How to create a programming language using C#

Hello guys this is me Genesis and I am going to teach you how to create a Programming Language using C#.

Well, the tool we are going to use is "Microsoft Visual C#" and download it in the Internet if you didn't have it yet.

Well, I am playing the codes just to put the following codes:

Console.ReadLine();

But I haven't see to it that I can't post that command in my project so let's get started.

Step 1: Creating a console application project

Here is the following step to create a Console Application project:
1. Go to File -> New Project.
2. Make sure you click "Console Application" and name whatever you want.
3. Click OK.

step 2: start typing the codes to create the project!

Here's what you see once you create your project:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace Eagle_Script
{
 class Program
    {
      static void Main(string[] args)
      {
      }
  }
}

Looks difficult where to start huh. Well, the "namespace Eagle_Script" in the codes is the name of the project that you have typed to create the project.

Add these codes just below "using System.Text;":

using System.IO;
using System.Reflection;
using System.Reflection.Emit;

Well, we're not getting closer but we are getting into it.

Below the second "{" which is just above the "static void Main(string[] args)", put in these codes:

static AssemblyName an;
static AssemblyBuilder ab;
static ModuleBuilder mb;
static TypeBuilder tb;
static _AppDomain ad;
static MethodBuilder meb;
static ILGenerator il;

OK so we are getting this clear so I want you to add these codes under the third "{":

ad = AppDomain.CurrentDomain;
an = new AssemblyName("lol");
ab = ad.DefineDynamicAssembly(an, AssemblyBuilderAccess.Save);
mb = ab.DefineDynamicModule("Lol", "idk.exe");
meb = tb.DefineMethod("main", MethodAttributes.Public | MethodAttributes.Static);
il = meb.GetILGenerator();
an.Name = "MyApp";
ab.SetEntryPoint(meb);

StreamReader sr = new StreamReader(args[0]);
string Code = sr.ReadToEnd();

//The codes below is the creation of our own syntax in its own command.
    foreach (string cmd in Code.Split('\n'))
    {
      if (cmd.StartsWith("print"))
      {
          il.Emit(OpCodes.Ldstr, cmd.Substring(6));
          il.Emit(OpCodes.Call, typeof(System.Console).GetMethod("Write", new System.Type[] { typeof(string) }));
      }
      if (cmd.StartsWith("println"))
      {
          il.Emit(OpCodes.Ldstr, cmd.Substring(8));
          il.Emit(OpCodes.Call, typeof(System.Console).GetMethod("WriteLine", new System.Type[] { typeof(string) }));
        {
    }
  }
  il.Emit(OpCodes.Ret);
  tb.CreateType();
  ab.Save(Path.GetFileNameWithoutExtension(args[0]) + ".exe");

OK, we're done! It is time to publish our work.

STEP 3: PUBLISH THE PROGRAMMING LANGUAGE

To publish your software, go to Build -> Publish in the Menu bar and publish according to the requirements.

step 4: test it!

In your notepad, type this:

print Hello
print World
println Lol!

Save it, then drag into the compiler which is in type .exe. that you have created (in the file of your programming language).
