A functional, uncluttered theme. Boasts the following features:

Left Prompt:
* Current virtualenv (if applicable)
* Truncated CWD (just the current folder's name)
* Git branch and dirty state (if applicable)

Right Prompt:
* Full CWD path
* Last error code (if applicable)

.rvmrc is depreciated

add gitignore.io cli function for fish 

Minimal prompt theme.

Displays the $CWD only. If you are connected through ssh the hostname
will also be shown.

I like my prompt uncluttered. If I need to know if my git repo is
dirty I run `git st`. If I get lost and need to know which branch
I'm on it takes my fingers 2 seconds to type `git br<C-f>`.

The right prompt displays the last commands exit code if it was
non-zero. It requires a recent version of fish from git.

Yet another custom theme

readme matching config, no git plugin
