pycall.rb VS TryRuby

Yeah, I know there are few libraries that do similar things: pycall.rb and rb_call, and there is also rubypython, but it's not supported and doesn't work with Python 3. I used pycall to create matplotlib charts from Ruby, it's great, and I'm gonna use part of its code, type conversion implementation, for example. But I don't think it's enough, it's like a one way bridge, I want more, I want to call Python from Ruby and Ruby from Python at the same time: create an Airfow PythonOperator, invoke Ruby code inside, store some value into XCom. What about rb_call, I don't like how it's implemented at all, it starts a separate process and serializes data using MessagePack RPC, so you can't use callbacks. It's not even possible to pass a Python object as an argument or call Ruby method that requires a block. And of course it's not effective.

I have build a rails app that uses openai gem and it's working very well. For more advanced things I am exploring Pycall: https://github.com/mrkn/pycall.rb to call python functions. Don't have any experience though.

I have use this before cool and easy also could run in heroku ()( for my case https://github.com/mrkn/pycall.rb

From docs. I was able to install matplotlib (without --pre):

We use https://github.com/mrkn/pycall.rb extensively to interface with python libraries. So far, the only problem we have is memory leaks in python, but we mitigated the problem by isolating the leaking parts in a separate process.

I want to recommend an interactive resource to someone new to programming.

Something like https://try.ruby-lang.org/, but for the terminal.

Most of the top hits on Google either seem to also dive into unnecessary history, scripting/Git, or are not interactive.

Ideas?

My advice is to spend half an hour (maybe split in 2 sessions) on try-ruby Nothing to download, no install, all in your browser. See if you like it and move on accordingly.

Additionally, two recommended books for mastering Ruby are “Eloquent Ruby” by Russ Olsen and “Ruby Programming for Beginners: An Introduction to Learning Ruby Programming with Tutorials and Hands-On Examples” by Nathan Metzler. Furthermore, aside from courses and books, other online resources are available for learning Ruby, such as Tutorialspoint and try.ruby-lang.org.

Try https://try.ruby-lang.org/ for half an hour to see if you get the hang of it.

Opal is used on https://try.ruby-lang.org/ (it is a static website, but the entire website is Ruby, no JavaScript: https://github.com/ruby/TryRuby/ )

ChatGPT can’t write working code very well. If all this seems beyond you, you might want to start with some Ruby fundamentals first. Try Ruby is a good starting point.

Like Ruby WASI, it allows you to run Ruby in a web browser, but it takes a different approach - it is, like JRuby, a complete reimplementation of Ruby. Unlike Ruby WASI, you don't have to ship the entire Ruby compiler - you just ship your code compiled to JavaScript along with (possibly) minimal Ruby runtime. You can compare and contrast both on a recently updated TryRuby website (which itself - is a 100% Ruby frontend application compiled with Opal!).
