URI Library

This is a robust C library for parsing and managing Uniform Resource Identifiers (URIs). It supports the extraction of various components of a URI, such as the scheme, user info, host, port, path, query, and fragment.

Features

• Parse and create a URI structure from a string.
• Extract different components of the URI.
• Retrieve the full URI as a string.
• Memory management for URI structures.

Getting Started

Prerequisites

• A C compiler (e.g., GCC)
• CMake (version 3.18 or higher)

Installation

1. Clone the repository:

   git clone https://github.com/Awl-S/uri.git
   cd uri

2. Compile the library and example program:

   gcc -o main main.c uri.c

3. Compile the library and example program using CMake:

   mkdir build
   cd build
   cmake ..
   make

Usage

Include the header file in your C program:

#include "uri.h"

Create and use a URI:

#include "uri.h"
#include <stdio.h>

int main() {
    struct Uri *my_uri = uriCreate("http://user:[email protected]:8080/path?query#fragment");
    if (!my_uri) {
        fprintf(stderr, "Failed to create URI\n");
        return 1;
    }

    printf("Scheme: %s\n", uriGetScheme(my_uri));
    printf("User Info: %s\n", uriGetUserInfo(my_uri));
    printf("Host: %s\n", uriGetHost(my_uri));
    printf("Port: %s\n", uriGetPort(my_uri));
    printf("Path: %s\n", uriGetPath(my_uri));
    printf("Query: %s\n", uriGetQuery(my_uri));
    printf("Fragment: %s\n", uriGetFragment(my_uri));

    char *full_uri = uriGetFullUri(my_uri);
    if (full_uri) {
        printf("Full URI: %s\n", full_uri);
        free(full_uri);
    }

    uriDestroy(my_uri);
    return 0;
}

API Reference

uriCreate

struct Uri *uriCreate(const char *uriString);

Creates and parses a URI structure from the given string.

• uriString: URI string.
• Returns a pointer to the created Uri structure, or nullptr if it fails.

uriDestroy

void uriDestroy(struct Uri *uri); 

Destroys the URI structure and frees allocated memory.

• uri: Pointer to the Uri structure to destroy.

uriGetScheme

char *uriGetScheme(const struct Uri *uri);

Retrieves the scheme part of the URI.

• uri: Pointer to the Uri structure.
• Returns the scheme part of the URI.

uriGetUserInfo

char *uriGetUserInfo(const struct Uri *uri);

Retrieves the user info part of the URI.

• uri: Pointer to the Uri structure.
• Returns the user info part of the URI.

uriGetHost

char *uriGetHost(const struct Uri *uri);

Retrieves the host part of the URI.

• uri: Pointer to the Uri structure.
