PackScan.Defaults 0.1.1

Package Data Retrieval & License Analyzer

This project provides tools for retrieving information about installed packages and their dependencies within your code. It allows you to retrieve comprehensive information about installed packages, including dependencies, and generates code to access this data. The included analyzer helps you ensure license compliance by identifying packages with disallowed licenses.

Additionally, these tools offer optional configurations to generate code that provides access to icons, license texts, ReadMe content, release notes, and other package information. You can include these additional resources based on your specific needs.

Currently, the project only supports C#, but it is designed in a way that allows for future support of VB.NET or F#.

Key Features

1. Generate Package Data:</br> Generate simple and easily accessible code to retrieve detailed information about the packages installed in your project. With this code, you can easily access package versions, dependencies, licenses, and other data.

2. Check License Compliance:</br> The included analyzer helps you ensure compliance with licensing requirements. Identify packages that contain licenses not compatible with your project or company policies, enabling you to address potential licensing issues early on.

3. Customizable Configuration:</br> Tailor the behavior of the tool to perfectly match your requirements. Adjust the configuration to change how package contents are loaded, code is generated, and license analyses are performed.

4. Seamless Project Integration:</br> The project can be seamlessly integrated into your existing projects. Install the required NuGet packages and configure the settings accordingly. Accessing package data and license information is straightforward through the generated code.

5. Possible Use with CI/CD:</br> The .NET Tool allows integration into CI/CD processes, automating package analysis and management in your continuous integration and deployment workflows.

PackScan.Tool

The .NET Tool provides integration into CI/CD processes and supports different ways of depositing content files.

PackScan.Analyzer

The Analyzer can be configured directly in your project and supports checking which packages and licenses are allowed.

Installation

Analyzer

Install the analyzer:

dotnet add package --prerelease PackScan.Analyzer

Additionally, you need to install the following package in all projects where you want to use the code:

dotnet add package --prerelease PackScan.PackagesProvider.Abstractions

.NET Tool

Install the .NET Tool:

dotnet tool install --prerelease --global PackScan.Tool

It is also necessary to install the following package to enable all configuration features:

dotnet add package --prerelease PackScan.Defaults

Additionally, you need to install the following package in all projects where you want to use the code:

dotnet add package --prerelease PackScan.PackagesProvider.Abstractions

Generated Result

The generated code allows you to retrieve package information wherever needed in your code. You can also configure the license analyzer to enforce license compliance.

Here's how you can use the generated code:

var serilog = Packages.GetPackageById("Serilog");

foreach (var package in Packages.GetPackages())
{
    Console.WriteLine($"{package.Id} | {package.Version.Value} | {package.License?.Expression}");
}

// or with an instance

IPackagesProvider instance = new Packages();

var serilog = instance.GetPackageById("Serilog");

foreach (var package in instance.GetPackages())
{
    Console.WriteLine($"{package.Id} | {package.Version.Value} | {package.License?.Expression}");
}

// or with dependency injection

var services = new ServiceCollection()
    .AddSingleton<IPackagesProvider, Packages>()
    .BuildServiceProvider();

var packagesProvider = services.GetRequiredService<IPackagesProvider>();
var serilog = instance.GetPackageById("Serilog");

foreach (var package in instance.GetPackages())
{
    Console.WriteLine($"{package.Id} | {package.Version.Value} | {package.License?.Expression}");
}

Configuration

Both the .NET Tool and the Analyzer offer similar configurations, but there are differences due to technical reasons. The following descriptions outline all the settings and specify whether and how they can be utilized for each respective option.

Enums

Content Write Mode

The package data contains references to various files or websites whose content can be loaded. To specify how the loaded content should be provided, you can choose from the following options:

• Embed: Treat the files as embedded resources.
• InCode: Write the content of the files in code and compile them.
• File: Copy the files to the output directory and read them from there.

Content Load Mode

The package data contains references to various files or websites whose contents can be loaded. However, loading the data can be slow. You can specify how the data should be loaded using the following values:

• None: Do not load any data.
• PreferUrl: Preferentially load the website content if a URL is specified. If no URL is specified, search for a file.
• PreferFile: Preferentially load the file content if a file is specified. If no file is specified, search for a URL.
• OnlyUrl: Load only the content of the file. Do not load website content.
• OnlyFile: Load only the content of the website. Do not load file content.

Future?

Currently, the project only supports C#. However, it is designed in a way that allows for future support of VB.NET or F#. The ability to read package data or generate code as a separate package is not currently available, but the project is designed with the flexibility to release separate packages for these functionalities in the future.
