# wasm-tools
Boilerplate code to test Parity WASM tools and compile rust/c/c++ code to wasm-contracts
## How to compile contract
```
git clone https://github.com/NikVolf/wasm-tools
cd wasm-tools/runner
./build.sh <PATH TO C/C++/Rust source file>
./start.sh
```
and then open `http://localhost:8000`, specify input stream in `Input` input, press `Execute call` to run a contract `call` function, see storage update (if contract produced any) as well as `Result` stream (again, if contract produced any).
see `/samples` directory for sample contracts that are compiled this way
## Prerequisites
- Emscripiten for C/C++ (see [this page](http://kripken.github.io/emscripten-site/docs/getting_started/downloads.html), `emcc` should be in the `PATH`)
- Rust with `wasm32-unknown-emscripten` target (see [this instruction](https://hackernoon.com/compiling-rust-to-webassembly-guide-411066a69fde) to setup)
