Another wasm interpreter engine for gophers.

## Usage

### Executable

Install

```bash

go install github.com/c0mm4nd/wasman/cmd/wasman

```

```bash

$ wasman -h

Usage of ./wasman:

  -extern-files string

        external modules files

  -func string

        main func (default "main")

  -main string

        main module (default "module.wasm")

  -max-toll uint

        the maximum toll in simple toll station

```

Example: [numeric.wasm](https://github.com/C0MM4ND/minimum-wasm-rs/releases/latest)

```bash

$ wasman -main numeric.wasm -func fib 20 # calc the fibonacci number

{

  type: i32

  result: 6765

  toll: 315822

}

```

If we limit the max toll, it will panic when overflow.

```bash

$ wasman -main numeric.wasm -max-toll 300000 -func fib 20

panic: toll overflow

goroutine 1 [running]:

main.main()

        /home/ubuntu/Desktop/wasman/cmd/wasman/main.go:85 +0x87d

```
