bitsy-parser

a library for parsing Bitsy game data.

the version number follows Bitsy itself, so version 0.65.* targets Bitsy 6.5.

how to use

this sample program converts the player avatar to a smiley face.

extern crate bitsy_parser;
use std::{env, fs};
use bitsy_parser::game::Game;
use bitsy_parser::image::Image;

/// replaces the player avatar with a smiley face.
fn main() {
    let input_file = env::args().nth(1)
        .expect("No input path specified. Usage: `smiley infile outfile`");
    let output_file = env::args().nth(2)
        .expect("No output path specified. Usage: `smiley infile outfile`");

    let mut game = Game::from(fs::read_to_string(input_file).unwrap());

    game.avatar.animation_frames = vec![
        Image {
            pixels: vec![
                0,0,1,1,1,1,0,0,
                0,1,1,1,1,1,1,0,
                1,1,0,1,1,0,1,1,
                1,1,0,1,1,0,1,1,
                1,1,1,1,1,1,1,1,
                1,1,0,1,1,0,1,1,
                0,1,1,0,0,1,1,0,
                0,0,1,1,1,1,0,0,
            ]
        }
    ];

    fs::write(output_file, &game.to_string())
        .expect("Failed to write to output file");
}

some more practical uses would be things like:

• remove duplicate tiles
• merge two Bitsy games together
• programmatically create Bitsy games
• a Bitsy game editor

todo

failing tests

test_room_from_string shows an unexpected ordering for the items in the output of room::to_string

tidy up

• refactor the more shonky bits to idiomatic rust
