RhinoCommon into VS interactive console

kitjmv · October 18, 2020, 4:45pm

Hello,

I regularly use the C # interactive console to test an expression.
but i can’t access any features outside of .NET libraries.

May be a licensing issue.

Do you have an idea?

Thank, jmv.

Hi @kitjmv,

RhinoCommon is dependent on Rhino (e.g. Rhino.exe). Thus, if Rhino is not running, most RhinoCommon methods will not be accessible.

I haven’t tried this yet, but I would imagine this would work with Rhino.Inside and V7

Hello @dale
unfortunately, even with Rhino running (inside VS in debug mode or not) the result is the same.
Hello @stevebaer
I have concluded that a VS extension with “Rhino.Inside” can provide an interactive console for Rhino. but I don’t know how to write a VS extension.
I was hoping to find a solution here
thanks to you two

Can you reference a nuget package? If so, you can try referencing Rhino.Inside at
https://www.nuget.org/packages/Rhino.Inside/

I’m pretty confident this can be done, but haven’t personally had time to try and experiment with it. Here’s a .NET console app that uses Rhino.Inside which is what I think we can replicate in a REPL

github.com

mcneel/rhino.inside/blob/master/ConsoleApps/HelloWorld/Program.cs

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

using Rhino.Runtime.InProcess;
using Rhino.Geometry;

namespace HelloWorld
{
  class Program
  {
    #region Program static constructor
    static readonly string SystemDir = (string) Microsoft.Win32.Registry.GetValue
    (
      @"HKEY_LOCAL_MACHINE\SOFTWARE\McNeel\Rhinoceros\7.0\Install", "Path",
      Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.ProgramFiles), "Rhino WIP", "System")
    );

    static Program()
    {

@stevebaer! It’s really simple !!

There is no need for the NuGet library, just a reference to the RhinoCommon.dll assembly. (and new RhinoCore())
Thanks for the links

Note: It is important to call rc.Dispose () before exiting VS or resetting the console. Otherwise, you have to restart the PC to reconnect. (before losing the variable rc)

There ya go! thanks for letting me know it works

kitjmv · October 19, 2020, 6:11pm

now I ask myself a question.
If new Rhino.Runtime.InProcess.RhinoCore () can integrate all the features of RhinoCommon into another process.
Why“Rhino.Inside” is necessary to integrate Rhino into our applications?

stevebaer · October 19, 2020, 6:14pm

Rhino.Inside sets up Rhino so it runs as a library inside of another process.

kitjmv · October 19, 2020, 7:17pm

Ok, I don’t understand the difference between VS REPL console and application console like your example.
but being able to test expressions without running Rhino will be of great help )

Since only one RhinoCore instance can be created, it would be useful to have this instance in a RhinoCore.Instance field. I keep losing her all the time.

stevebaer · October 19, 2020, 7:39pm

Can you use static in the REPL? static var rc = new RhinoCore();

kitjmv · October 19, 2020, 7:51pm

Yes we can, but that doesn’t really help. Static or non-static fields are cleaned with the console.
It’s not so bad, We initialize once in the morning and the console remains open until the evening …
you just don’t need to do a # reset

stevebaer · October 22, 2020, 3:36pm

I’m not familiar with the C# REPL in VS code. Can you explain the problem a little more to me?

kitjmv · October 22, 2020, 5:03pm

To be honest, I can’t. I don’t understand the behavior of the console.
That i know,

The REPL operates on a state machine and maintains this state in the internal structure.
It is compiled as a C # script. And the main loop is here: https://github.com/dotnet/roslyn/blob/master/src/Scripting/Core/Hosting/CommandLine/CommandLineRunner.cs#L227
Two consecutive calls to new RhinoCore () in the same REPL fail.
But two VS with its REPL can create a RhinoCore
sometimes if i reset the command line (hence the internal state machine) i cannot recreate a RhinoCore. Sometimes yes.

In the end, this is probably not the right method.
Don’t waste time just for me. When it works, it’s good. When that doesn’t work I open a Grasshopper script component.

We agree, we are talking about Visual Studio 2019 and not Visual Studio Code …
