function Install-WhiskeyTool { <# .SYNOPSIS Downloads and installs tools needed by the Whiskey module. .DESCRIPTION The `Install-WhiskeyTool` function downloads and installs PowerShell modules or NuGet Packages needed by functions in the Whiskey module. PowerShell modules are installed to a `Modules` directory in your build root. A `DirectoryInfo` object for the downloaded tool's directory is returned. `Install-WhiskeyTool` also installs tools that are needed by tasks. Tasks define the tools they need with a [Whiskey.RequiresTool()] attribute in the tasks function. Supported tools are 'Node', 'NodeModule', and 'DotNet'. Users of the `Whiskey` API typcially won't need to use this function. It is called by other `Whiskey` function so they ahve the tools they need. .EXAMPLE Install-WhiskeyTool -ModuleName 'Pester' Demonstrates how to install the most recent version of the `Pester` module. .EXAMPLE Install-WhiskeyTool -ModuleName 'Pester' -Version 3 Demonstrates how to instals the most recent version of a specific major version of a module. In this case, Pester version 3.6.4 would be installed (which is the most recent 3.x version of Pester as of this writing). .EXAMPLE Install-WhiskeyTool -NugetPackageName 'NUnit.Runners' -version '2.6.4' Demonstrates how to install a specific version of a NuGet Package. In this case, NUnit Runners version 2.6.4 would be installed. #> [CmdletBinding()] param( [Parameter(Mandatory=$true,ParameterSetName='Tool')] [Whiskey.RequiresToolAttribute] # The attribute that defines what tool is necessary. $ToolInfo, [Parameter(Mandatory=$true,ParameterSetName='Tool')] [string] # The directory where you want the tools installed. $InstallRoot, [Parameter(Mandatory=$true,ParameterSetName='Tool')] [hashtable] # The task parameters for the currently running task. $TaskParameter, [Parameter(ParameterSetName='Tool')] [Switch] # Running in clean mode, so don't install the tool if it isn't installed. $InCleanMode, [Parameter(Mandatory=$true,ParameterSetName='PowerShell')] [string] # The name of the PowerShell module to download. $ModuleName, [Parameter(Mandatory=$true,ParameterSetName='NuGet')] [string] # The name of the NuGet package to download. $NuGetPackageName, [Parameter(ParameterSetName='NuGet')] [Parameter(ParameterSetName='PowerShell')] [string] # The version of the package to download.
