Metalama.Extensions.HtmlWriter

This package provides optional HTML code writing functionality for Metalama.

Installation

Add a reference to this package in your project:

<PackageReference Include="Metalama.Extensions.HtmlWriter" />

Features

When this package is referenced, Metalama can generate HTML output files showing the source code with syntax highlighting and diff visualization. This is useful for:

• Documentation generation
• Debugging aspect transformations
• Visualizing compile-time vs run-time code

Usage

Compile-time Pipeline

Enable HTML output in your project by setting the WriteHtml MSBuild property:

<PropertyGroup>
 <MetalamaWriteHtml>true</MetalamaWriteHtml>
</PropertyGroup>

Aspect Tests

Enable HTML output in aspect tests by adding a metalamaTests.json file to your test project:

{
 "WriteInputHtml": true,
 "WriteOutputHtml": true
}

Without this package, the WriteHtml feature and related test options will throw an error with a message indicating that the package needs to be installed.
