# Voicemeeter Remote Command Line Utility

## `Tested against`

- Basic 1.1.1.1
- Banana 2.1.1.1
- Potato 3.1.1.1

## `Requirements`

- [Voicemeeter](https://voicemeeter.com/)

## `Use`

```powershell
./vmrcli.exe [-h] [-i] [-k] [-D] [-v] [-p] [-m] [-s] <api commands>
```

Where:

- `h`: Prints the help message.
- `i`: Enable interactive mode. If set, any api commands passed on the command line will be ignored.
- `k`: The kind of Voicemeeter (basic, banana or potato). Use this to launch the GUI.
- `D`: Set log level 0=TRACE, 1=DEBUG, 2=INFO, 3=WARN, 4=ERROR, 5=FATAL
- `v`: Enable extra console output (toggle, set messages)
- `p`: Load a user configuration (given the file name or a full path)
- `m`: Launch the MacroButtons application
- `s`: Launch the StreamerView application

## `API Commands`

- Commands starting with `!` will be toggled, use it with boolean parameters.
- Commands containing `=` will set a value. (use `+=` and `-=` to increment/decrement)
- All other commands with get a value.

Examples:

Launch basic GUI, set log level to INFO, Toggle Strip 0 Mute, print its new value, then decrease Bus 0 Gain by 3.8

```powershell
./vmrcli.exe -kbasic -D2 !strip[0].mute strip[0].mute bus[0].gain-=3.8
```

Launch banana GUI, set log level to DEBUG, set Strip 0 label to podmic then print Strip 2 label

```powershell
./vmrcli.exe -kbanana -D1 strip[0].label=podmic strip[2].label
```

## `Interactive Mode`

Running the following command in Powershell:

```powershell
./vmrcli.exe -i
```

Will open an interactive prompt:

```powershell
Interactive mode enabled. Enter 'Q' to exit.
>>
```

API commands follow the same rules as listed above. Entering `Q` or `q` will exit the program.

## `Script files`

Scripts can be loaded from text files, for example in Powershell:

```powershell
./vmrcli.exe -D1 $(Get-Content .\example_commands.txt)
```

Multiple API commands can be in a single line but they should be space separated.

## `Build`

Run the included `makefile` with [GNU Make](https://www.gnu.org/software/make/).

The binary in [Releases][releases] is compiled with coloured logging enabled. To disable this you can override the `LOG_USE_COLOR` variable, for example:

`make LOG_USE_COLOR=no`
