Overview
========

Ever since I discovered CDPATH last year I've been thinking wouldn't it
be great if Vim could access files using CDPATH without having to chdir
anywhere first. In other words, why can't Vim understand that it has to
look for tklbam/restore.py in the CDPATH instead of telling me that it
doesn't exist in the current working directory?

I started experimenting with Vim hooks and eventually figured out how to
implement this as a generic mechanism that defines a more useful way for
Vim to access the filesystem.

Throw in a Python implemented autocomplete algorithm, and in a nutshell, thats
how smart open works.

Configuration
=============

In your bashrc file:;

    export _CDPATH=$CDPATH

Path lookup algorithm
=====================

1. Try to lookup path in cdpath
2. If no such file exists, try looking up path as a tag
3. If no such tag exists, assume its a new file

   Lookup the path of this new file by trying to find its parent directory in
   the cdpath. If it doesn't have a parent directory, assume the new file
   should be created in the current working directory.

Special cases::

    /path   path is absolute (not looked up)
    ./path  path is relative to the current working directory (not looked up)

Usage
=====

commands::

    :O[pen]         [ <path> ]
    :Ta[bOpen]      [ <path> ]
    :Sp[litOpen]    [ <path> ]

    if no <path> argument provided:
        defaults to taking <path> from word under cursor

Note: shell-style autocomplete is supported, but only for filesystem paths,
not tags.

key bindings::

    gf      open file or tag (under cursor)
    CTRL-]  open file or tag (under cursor)

    <C-W>f  open file (under cursor) in split window
    <C-T>   go back

Note: overloaded vim native keybindings, with new enhanced functionality.

mouse bindings (browser-inspired)::

    left double click to open link

        doubleclick         open
        shift-doubleclick   split open
        ctrl-doubleclick    tab open (like in a browser)

    ctrl-rightclick         go back
