# `nwc`, a NanoWasm compiler

`nwc` is a command-line tool that takes a MVP WebAssembly file and appends
[NanoWasm custom sections](https://gitea.privatedns.org/xavi/nanowasm-design)
to it, so that NanoWasm-capable interpreters such as
[`nanowasm`](https://gitea.privatedns.org/xavi/nanowasm) can consume them.

## Building from source

`nwc` only requires a C99 environment to build. The build system is based on
CMake and can be configured using the conventional process in CMake projects:

```
cmake -B build
```

Then, build with:

```
cmake --build build/
```

## Usage

The command below shall generate a NanoWasm-compatible file given by `out`
from a MVP WebAssembly file given by `infile`:

```
nwc <infile> <outfile>
```

Take into account that `infile` **must not** contain any NanoWasm custom
sections.
