# jprint-wrapper.sh - canonically format JSON to stdout
|
|
#
|
|
# Print JSON in canonical format to standard output.
|
|
#
|
|
# We form a wrapper for the jprint(1), a tool that will format a JSON
|
|
# file into a canonical style.
|
|
#
|
|
# NOTE: As of 2024 Sep 09 the jprint(1) tool has not been written, so jprint-wrapper.sh uses with the jsp tool from:
|
|
#
|
|
# https://github.com/kjozsa/jsp
|
|
#
|
|
# FYI: For macOS, use homebrew to install pipx:
|
|
#
|
|
# brew install pipx
|
|
#
|
|
# Next, use pipx to install jsp:
|
|
#
|
|
# pipx --global install jsp
|
|
#
|
|
# and then be sure that ~/.local/bin is in your $PATH.
|
|
#
|
|
# or the JSONPath.sh(1) tool from:
|
|
#
|
|
# https://github.com/lcn2/JSONPath.sh

# firewall - run only with a bash that is version 5.1.8 or later
|
|
#
|
|
# The "/usr/bin/env bash" command must result in using a bash that
|
|
# is version 5.1.8 or later.
|
|
#
|
|
# We could relax this version and insist on version 4.2 or later. Versions
|
|
# of bash between 4.2 and 5.1.7 might work. However, to be safe, we will require
|
|
# bash version 5.1.8 or later.
|
|
#
|
|
# WHY 5.1.8 and not 4.2? This safely is done because macOS Homebrew bash we
|
|
# often use is "version 5.2.26(1)-release" or later, and the RHEL Linux bash we
|
|
# use often use is "version 5.1.8(1)-release" or later. These versions are what
|
|
# we initially tested. We recommend you either upgrade bash or install a newer
|
|
# version of bash and adjust your $PATH so that "/usr/bin/env bash" finds a bash
|
|
# that is version 5.1.8 or later.
|
|
#
|
|
# NOTE: The macOS shipped, as of 2024 March 15, a version of bash is something like
|
|
# bash "version 3.2.57(1)-release". That macOS shipped version of bash
|
|
# will NOT work. For users of macOS we recommend you install Homebrew,
|
|
# (see https://brew.sh), and then run "brew install bash" which will
|
|
# typically install it into /opt/homebrew/bin/bash, and then arrange your $PATH
|
|
# so that "/usr/bin/env bash" finds "/opt/homebrew/bin" (or whatever the
|
|
# Homebrew bash is).
|
|
#
|
|
# NOTE: And while MacPorts might work, we noticed a number of subtle differences
|
|
# with some of their ported tools to suggest you might be better off
|
|
# with installing Homebrew (see https://brew.sh). No disrespect is intended
|
|
# to the MacPorts team as they do a commendable job. Nevertheless we ran
|
|
# into enough differences with MacPorts environments to suggest you
|
|
# might find a better experience with this tool under Homebrew instead.
