c-cuid

A C Port of the collision-resistant id generator cuid.

Features

This library provides all the four functions as the original cuid
char* cuid(char* buff) writes a new null terminated cuid into given buffer (buffer size must be atleast CUID_LENGTH which is 26 bytes in order to fit the cuid)
char* slug(char* buff) writes a new null terminated slug ranging from 7 to 10 characters long into given buffer (buffer size must be atleast SLUG_LENGTH which is 11 bytes in order to fit the slug)
_Bool isCuid(char* buff) checks if given buffer is a valid cuid (returns 1 if yes, 0 if no)
_Bool isSlug(char* buff) checks if given buffer is a valid slug (returns 1 if yes, 0 if no)

Usage

You could use the library as follows

#include <stdio.h>
#include "c-cuid.h"
int main(){
	char cuidTest[CUID_LENGTH];
	char slugTest[SLUG_LENGTH];
	cuid(cuidTest);
	slug(slugTest);
	printf("CUID: %s\nisCuid: %s\nSLUG: %d\nisSlug:%d\n", cuidTest, slugTest, isCuid(cuidTest), isSlug(slugTest));
	// output (for example):
	// CUID: clb411w4100003s4f6y437nbt
	// isCuid: 1
	// SLUG: 632434s4 
	// isSlug: 1
}

Testing

You could run the test.sh or the test.bat to test if the library will work on your device If there's an error in compilation or unintended behaviour make an issue, or a pull request if you know how to fix it

Planned features

• Adjusting and Testing for macOS (i don't have a mac, so if you have one you could do that and do a pull request I will review it as soon as possible)
