# Kaleidoscope-HostPowerManagement

Support performing custom actions whenever the host suspends, resumes, or is
sleeping.

## Using the plugin

To use the plugin, one needs to include the header, and activate it. No further
configuration is necessary, unless one wants to perform custom actions.

```c++
#include <Kaleidoscope.h>
#include <Kaleidoscope-HostPowerManagement.h>

KALEIDOSCOPE_INIT_PLUGINS(HostPowerManagement);

void setup () {
  Kaleidoscope.setup ();
}
```

## Plugin methods

The plugin provides the `HostPowerManagement` object, with no public methods.

## Overrideable methods

### `hostPowerManagementEventHandler(event)`

> The `hostPowerManagementEventHandler` method is the brain of the plugin: this function
> tells it what action to perform in response to the various events.
>
> Currently supported events are:
> `kaleidoscope::plugin::HostPowerManagement::Suspend` is fired once when the
> host suspends; `kaleidoscope::plugin::HostPowerManagement::Sleep` is fired
> every cycle while the host is suspended;
> `kaleidoscope::plugin::HostPowerManagement::Resume` is fired once when the
> host wakes up.
>
> The default implementation is empty.
