Anything on Pharo that would be like Opentalk on VW?

I am looking at some interprocess communication with Pharo. VW has Opentalk, VASt has Sst (I think, haven’t looked in a while). Does anything similar exist for Pharo?

I had the same quest. See the thread

Look at Seamless: https://github.com/pharo-ide/Seamless

Pretty powerfull - you are just using remote objects from another image like any other local object (proxying + serializing).

Hi Jerry,

We have worked on bridging Pharo with Python. It works remarkably well. Here is the website: https://objectprofile.github.io/PythonBridge/

We have also worked on a simple mechanism to distribute computation across multiple Pharo images. Here is the website: https://github.com/ObjectProfile/DMirror

Cheers,

Alexandre

Nice! How does the DMirror relate to the ImageWorker? https://github.com/pharo-contributions/ImageWorker

I do not know what is ImageWorker, but DMirror is a simple and efficient way to distribute a computation on single CPU.

Re: Anything on Pharo that would be like Opentalk on VW?

Sang did something similar a while ago too.

https://github.com/lxsang/SystemProcess

It allows an image to launch workers. One thing interesting is that they share virtual memory, so they can exchange data during the execution

Re: Anything on Pharo that would be like Opentalk on VW?

It would be nice to have one unified way for this *and* even think about shipping with that by default (so that we can use it e.g. for running tests.

Hi Alexandre,

How does usage of your Python bridge compare to Kilon's... ?

https://github.com/kilon/Atlas

No idea. But our bridge adequately manages errors crossing language boundaries and employ a set of command to enable promises. I am not sure sure whether Atlas was designed to do so.

Re: Python bridges

I know a little Kilon’s bridge as I used it as backend for Python3Generator [1] in the beginning.

To my understanding , the difference is that Atlas is lower-level than PythonBridge.

Basically, Atlas allows one to send python string and get back the returned value if it is a primitive type (int, float, str, etc).

PythonBridge uses Python3Generator as DSL to build valid Python code. Atlas expects regular Pharo’s string.

PythonBridge provides debugging facilities, Atlas does not to my knowledge.

PythonBridge provides facilities to map Pharo classes to Python classes, Atlas does not.

Cheers,

Julien
