# Prompt Segment Constructors
#
# Methodology behind user-defined variables overwriting colors:
# The first parameter to the segment constructors is the calling function's
# name. From this function name, we strip the "prompt_"-prefix and
# uppercase it. This is then prefixed with "POWERLEVEL9K_" and suffixed
# with either "_BACKGROUND" or "_FOREGROUND", thus giving us the variable
# name. So each new segment is user-overwritable by a variable following
# this naming convention.
################################################################

# when building the left-hand prompt. Because the RPROMPT is created from
# right-left but reads the opposite, this isn't necessary for the other side.
CURRENT_BG='NONE'
# Begin a left prompt segment
# Takes four arguments:
# * $1: Name of the function that was orginally invoked (mandatory).
# Necessary, to make the dynamic color-overwrite mechanism work.
# * $2: A flag if the segment should be joined with the previous one.
# * $3: Background color
# * $4: Foreground color
# * $5: The segment content
# * $6: An identifying icon (must be a key of the icons array)
# The latter three can be omitted,
