Multi Language Support in Interactive Window (Julia, Rust, CSharp, etc)

Workflow

• User has Julia kernel installed
• User installs our extension
• User opens Julia file & creates a cell marker using # %%
• Code lenses appear allowing user to run cell
• User runs cell (code) & interactive window appears
• Jupyter, Python, Python extension not required

Technical details

• Determine available kernels
• Based on available kernels, add support for cells code lenses in text editors
• Super easy to add support for julia, rust, csharp, fsharp, etc… (super easy changes to implement this feature)

Support Features

• Cell commands (run, run above, run below, add, insert, move, etc)
• Interactive window commands work
• Restart, interrupt, etc
• Basic Intellisense in prompt (comes from kernel - hence supported if kernel supports this)

Possible MVP

• No support for debugging
• No need of exposing APIs from extension
  • When other languages need features we can expose this API (debugging, variables, etc)
• Allow users to disable interactive window code lenses in other languages (if they dont need this)
• Via an experiment

Screenshots of prototype with it working in Julia, Rust, CSharp, fsharp

Thanks for expressing the interest in this feature, we haven’t prioritized this feature.

Just sending some ❤️ to this feature request… Looking forward to being able to use Rust’s Evcxr Jupyter kernel https://github.com/google/evcxr/tree/main/evcxr_jupyter 🥂
