMirror's module directory:

cd ~/MagicMirror/modules

Clone this repository:

git clone https://github.com/edward-shen/MMM-pages

Configure the module in your config.js file.

To display what page you're on, I'd highly recommend checking out my page indicator module.

Using the module

To use this module, add it to the modules array in the config/config.js file.

Note: module names used in the following example are fictitious.

modules: [
    {
        module: 'MMM-pages',
        config: {
                modules:
                    [[ "newsfeed" ],
                     [ "calendar", "compliments" ]],
                fixed: [ "clock", "weather", "MMM-page-indicator" ],
                hiddenPages: {
                    "screenSaver": [ "clock", "MMM-SomeBackgroundImageModule" ],
                    "admin": [ "MMM-ShowMeSystemStatsModule", "MMM-AnOnScreenMenuModule" ],
                },
        }
    }
]

Configuration options

Option	Type	Default Value	Description
`modules`	`[[String...]...]`	`[]`	A 2D String array of what each module should be on which page. Note that all entries must take their class name (e.g. this module's class name is `MMM-pages`, while the default modules may just have `newsfeed`, without the `MMM-` prefix.
`fixed`	`[String...]`	`["MMM-page-indicator"]`	Which modules should show up all the time.
`excludes`	NA	NA	Deprecated. Use `fixed` instead.
`hiddenPages`	`{String: [String...]...}`	`{}`	An Object defining special `hiddenPages` which are not available on the normal page rotation and only accassible via a notification. Modules defined in `fixed` are ignored and need to be also added if you wish to have them on any hidden page.
`animationTime`	`int`	`1000`	Fading animation time. Set to `0` for instant change. Value is in milliseconds (1 second = 1000 milliseconds).
`rotationTime`	`int`	`0`	Time, in milliseconds, between automatic page changes.
`rotationDelay`	`int`	`10000`	Time, in milliseconds, of how long should a manual page change linger before returning to automatic page changing. In other words, how long should the timer wait for after you manually change a page. This does include the animation time, so you may wish to increase it by a few seconds or so to account for the animation time.
`rotationHomePage`	`int`	`0`	Time, in milliseconds, before automatically returning to the home page. If a home page is not set, this returns to the leftmost page instead.
`rotationFirstPage`	NA	NA	Deprecated. Use `rotationHomePage` instead.
`homePage`	`int`	`0`	Which page index is the home page. If none is set, this returns to the leftmost page instead.
`useLockString`	`bool`	`true`	Whether or not to use a lock string to show or hide pages. If disabled, other modules may override when modules may be shown. Advanced users only. Only override this if you know what you're doing.

For the module configuration option, the first element of the outer array should consist of elements that should be on the first page. The second element should consist of elements that should be on the second page, and so forth.

Notifications

The following is the list of notifications that MMM-pages will handle:

Notification	Payload type	Description
`PAGE_CHANGED`	`int`	MMM-pages will switch to the provided page index.
`PAGE_INCREMENT`	`int`, Optional	MMM-pages will increment the page, or by `n` times if a number is provided. Not providing a number is equivalent to sending a payload of `1`. If there are no more pages to increment by, this will loop around to the first page.
`PAGE_DECREMENT`	`int`, Optional	MMM-pages will decrement the page, or by `n` times if a number is provided. Not providing a number is equivalent to sending a payload of `1`. If there are no more pages to decrement by, this will loop around to the last page.
`QUERY_PAGE_NUMBER`	None	MMM-pages will respond with `PAGE_NUMBER_IS` with the current page index.
`PAUSE_ROTATION`	None	If MMM-pages is set to rotate, this will pause rotation until a `RESUME_ROTATION` notification is sent. This does nothing if rotation was already paused.
`RESUME_ROTATION`	None	If MMM-pages was requested to pause rotation, this will resume automatic rotation. This does nothing MMM-pages was not requested to pause.
`HOME_PAGE`	None	Return to the home page. If no home page is provided, return to the first page instead.
`SHOW_HIDDEN_PAGE`	`String`	MMM-pages will switch to the provided hidden page name.
`LEAVE_HIDDEN_PAGE`	None	MMM-pages will leave the currently showing hidden page and return to the previous showing page index.

The following is the list of notifications that MMM-pages sends out:

Notification	Payload type	Description
`MAX_PAGES_CHANGED`	`int`	This is sent only once during initialization of MMM-pages. This contains the number of pages defined in `config.js`.
`NEW_PAGE`	`int`	This notification is sent out on every page change and contains the current page index. This is to help other modules keep track of what the current page is. This is also sent out during initialization.
`PAGE_NUMBER_IS`	`int`	Sent in response to a `QUERY_PAGE_NUMBER` notification. Returns the current page index. This notification sends the same payload as `NEW_PAGE`.

Notes

This module responds to the notification PAGE_CHANGED and the payload strictly must be an integer. Note that this has strict error checking, so "3" will not work, while 3 will.

This module keeps track of pages by their index rather than their page number, so the leftmost page has an index of 0, the page to the right of that has an index of 1, and the page to the right of that has an index of 2. Thus, to change to the third page, your module should send out:

this.sendNotification("PAGE_CHANGED", 2);

This module keeps internal track of how many pages you have, defined by your config in the config file. There is no way to dynamically change the pages you have. If there arises a need, please create an issue.

This module does not enforce how other modules represents or even responds to MMM-pages notifications.

Initialization

This section provides documentation on what notifications the module sends on startup. This section isn't necessary to read for most users.

MMM-pages doesn't activate until we receive the DOM_OBJECTS_CREATED notification, as that notification ensures all modules have been loaded. On this notification, we send two notifications out, MAX_PAGES_CHANGED and NEW_PAGE, so other modules that would like to keep synchronized of the starting page and max pages have a way to determine which page to start on.

Hidden pages

The idea behind hidden pages is to be able to create special "modes" which are totally configurable by the user and are seperated from the "normal" MM² operation. Some examples would be a "guest", "admin" or "screensaver" mode, where only very specific modules are shown and you do not want to have them in your normal page roation.

These hidden pages are only accessible via notifications, so you need to send them from other modules. Examples integrations could be with touch, bots or voice commands. See also FAQ below.

FAQ

How do I interact with different pages?

MMM-pages intentionally does not provide methods to interact with the pages. This is intentional by design, as there are too many ways to interact with a MagicMirror. MMM-page-indicator does provide a way to click on the circles to change pages, but this requires the ability to click or tap on the circles itself. If no other method is available, MMM-pages provides an automatic rotation feature.
Help! My module is (above/below) another module in the same region but I want it to be somewhere else!

The order of your config.js determines your module location. If you have two modules, both with position:bottom_bar, the one that is first listed will appear on top. The rest will appear in the same order you defined them in. If you want this module to be at the very bottom, define this module as the last module in your config.js file. If you want it to be on top in that region, make sure no other module is defined before it that has the same region.
