Detailed Description

Entry point for the application. Parses command-line arguments and either starts the HTTP server or fetches and displays a GitHub user.

This file contains the main function which acts as the orchestrator of the program. It interprets the configuration from the user, and based on that configuration, it either launches a local HTTP server or performs a GitHub API request to fetch user data, then displays it to stdout.

Function Documentation

main()

int main	(	int	argc,
		char **	argv )

Main function that initializes and runs the application.

This function performs the following steps:

• Parses command-line arguments into an AppConfig object.
• Based on the parsed configuration:
  • If run_server is true, launches the HTTP server on the specified port.
  • Otherwise, fetches a GitHub user and prints the result.

Any exceptions thrown during the execution are caught and logged to stderr, with a non-zero return code indicating failure.

Parameters

argc	Argument count.
argv	Argument vector.

Returns

int Exit status code (0 for success, non-zero for failure).
