Understanding the 'gh environment' Command (with examples)

The gh environment command is a tool designed to provide users with information about environment variables that can be used with the GitHub CLI (Command Line Interface). The GitHub CLI allows developers to interact with GitHub from the command line, streamlining workflows and enhancing productivity. By understanding the environment variables associated with gh, users can tailor their CLI setup to suit specific needs, automate processes, or integrate seamlessly with other tools.

Use case 1: Display help about environment variables that can be used with gh

Code:

gh environment

Motivation:

The primary motivation for running the gh environment command is to access a comprehensive list of environment variables that can influence the behavior of the GitHub CLI. This is particularly useful for developers who wish to customize their CLI setup or troubleshoot issues related to variable settings. By having a clear understanding of these variables, users can modify their environment for optimal use of the CLI. This command serves as an entry point for users to gain insight into what environmental adjustments are possible, ensuring they can make informed decisions about configuration and automation.

Explanation:

When the command gh environment is executed, it calls upon the GitHub CLI to display help documentation related to environment variables that can be applied to the gh command. The absence of any additional arguments indicates a request for help information rather than the application of a specific environment variable. The command queries the system to collate a list of available environmental parameters, which guide users in customizing their CLI usage. Essentially, it is an information retrieval command that equips users with the knowledge to personalize their CLI environment settings.

Example output:

Upon running the command, you may encounter an output that resembles the following:

Usage: gh [options] <command>

Available environment variables:
  GITHUB_TOKEN: Authentication token for GitHub API requests.
  GH_HOST: The GitHub host to connect to, default is 'github.com'.
  GH_EDITOR: The text editor to use for commands that require text input.
  GH_PAGER: The pager program for output pagination.
