RefleCS 0.1.0

RefleCS

Description

RefleCS is a library that sits in front of the Roslyn C# parser and makes it easier to create new or edit existing C# files that are outside of an Assembly context.

Though basic work is done, RefleCS is still missing some CS language features. If you encounter any, please file an issue.

Examples

Create new file

You can create a new file by creating an instance of CsFile and saving it via the CsFileHandler

var file = new CsFile(
    new List<Using>
    {
        new("System")
    },
    new Namespace(
        "MyApp",
        new List<Class>
        {
            new(
                new List<ClassModifier>
                {
                    ClassModifier.Public,
                    ClassModifier.Sealed
                },
                "App",
                new List<Constructor>(),
                new List<Property>(),
                new List<Method>
                {
                    new(
                        new List<Comment>(),
                        new List<MethodModifier>(),
                        "void",
                        "CheckIfTrue",
                        new List<Parameter>
                        {
                            new(
                                "bool",
                                "bl")
                        },
                        new List<Statement>
                        {
                            new("return bl;")
                        })
                },
                new List<BaseType>())
        }));

new CsFileHandler().SaveOrReplace(file, @"C:/Temp/mycsfile.cs");

This will create the following file content:

using System;

namespace MyApp;

public sealed class App
{
    void CheckIfTrue(bool bl)
    {
        return bl;
    }
}

However, after creation of a CsFile, it's still possible to edit classes, methods, etc. For example by adding a new parameterless constructor:

file.Nmsp.Classes.First()
    .AddConstructor(
        new Constructor(
            new List<ConstructorModifier>() { ConstructorModifier.Public },
            "App",
            new List<Parameter>(),
            new List<Statement>() { new("Console.WriteLine(\"Ctor called!\");") }
        ));

Edit an existing file

You can create a CsFile instance from an existing file in the file system

CsFile file = new CsFileHandler().FromPath(@"C:/Temp/mycsfile.cs");

or from C# code already loaded as a string

var csCode = @"using System;
namespace MyApp;
public class App {}";

CsFile file = new CsFileHandler().FromContent(csCode);

Then you can edit the CsFile and save it.

file.Nmsp.Classes.First()
    .AddConstructor(
        new Constructor(
            new List<ConstructorModifier>() { ConstructorModifier.Public },
            "App",
            new List<Parameter>(),
            new List<Statement>() { new("Console.WriteLine(\"Ctor called!\");") }
        ));

new CsFileHandler().SaveOrReplace(file, @"C:/Temp/mycsfile.cs");
