A command line tool for creating a Wasm smart contract and tests for use on the Casper network.
cargo casper is a Cargo subcommand which can be installed via cargo install:
cargo install cargo-casper
To install from the latest dev branch:
git clone https://github.com/casper-ecosystem/cargo-casper
cargo install cargo-casper --path=cargo-casper
To create a folder "my_project" containing a basic example contract and a separate test crate for the contract:
cargo casper my_project
This creates the following files:
my_project/
├── contract
│ ├── .cargo
│ │ └── config.toml
│ ├── Cargo.toml
│ └── src
│ └── main.rs
├── Makefile
├── rust-toolchain
├── tests
│ ├── Cargo.toml
│ └── src
│ └── integration_tests.rs
└── .travis.yml
To build the contract, the correct version of Rust must be installed along with the Wasm target:
cd my_project
make prepare
The contract can now be built using:
make build-contract
and will be built to my_project/contract/target/wasm32-unknown-unknown/release/contract.wasm.
Running the test will automatically build the contract in release mode, copy it to the "tests/wasm" folder, then build and run the test:
make test
