# trapd00r.zsh-theme
#
# This theme needs a terminal supporting 256 colors as well as unicode.
# In order to avoid external dependencies, it also has a zsh version of
# the previously used perl script https://github.com/trapd00r/utils/blob/master/zsh_path,
# which splits up the current path and makes it fancy.
#
# By default it spans over two lines like so:
#
# scp1@shiva:pts/9-> /home » scp1 (0)
# >
#
# that's  user@host:pts/-> splitted path (return status)
#
# If the current directory is a git repository, we span 3 lines;
#
# git❨ master ❩ DIRTY
# scp1@shiva:pts/4-> /home » scp1 » dev » utils (0)
# >
