Getting started

This library require .NET 5 SDK or Visual Studio 16.8 or later because this library use Source Generators.

For library user

Use SourceExpander.Console

Install:

dotnet tool install -g SourceExpander.Console

Run:

# minimum run
dotnet-source-expand Sample/SampleProject2/Program.cs

# specified project
dotnet-source-expand Sample/SampleProject/Put.cs -p Sample/SampleProject2/SampleProject2.csproj

Use SourceExpander.Generator

see Sample or https://github.com/kzrnm/ac-library-csharp

Install-Package SourceExpander
Install-Package <A library with embedded source>

using System;
class Program
{
    static void Main()
    {
        SourceExpander.Expander.Expand();
        // Your code
    }
}

When you run the code, SourceExpander.Expander.Expand() create new file that combined library code.

using System;
class Program
{
    static void Main()
    {
        SourceExpander.Expander.Expand();
        // Your code
    }
}

#region Expanded by https://github.com/kzrnm/SourceExpander
namespace SourceExpander { public class Expander { [Conditional("EXPANDER")] public static void Expand(string inputFilePath = null, string outputFilePath = null, bool ignoreAnyError = true) { } public static string ExpandString(string inputFilePath = null, bool ignoreAnyError = true) { return ""; } } } 
// library code
#endregion Expanded by https://github.com/kzrnm/SourceExpander

For library developer

It's easy, just install SourceExpander.Embedder.

Install-Package SourceExpander.Embedder

Avoid embedding some type

Embedding is skipped for type that have SourceExpander.NotEmbeddingSourceAttribute.

Notes

Because SourceExpander.Embedder run at compile time, the embedded source code cannot be used in the same project.

Embedded data

SourceExpander.Embedder embed some data like below.
