You may also run this script directly from the web using the following command: ```powershell & ([scriptblock]::Create((iwr 'https://bit.ly/ps-nerdfont-installer'))) ``` Parameters may be passed at the end just like any other PowerShell script. .DESCRIPTION An interactive installer for Nerd Fonts and Cascadia Code on Windows, macOS, or Linux. The script downloads the font archive from the GitHub release pages and extracts the font files to the user's font directory, or the system font directory when using the AllUsers scope with elevated permissions. Besides installing the script locally, you may also run this script directly from the web using the following command: ```powershell & ([scriptblock]::Create((iwr 'https://bit.ly/ps-nerdfont-installer'))) # Or alternatively without the shortened URL & ([scriptblock]::Create((iwr 'https://raw.githubusercontent.com/jpawlowski/devcontainer-features/main/src/powershell-extended/Invoke-NerdFontInstaller.ps1'))) ``` > **IMPORTANT**: A code signature cannot be verified when running the script directly from the web. > SSL transport layer encryption is used to protect the script during download from GitHub and during > redirection from the URL shortener. Parameters may be passed just like any other PowerShell script. For example: ```powershell & ([scriptblock]::Create((iwr 'https://bit.ly/ps-nerdfont-installer'))) -Name cascadia-code, cascadia-mono ``` To get a lest of available Nerd Fonts, use the following command: ```powershell & ([scriptblock]::Create((iwr 'https://bit.ly/ps-nerdfont-installer'))) -List All ``` .PARAMETER Name The name of the Nerd Font to install. Multiple font names can be specified as an array of strings. If no font name is specified, the script provides an interactive menu to select the font to install (unless the All parameter is used). The menu is displayed only if the script is run in an interactive environment. If the script is run in a non-interactive environment, the Name parameter is mandatory. Possible font names are dynamically retrieved from the Nerd Font library on GitHub. .PARAMETER Variant Specify the font variant to install. The default value is 'Variable'. A variable font is a single font file that can contain multiple variations of a typeface while a static font is a traditional font file with a single style. For example, a variable font can contain multiple weights and styles in a single file. Most Nerd Fonts are only available as static fonts. The only exception today is Microsoft's Cascadia Code font where variable fonts are recommended to be used for all platforms. Setting this parameter to 'Static' will search for a folder with the name 'static' in the font archive. If that was found, files from that folder will be installed, otherwise, the script will install the font files from the root of the archive (or the folder for the font type, if any is found). .PARAMETER Type Specify the order to search for font types. Only the first matching type will be installed. The default order is TTF, OTF, WOFF2. The script will search for folders with the specified type name in the font archive, and if found, install the fonts from that folder. If no folder is found, the script will install the font files from the root of the archive. The script will search for files with the specified type extension in any case. .PARAMETER All Install all available Nerd Fonts. You will be prompted to confirm the installation for each font with the option to skip, cancel, or install all without further confirmation. .PARAMETER List List available Nerd Fonts matching the specified pattern. Use '*' or 'All' to list all available Nerd Fonts. This parameter does not install any fonts. .PARAMETER Scope Defined the scope in which the Nerd Font should be installed. The default value is CurrentUser. The AllUsers scope requires elevated permissions. The CurrentUser scope installs the font for the current user only. .PARAMETER Force Overwrite existing font files instead of skipping them. .EXAMPLE Invoke-NerdFontInstaller -Name cascadia-code Install the Cascadia Code fonts from the Microsoft repository. .EXAMPLE Invoke-NerdFontInstaller -Name cascadia-mono Install the Cascadia Mono fonts from the Microsoft repository. .EXAMPLE Invoke-NerdFontInstaller -Name cascadia-code, cascadia-mono Install the Cascadia Code and Cascadia Mono fonts from the Microsoft repository. .EXAMPLE Invoke-NerdFontInstaller -All -WhatIf Show what would happen if all fonts were installed. .EXAMPLE Invoke-NerdFontInstaller -List cascadia* List all fonts with names starting with 'cascadia'. .NOTES This script must be run on your local machine, not in a container. #> [CmdletBinding(DefaultParameterSetName = 'ByName', SupportsShouldProcess, ConfirmImpact = 'High')] param( [Parameter(Mandatory = $false, ParameterSetName = 'ByAll', HelpMessage = 'Which Font variant do you prefer?')] [Parameter(Mandatory = $false, ParameterSetName = 'ByName', HelpMessage = 'Which Font variant do you prefer?')] [ArgumentCompleter({ param($commandName, $parameterName, $wordToComplete, $commandAst, $fakeBoundParameter) @('Variable', 'Static') | Where-Object { $_ -like "$wordToComplete*" } | ForEach-Object { [System.Management.Automation.CompletionResult]::new($_, $_, 'ParameterValue', $_) } })] [ValidateSet('Variable', 'Static')] [string]$Variant = 'Variable', [Parameter(Mandatory = $false, ParameterSetName = 'ByAll', HelpMessage = 'Specify the order to search for font types.
