surround selection with environment

[Biel Cardona]

Hi!

Is there a way to write a script that surrounds the current selection with a \begin{environment}..\end{environment}?

That is, if the text I have is

Line1
Line2
Line3
Line4
Line5

And the second line is selected, after execution of the script I get

Line1
\begin{environment}
Line2
\end{environment}
Line3
Line4
Line5

With "environment" being a placeholder to insert the environment name.

I have tried to write this script but no luck so far. The closest I have been to getting it to work is:

%SCRIPT
txt = cursor.selectedText()
editor.cut()
editor.insertSnippet("\begin{%<environment%:id:1%>}\n"+txt+"\n\end{%<%:mirror,id:1%>}\n")</environment%:id:1%>

It kinda works, but the inserted text overwrites the text after the selection; i.e, I get:
Line1
\begin{environment}
Line2

\end{environmente4
Line5

Quite strange, isn't it?

Thanks in advance!
