Write your [Home Assistant](https://www.home-assistant.io/) automations with a strongly-typed Golang library!
## Why?
My Home Assistant automation journey started with [Node-RED](https://nodered.org/). Since I already know how to write javascript, I started stuffing all my logic into code nodes in Node-RED.
Then one day I stumbled on [Appdaemon](https://appdaemon.readthedocs.io/en/latest/), which lets you write automations entirely in Python. I switched all my automations over because of the flexibility I gained from writing my automations in code.
While autocomplete in your IDE seems trivial, it's an important feature many developers take for granted. Python isn't great at it.
I wanted to learn Golang, and had the idea to wrap the Home Assistant websocket API with a Go library. Go's strong typing means I don't have to remember the API because my IDE will fill in the blanks for me. So anyway, here's my first Go project, I hope you find it useful 😁
## Quick Start

### Write your automations
Check out `example/example.go` for an example of the 3 types of automations — schedules, entity listeners, and event listeners. Instead of copying and pasting, try typing it our yourself to see how autocomplete guides you through the setup using a builder pattern. You can also check out some of the other options you see in the autocomplete.

### Run your code
Keeping with the simplicity that Go is famous for, you don't need a whole environment or docker container to run Gome-Assistant. It's just a binary like any other Go code you would write. So once you have your automations, you can run it however you like — using `screen` or `tmux`, a cron job, or wrap it up in a docker container if you just can't get enough docker!

## Disclaimer
Gome-Assistant is a new library, and I'm opening it up early to get some user feedback on the API and help shape the direction. I plan for it to grow to cover all Home Assistant use cases, services, and event types. So it's possible — maybe likely — that breaking changes will happen before v1.0.0!
## API Reference (TODO)
## gome-assistant Concepts (TODO)
First, you'll need to create your app.
```go
import ga "github.com/saml-dev/gome-assistant"
// replace with IP and port of your Home Assistant installation if needed
app := ga.App("0.0.0.0:8123")
```
A full reference is available on [pkg.go.dev](https://pkg.go.dev/github.com/saml-dev/gome-assistant), but all you need to know to get started are the three types of automations in gome-assistant.
### Schedules
Schedules are as you expect, a way to run a function on a schedule. The most common schedule will be once a day.
```go
_7pm := ga.NewSchedule().Call(myFunc).Daily().At("19:00").Build()
```
Schedules can also be run at sunrise or sunset, with an optional [offset](https://pkg.go.dev/time#ParseDuration).
```go
// 30 mins before sunrise
sunrise := ga.NewSchedule().Call(myFunc).Daily().Sunrise(app, "-30m").Build()
```
Schedules are also used to run a function on a certain interval. Offset is used to offset the first run of a schedule from midnight.
```go
// run every hour at the 30-minute mark
interval := ga.NewSchedule().Call(a).Every("1h").Offset("30m").Build()
```
All schedules must be registered with your app. This will panic if there are any issues with the schedule.
```go
app.RegisterSchedules(_7pm, sunrise, interval)
```
#### Schedule Callback function
The function passed to `.Call()` must take
- `*ga.Service` used to call home assistant services
- `*ga.State` used to retrieve state from home assistant
