📄 Why You Should Always End Files With a Newline

One of the most common (and often misunderstood) code review comments is:

“Please add a newline at the end of the file.”

In GitHub, you’ll see a little "⛔ no entry" icon at the end of a file when this is missing. This Gist explains why it matters, when it's necessary, and how to fix or automate it in your editor or workflow.

# Why? In a containerised environment, you may need to run commands on other Docker containers
# within the Docker bridge network. For slim images such as Alpine-based distributions, you do
# not want the docker executable installed. Instead, you can simply pass the docker socket during
# runtime, and interact with it using cURL. The following functions allow you to easily interact
# with other containers, as you would using the native docker exec command.

# Example of mounting the docker socket:

For a simplistic view on what versioning ranges look like, see below:

Version                   Range
>=1.0                     1.0.0 - *.*.*
>=1.0 <2.0                1.0.0 - 1.*.*
>=1.0 <1.1 || >=1.2       1.0.0 - 1.*.* || 1.2.0 - *.*.*
>=1.0 <1.1                1.0.0 - 1.*.*
>=1.0.0 <2.1              1.0.* - 2.0.*
>=1.0.0 <=2.1.0           1.0.0 - 2.1.0
~1.2                      1.2.0 - 1.*.*
