`Command Line`

Configuration

Flags

--host/-H: defaults to localhost
--port/-p: defaults to 6980
--streamname/-s: defaults to Command1
--config/-C: defaults to $XDG_CONFIG_HOME / vbantxt / config.toml
--loglevel/-l: defaults to warn
--version/-v: print the vbantxt version and exit

For example:

vbantxt --host="gamepc.local" --port=6980 --streamname=Command1 "strip[0].mute=1 strip[1].mono=1"

Environment Variables

Load the following values from your environment:

#!/usr/bin/env bash

export VBANTXT_HOST=localhost
export VBANTXT_PORT=6980
export VBANTXT_STREAMNAME=onyx

Flags will override environment variables.

TOML Config

By default the config loader will look for a config in:

$XDG_CONFIG_HOME / vbantxt / config.toml (see os.UserConfigDir)

A valid config.toml might look like this:

host="gamepc.local"
port=6980
streamname="Command1"

A custom config path may be passed with the --config/-C flag.

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

`Logging`

The --loglevel/-l flag allows you to control the verbosity of the application's logging output.

Acceptable values for this flag are:

debug
info
warn
error
fatal
panic

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

vbantxt --loglevel=debug "bus[0].eq.on=1 bus[1].gain=-12.8"

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