Detailed Description

Contains logic for parsing command-line arguments into an AppConfig object.

This file provides the implementation of a utility function that translates raw command-line input into structured configuration for the application.

Definition in file config.cpp.

Function Documentation

parse_arguments()

AppConfig parse_arguments

(

const std::vector< std::string > &

args

)

Parses command-line arguments into an AppConfig structure.

This function iterates over the provided command-line arguments and looks for:

• --user <username> or --user=<username>: Sets the GitHub username to fetch.
• --server: Indicates that the HTTP server should be started.
• --port=<number>: Sets the port number for the HTTP server.

Invalid port values will cause an exception to be thrown.

Parameters

args	A list of command-line arguments, excluding the program name.

Returns

AppConfig A structure populated with the extracted configuration.

Exceptions

std::invalid_argument

If the port value is not a valid integer.
