So, just sat down to look again at using Django templates with the google app-engine and now using my *new* text-editor of choice vim, I thought I would invest some time in improving the experience. I got told of a plug-in a couple of months ago which made creating html mark-up, simply like magic, and the plugin I mean is called surround.vim : http://www.vim.org/scripts/script.php?script_id=1697
Out of the box this simply works amazingly well with the tag encapsulation you need with HTML, just have a peek at the documentation on that link 
. With Django templates, there is some more syntax which needs to be introduced, and the first two customizations I have added are shortcuts to specify content placeholders and also the master page declaration.
Content Placeholders
The following line is the desired out come:
{% block title %}{% endblock %}
To achieve this I simply type :
title
followed by the key combinations:
yss-
This simply wraps the title word with the required syntax. You will notice I have used the ASCII code from the docs but just changed its function.
Master Page Declaration
The following line is the desired out come:
{% extends “shared/main_master.html” %}
To achieve this I simply type:
“shared/main_master.html”
followed by the key combinations:
yss/
The mappings inside of the surround.vim
The following are the two lines which I am currently using the achieve the above *shortcuts.*
<
let g:surround_45 = "{% block \r %}{% endblock %}"
let g:surround_47 = "{% extends \"\r\" %}"
>
WIN!
