# Run nbconvert acceptance tests
# ------------------------------
#
# This script must be called from the root directory of IHaskell. It requires
# `jq` to be available in the $PATH.
#
# Positional arguments to this script are the invocation for `nbconvert`.
# For example:
#
# Invoke from the the root IHaskell directory:
#
#    test/acceptance.nbconvert.sh jupyter nbconvert
#
# Invoke with `stack` from the the root IHaskell directory:
#
#    test/acceptance.nbconvert.sh stack exec -- jupyter nbconvert
#
# Invoke with Stack+Docker from the the root IHaskell directory:
#
#    test/acceptance.nbconvert.sh stack --docker exec -- jupyter nbconvert
#
# Invoke with Nix from the root IHaskell directory:
#
#    test/acceptance.nbconvert.sh result/bin/jupyter-nbconvert
