#!/usr/bin/env ruby

# Remote control for Trello
#
# To configure, get a Trello developer key, and stick it in `~/.trello-remote`
#
#    # ~/.trello-remote
#    TRELLO_DEVELOPER_PUBLIC_KEY=<your key>
#
# Next run `trello-remote token`, follow the instructions in your
# browser, you'll get a token back. Add it to `~/.trello-remote`
#
#    # ~/.trello-remote
#    TRELLO_DEVELOPER_PUBLIC_KEY=<your key>
#    TRELLO_MEMBER_TOKEN=<your token>
#
# Now you can start using your remote! Try this
#
#    trello-remote console
#
# You'll get a Pry console, for example to archive all cards in the
# "Development" board in the "Done" list, you can do
#
#    find_list(/dev/i, /done/i).cards.each(&:close!)
#
# find_board and find_list can both take an exact string, or a regexp
# to match.
#
# * trello-remote show board_name#id
#     display a ticket, board_name can be partial and is case
#     insentive. id is the number you find in the ticket's url
#
# * trello-remote comment board_name#id -m "message"
#     add a comment to a card
#
# * trello-remote list board_name:list_name
#     list all cards in a list
