ISE - Snippets Variant 2

Hello again

poetter postet some ISE Custom menue extensions at poshcode.

He displays a list and uses a prompt dialog to select the choice.

Well the list might get quite long and I tried a different approach: selecting the choice by either the selected text or by the text left to the cursor. Here the result, which is based on his code.

#requires -version 2.0
## ISE-Snippets module v 1.0
## DEVELOPED FOR CTP3 
## See comments for each function for changes ...
##############################################################################################################
## As a shortcut for every snippet would be to much, I created Add-Snippet which presents a menu.
## Feel free to add your own snippets to function Add-Snippet but please contribute your changes here
##############################################################################################################
## Provides Code Snippets for working with ISE
## Add-Snippet - Presents menu for snippet selection
## Add-SnippetToEditor - Adds a snippet at caret position

Thanks and congratulation to Dmitry for delivering the new CTP 3 compatible Powergui version and telling in his blog about export html. I just tried this here for the code above.

The above code is ready for every days use. It is just a design study in programming the selection. Personally I don't use snippets in any editor while coding, just a question of personal taste.

In the long term I will use this to interactivly transform T-SQL into PL/SQL. I guess in the end, this will save a lot of my time.

Thanks to the PowerShell Team who did such a good and extendable job. A real christmas present.

Enjoy extending

Bernd
