# Michele Bologna's theme
# https://www.michelebologna.net
#
# This a theme for oh-my-zsh. Features a colored prompt with:
# * username@host: [jobs] [git] workdir %
# * hostname color is based on hostname characters. When using as root, the
# prompt shows only the hostname in red color.
# * [jobs], if applicable, counts the number of suspended jobs tty
# * [git], if applicable, represents the status of your git repo (more on that
# later)
# * '%' prompt will be green if last command return value is 0, yellow otherwise.
#
# git prompt is inspired by official git contrib prompt:
# https://github.com/git/git/tree/master/contrib/completion/git-prompt.sh
# and it adds:
# * the current branch
# * '%' if there are untracked files
# * '$' if there are stashed changes
# * '*' if there are modified files
# * '+' if there are added files
# * '<' if local repo is behind remote repo
# * '>' if local repo is ahead remote repo
# * '=' if local repo is equal to remote repo (in sync)
# * '<>' if local repo is diverged
