#   DESCRIPTION: A varying emoji based theme
#        AUTHOR: Alexis Hildebrandt (afh[at]surryhill.net)
#       VERSION: 1.0.0
#       DEPENDS: emotty plugin
#    RECOMMENDS: Hasklig font
#
# This theme shows a different emoji for each tty at the main prompt.
#
# There are pre-defined different emoji sets to choose from, e.g.:
# emoji, stellar, floral, zodiac, love (see emotty plugin).
# 
# To choose a different emotty set than the default (emoji)
# % export emotty_set=nature
#
# For the superuser (root) this theme shows a designated indicator
# and switches the foreground color to red
# (see root_prompt variable, default: skull).
# But you are using sudo (8) instead of designated a root shell, right‽
#
# When logged in via SSH the main prompt also shows the user- and hostname.
#
# The exit status of the last failed command is displayed in the window title
# along with an indicator (see warn_glyph variable, default: collision symbol).
# To clear it just run: $NULL, true or :
#
# The right prompt shows the current working directory (3 levels up) in cyan.
#
# When in a git repository the main prompt shows the current branch name
# with a branch indicator in yellow
# (see vcs_branch_glyph variable, default: Hasklig branch glyph).
#
# If there are modified files the prompt switches to red and shows an unstaged
# indicator (see vcs_unstaged_glyph variable, default: circled letter M).
#
# If there are staged files the prompt switches to green and shows an staged
# indicator (see vcs_staged_glyph variable, default: high voltage sign).
#
# In a git repository the right prompt shows the repository name in bold and
# prepends the current working directory subpath within the repository.
#
# When git currently performs an action such as merge or rebase, the action is
# displayed in red instead of the branch name and a special action indicator
# is shown (see vcs_action_glyph variable, default: chevron).
