Small shell (bash/zsh) prompt generator written in C. Can use powerline symbols.

Features

single executable, no external processes
configurable with a header file (like dwm)
powerline-style
git branch name and status

Installation

Arch Linux PKGBUILD included. Generate the .tar.xz and install (needs root privileges) with:

makepkg -i

Manual install:

git clone git://github.com/tryone144/arrowline.git
cd ./arrowline
make

Systemwide installation (as root) into /usr/local/bin:

make install

If you install by hand make sure that git is installed for git status support.

Configuration

All configuration takes place in config.h.

Define the colors for the segments.
Define the use of powerline symbols and escape chararcters
Select which segments to show (NULL-terminated array of generators)

Segment List

STATUS: display red X if last command's exit status != 0
HOST: display username and hostname
CWDPREFIX: display the working directory prefix home root or deep inside
CWD: display CWD_LEN (defaults to 3) folders of current working directory
VCS`: display branch and status if current working dir is inside a version controlled directory
- currently only supports git

Using arrowline

bash

Put into your .bashrc:

# arrowline prompt
function _update_ps1() {
    export PS1="$( arrowline ${?} 2> /dev/null || echo 'arrowline failed! [\u@\h \W]\$ ' )"
}
export PROMPT_COMMAND=_update_ps1

KNOW ISSUES

libgit2 updates seem to break the binary. A simple rebuild should be enough. See this Issue.
