set -e, -u, -o, -x pipefail

The set lines

These lines deliberately cause your script to fail. Wait, what? Believe me, this is a good thing.
With these settings, certain common errors will cause the script to immediately fail, explicitly and loudly. Otherwise, you can get hidden bugs that are discovered only when they blow up in production.

set -euxo pipefail is short for:

set -e
set -u

GitHub Onboarding and Introduction

A guide for getting started and best practices for teams new to, or improving their interactions with, GitHub

GitHub's features and capabilities

This document is meant to help new teams to GitHub familiarize themselves with the features and platform, as well as start to explore some of the best practices. While not a complete exploration, it's meant as a introduction to the key tenets of using GitHub for your business. For teams and organizations that desire more one on one support, GitHub Professional Services has many different options available to customize tools, training, and process to best meet your needs. The GitHub offerings listed in the diagram above are just a sampling of the various capabilities and we'd love to create a customized offering to meet your specific organizational needs.

Overview and Intr

There are a bunch of reasons why this is convoluted, mostly in building the URL to make the request:

You have to rely on an AJAX request, this example uses jQuery
To make a GetFeatureInfo request, you must provide a BBOX for a image, and the pixel coordinates for the part of the image that you want info from. A couple of squirrely lines of Leaflet code can give you that.
Output formats. The info_format parameter in the request. We don't know a priori which will be supported by a WMS that we might make a request to. See Geoserver's docs for what formats are available from Geoserver. That won't be the same from WMS to WMS, however.
WMS services return XML docs when there's a mistake in the request or in processing. This sends an HTTP 200, which jQuery doesn't think is an error.
