# 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-overwritten by a variable following
#     this naming convention.
################################################################

# The `CURRENT_BG` variable is used to remember what the last BG color used was
# 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 originally invoked (mandatory).
#         Necessary, to make the dynamic color-overwrite mechanism work.
#   * $2: The array index of the current segment
#   * $3: Background color
#   * $4: Foreground color
#   * $5: The segment content
#   * $6: An identifying icon (must be a key of the icons array)
