Using the Haskell Editor

As an experienced Haskell developer you can use the Haskell editor to render Marlowe code. Marlowe is written as a Haskell data type, and thus it is straightforward to generate Marlowe smart contracts using Haskell.

To use the Haskell editor follow these steps:

  1. Open the Marlowe Playground.

  2. Click Start coding!

  3. Select the Haskell version from the menu.

    You will see a window like this:


  1. Now you can start coding in Haskell.

    Alternatively, you can use some example contracts to work with.

  2. Describe a contract in the editor. For this, define a top-level value contract of type Contract, add conditions, and close the contract.

    The following window will open for an Escrow contract:


  1. Click Compile to convert this value from Haskell into Marlowe.

  2. Then, click Send to Simulator.

    The Simulator allows you to simulate Marlowe contracts transaction by transaction. You can find more instructions on how to use the Haskell editor in the Marlowe tutorial.
