Emacs function: [pre] marked region [post]

Question

Selecting region, how to get a (pre)defined part before and after region?

Let's say for instance, working with LaTeX, we want \begin{frame}{} before the region and \end{frame} after region, how to get this done with Emacs by one function?

    [pre-part]"Has to be around this"[post-part] 

I would encourage use of yasnippet. Also, maybe "autopare" can give a hint, since somehow it smartly can put quote signs around the marked region when pressing ".

Answer 1

You can use yasnippet. Here is an example for an html tag snippet that can wrap or not.

# -*- mode: snippet -*-
# name: Wrap open close tags
# binding: C-c C-t
# expand-env: ((yas-wrap-around-region t))
# --
<$1>$0</${1:$(car (split-string text))}>

This works with the latest github version of yasnippet.

Answer 2

In latex-mode, C-c C-o does just that.
