# Wasm tools for lean
Included are:
* WAST -> Lean -> Binary parser.
* A Lean Webassembly runtime.
* [A Lurk Webassembly runtime](https://github.com/yatima-inc/Wasm.lean/tree/cognivore/2022-12-08/yatimise) via [Yatima language](https://github.com/yatima-inc/yatima-lang).
* Binary ouptuts are compatible with other Webassembly implementations.
## Lurk runtime demo
First we'll clone `cognivore/2022-12-08/yatimise` branch.
```bash
git fetch --all
git checkout cognivore/2022-12-08/yatimise
```
Optionally, let's clean whatever possible artefacts and compiled dependencies. A poor person's reproducible builds.
```bash
lake clean
rm -rf lean_packages/*
```
Now let's `build` everything!
```
lake build
```
Awesome, now let's run the Wasm lean expression.
```
lake exe yati_raw
```
You should get a number as the result of this call.
Now build `lurk` and install it into a place in your `PATH`:
```
cd /tmp
git clone https://github.com/lurk-lang/lurk-rs.git
cd lurk-rs
git checkout 11a29cb723a49b442907cdeb1e09e6a5729742a7
cargo build
cargo install --path .
```
The install part installs binaries into `~/.cargo/bin`.
Do the same with `yatima-lang`:
```
cd /tmp
git clone https://github.com/yatima-inc/yatima-lang.git
cd yatima-lang
git checkout a6671e54b361e0f3d4c954803524762aee0f30f5
lake build
cp build/bin/yatima ~/.cargo/bin/
```
Now we can go back to the root directory of `Wasm.lean` project and run the following command:
```
yatima transpile Yati32Raw.lean -d=go -rs
```
This command tells the system that you want to run in Lurk function named `go` from the Lean file (!) called `Yati32Raw.lean`.
The last flag `-rs` means "use the reference Rust implementation of Lurk". Let's try out with our implementation!
```
yatima transpile Yati32Raw.lean -d=go -rs
```
As you see, all three times, the resulting number was the same. It has a special meaning, by the way, see if you can crack it!
If you could, send your answer to @cognivore over at Yatima Zulip to claim your bragging rights!
## Develop
`lake build`.
## Build
`lake build`.
## Test
Build `lspec`: `lake build lspec`.
Run tests with `./lean_packages/LSpec/build/bin/lspec`.
