Getting Started

This is an example of how you may give instructions on setting up your project locally. To get a local copy up and running follow these simple example steps.

Prerequisites

1. Download .NET Core 3.1 from here.
2. Download Git from here.

Installation

1. Clone the repo

   git clone https://github.com/ryanfalzon/DLT-Dissertation

2. Build the UnifiedModel.SourceGenerator project

   cd Dissertation/src/UnifiedModel/UnifiedModel.SourceGenerator
   dotnet build --output "c:/UnifiedModel/SourceGenerator"

3. Build the UnifiedModel.Connectors project

   cd Dissertation/src/UnifiedModel/UnifiedModel.Connectors
   dotnet build --output "c:/UnifiedModel/Connectors"

4. Run the UnifiedModel.SourceGenerator.exe executable

   UnifiedModel.SourceGenerator.exe "UnifiedCode.txt" "OutputDirectory"

5. Once generated smart contracts are deployed, fill in the Ethereum.json file created in the output directory of step 3

   {
    "PublicKey": "",
    "PrivateKey": "",
    "Contracts": [
      {
        "Name": "",
        "AbiLocation": "",
        "Address": ""
      }
    ]
   }

6. Copy the contents of the output directory of step 3 to the location where the desktop code will be running

Framewok Usage

This is an example of how the framework can be used to create annotated code to be compiled down to C# and Solidity code for Desktop and Etheruem enviornments.

[XOn(All)]
public class Profile : XModel("SocialNetwork")
{
  ...
}

[XOn(Ethereum)]
public class SocialNetwork
{
  ...
}
  
[XOn("All")]
public class SocialNetwork
{
  public void Register(Profile profile)
  {
    @XOn("Desktop", profile)
    {
      ...
    }

    ~@XOn("Ethereum", profile)
    {
      ...
    }
  }
}
