Question 2011 Scripting Games : Advanced Event 10

Bonsoir,

Ci-après le script que j'ai posté lors des Scripting Games 2011, dans le cadre de l'Advanced Event 10.

Il s'agissait du dernier évènement pour cette compétition (Snif !... Vivement l'année prochaine ! )

Le scénario était le suivant :

Event scenario

You find yourself frequently writing data to a text file. Often, you delete these text files later. You decide that an advanced function that will accept piped content to create a temporary text file would be useful. When added to a module or included in a profile, this function would always be available.

Design points

The function must be designed as an Advanced function, complete with comment-based Help.
The function must accept piped content.
The function should return the path to the temporary file.
The temporary file should have a temporary name, and it should reside in the temporary folder.
Design points for using an appropriate name for this function.
Additional points for adding a switch that will display the content of the temporary file in Notepad.
Additional points for supporting an encoding parameter and support ASCII and Unicode as encoding types.
Additional points for supporting the whatif, debug, and verbose parameters.
