GitHub Latest Release Checker

This Go script checks if the latest release of a given GitHub repository is within a specified number of days from today. It fetches the latest release information from the GitHub API and compares the release date with the current date.

Usage

go run main.go <repository_name> <days>

Example

go run main.go 'owner/repo' 30

Command Line Arguments

• <repository_name>: The GitHub repository in the format owner/repo.
• <days>: The number of days to check if the latest release is within.

Output

• The script prints the tag name of the latest release if it was published within the specified number of days.
• If the release is older than the specified number of days, it prints none.

Error Handling

The script will panic and display error messages in the following scenarios:

• Insufficient command line arguments.
• Invalid repository name format (must be owner/repo).
• Non-integer value for the days argument.
• Errors in fetching or parsing the latest release information from the GitHub API.
• Unexpected status codes from the GitHub API response.

Detailed Steps

1. Argument Parsing and Validation:
   • The script checks that at least 3 command line arguments are provided.
   • Validates the format of the repository name.
   • Ensures the days argument is an integer.
2. Fetch Latest Release:
   • Constructs the API URL for the latest release of the specified repository.
   • Makes an HTTP GET request to the GitHub API.
   • Parses the JSON response to extract the latest release information.
3. Check Release Date:
   • Compares the release date with the current date to determine if it is within the specified number of days.
4. Output Result:
   • Prints the tag name of the latest release if it is recent.
   • Prints none if the release is older than the specified number of days.

Notes

• Ensure the repository name is in the format owner/repo.
• The GitHub API has rate limits; be mindful of making too many requests in a short period.
