Corrected a typo in the codepage number when detecting the default code page. #> <# .DESCRIPTION Contains a function to translate text using the DeepL API. More information about the DeepL API can be found here: https://www.deepl.com/de/docs-api/introduction/. To use this PowerShell function, a DeepL ApiKey is needed which requires an account. To register for an account, go to www.deepl.com. .LINK https://github.com/admins-little-helper/DeeplTranslate .LINK https://www.deepl.com .LINK https://www.deepl.com/de/docs-api/introduction/ #> function Invoke-DeeplTranslateText { <# .SYNOPSIS Translates text using the DeepL API. .DESCRIPTION The 'Invoke-DeeplTranslateText' function translates text using the DeepL API. To use the DeepL API, either a free or pro account is required. .PARAMETER TextToTranslate Text to be translated. Only UTF8-encoded plain text is supported. Supports pipeline input. .PARAMETER TargetLanguage The language the text should be translated to. .PARAMETER SourceLanguage Language of the text to be translated. If no source language is specified, the DeepL Api tries to automatically detect the language. .PARAMETER SplitSentences Sets whether the translation engine should first split the input into sentences. This is enabled by default ('On'). .PARAMETER PreserveFormatting Sets whether the translation engine should respect the original formatting, even if it would usually correct some aspects. This is disabled by default ('Off'). .PARAMETER Formality Sets whether the translated text should lean towards formal or informal language. .PARAMETER GlossaryId Specify the glossary to use for the translation. Important: This requires the SourceLanguage parameter to be set and the language pair of the glossary has to match the language pair of the request. .PARAMETER ApiKey API authentication key. You need an authentication key to access the DeepL API. Refer to the DeepL API documentation for more information. .EXAMPLE Invoke-DeeplTranslateText -TextToTranslate "PowerShell is cool!" -TargetLanguage "DE" -ApiKey "<MyApiKey>" This example shows how to translate a text into German. .EXAMPLE Invoke-DeeplTranslateText -TextToTranslate "PowerShell is cool!" -SourceLanguage "EN" -TargetLanguage "DE" -ApiKey "<MyApiKey>" SourceText : PowerShell is cool! TargetText : PowerShell ist cool! DetectedSourceLanguage : EN SpecifiedSourceLanguage : EN SpecifiedTargetLanguage : DE OriginalResponse : @{translations=System.Object[]} This example shows how to translate a text into German by also specifying the source language as beeing English. .INPUTS String for parameter 'TextToTranslate' .OUTPUTS PSCustomObject .NOTES Author: Dieter Koch Email: diko@admins-little-helper.de .LINK https://github.com/admins-little-helper/DeeplTranslate/blob/main/Help/Invoke-DeeplTranslateText.txt #> [CmdletBinding()] param ( [Parameter(Mandatory = $true, ValueFromPipeline)] [string[]] $TextToTranslate, [ValidateSet("Off", "On", "nonewlines")] [string] $SplitSentences, [ValidateSet("Off", "On")] [string] $PreserveFormatting, [ValidateSet("default", "more", "less", "prefer_more", "prefer_less")] [ValidateNotNullOrEmpty()] [string] $Formality, [Parameter(ValueFromPipeline)] [ValidateNotNullOrEmpty()] [System.Guid[]] $GlossaryId, [Parameter(Mandatory = $true)] [ValidateNotNullOrEmpty()] [string] $ApiKey ) # Use dynamic parameters for source and target language to either choose the language from a predefined static list. # or retrieve the list of supported languages from the DeepL Api.
