Included are:
- WAST -> Lean -> Binary parser.
- A Lean Webassembly runtime.
- A Lurk Webassembly runtime via Yatima language.
- Binary ouptuts are compatible with other Webassembly implementations.
First we'll clone cognivore/2022-12-08/yatimise branch.
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.
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!
lake build.
lake build.
Build lspec: lake build lspec.
Run tests with ./lean_packages/LSpec/build/bin/lspec.
