# MMM-pages
|
|
|
|
This [MagicMirror²][mm] Module allows you to have pages in your magic mirror!
|
|
Want to have more modules in your magic mirror, 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 folder:
|
|
|
|
```bash
|
|
cd ~/MagicMirror/modules
|
|
```
|
|
|
|
Clone this repository:
|
|
|
|
```bash
|
|
git clone https://github.com/edward-shen/MMM-pages.git
|
|
```
|
|
|
|
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][page indicator].

|
|
|
## 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 can be fictitious.
|
|
|
|
```js
|
|
modules: [
|
|
{
|
|
module: 'MMM-pages',
|
|
config: {
|
|
modules:
|
|
[[ "weatherforecast", "newsfeed"],
|
|
[ "calendar", "compliments" ]],
|
|
fixed: ["clock", "currentweather", "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. |
|
|
| `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. |
|
|
|
|
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. |
|
|
|
|
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. |
|
|
| `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:
|
|
|
|
```js
|
|
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.
|
|

|
|
|
|
## 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
|
|
Magic Mirror. [MMM-page-indicator][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.
|
|
|
|
- Can I make a pull request?
|
|
|
|
Please do! Feel free; I love improvements!
|
|
|
|
- I want more config options!
|
|
|
|
Please make an issue. Thanks!
