Oh my Zsh getting the username@hostname and full path in the default theme

blatantly copied from this git issue response

cp $ZSH/themes/robbyrussel.zsh-theme $ZSH_CUSTOM/themes/ open $ZSH_CUSTOM/themes/robbyrussel.zsh-theme in text editor and change to:

local ret_status="%(?:%{$fg_bold[green]%}➜ :%{$fg_bold[red]%}➜ )"
PROMPT='${ret_status} %{$fg_bold[magenta]%}%n%{$reset_color%}%{$FG[146]%}@%{$reset_color%}%{$fg_bold[blue]%}%m%{$reset_color%}  %{$fg_bold[cyan]%}%~%{$reset_color%} $(git_prompt_info)'

ZSH_THEME_GIT_PROMPT_PREFIX="%{$fg_bold[blue]%}git:(%{$fg[red]%}"
ZSH_THEME_GIT_PROMPT_SUFFIX="%{$reset_color%} "
ZSH_THEME_GIT_PROMPT_DIRTY="%{$fg[blue]%}) %{$fg[yellow]%}✗"
ZSH_THEME_GIT_PROMPT_CLEAN="%{$fg[blue]%})"

logout and login and enjoy
