在emacs中围绕选择包装文本

Question

I would like to wrap some text around selected text in emacs.

From a selection of the lines:

First item
Second item

I would like to get :

\begin{itemize}
\item First item
\item Second item
\end{itemize}

Using Cc Ce in AucTeX collapses the selection into one line:

\begin{itemize}
\item First item Second item
\end{itemize}

The following snippet in yasnippet:

# -*- mode: snippet -*-
# name : wrap item
# expand-env : ((yas-wrap-around-region nil) (item-string "\item  "))
# binding : C-M-z
# --
\begin{itemize}
`(let ((text (yas-selected-text))) (when text (replace-regexp-in-string "^" item-string text)))` $0
\end{itemize}

gives:

\begin{itemize}
item First item
item Second item
\end{itemize}

I tried using (item-string "\\\\item ") instead, but that gives the error:

[yas] elisp error: Invalid use of '\\' in replacement text

I would like to have the snippet work as I can modify it for use in other contexts also.

I just wrote some starter code to solve this problem in a general way. It's at https://github.com/abo-abo/latex-wrap . It already works for the specific case that you describe, and you can help me extend it by posting issues .
