CS-Script

This repository is a resting place for the obsolete codebase targeting .NET Framework. The releases after May 30, 2020 target .NET Core/5.

All main stream releases are available from https://github.com/oleg-shilo/cs-script/releases

This repository is only intended for hosting the historical codebase and potential branched/parallel releases for .NET Framework even though the chances for such releases are very small.

CS-Script is a CLR based scripting system which uses ECMA-compliant C# as a programming language.

CS-Script is one of the most mature C# scripting solutions. It became publicly available in 2004, just two years after the first release of .NET. And it was the first comprehensive scripting platform for .NET

CS-Script supports both hosted and standalone execution model. This makes it possible to use the script engine as a pure C# alternative for PowerShell. As well as extending .NET applications with C# scripts executed at runtime by the hosted script engine.

CS-Script allows seamlessly switching underlying compiling technology without affecting the code base. Currently supported compilers are Mono, Roslyn and CodeDOM.

CS-Script also offers comprehensive integration with most common development tools:

• Visual Studio,
• VSCode,
• Sublime Text 3,
• Notepad++.

It can be run on Win, Linux and Mac. And it is compatible with .NET, Mono and .NET Core.

Over the long history of CS-Script it has been downloaded through Notepad++ x86 plugin manager alone over times (see stats).

* statistics does not include x64 downloads nor downloads after Notepad++ discontinued shiping editor with the plugin manager x86 included

For the all CS-Script details go to the project Documentation Wiki.

For the roadmap for .NET 5 development see this article.

The following is a simple code sample just to give you the idea about the product:

Executing script from shell

Updating media file tags. Note, the script is using optional classless layout.

Script file: mp4_retag.cs

//css_nuget taglib
using System;
using System.IO;

string source = @"\\media-server\tv_shows\Get Smart\Season1";

void main()
{
    foreach (string file in Directory.GetFiles(source, "*.mp4"))
    {
        string episode_name = Path.GetFileNameWithoutExtension(file);

        var mp4 = TagLib.File.Create(file);
        mp4.Tag.Title = episode_name;
        mp4.Save();

        Console.WriteLine(episode_name);
    }
}

Execute script file directly in cmd-prompt without building an executable assembly:

C:\Temp>cscs mp4_retag.cs

Hosting script engine

dynamic script = CSScript.LoadCode(
                           @"using System.Windows.Forms;
                             public class Script
                             {
                                 public void SayHello(string greeting)
                                 {
                                     MessageBox.Show(""Greeting: "" + greeting);
                                 }
                             }")
                             .CreateObject("*");
script.SayHello("Hello World!");

                                             return a * b;
                                         }");

                          {
                              MessageBoxSayHello(greeting);
                              ConsoleSayHello(greeting);

                          {
                              MessageBox.Show(greeting);
                          }
                          static void ConsoleSayHello(string greeting)
                          {
                              Console.WriteLine(greeting);
                          }")
                         .GetStaticMethod("*.SayHello" , ""); 
SayHello("Hello again!");
