# WASMonkey

The WASMonkey patches a WASM object file to replace a set of exported

functions with imported functions from another library.

## Usage

```text

USAGE:

    wasmonkey [FLAGS] [OPTIONS] --input  --output 

FLAGS:

    -n, --original-names    Use the original name as a key in the builtins map

    -h, --help              Prints help information

    -V, --version           Prints version information

OPTIONS:

    -B, --builtins-additional ...    Additional builtins function names to replace

    -b, --builtins                         Path to the builtins library

    -m, --builtins-map                 Path to the builtins map file

    -i, --input                               Path to the input file

    -o, --output                             Path to the output file

```

`builtins_file` is an object containing alternative implementations to

functions called in the wasm code.

Symbols starting with a `builtin_` prefix will be used for substitution.

For example, a `memmove()` function defined as an external in the WASM

object will be replaced by calls to an imported `builtin_memmove()`

function, if `builtin_memmove()` is present in the builtins file.

A JSON-encoded map of the performed substitutions can be optionally written

into `builtins_map_file`.
