# 半分
hanbun is a library for drawing half blocks (▀ and ▄) to the terminal.
This makes various kinds of graphics possible.
## Example
Here is an example that makes use of common features
such as creating a buffer, setting colored half blocks, printing text
and finally drawing the buffer to the screen.
```rust
use hanbun::{self, Color};
fn main() {
// Let's draw these two kanji on the screen using half blocks!
let lines = [
" W W W W W",
" W W W W W",
" W W W",
" WWWWWWWWW W W",
" W W W",
" W WWWWWWWWW",
"WWWWWWWWWWW W W",
" W W W",
" W W W",
" W W W W",
" W WW W",
];
// We need a buffer to store the state of each cell
let width = lines.iter().map(|line| line.len()).max().unwrap();
let height = lines.len() / 2 + 2;
let mut buffer = hanbun::Buffer::new(width, height, ' ');
let mut x = 0;
let mut y = 0;
for line in &lines {
for char in line.chars() {
// We set a colored half block for each W we find
if char == 'W' {
buffer.color(x, y, Color::Green);
}
// Advance to the right
x += 1;
}
// New line
y += 1;
x = 0;
}
// Add some centered text to the bottom
let text = "hanbun";
buffer.print(width / 2 - text.len() / 2, height + 5, text);
// Actually display what we've drawn
buffer.draw();
}
```
The result:
Results may vary depending on the terminal.

You can clone this repository and run examples
like the calculator using `cargo run --example calculator`.
## Footnotes
This is my first Rust library to make some crate development experience.
