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

a simple example program:

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

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

• test for bitsy 7.0 and implement new features
  • titles can have multiple lines of dialog
  • dialogue names
• implement Result return types on ::from functions so we can handle errors
• handle old out-of-bounds editor errors (extra image pixels, exits/endings with position -1,-0 etc.)
  • it's ok if the output of these does not match the input as we're fixing it
• "unquote" function for dialogues, game title, anything else that supports """
• add Bitsy HD and Bitsy 7.0 test data
• fix variables/endings becoming "DLG DLG"?
• replace Image with Vec or something. seems like a pointless abstraction

tidy up

• refactor the more shonky bits to idiomatic rust
