MoveVM for Substrate

This is a modified MoveVM fork for the use of MoveVM in the pallet-move Substrate repo. Please check the pallet-move repository to learn more about this project.

Requirements

smove is a package manager for Move language in Substrate. Follow the instructions to install it.

Development

For the initial development setup, run the script:

./scripts/dev_setup.sh -ypt

Design

pallet-move uses the move-vm-backend to interact with the MoveVM.

The integral part of MoveVM functionality still lies within the language directory and contains only the necessary modifications which make the MoveVM operable within the Substrate framework.

Testing

To run tests for the MoveVM implementation, execute:

cargo test

To run tests for the move-vm-backend implementation, execute:

cargo test -p move-vm-backend --features build-move-projects-for-test # the `backend` main crate
cargo test -p move-vm-backend-common --features build-move-projects-for-test # helper crate for interaction with smove and pallet-move
cargo test -p move-vm-support # helper crate for interaction with language directory

Note: the feature flag build-move-projects-for-test needs to be provided only once in order to build all the necessary move-vm-backend/tests/assets/move-projects/ projects for test purposes (with the smove-build-all.sh script). Also, the feature flag needs to be provided whenever any of those Move projects are modified.

Open / Planned Points

• clean clippy warnings for the latest rustc compiler
• improve get_resource API (input params and the output value)
