This is a central place for all of our guest source code. It can be included in other maven projects as a test resources bundle.

If you want to add or edit guest modules for tests, you'll need to compile here. Add the program to the subfolder for the appropriate source language. Example: src/main/resources/rust.

You can use docker to compile everything. The run.sh script can orchestrate this for you:

cd wasm-corpus

# rebuild (or build image for first time)
./run.sh rebuild

# compile all the submodules
./run.sh

# compile just one folder
./run.sh rust

If you want to run on your host machine you can run the compile.sh subscript yourself. It has the same arguments (assumes you have WASI_SDK_PATH set for compiling c):

cd wasm-corpus/src/main/resources

# example
./compile.sh rust
