Here's a solution I hammered out:
function gettmp
set DIRNAME tmp-dir.(uuidgen)
mkdir $DIRNAME
cd $DIRNAME
end
set -gx SET_PWD "$PWD"
set -gx OLD_PWD "$PWD"
function react_to_pwd --on-variable PWD
set -gx OLD_PWD "$SET_PWD"
set -gx SET_PWD "$PWD"
switch "$OLD_PWD"
case "*tmp-dir.*"
switch "$PWD"
case "*tmp-dir.*"
echo -n ""
case "*"
echo "Removing $OLD_PWD"
rm -rf "$OLD_PWD"
end
end
end
The react_to_pwd is called any time PWD changes and keeps track of the
last PWD that was set. Then, anytime you change out of a directory
containing tmp-dir.* into a non-temp directory, the old directory will
be removed.
gettmp just creates and cd's into a directory with that naming scheme.

I occasionally need to do various tasks that require the creation of a
temporary directory, something like:
$ mkdir tmp
$ cd tmp
$ unzip ../foo.zip
$ # do something to the contents of tmp
$ cd ..
$ rm -rf tmp
What's the idiomatic fish way of creating the directory (with a
random, unique name) and ensuring it's deleted? Do I need to dirty my
hands with /usr/bin/mktemp??
