---

## `Use`

`go get github.com/onyx-and-iris/vbantxt`

```go
package main

import (
	"log"

	"github.com/onyx-and-iris/vbantxt"
)

func main() {
	var (
		host       string = "vm.local"
		port       int    = 6980
		streamname string = "onyx"
	)

	client, err := vbantxt.New(host, port, streamname)
	if err != nil {
		log.Fatal(err)
	}
	defer client.Close()

	err = client.Send("strip[0].mute=0")
	if err != nil {
		_, _ = fmt.Fprintf(os.Stderr, "Error: %s", err)
		os.Exit(1)
	}
}
```

## `Command Line`

Pass `host`, `port` and `streamname` as flags, for example:

```
vbantxt -h="gamepc.local" -p=6980 -s=Command1 "strip[0].mute=1 strip[1].mono=1"
```

You may also store them in a `config.toml` located in `home directory / .config / vbantxt /`

A valid `config.toml` might look like this:

```toml
[connection]
host="gamepc.local"
port=6980
streamname="Command1"
```

-   `host` defaults to "localhost"
-   `port` defaults to 6980
-   `streamname` defaults to "Command1"

Command line flags will override values in a config.toml.

---

## `Script files`

The vbantxt CLI accepts a single string request or an array of string requests. This means you can pass scripts stored in files.

For example, in Windows with Powershell you could:

`vbantxt $(Get-Content .\script.txt)`

Or with Bash:

`xargs vbantxt < script.txt`

to load commands from a file:

```
strip[0].mute=1;strip[0].mono=0
strip[1].mute=0;strip[1].mono=1
bus[3].eq.On=0
```

---

## `Matrix`

Sending commands to VB-Audio Matrix is also possible, for example:

```
vbantxt -s=streamname "Point(ASIO128.IN[2],ASIO128.OUT[1]).dBGain = -8"
```

---

## `Logging`

The `-log-level` flag allows you to control the verbosity of the application's logging output. 

Acceptable values for this flag are:

- `trace`
- `debug`
- `info`
- `warn`
- `error`
- `fatal`
- `panic`

For example, to set the log level to `debug`, you can use:

```
vbantxt -s=streamname -log-level=debug "bus[0].eq.on=1 bus[1].gain=-12.8"
```

The default log level is `warn` if the flag is not specified.
