xwords-rs's Introduction

xwords

xwords is a fast library that fills crossword puzzles. This repo also contains a lightweight CLI for invoking the library.

Caveat Emptor

This is foremost a hobbyist project for me to learn a bit about profiling and optimizing rust. I am more than happy to accept contributions or to consider feature requests, but please be aware that the future of this project is somewhat uncertain.

CLI

This command fills a grid that is stored in a local file using a default wordlist.

Library

use xwords::{crossword::Crossword, fill_crossword_with_default_wordlist};

fn main() -> Result<(), String> {
    let empty_crossword = Crossword::new(String::from(
        "

    let filled_crossword = fill_crossword_with_default_wordlist(&empty_crossword)?;
    println!("{}", filled_crossword);
    Ok(())
