.SYNOPSIS Creates a new temporary directory with an optional name prefix. .DESCRIPTION The New-TemporaryDirectory function creates a uniquely named temporary directory under the system temp path or a specified base path. The directory name is composed of the given prefix followed by the first 8 characters of a new GUID, ensuring uniqueness. The function returns the DirectoryInfo object for the created directory. .PARAMETER Prefix A prefix string for the temporary directory name. Defaults to 'tcs'. The final directory name follows the pattern '{Prefix}_{first8-guid-chars}'. .PARAMETER BasePath An optional base directory path under which the temporary directory is created. Defaults to the system temporary path returned by [System.IO.Path]::GetTempPath(). .INPUTS None This function does not accept pipeline input. .OUTPUTS System.IO.DirectoryInfo Returns the DirectoryInfo object representing the newly created temporary directory. .EXAMPLE New-TemporaryDirectory Creates a directory like 'C:\Users\<user>\AppData\Local\Temp\tcs_a1b2c3d4' and returns its DirectoryInfo object. .EXAMPLE New-TemporaryDirectory -Prefix "build" -BasePath "D:\Staging" Creates a directory like 'D:\Staging\build_e5f6a7b8' and returns its DirectoryInfo object. .EXAMPLE $tmpDir = New-TemporaryDirectory -Prefix "test" Set-Location $tmpDir.FullName Creates a temporary directory with a 'test' prefix and changes to it. .NOTES Author: Nigel Tatschner Company: TheCodeSaiyan Version: 0.2.0 This function is part of the tcs.core module and provides a convenient way to create uniquely named temporary directories for build artifacts, test isolation, or other transient file operations. .LINK https://ntatschner.github.io/TheCodeSaiyan-PowerShell-tcs.core/ #> function New-TemporaryDirectory { [CmdletBinding()] [OutputType([System.IO.DirectoryInfo])] param( [Parameter(HelpMessage = "Prefix string for the temporary directory name.")] [string]$Prefix = 'tcs', [Parameter(HelpMessage = "Base directory path for the temporary directory.")] [string]$BasePath ) if ([string]::IsNullOrWhiteSpace($BasePath)) { $BasePath = [System.IO.Path]::GetTempPath() } $guidSegment = (New-Guid).ToString('N').Substring(0, 8) $directoryName = "${Prefix}_${guidSegment}" $fullPath = Join-Path -Path $BasePath -ChildPath $directoryName $directory = New-Item -Path $fullPath -ItemType Directory -Force return $directory } |
