## Kurt demo project

live at [untitled-app.kittycad.io](https://untitled-app.kittycad.io/)

Not sure what to call this, it's both a language/interpreter and a UI that uses the language as the source of truth model the user build with direct-manipulation with the UI.

It might make sense to split this repo up at some point, but not the lang and the UI are all togther in a react app

## To run, there are a couple steps since we're compiling rust to WASM, you'll need to have rust stuff installed, then

```
yarn install
```
then
```
yarn build:wasm
```
That will build the WASM binary and put in the `public` dir (though gitignored)

finally
```
yarn start
```

and `yarn test` you would have need to have built the WASM previously. The tests need to download the binary from a server, so if you've already got `yarn start` running, that will work, otherwise running
```
yarn simpleserver
```
in one terminal
and 
```
yarn test
```
in another.

If you want to edit the rust files, you can cd into `src/wasm-lib` and then use the usual rust commands, `cargo build`, `cargo test`, when you want to bring the changes back to the web-app, a fresh `yarn build:wasm` in the root will be needed.

Worth noting that the integration of the WASM into this project is very hacky because I'm really pushing create-react-app further than what's practical, but focusing on features atm rather than the setup.
