# battd
A simple battery daemon written for use with a daemontools-style supervisor.
`run` polls the status of a `check` function with a regular interval. On the
transition from a successful `check` exit status to an unsuccessful `check` exit
status the `failed` function is called.
## Installation
``` text
# ./install /etc/sv/battd
# ln -s /etc/sv/battd /var/service
```
Adjust the above as needed.
## Usage
Configure `conf` appropriately. This should contain three functions:
`interval`
: Called to determine the polling interval (see below).
`check`
: Called to determine the battery status.
`failed`
: Called when the battery status has transitioned from a successful to a
failing return.
Optionally two variables can be set:
`long_interval`
: The polling interval when `interval` returns success (default: 300).
`short_interval`
: The polling interval when `interval` returns failure (default: 30).
