function Uninstall-WhiskeyTool { <# .SYNOPSIS Removes a tool installed with `Install-WhiskeyTool`. .DESCRIPTION The `Uninstall-WhiskeyTool` function removes tools that were installed with `Install-WhiskeyTool`. It removes PowerShell modules, NuGet packages, Node, Node modules, and .NET Core SDKs that Whiskey installs into your build root. PowerShell modules are removed from the `Modules` direcory. NuGet packages are removed from the `packages` directory. Node and node modules are removed from the `.node` directory. The .NET Core SDK is removed from the `.dotnet` directory. When uninstalling a Node module, its name should be prefixed with `NodeModule::`, e.g. `NodeModule::rimraf`. Users of the `Whiskey` API typcially won't need to use this function. It is called by other `Whiskey` function so they have the tools they need. .EXAMPLE Uninstall-WhiskeyTool -ModuleName 'Pester' Demonstrates how to remove the `Pester` module from the default location. .EXAMPLE Uninstall-WhiskeyTool -NugetPackageName 'NUnit.Runners' -Version '2.6.4' Demonstrates how to uninstall a specific NuGet Package. In this case, NUnit Runners version 2.6.4 would be removed from the default location. .EXAMPLE Uninstall-WhiskeyTool -ModuleName 'Pester' -Path $forPath Demonstrates how to remove a Pester module from a specified path location other than the default location. In this case, Pester would be removed from the directory pointed to by the $forPath variable. .EXAMPLE Uninstall-WhiskeyTool -ModuleName 'Pester' -DownloadRoot $Root Demonstrates how to remove a Pester module from a DownloadRoot. In this case, Pester would be removed from `$Root\Modules`. .EXAMPLE Uninstall-WhiskeyTool -Name 'Node' -InstallRoot $TaskContext.BuildRoot Demonstrates how to uninstall Node from the `.node` directory in your build root. .EXAMPLE Uninstall-WhiskeyTool -Name 'NodeModule::rimraf' -InstallRoot $TaskContext.BuildRoot Demonstrates how to uninstall the `rimraf` Node module from the `node_modules` directory in the Node directory in your build root. .EXAMPLE Uninstall-WhiskeyTool -Name 'DotNet' -InstallRoot $TaskContext.BuildRoot Demonstrates how to uninstall the .NET Core SDK from the `.dotnet` directory in your build root. #> [CmdletBinding()] param( [Parameter(Mandatory=$true,ParameterSetName='Tool')] [string] # The name of the tool to uninstall.
