Interfaces

Since 19.1, TOMAS uses a modular interface design for writing and executing programs. At the moment, the operating system doesn't yet support loading assemblies that would take advantage of this API, but it is being looked into.

Design

IProgram is used to create the actual program while IShell executes the respective program from a dictionary. While still early in development, the approach has allowed for easy migration from one major release of COSMOS to another with little to no modifications of the code itself.

public interface IProgram
{
    string Name { get; }

    string Description { get; }

    bool Entry(IShell shell, IEnumerable<KeyValuePair<string, object>> arguments);
}

public interface IShell
{
    string ReadLine { get; }

    Dictionary<string, IProgram> Programs { get; }

    IEnumerable<KeyValuePair<string, object>>? ParseArguments(IProgram program, string[] arguments);
}
