Newdoku | docs.rs

Simple Sudoku solver written in Rust. Method is inspired by a method briefly outlined in a CS lecture I had that I decided to try and implement based only on my understanding from the lecture.

It is called Newdoku because I started doing this a while ago and forgot about it and decided to restart, hence "New"

Quick Start

Library

toml [dependencies] newdoku = { version = "0.6", default-features = false }

```rust use newdoku::Sudoku;

fn main() { let s = Sudoku::from_str( "xxxxxxx9xx9x7xx21xxx4x9xxxxx1xxx8xxx7xx42xxx5xx8xxxx748x1xxxx4xxxxxxxxxxxx9613xxx", ) .unwrap();

println!("{}\n\n{}", s, s.solution(0, false).unwrap());

} ```

See the docs for more info.

Binary

From source

console $ git clone https://github.com/Piturnah/newdoku $ cd newdoku $ cargo run

From crates.io

console $ cargo install newdoku $ newdoku

Options

console OPTIONS: -f, --file <FILE> Load Sudoku from file -h, --help Print help information -q, --quiet No output until finished solving (faster) -s, --step <STEP> Wait STEP millis between inserts [default: 0] -u, --uid <UID> Load Sudoku by unique ID

When loading from a file, the parser parses any digit as a number in the sudoku. Any other character other than a newline will be parsed as an empty square.

Example sudoku: xxxxxxx9xx9x7xx21xxx4x9xxxxx1xxx8xxx7xx42xxx5xx8xxxx748x1xxxx4xxxxxxxxxxxx9613xxx
