# Stash/unstash support for per-directory variables
#
# Adopted for zsh-autoenv.
#
# Copyright (c) 2009,2012 Dave Olszewski <cxreg@pobox.com>
# http://github.com/cxreg/smartcd
#
# This code is released under GPL v2 and the Artistic License, and
# may be redistributed under the terms of either.
#
#
# This library allows you to save the current value of a given environment
# variable in a temporary location, so that you can modify it, and then
# later restore its original value.
#
# Note that you will need to be in the same directory you were in when you
# stashed in order to successfully unstash. This is because the temporary
# variable is derived from your current working directory's path.
#
# Usage:
# stash PATH
# export PATH=/something/else
# [...]
# unstash PATH
#
# Note that this was written for use with, and works very well with,
# smartcd. See the documentation there for examples.
#
# An alternate usage is `autostash' which will trigger autounstash when
# leaving the directory, if combined with smartcd. This reduces the amount
# of explicit configuration you need to provide:
#
# autostash PATH
# export PATH=/something/else
#
# You may also do both operations on line line, leaving only the very succinct
#
# autostash PATH=/something/else
#
# If you attempt to stash the same value twice, a warning will be displayed
# and the second stash will not occur. To make it happen anyway, pass -f
# as the first argument to stash.
#
# $ stash FOO
# $ stash FOO
# You have already stashed FOO, please specify "-f" if you want to overwrite another stashed value
# $ stash -f FOO
# $
#
# This rule is a bit different if you are assigning a value and the variable
# has already been stashed. In that case, the new value will be assigned, but
# the stash will not be overwritten. This allows for non-conflicting chained
# stash-assign rules.
