@anders_boje Yep, I think our Cursor rules duplication is already somewhat unnecessary since AGENTS.md are fully supported in Cursor out-of-the-box afaik.. will clean that up soon.

@lukasmasuch Just read this twitter.com/tibor_tee/arti…)%20Avoid%20duplicating,place%20propagate%20everywhere. This should remove some of the duplicated folders you have with Claude and Cursor, right?

@anders_boje We tried to push all relevant configurations into the repo to have it work just fine out of the box for Cursor and Claude Code. This includes some vscode, cursor, and claude settings. For cursor we have this minimal instruction here: #vs-code--cursor-setup" target="_blank" rel="nofollow noopener">github.com/streamlit/stre…

@lukasmasuch Thanks for a detailed and valuable blog post. One question: do you have or need a separate guide on how to set up Cursor or Claude Code to get the most out of the developer experience? In Cursor, it could be things like downloading this MCP, toggling on this feature, etc.

@domjost Previously, we did all our spec collaboration on Notion. But we moved this to Github PRs using comments and approval, e.g.: github.com/streamlit/stre… Not perfect, but works good enough for us.

@lukasmasuch Inspiring @lukasmasuch! I'd love to learn more about "Move context into the repo": - Why are architecture doc (skill) and API design principles (AGENTS.md) not part of the wiki? - How do you keep specs and implementation in sync? - How do you collaborate on spec writing?

@domjost Our (product) specs are often created together with prototypes which helps to go from spec to merge-ready implementation in most cases without additional iterations on the spec. But if it needs tweaks, we just merge int the changes together with the feature PR.

@domjost The architecture and principles are human-reviewed and more permanent. We want agents to take those seriously. Documents in the agent wiki have a more temporary value and no guarantees to be correct. The AGENTS.md within the agent wiki points this out: raw.githubusercontent.com/wiki/streamlit…

stlite@0.48.0 is finally out shipping Streamlit@1.32.2! Init loading time became ~2.5x faster ⚡️ github.com/whitphx/stlite… #Streamlit #Wasm #Pyodide

We released a new version of stlite, Serverless #Streamlit, 0.43.1, whose backend Streamlit has been upgraded to 1.27.0, with a huge contribution by @lukasmasuch from @Streamlit! You can finally use the new features such as st.satter_chart on stlite too! edit.share.stlite.net

NEWS: Lucid CEO Peter Rawlinson tops the charts as the highest-paid automotive CEO in 2022: $379 million driveteslacanada.ca/news/lucid-ceo…

stlite, Serverless Streamlit now supports st_data_editor() and other Arrow-based new features. This has been realized with huge support by @lukasmasuch from @Streamlit ! Try it out -> edit.share.stlite.net

Carve out a few hours to learn streamlit.io Powerful for rapid prototyping, interactive visualization. It's a hammer and you'll start seeing a lot of nails.

@JoHeidecke Congrats, Johannes🎉 GPT4 is incredible and indeed very well-behaved!

What an incredibly exhilarating journey it has been, working along so many great people on making #GPT4 our safest and most well-behaved model so far. There is still loads of work to do, but taking a moment to celebrate!

So many use-cases for @streamlit's new data editor command! A couple of them at data-editor.streamlit.app - curious to see how the community will use it! 👏 @lukasmasuch @jrieke

🚨 Release 1.19.0 🚀 Editable dataframes are live! With st.experimental_data_editor you can now interact with the dataframes in your apps. Upgrade to try it out. 🤩 📝 Release notes: discuss.streamlit.io/t/version-1-19… 📑Docs: docs.streamlit.io/library/api-re… #python #dataframes #ui

@ben_j_lindsay Happy to build this and thanks for proposing the interface. Sometimes all it needs is a new interface on existing code 😊 Maybe its useful for other @streamlit users as well

@ThiagoTDotCom @ben_j_lindsay @streamlit Released an update today 🎉 Should be ready for beta usage :) Now it also provides the proposed pydantic_form method and a playground: share.streamlit.io/lukasmasuch/st…

@ThiagoTDotCom @ben_j_lindsay @streamlit Sorry for messing with your weekend :) Luckily, I already finished extracting and updating the relevant code... so it's super easy to play around: github.com/LukasMasuch/st…

@ben_j_lindsay @ThiagoTDotCom @streamlit I'm happy to unify the efforts. This is currently just an alpha version, and I haven't decided If I actually want to maintain this :)

@ben_j_lindsay @ThiagoTDotCom @streamlit The code from opyrator might already have most things that are possible right now with pydantic->streamlit combo, and also requires some not-super-nice tricks. I have extracted and update the relevant parts here (was actually less work than expected): github.com/lukasmasuch/st…
