Setup with nix

First, set up your build environment by invoking

nix-shell ../shell.nix

This will open a new shell, where all the wasm tools and the appropriate rust version are available.

Manual setup

In addition to the general scasm environment (like a Rust compiler), you also need the wasm-opt and wasm2wat programs. These are found on most platforms in the binaryen and wabt packages.

Alas in Ubuntu this is a problem so we used the script ./install-wasm-tools.sh in this directory.

Running tests

Now, run

./run_on_all_demos.sh

to convert all the demos in scale/demos from Rust to scale assembly.

The resulting .asm file is in textual asm form, so if you want to have the binary format, you need to invoke

cargo run --manifest-path ../Assembler/Cargo.toml -- --optimization-level 1 scale/demos/your_demo/scale_assembly.asm output_byte_code_file.bc

Creating a new demo/test

Run

./create_new_test.sh you_test_name

which will create a fully functioning new test in scale/demos that will automatically be run when you run ./run_on_all_demos.sh.
