# Powershell Wrapper for Voicemeeter API

This module offers a Powershell interface for the Voicemeeter Remote C API.

For past/future changes to this project refer to: [CHANGELOG](CHANGELOG.md)

## Tested against

- Basic 1.0.8.8
- Banana 2.0.6.8
- Potato 3.0.2.8

## Requirements

- [Voicemeeter](https://voicemeeter.com/)
- Powershell 5.1+ or Powershell 7.2+

## Installation

#### PowerShellGet:

In Powershell as admin:

`Install-Module Voicemeeter`

In Powershell as current user:

`Install-Module -Name Voicemeeter -Scope CurrentUser`

You may be asked to install NuGet provider required by PowerShellGet if you don't have it already.

When prompted you will need to accept PSGallery as a trusted repository.

More Info:

- [PowerShellGet](https://docs.microsoft.com/en-us/powershell/scripting/gallery/installing-psget?view=powershell-7.1)
- [NuGet](https://www.powershellgallery.com/packages/NuGet/1.3.3)
- [PSGallery](https://docs.microsoft.com/en-gb/powershell/scripting/gallery/overview?view=powershell-7.1)

#### Direct download:

`git clone https://github.com/onyx-and-iris/voicemeeter-api-powershell.git`

All examples in this readme assume you've installed as a module.
If you decide to direct download see [alternative instructions](FROM_SOURCE.md).

## Use

#### `Script files`

When you instantiate Remote class you will automatically be logged in. Use a
try finally block to ensure you logout at the end of your code.

```powershell
Import-Module Voicemeeter

try {
    # Run the factory function for required Voicemeeter type
    $vmr = Get-RemoteBanana

    # Set strip and bus params
    $vmr.strip[0].mono = $true
    $vmr.strip[0].mono  '=> $true'
    $vmr.bus[1].mute = $false
    $vmr.bus[1].mute    '=> $false'

    # Set macrobutton with id 4, mode state to 1
    $vmr.button[4].state = $true
    $vmr.button[4].state    '=> $true'
}
finally { $vmr.Logout() }
```

Voicemeeter factory function can be:

- Get-RemoteBasic
- Get-RemoteBanana
- Get-RemotePotato

Added in `v3` you may also use the following entry/exit points:

- Connect-Voicemeeter
- Disconnect-Voicemeeter

`Connect-Voicemeeter` takes a single parameter `Kind`.

for example:

```powershell
$vmr = Connect-Voicemeeter -Kind "potato"
...
Disconnect-Voicemeeter
```

#### `Through the Shell`

One liners should be run through a subshell, you may pipe the Remote object to a script block, for example:

```powershell
powershell { Get-RemoteBanana | % { $_.strip[0].mute=$true; $_.Logout() } }
```

You may also save the object returned by a factory function to a local variable, then invoke any commands through the shell, for example:

```powershell
$vmr = Get-RemoteBanana
$vmr.strip[0].mute=1
$vmr.strip[0].mute
$vmr.Logout()
```

### VBAN

- vmr.vban.enable: Toggle VBAN on or off. Accepts a bool value.

For each vban in/out stream the following parameters are defined:

$vmr.vban.enable = $true

$vmr.vban.instream[0].on = $true
$vmr.vban.instream[2].port = 6990

### Multiple parameters

Set many strip/bus/macrobutton/vban parameters at once, for Example

```powershell
Import-Module Voicemeeter

try {
    $vmr = Get-RemoteBanana

    $hash = @{
        strip_0 = @{mute = $true; mono = $true};
        strip_2 = @{mute = $true; mono = $true};
        bus_1 = @{mute = $true; mono = $true};

        button_34 = @{state = $true};
        button_12 = @{trigger = $false};

        vban_instream_3 = @{name = 'streamname'};
        vban_outstream_0 = @{on = $false};
    }

    $vmr.Set_Multi($hash)
}
finally { $vmr.Logout() }
```

### Config Files

`$vmr.Set_Profile(<configname>)`

You may load config files in psd1 format. An example profile has been included with the package. Remember to save current settings before loading a profile. To test simply rename \_profiles directory to profiles. It will be loaded into memory but not set. To set one you may do:

```powershell
Import-Module Voicemeeter
try {
    $vmr = Get-RemoteBanana
    $vmr.Set_Profile("config")
}
finally { $vmr.Logout() }
```

will load a config file at profiles/banana/config.psd1 for Voicemeeter Banana.

### Remote class

Access to lower level Getters and Setters are provided with these functions:

- `$vmr.Getter(param)`: For getting the value of a parameter expected to return a value other than string.
- `$vmr.Getter_String(param)`: For getting the value of any parameter expected to return a string.
- `$vmr.Setter(param, value)`: For setting the value of any parameter.

```powershell
$vmr.Getter('Strip[2].Mute')
$vmr.Getter_String('Bus[1].Label')
$vmr.Setter('Strip[4].Label', 'stripname')
$vmr.Setter('Strip[0].Gain', -3.6)
```

- `$vmr.SendText`: Set parameters by script

```powershell
 $vmr.SendText("strip[0].mute=1;strip[2].gain=3.8;bus[1].eq.On=1")
```

Access to lower level polling functions are provided with these functions:

- `$vmr.PDirty`: Returns true if a parameter has been updated.
- `$vmr.MDirty`: Returns true if a macrobutton has been updated.

### Errors

- `VMRemoteError`: Base custom error class.
- `LoginError`: Raised when a login error occurs.
- `CAPIError`: Raised when a C-API function returns an error code.
  - The following class properties are available:
    - `function`: The name of the C-API function that returned the error code.
    - `code`: The error code.

### Run tests

Run tests using .\tests\pre-commit.ps1 which accepts the following parameters:

- `kind`: Run tests of this kind
- `tag`: Run tests tagged with this marker (currently `higher` or `lower`)
- `num`: Run this number of tests
- `log`: Write summary log file

Run tests from repository root in a subshell and write logs, like so:

`powershell .\tests\pre-commit.ps1 -k "potato" -t "higher" -log`
