#
# A minimal two-color theme.
#
# Authors:
#   Kevin Laude <nerfyoda@gmail.com>
#
# Features:
#   - One line, left aligned.
#   - The prompt is prefixed by a character sequence of your choice.
#   - Only displays the current directory instead of the full path.
#   - Displays the current branch when in a git project (this requires loading
#     the git module before prompt in ~/.zpreztorc).
#   - Displays a character at the end of the prompt when in a git project with
#     "dirty" files.
#
# Usage:
#   This prompt's prefix symbol and colors are customizable:
#     prompt cloud [<symbol>] [<color1>] [<color2>]
#
#   In ~/.zpreztorc:
#     zstyle ':prezto:module:prompt' theme 'cloud' \
#       ['<symbol>'] \
#       ['<color1>'] \
#       ['<color2>']
#
#   If these options are not provided, the symbol defaults to "☁" with colors
#   cyan and green.

#
# Note:
#   This is a port of the oh-my-zsh cloud theme, originally written by Phillip
#   Ridlen <p@rdln.net> and Mark Drago <markdrago@gmail.com>
