riichi-hand-rs

A collection of utilities for working with Riichi Mahjong player hands to use with Rust programming language.

This currently includes:

• Hand representation object
• Parser that allows to quickly create a hand using human-readable string, such as 123m456p_7*77z
• Renderer that allows to draw a hand to a raster image (along with a few ready-to-use sets of tile images)
• Points calculator (i.e. scoring table and an ability to calculate Aotenjou points with optional BigInt support)

Usage

Add the following to your Cargo.toml:

[dependencies]
riichi_hand = "0.6.3"

On the feature flags overview, please refer to the crate documentation.

Example

use riichi_hand::parser::HandParser;
use riichi_hand::raster_renderer::fluffy_stuff_tile_sets::YELLOW_FLUFFY_STUFF_TILE_SET;
use riichi_hand::raster_renderer::{RasterRenderer, RenderOptions};

fn main() {
    let hand = HandParser::parse("123m123p123sEESS").unwrap();
    let image = RasterRenderer::render(&hand, &*YELLOW_FLUFFY_STUFF_TILE_SET, RenderOptions::default());
    image.save("/tmp/hand.png").unwrap();
}

This results in the following image being generated:
