The Fig standard library provides essential functions for performing common tasks, such as string manipulation, memory management, and I/O operations. This document outlines the available functions and their usage.

I/O Functions​

Prints a string to the standard output.

Prints a single character to the standard output.

Prints an integer to the standard output.

Prints a floating-point number to the standard output.

read_file(path: char[]): char[]​

Reads the contents of a file and returns it as a string.

Memory Management​

malloc(size: i32): i32[]​

Allocates a block of memory of the specified size and returns a pointer to the allocated memory.

String Manipulation​

len(str_ptr: char[]): i32​

Returns the length of a null-terminated string.

copy_str(str: char[]): char[]​

Creates a copy of a null-terminated string.

cmp_string(lhs: char[], rhs: char[]): bool​

Compares two null-terminated strings and returns true if they are equal, false otherwise.

add_string(lhs: char[], rhs: char[]): char[]​

Concatenates two null-terminated strings and returns the resulting string.

Example Usage​

import std;

fn main() {
    let l = len("Hello, World!");
    print_int(l);
}
