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.

Make sure to check out the other examples too! 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.
