interop in linux :feature request:

[bakuzen]

Interop works beautifully when the psi app is running in Windows (and I can interop with Linux modules in other languages) using zmq. However, I'd like to setup an app on a Linux box and it would be really helpful to have interop capabilities.

What specific issue are you running into? In the latest release, interop (Microsoft.Psi.Interop) as well as the core \psi runtime are .NET Standard libraries and are expected to work cross-platform (any mixture of Linux/Mac/Windows). Please let us know of roadblocks we can investigate.

It might be a version problem. Here's my command and the response:

>dotnet add package Microsoft.Psi.Interop Writing /tmp/tmpFbCiBD.tmp info : Adding PackageReference for package 'Microsoft.Psi.Interop' into project '/home/casey/psi_logger/psi_logger.csproj'. info : Restoring packages for /home/casey/psi_logger/psi_logger.csproj... info : GET https://api.nuget.org/v3-flatcontainer/microsoft.psi.interop/index.json info : OK https://api.nuget.org/v3-flatcontainer/microsoft.psi.interop/index.json 229ms error: Unable to find a stable package Microsoft.Psi.Interop with version error: - Found 5 version(s) in nuget.org [ Nearest version: 0.10.16.1-beta ] error: Package 'Microsoft.Psi.Interop' is incompatible with 'all' frameworks in project '/home/casey/psi_logger/psi_logger.csproj'.

Very strange! I can repro this. However, if I append a specific version it works: dotnet add package Microsoft.Psi.Interop -v 0.10.16.0-beta.

BTW, I just verified that the following works with both ends running under Ubuntu. Hopefully this works for you:

import zmq, json

socket = zmq.Context().socket(zmq.SUB)
socket.connect("tcp://localhost:12345")
socket.setsockopt(zmq.SUBSCRIBE, '')

while True:
   [topic, message] = socket.recv_multipart()
   j = json.loads(message)
   print "Message: ", repr(j['message'])

using System;
using Microsoft.Psi;
using Microsoft.Psi.Interop;
using Microsoft.Psi.Interop.Format;
using Microsoft.Psi.Interop.Serialization;
using Microsoft.Psi.Interop.Transport;

namespace Test
{
    class Program
    {
        static void Main(string[] args)
        {
            using (var p = Pipeline.Create())
            {
	        var gen = Generators.Range(p, 0, 1000, TimeSpan.FromMilliseconds(100));
                var sin = gen.Select(x => Math.Sin(x / 100.0));
                var mq = new NetMQWriter<double>(p, "sin-topic", "tcp://localhost:12345", JsonFormat.Instance);
                sin.PipeTo(mq);
                p.Run();
            }
        }
    }
}

That worked! Thank you!

(though I needed to use the same version for Microsoft.Psi.Runtime)

Glad it worked. I'm closing this issue, but please feel free to reopen it if you're still having trouble.
