#
# commandline asciii kanban board for minimalist productivity bash hackers (csv-based)
#
# Usage:
#
# kanban init # initialize kanban in current directory
# kanban add # add item interactive (adviced)
# kanban show [status] .... # show ascii kanban board [with status]
# kanban <id> # edit or update item
# kanban <id> <status> # update status of todo id (uses $EDITOR as preferred editor)
# kanban <status> ..... # list only todo items with this status(es)
# kanban list # list all todos (heavy)
# kanban tags # list all submitted tags
# kanban add <status> <tag> <description> # add item (use quoted strings for args)
# kanban stats status [tag]
# kanban stats tag
# kanban stats history
# kanban csv # edit raw csv
#
# NOTE #1: statuses can be managed in ~/.kanban/.kanban.conf
# NOTE #2: the database csv can be found in ~/.kanban/.kanban.csv
#
# Examples:
#
# kanban add TODO projectX "do foo"
# kanban TODO DOING HOLD
# kanban stats status projectX
# kanban stats tag projectX
# # notekeeping by entering a filename as description:
# echo hello > note.txt && kanban add DOING note.txt
# # store in github repo
# git clone https://../foo.git && cd foo.git && kanban init && git add .kanban
#
# Environment:
#
# X=120 kanban .... # set max line-width to 120
# NOCOLOR=1 kanban .... # disable colors
# PLAIN=1 kanban ... # plaintext, disable utf8 chars
#
# Tips:
#
# * <current_dir>/.kanban or ~/.kanban dir is checked for configuration / data
# * put .kanban directories in project-dirs
# * entering an existing text-filename as description enables note-keeping
