Default Alarm & Timer
======================
This provides an app, widget, library and tools for alarms and timers.
This allows you to add/modify any running timers.
Other apps can use this to provide alarm functionality.
App
---
The Alarm app allows you to add/modify any running timers.
Internals / Library
-------------------
Alarms are stored in an array in `alarm.json`, and take the form:
```
{
id : "mytimer", // optional ID for this alarm/timer, so apps can easily find *their* timers
on : true, // is the alarm enabled?
t : 23400000, // Time of day since midnight in ms (if a timer, this is set automatically when timer starts)
dow : 0b1111111, // Binary encoding for days of the week to run alarm on
// SUN = 1
// MON = 2
// TUE = 4
// WED = 8
// THU = 16
// FRI = 32
// SAT = 64
msg : "Eat chocolate", // message to display
last : 0, // last day of the month we alarmed on - so we don't alarm twice in one day!
rp : true, // repeat
vibrate : "...", // pattern of '.', '-' and ' ' to use for when buzzing out this alarm (defaults to '..' if not set)
as : false, // auto snooze
timer : 5*60*1000, // OPTIONAL - if set, this is a timer and it's the time in ms
js : "load('myapp.js')" // OPTIONAL - a JS command to execute when the alarm activates (*instead* of loading 'alarm.js')
// when this code is run, you're responsible for setting alarm.on=false (or removing the alarm)
data : { ... } // OPTIONAL - your app can store custom data in here if needed
}
```
You app
The [`alarm` library](https://github.com/espruino/BangleApps/blob/master/apps/alarm/lib.js) contains
a few helpful functions for getting/setting alarms, but is intentionally sparse so as not to
use too much RAM.
It can be used as follows:
```
// add/update an existing alarm
require("alarm").setAlarm("mytimer", {
msg : "Wake up",
timer : 10*60*1000, // 10 Minutes
});
// Ensure the widget and alarm timer updates to schedule the new alarm properly
require("alarm").reload();
// Get the time to the next alarm for us
var timeToNext = require("alarm").getTimeToAlarm(require("alarm").getAlarm("mytimer"));
// timeToNext===undefined if no alarm or alarm disabled
// delete an alarm
require("alarm").setAlarm("mytimer", undefined);
// reload after deleting...
require("alarm").reload();
// Or add an alarm that runs your own code - in this case
// loading the settings app. The alarm will not be removed/stopped
// automatically.
require("alarm").setAlarm("customrunner", {
js : "load('setting.app.js')",
timer : 1*60*1000, // 1 Minute
});
```
If your app requires alarms, you can specify that the alarms app needs to
be installed by adding `"dependencies": {"alarm":"app"},` to your metadata.
It uses the [`sched` library](https://github.com/espruino/BangleApps/blob/master/apps/sched) to handle the alarm scheduling in an efficient way that can work alongside other apps.
