Using the jsonnet docker image

jsonnet

#! /usr/bin/env bash

# The script wraps around the jsonnet docker image to so it can be run without installing 
# python locally. This script is also geared towards a windows setup as it currently is
# environment I'm working in. With the exception of the TTY wrappers I think this should
# generally work for any *nix system as well.
#
# Clearly access to a docker host is required to make this work... For a windows setup
# we will also be assuming that all the relevant drives (C, D, whatever) are mounted on
# the docker host under "/c", "/d", etc. 
#

#
# Check if we actually have the jsonnet image, otherwise fetch it. We'll be using the
# mexisme image by default which can be found here: https://hub.docker.com/r/mexisme/jsonnet.
# It comes with some suggested aliases which were the basis of this script.
#

docker pull --quiet mexisme/jsonnet:latest > /dev/null

docker run                                              \
    --volume "//c://c"                                  \
    --entrypoint "//jsonnet"                            \
    --workdir "/$( cygpath --unix --absolute $PWD )"    \
    mexisme/jsonnet:latest "$@"
