github_pr_inspector.info

Let’s break down what this script does in detail. The script is named github_pr_inspector.sh, authored by GJS (homelab-alpha), and its purpose is to manage GitHub pull request inspection by allowing users to generate .patch and .diff links and view PR changes directly in the terminal.

Here’s a detailed explanation:

Script Metadata link

• Author: GJS (homelab-alpha)
• Date: Jan 03, 2025
• Version: 1.0.0
• Description: This script provides an interactive interface for generating .patch and .diff links for GitHub pull requests. It allows users to inspect PR changes directly in their terminal by accessing these links. The script supports interactive menu options, hardcoded repositories, and custom input, ensuring a flexible user experience
• RAW Script: github_pr_inspector.sh

Script Header link

The script starts with metadata comments, including the script’s author, version, and a brief description. The header also includes usage instructions, with details about required dependencies such as curl and less.

Requirements link

The script checks for the following dependencies, which must be installed on the user’s system for it to work correctly:

• curl (to fetch GitHub PR data)
• less (to view the PR data in the terminal)

Usage link

Command-Line Usage link

The script can be executed directly with the following command structure:

./github_pr_inspector.sh [username/repository] [pr_number]

• If no parameters are passed, the script will show an interactive menu.
• Optional flags:
  • -h or --help: Display the help menu.
  • -r or --reset: Reset the session and start fresh.
  • -q or --quit: Exit the script.

Examples link

1. Generate links for PR #123 in a specific repository:

./github_pr_inspector.sh username/repository 123

2. Use the interactive menu:

./github_pr_inspector.sh

Aliases link

To create convenient aliases for the script, add the following lines to your shell configuration file (e.g., .bashrc or .bash_aliases):

alias github-pr-inspector="$HOME/github_pr_inspector.sh"
# or
alias github-pr-inspector="$HOME/.bash_aliases/github_pr_inspector.sh"

Main Menu link

Upon execution, the script presents an interactive menu for the user to select one of the following options:

1. Github: homelab-alpha
2. Github: louislam/uptime-kuma
3. Custom: username/repository

Additionally, users can interact with the following options:

• h or --help: Show the help menu.
• r or --reset: Reset the session and start over.
• t or --toggle: Toggle between .patch and .diff as the default file extension.
• q or --quit: Exit the script.

Handling User Input link

• The script will ask for a GitHub repository and a pull request number if they are not already provided.
• Repository format: The repository input must follow the username/repository format (e.g., homelab-alpha/shell-script).
• PR Number: The user will also need to input the pull request number.

Once the repository and PR number are validated, the script generates the appropriate .patch or .diff link, depending on the chosen file extension (toggled by the user).

Fetching PR Files link

The script generates two types of links for PR inspection:

1. .patch: Displays the changes in a patch format.
2. .diff: Displays the changes in a diff format.

Upon selecting a repository and PR number, the script fetches the corresponding file using curl and displays it using less.

If the file cannot be retrieved (i.e., a non-200 HTTP status is returned), the script will notify the user of the failure.

Reset Functionality link

The --reset option resets all previously entered data (repository, PR number, etc.), allowing the user to start from a clean slate.

Toggle Between .patch and .diff link

The script defaults to .patch files, but users can toggle between .patch and .diff formats by pressing the t or --toggle option.

Handling Command-Line Arguments link

• If the script is run with two arguments (repository and PR number), it will skip the interactive menu and fetch both .patch and .diff links for the specified PR.
• Example usage:

./github_pr_inspector.sh username/repository 123

This will generate both .patch and .diff links for PR #123 in the username/repository repository.

Conclusion link

The github_pr_inspector.sh script offers a user-friendly way to view GitHub PR changes directly in the terminal. Its interactive menu, support for custom repositories, and file extension toggling ensure a flexible and efficient experience for GitHub users.
