Major Feature

Problem

Posit User Feedback: I understand that the two are similar and they can be converted manually. But we have many dissimilarities as well, along with python’s own added nuisances like indentations, positional args cannot come before named args…, differenced in datatypes, many packages are not available or are under a different name etc. etc.

Since we have a lot of applications that were built in last 6-7 years, spending time to manually convert each one of them is not an option for us.

Python has more support from Docker and Cloud providers, provides Gen AI integration.

Solution

Posit User Feedback: Please think about this functionality, it would be really good to have a tool to interconvert the code from R Shiny to Python Shiny.

It would be great to have an official prompt for this; but also, I'd be curious how well something claude code would do out-of-the-box, just by saying something to the effect of: I have a R Shiny app in dir 'foo'; please convert it to a Shiny for Python app.

Also, in case it helps, you might find shiny assistant's Python prompt to be a useful reference for providing instructions on certain stylistic preferences https://github.com/posit-dev/shiny-assistant/blob/main/shinyapp/app_prompt_python.md
