Why Enable Autocompletion in PowerShell?

Autocompletion in PowerShell enhances your command-line efficiency by:

• Reducing Typing Effort: Quickly complete commands without typing them out fully.
• Minimizing Errors: Avoid typos and syntax errors by using the suggested completions.
• Speeding Up Workflow: Navigate through available commands and parameters swiftly.

Step-by-Step Guide to Enable Autocompletion

Step 1: Install PSReadLine Module

The PSReadLine module is crucial for enabling autocompletion and enhancing the overall command-line experience in PowerShell. Here’s how to install it:

1. Open PowerShell as Administrator: Right-click the Start button and select “Windows PowerShell (Admin)” or “PowerShell (Admin)”.

2. Run the Install-Module Command: Execute the following command to install the PSReadLine module:

    Install-Module PSReadLine -AllowPrerelease -Force
   

   • Install-Module: This cmdlet installs the specified module.
   • PSReadLine: The module name.
   • -AllowPrerelease: This flag ensures you get the latest pre-release version, which might include new features and fixes.
   • -Force: This parameter forces the installation, overriding any prompts for user confirmation.
3. Verify Installation: Check if the module is installed correctly by running:

    Get-Module -ListAvailable PSReadLine
   

Step 2: Install PowerShellGet Module

PowerShellGet is a module that provides cmdlets for discovering, installing, updating, and publishing PowerShell artifacts like modules and scripts.

1. Run the Install-Module Command: Execute the following command to install the PowerShellGet module:

    Install-Module -Name PowerShellGet -Force
   

   • Install-Module: This cmdlet installs the specified module.
   • -Name PowerShellGet: Specifies the module name.
   • -Force: This parameter forces the installation, overriding any prompts for user confirmation.
2. Verify Installation: Ensure the module is installed by running:

    Get-Module -ListAvailable PowerShellGet
   

Step 3: Restart PowerShell

After installing the necessary modules, restart PowerShell to apply the changes. This ensures that the autocompletion features provided by PSReadLine are fully activated.

Step 4: Customize Autocompletion (Optional)

PSReadLine offers customization options to enhance your autocompletion experience:

• Edit Key Bindings: Customize key bindings to suit your preferences using:

    Set-PSReadLineKeyHandler -Key Tab -Function Complete
  

• Configure Colors: Change the color scheme for autocompletion suggestions:

    Set-PSReadLineOption -Colors @{
     "Selection" = [ConsoleColor]::Yellow;
     "Emphasis" = [ConsoleColor]::Gray;
     "InlinePrediction" = [ConsoleColor]::DarkBlue
     }
  

• Restore back to Default color scheme for autocompletion suggestions

  Set-PSReadLineOption -Colors @{
     "Selection" = [ConsoleColor]::Black;
     "Emphasis" = [ConsoleColor]::Cyan;
     "InlinePrediction" = [ConsoleColor]::DarkGray
     }
