Jupyter Notebooks

​

Getting Started

1. Install Visual Studio Code (VSCode)
2. Install the Jupyter Notebook extension in VSCode
3. Install the evcxr Rust Jupyter kernel with:
   cargo install --locked evcxr_jupyter
   evcxr_jupyter --install
   
4. Run the Create: New Jupyter Notebook command in VSCode
5. Click the Select Kernel button in the top right
6. Select Jupyter Kernel...
7. Select Rust by searching for Rust
8. Enter on the first line an import of the soroban-sdk dependency with the testutils feature enabled.
   :dep soroban-sdk = { version = "22.0.7", features = ["testutils"] }
   
9. Enter a contract. For example:
   use soroban_sdk::{contract, contractimpl};
   
   #[contract]
   pub struct Contract;
   
   #[contractimpl]
   impl Contract {
       pub fn add(x: u32, y: u32) -> u32 {
           x+y
       }
   }
   
10. Enter some code to create a Soroban environment, register the contract, and invoke it.

use soroban_sdk::{Env};

let env = Env::default();
let id = env.register(Contract, ());
let client: ContractClient = ContractClient::new(&env, &id);
client.add(&1, &2)

11. Click the play button to run the code.
