+# A Powerline style prompt for your shell
+
+A [Powerline](https://github.com/Lokaltog/vim-powerline) like prompt for Bash,
+ZSH and Fish. Based on [Powerline-Shell](https://github.com/banga/powerline-shell) by @banga.
+Ported to golang by @justjanne.
+
+![MacVim+Solarized+Powerline+CtrlP](https://raw.github.com/banga/powerline-shell/master/bash-powerline-screenshot.png)
+
+- Shows some important details about the git/hg branch (see below)
+- Changes color if the last command exited with a failure code
+- If you're too deep into a directory tree, shortens the displayed path with an ellipsis
+- Shows the current Python [virtualenv](http://www.virtualenv.org/) environment
+- It's easy to customize and extend. See below for details.

+  - [ZSH](#zsh)
+  - [Fish](#fish)
+
+## Version Control
+
+All of the version control systems supported by powerline shell give you a
+quick look into the state of your repo:
+
+- The current branch is displayed and changes background color when the
+  branch is dirty.
+- When the local branch differs from the remote, the difference in number
+  of commits is shown along with `⇡` or `⇣` indicating whether a git push
+  or pull is pending
+
+In addition, git has a few extra symbols:
+
+- `✎` -- a file has been modified, but not staged for commit
+- `✔` -- a file is staged for commit
+- `✼` -- a file has conflicts
+- `+` -- untracked files are present
+
+Each of these will have a number next to it if more than one file matches.
+
+## Setup
+
+This script uses ANSI color codes to display colors in a terminal. These are
+notoriously non-portable, so may not work for you out of the box, but try
+setting your $TERM to `xterm-256color`, because that works for me.
+
+- Patch the font you use for your terminal: see
+  [powerline-fonts](https://github.com/Lokaltog/powerline-fonts)
+  - If you struggle too much to get working fonts in your terminal, you can use
+    "compatible" mode.
+  - If you're using old patched fonts, you have to use the older symbols.
+    Basically reverse [this
+    commit](https://github.com/milkbikis/powerline-shell/commit/2a84ecc) in
+    your copy
+
+- Set your GOPATH (otherwise the package will be installed in $HOME/go/bin/)
+
+- Download and install the package
+
+```
+go get github.com/justjanne/powerline-go
+```
+
+- Move it to a convenient place (for example, `~/.powerline/powerline-go`)
+
+### All Shells
+
+There are a few optional arguments which can be seen by running
+`powerline-go -help`.
+
+```
+Usage of powerline-go:
+  -colorize-hostname
+        Colorize the hostname based on a hash of itself
+  -cwd-max-depth int
+        Maximum number of directories to show in path
+        (default 5)
+  -cwd-max-dir-size int
+        Maximum number of letters displayed for each directory in the path
+        (default -1)
+  -cwd-mode string
+        How to display the current directory
+        (default "fancy")
+  -error int
+        Exit code of previously executed command
+  -mode string
+        The characters used to make separators between segments.
+        (valid choices: patched, compatible, flat)
+        (default "patched")
+  -modules string
+        The list of modules to load. Separate with ','
+        (valid choices: cwd, exit, git, hg, host, jobs, perms, root, ssh, user, venv)
+        (default "venv,user,ssh,host,cwd,perms,jobs,exit,root")
+  -shell string
+        Set this to your shell type
+        (valid choices: bare, bash, zsh)
+        (default "bash")
+```
+
+### Bash
+
+Add the following to your `.bashrc` (or `.profile` on Mac):
+
+```
+function _update_ps1() {
+    PS1="$(~/.powerline/powerline-go -error $?)"
+}
+
+if [ "$TERM" != "linux" ]; then
+    PROMPT_COMMAND="_update_ps1; $PROMPT_COMMAND"
+fi
+```
+
+### ZSH
+
+Add the following to your `.zshrc`:
+
+```
+function powerline_precmd() {
+    PS1="$(~/.powerline/powerline-go -error $? -shell zsh)"
+}
+
+function install_powerline_precmd() {
+  for s in "${precmd_functions[@]}"; do
+    if [ "$s" = "powerline_precmd" ]; then
+      return
+    fi
+  done
+  precmd_functions+=(powerline_precmd)
+}
+
+if [ "$TERM" != "linux" ]; then
+    install_powerline_precmd
+fi
+```
+
+### Fish
+
+Redefine `fish_prompt` in `~/.config/fish/config.fish:`
+
+```
+function fish_prompt
+    ~/.powerline/powerline-go -error $status -shell bare
+end
+```
+
+## Customization
+
+### Adding, Removing and Re-arranging segments
+
+You can use the `-modules` argument to define which segments to draw, and in
+which order. Segments can also be repeated. Simply change the argument in your
+shell’s init to customize the prompt.
