## bobthefish
bobthefish is a Powerline-style, Git-aware fish theme optimized for awesome.
![bobthefish][screenshot]
You will probably need a [Powerline-patched font][patching] for this to work.
[I recommend picking one of these][fonts].
This theme is based loosely on [agnoster][agnoster].
### Features
* A helpful, but not too distracting, greeting.
* A subtle timestamp hanging out off to the right.
* Powerline-style visual hotness.
* More colors than you know what to do with.
* An abbreviated path which doesn't abbreviate the name of the current project.
* All the things you need to know about Git in a glance.
* Visual indication that you can't write to the current directory.
### The Prompt
* Flags:
* Previous command failed (!)
* Background jobs (%)
* You currently have superpowers ($)
* User@Host (unless you're the default user)
* Current RVM or rbenv (Ruby) version
* Current virtualenv (Python) version
* Abbreviated parent directory
* Current directory, or Git or Mercurial project name
* Current project's repo branch ( master) or detached head (➦ d0dfd9b)
* Git or Mercurial status, via colors and flags:
* Dirty working directory (*)
* Untracked files (…)
* Staged changes (~)
* Stashed changes ($)
* Unpulled commits (-)
* Unpushed commits (+)
* Unpulled *and* unpushed commits (±)
* _Note that not all of these have been implemented for hg yet :)_
* Abbreviated project-relative path
### Configuration
You can override some default options in your `config.fish`:
set -g theme_display_git no
set -g theme_display_hg yes
set -g theme_display_virtualenv no
set -g theme_display_ruby no
set -g theme_display_user yes
set -g default_user your_normal_user
