import os

def head(filename, count=1):
    """
    This one is fairly trivial to implement but it is here for completeness.
    """
    with open(filename, 'r') as f:
        lines = [f.readline() for line in xrange(1, count+1)]
        return filter(len, lines)

How to use Tim Pope’s Pathogen

I’ll assume you are on Linux or Mac OSX. For Windows, replace ~/.vim/ with $HOME\vimfiles\ and forward slashes with backward slashes.

The idea

Vim plugins can be single scripts or collections of specialized scripts that you are supposed to put in “standard” locations under your ~/.vim/ directory. Syntax scripts go into ~/.vim/syntax/, plugin scripts go into ~/.vim/plugin, documentation goes into ~/.vim/doc/ and so on. That design can lead to a messy config where it quickly becomes hard to manage your plugins.

This is not the place to explain the technicalities behind Pathogen but the basic concept is quite straightforward: each plugin lives in its own directory under ~/.vim/bundle/, where each directory simulates the standard structure of your ~/.vim/ directory.

    # Your query's body
