Sejong Buffer

Sejong Buffer is a buffer that receives ASCII bytes from standard English keyboard and sends out UTF-32 Hangul string. This buffer allows deletion by Jamo.

This rust library can be compiled as a WASM library or as part of another rust program.

USE

To use as an NPM package

Do NOT run in a node app, this package can only run in browser

Install: npm install sejong-buffer

In apps that built with webpack:

```js import('sejong-buffer').then(buffer => { buffer.put('d'); buffer.put('k'); buffer.put('s'); buffer.put('s'); buffer.put('u'); buffer.put('d');

console.assert(buffer.to_string() === '안녕');

buffer.put('s');
console.assert(buffer.to_string() === '안녕ㄴ');

buffer.pop();
console.assert(buffer.out() === '안녕');
console.assert(buffer.out() === '');

}); ```

To use in Rust program

Install: cargo install sejong

```rust use sejong::{Buffer, Byte}; let mut buf = Buffer::default(); buf.put(Byte::NG as u8); buf.put(Byte::A as u8); buf.put(Byte::N as u8); buf.put(Byte::N as u8); buf.put(Byte::YEO as u8); buf.put(Byte::NG as u8);

asserteq!(buf.tostring(), "안녕");

buf.put(Byte::N as u8); asserteq!(buf.tostring(), "안녕ㄴ");

buf.pop(); asserteq!(buf.out(), "안녕"); asserteq!(buf.out(), ""); ```

BUILD

WASM

1. Install wasm-pack: curl https://rustwasm.github.io/wasm-pack/installer/init.sh -sSf | sh
2. Build the wasm npm package: wasm-pack build --release -- --features wasm

rust lib

No additional step. Just use as regular rust library.
