My custom (and favorite) zsh shell theme.

razor.zsh-theme

# Great Scott! Aliens, arrows and paths!

ZSH_THEME_GIT_PROMPT_PREFIX="%{$fg_bold[blue]%}|%{$reset_color%}%{$reset_color%}%{$fg_bold[magenta]%}"
ZSH_THEME_GIT_PROMPT_SUFFIX="%{$reset_color%} "
ZSH_THEME_GIT_PROMPT_DIRTY="%{$reset_color%}%{$fg_bold[blue]%}|%{$reset_color%}👽"
ZSH_THEME_GIT_PROMPT_CLEAN="%{$reset_color%}%{$fg_bold[blue]%}|"

# Create a function to get the prompt path and show absolute path when in $HOME dir
prompt_path() {
    local dir="$PWD"

    if [[ "$dir" == "$HOME" ]]; then
        # If in the home directory, print the full path to the home directory
        echo "${HOME%/*}"
        return
    fi

    # If the path is within the home directory, but not the home directory itself, replace $HOME with ~
    dir="${dir/$HOME\//~/}"

    # Return the full path minus the current directory
    echo "${dir%/*}"
}

PROMPT='%{$fg[cyan]%}$(prompt_path)/%{$fg_bold[cyan]%}$(basename $PWD)%{$reset_color%} $(git_prompt_info)'
# Show a red arrow if the last command failed, green if succeeded
PROMPT+="%(?:%{$fg_bold[green]%}➜ :%{$fg_bold[red]%}➜ )%{$reset_color%}"

Just for the record the way recommended way to set up this theme is to:

1. Put it into your ~/.oh-my-zsh/themes directory.
2. Set your ZSH_THEME in ~/.zshrc to the theme filename, i.e.razor.
