Basilisque - Code Analysis

Overview

This project provides helpers for writing .Net code analyzers and source generators.

Description

This project contains helpers and structured classes, that support you in generating source code that is syntactically correct and well formatted. It also contains helpers for unit testing source generators.

For example this code...

private string generateMyDemoMethod()
{
    var classInfo = new ClassInfo("MyDemoClass", AccessModifier.Public);
    classInfo.GenericTypes.Add("T1", (new List<string>() { "class", "new()" }, "Description of T1"));
    classInfo.GenericTypes.Add("T2", null);
    classInfo.Methods.Add(new MethodInfo(AccessModifier.Public, "bool", "MyDemoMethod")
    {
        Parameters =
        {
            new ParameterInfo(ParameterKind.Ordinary, "int", "myMaxParam")
        },
        Body =
        {
            @"
// this is the method body. You can write any code in here...
var r = System.Random.Shared.Next(myMaxParam);
if (r > 5)
    return true;
else
    return false;
"
        }
    });

    return classInfo.ToString();
}

...will result in this output:

/// <summary>
/// MyDemoClass
/// </summary>
/// <typeparam name="T1">Description of T1</typeparam>
/// <typeparam name="T2"></typeparam>
[global::System.CodeDom.Compiler.GeneratedCodeAttribute("My.Demo.SourceGenerator", "1.0.0.0")]
[global::System.Diagnostics.DebuggerNonUserCodeAttribute()]
[global::System.Runtime.CompilerServices.CompilerGeneratedAttribute()]
public class MyDemoClass<T1, T2>
    where T1 : class, new()
{
    public bool MyDemoMethod(int myMaxParam)
    {
        // this is the method body. You can write any code in here...
        var r = System.Random.Shared.Next(myMaxParam);
        if (r > 5)
            return true;
        else
            return false;
    }
}

There is support for namespaces with usings, classes, properties, methods and fields with matching support for XML code documentation, generics and extension methods.

In addition there are some helpers for registering the generated source in an incremental source generator. They will automatically provide you with information about the used language, the language version and the nullable context.

You don't have to care about the order in that you specify the code parts. The generated source code will always be well structured and correctly indented.

For details see the wiki.

Installation for Code Analyzers and Source Generators

Install the NuGet package Basilisque.CodeAnalysis.
Installing the package will automaticall configure your project to be packed as code analyzer/source generator. It will also pack its own assemblies beside your analyzer/generator as dependency.

So you're ready to get started.

Installation for Unit Tests

This project currently provides helpers for MSTest, NUnit and XUnit.
So you have to install the correct package for the test framework you're using:
Basilisque.CodeAnalysis.TestSupport.MSTest
Basilisque.CodeAnalysis.TestSupport.NUnit
Basilisque.CodeAnalysis.TestSupport.XUnit

Now you can write your first Unit Test.
