# 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.
|
|
```rust
|
|
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 game data specified. Usage: `invert infile outfile`");
|
|
let output_file = env::args().nth(2)
|
|
.expect("No game data specified. Usage: `invert 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
