.SYNOPSIS Creates a new TextBlock element for an Adaptive Card. .DESCRIPTION The New-CardTextBlock function creates a TextBlock element that displays text content in an Adaptive Card. TextBlocks support various formatting options including size, weight, color, and text wrapping. They are fundamental building blocks for displaying textual information in Adaptive Cards. .PARAMETER Text The text content to display in the TextBlock. Supports plain text and Markdown formatting depending on the host application's capabilities. .PARAMETER Size The size of the text. Common values include: - Default: Standard text size - Small: Smaller than default - Medium: Medium size text - Large: Large text - ExtraLarge: Extra large text Default value is "Default". .PARAMETER Weight The weight (boldness) of the text. Common values include: - Default: Normal text weight - Lighter: Lighter than normal - Bolder: Bold text Default value is "Default". .PARAMETER Color The color scheme to apply to the text. Valid values are: - Default: Default text color - Dark: Dark text color - Light: Light text color - Accent: Accent color (typically blue) - Good: Success/positive color (typically green) - Warning: Warning color (typically orange/yellow) - Attention: Attention/error color (typically red) Default value is "Default". .PARAMETER Id An optional unique identifier for the TextBlock element. Useful for referencing the element in actions like toggle visibility or for accessibility purposes. .PARAMETER Wrap A switch parameter that enables text wrapping. When specified, long text will wrap to multiple lines instead of being truncated. Without this parameter, text may be clipped if it exceeds the available width. .OUTPUTS System.Collections.Hashtable Returns a hashtable representing the TextBlock element structure for the Adaptive Card. .EXAMPLE New-CardTextBlock -Text "Welcome to our application!" -Size "Large" -Weight "Bolder" Creates a large, bold welcome message. .EXAMPLE New-CardTextBlock -Text "⚠️ This is a warning message" -Color "Warning" -Wrap Creates a warning-colored text block with wrapping enabled and an emoji icon. .EXAMPLE New-CardTextBlock -Text "Status: System is operational" -Color "Good" -Id "StatusText" Creates a success-colored status message with an ID for potential reference in actions. .EXAMPLE New-CardTextBlock -Text "This is a very long text that should wrap to multiple lines when displayed" -Wrap Creates a text block with wrapping enabled for long content. .NOTES - The Size and Weight parameters accept string values that correspond to Adaptive Card schema values - Color values map to the host application's theme colors - The Wrap parameter is essential for longer text content to ensure readability - Markdown formatting support depends on the host application (Teams, Outlook, etc.) - The Id parameter is optional but recommended when the text needs to be referenced by actions .LINK https://docs.microsoft.com/en-us/adaptive-cards/authoring-cards/card-schema#textblock #> function New-CardTextBlock { param ( [string] $Text, [string] $Size = "Default", [string] $Weight = "Default", [string] [ValidateSet("Default", "Dark", "Light", "Accent", "Good", "Warning", "Attention")] $Color = "Default", [string] [Parameter(Mandatory = $false)] $Id, [switch] $Wrap ) $TextBlock = @{ type = "TextBlock" text = $Text size = $Size weight = $Weight color = $Color } if ($Id) { $TextBlock.id = $Id } if ($Wrap) { $TextBlock.wrap = $true } Return ($TextBlock) } |
