Automatically inserting a header in vim

Question

Is there a way to auto add a header when i open a new file in vim? My objective is to automatically add the shebang "#! /usr/bin/python" when i open a new file using the command "vim test.py". If the file is already present, no header should be inserted.

Answer 1

Add this line in your configuration file:

autocmd BufNewFile *.py 0put =\"#!/usr/bin/python\<nl>\"|$

Answer 2

This might be over-kill, but you could look at one of the snippet scripts for Vim, e.g. snipMate -- http://www.vim.org/scripts/script.php?script_id=2540

But, for what you want, you might just map a key to a command that reads in a file. For example:

nmap <leader>r :r boiler_mashbang<cr>

And, then put your boilerplate in the file: boiler_mashbang.
