#
# To summarise the summary of the summary:- people are a problem.
# -- The Hitch-Hikers Guide to the Galaxy, Episode 12
#### Desired behaviour of the completions commands.
# the considerations are:
# (1) how many completions are possible
# (2) whether the last command was a completion
# (3) if we can assume that the completer is going to return the same set of
# completions: this is controlled by the ``assume_immutable_completions``
# variable on the reader, which is True by default to match the historical
# behaviour of pyrepl, but e.g. False in the ReadlineAlikeReader to match
# more closely readline's semantics (this is needed e.g. by
# fancycompleter)
#
# if there's no possible completion, beep at the user and point this out.
# this is easy.
#
# if there's only one possible completion, stick it in. if the last thing
# user did was a completion, point out that he isn't getting anywhere, but
# only if the ``assume_immutable_completions`` is True.
#
# now it gets complicated.
#
# for the first press of a completion key:
# if there's a common prefix, stick it in.
# irrespective of whether anything got stuck in, if the word is now
# complete, show the "complete but not unique" message
# if there's no common prefix and if the word is not now complete,
# beep.
# common prefix -> yes no
# word complete \/
# yes "cbnu" "cbnu"
# no - beep
# for the second bang on the completion key
# there will necessarily be no common prefix
# show a menu of the choices.
# for subsequent bangs, rotate the menu around (if there are sufficient
# choices).
