require_relative 'tokenize_option'
module Cmds
# escape option hash.
#
# this is only useful for the two common option styles:
#
# - single character keys become `-<char> <value>`
#
# {x: 1} => "-x 1"
#
# - longer keys become `--<key>=<value>` options
#
# {blah: 2} => "--blah=2"
#
# if you have something else, you're going to have to just put it in
# the cmd itself, like:
#
# Cmds "blah -assholeOptionOn:%{s}", "ok"
#
# or whatever similar shit said command requires.
#
# however, if the value is an Array, it will repeat the option for each
# value:
#
# {x: [1, 2, 3]} => "-x 1 -x 2 -x 3"
# {blah: [1, 2, 3]} => "--blah=1 --blah=2 --blah=3"
#
# i can't think of any right now, but i swear i've seen commands that take
# opts that way.
