  4#   DESCRIPTION: A varying emoji based theme
  5#        AUTHOR: Alexis Hildebrandt (afh[at]surryhill.net)
  6#       VERSION: 1.0.0
  7#       DEPENDS: emotty plugin
  8#    RECOMMENDS: Hasklig font
  9#
 10# This theme shows a different emoji for each tty at the main prompt.
 11#
 12# There are pre-defined different emoji sets to choose from, e.g.:
 13# emoji, stellar, floral, zodiac, love (see emotty plugin).
 14#
 15# To choose a different emotty set than the default (emoji)
 16# % export emotty_set=nature
 17#
 18# For the superuser (root) this theme shows a designated indicator
 19# and switches the foreground color to red
 20# (see root_prompt variable, default: skull).
 21# But you are using sudo (8) instead of designated a root shell, right‽
 22#
 23# When logged in via SSH the main prompt also shows the user- and hostname.
 24#
 25# The exit status of the last failed command is displayed in the window title
 26# along with an indicator (see warn_glyph variable, default: collision symbol).
 27# To clear it just run: $NULL, true or :
 28#
 29# The right prompt shows the current working directory (3 levels up) in cyan.
 30#
 31# When in a git repository the main prompt shows the current branch name
 32# with a branch indicator in yellow
 33# (see vcs_branch_glyph variable, default: Hasklig branch glyph).
 34#
 35# If there are modified files the prompt switches to red and shows an unstaged
 36# indicator (see vcs_unstaged_glyph variable, default: circled letter M).
 37#
 38# If there are staged files the prompt switches to green and shows an staged
 39# indicator (see vcs_staged_glyph variable, default: high voltage sign).
 40#
 41# In a git repository the right prompt shows the repository name in bold and
 42# prepends the current working directory subpath within the repository.
 43#
 44# When git currently performs an action such as merge or rebase, the action is
 45# displayed in red instead of the branch name and a special action indicator
 46# is shown (see vcs_action_glyph variable, default: chevron).
