Dechained Ready-to-play ink! playground

DRink! aims providing support for ink! developers.
It comes in two parts:
1. drink library, which provides a minimal Substrate runtime allowing for ink! contracts development together with a facade interface for interacting with it
2. drink-cli command line tool, which puts drink behind friendly TUI
Actually, there are already some great tools for local contracts development like substrate-contracts-node or swanky. However, they all rely on a running node, which is not always convenient. Especially in the early stage, when you want to quickly test your contract and don't want to bother with setting up a node, networking issues, block time, etc.
For testing purposes, ink! 4.x provides awesome framework, but in some complex cases it is still not enough. For example, working with multiple contracts with different environments is not possible yet. And still, unless you are working with off-chain execution, there's a node running behind the scenes.
We work with literally minimal sufficient architecture that allows for a fully functional ink! contract development.
The only thing we need is a Substrate runtime with a contract pallet.
Having put it into TextExternalities we are ready to deploy and interact with contracts.
It's just like working within pallet's unit tests.
You can use DRink in two ways.
```rust let mut sandbox = Sandbox::new().unwrap();
let contractbytes = fs::read("path/to/contract.wasm").unwrap(); let address = sandbox.deploycontract(contractbytes, computeselector("new"), Default::default()); let result = sandbox.callcontract(address, computeselector("foo")); ```
drink-cli command line toolWhen you run binary (cargo run --release) you'll see a DRink! TUI.
This is the default mode.
You can always enter it by pressing Esc key.
- press h to see list of available commands with their brief descriptions
- press q to quit TUI
- press i to enter drinking mode
This is the mode where you can interact with your environment.
- you have cd and clear bashish commands available
- build command will use your local cargo-contract tool to build a contract from the sources in the current directory
- deploy command will deploy a contract from the current directory
- by pressing Tab you can switch between all deployed contracts (with automatic directory change)
- call command will call a contract with the given message
- next-block command will advance the current block number
- add-tokens command will add tokens to the given account
