PSMenu

Simple module to generate interactive console menus (like yeoman)

Examples

Very basic example.

Show-Menu @("option 1", "option 2", "option 3")

Custom formatting

Custom formatting of menu items and multi-selection:

Show-Menu -MenuItems $(Get-NetAdapter) -MultiSelect -MenuItemFormatter { $Args | Select -Exp Name }

Custom options

You can also use custom options (enriched options). A more complicated example:

class MyMenuOption {
    [String]$DisplayName
    [ScriptBlock]$Script

    [String]ToString() {
        Return $This.DisplayName
    }
}

function New-MenuItem([String]$DisplayName, [ScriptBlock]$Script) {
    $MenuItem = [MyMenuOption]::new()
    $MenuItem.DisplayName = $DisplayName
    $MenuItem.Script = $Script
    Return $MenuItem
}

$Opts = @(
    $(New-MenuItem -DisplayName "Say Hello" -Script { Write-Host "Hello!" }),
    $(New-MenuItem -DisplayName "Say Bye!" -Script { Write-Host "Bye!" })
)

$Chosen = Show-Menu -MenuItems $Opts

& $Chosen.Script

This will show the menu items like you expect.

Separators

Show-Menu @("Option A", "Option B", $(Get-MenuSeparator), "Quit")

Separators are unselectable items used for visual distinction in the menu.

Callback

The Callback option can be used to perform actions while the menu is displayed. Note: always save & restore the cursor position like in the following example if the host output is changed in the callback.

Clear-Host
Write-Host "Current time: $(Get-Date)"
Write-Host ""
Show-Menu @("Option A", "Option B") -Callback {
    $lastTop = [Console]::CursorTop
    [System.Console]::SetCursorPosition(0, 0)
    Write-Host "Current time: $(Get-Date)"
    [System.Console]::SetCursorPosition(0, $lastTop)
}
