# CurlyWas
|
|
|
|
CurlyWas is a (still WIP) curly-braces, infix synatx for WebAssembly.
|
|
The goal is to have as to a 1:1 mapping to the resulting wasm instructions
|
|
as possible while still being reasonably convenient to write.
|
|
|
|
For this reason alone (and in no way because I'm a little lazy) does this
|
|
compiler not implement any optimizations except for constant folding.
|
|
|
|
## Example
|
|
|
|
```rust
|
|
import "env.memory" memory(4);
|
|
import "env.sin" fn sin(f32) -> f32;
|
|
|
|
export fn tic(time: i32) {
|
|
let i: i32;
|
|
loop screen {
|
|
let lazy t = time as f32 / 2000 as f32;
|
|
let lazy o = sin(t) * 0.8;
|
|
let lazy q = (i % 320) as f32 - 160.1;
|
|
let lazy w = (i / 320 - 120) as f32;
|
|
let lazy r = sqrt(q*q + w*w);
|
|
let lazy z = q / r;
|
|
let lazy s = z * o + sqrt(z * z * o * o + 1 as f32 - o * o);
|
|
let lazy q2 = (z * s - o) * 10 as f32 + t;
|
|
let lazy w2 = w / r * s * 10 as f32 + t;
|
|
let lazy s2 = s * 50 as f32 / r;
|
|
i?120 = max(
|
|
0 as f32,
|
|
((q2 as i32 ^ w2 as i32 & ((s2 + t) * 20 as f32) as i32) & 5) as f32 *
|
|
(2 as f32 - s2) * 22 as f32
|
|
) as i32;
|
|
branch_if (i := i + 1) < 320*240: screen
|
|
}
|
|
}
|
|
```
|
|
|
|
You can compile this to `technotunnel.wasm` with the command
|
|
|
|
```
|
|
curlywas technotunnel.cwa
|
|
```
|
|
|
|
Then run it on [MicroW8](https://exoticorn.github.io/microw8/v0.1pre2) |
