Problem

As evidenced in #5273, Jupyter Notebook users would love to edit notebooks. There's a need for seamless integration that supports the variety of media types in Jupyter notebooks and the interactive runtimes underneath.

Proposed Plan

The fastest path where we'll see progress along the way will be to:

• Create a kernel/runtime manager for Zed ✅
• Enable execution in the editor, a la Hydrogen ✅
• Create a notebook viewer ✅
• Allow execution in notebooks ✅

In parallel, we can work on new GPUI features to support rendering custom media types that Jupyter users expect.

Steps

Runtime support

To bring Jupyter kernels (aka runtimes aka REPLs) to Rust, the https://github.com/runtimed/runtimed project has been started.

• Discover python and/or jupyter kernel environments
• Launch kernels/runtimes
• Track kernels/runtimes in their own pane

Notebook File support

• New filetype support (Foundations for Open All the Things #9353, Image viewer #9425)
• Load Jupyter notebooks .ipynb into a new viewer
• Full Buffer integration inside Jupyter Notebooks (LSPs, vim, etc.)
• Ability to focus from one cell to another
• Move cells around
• Vim Mode inside Jupyter View

Rich Media -> GPUI needs

Some of the needs for notebook and/or in-editor execution will require GPUI work. Some will be able to reuse existing components as is (div, img, markdown preview).

These are the likely mediatypes to support:

• text/plain -> div()
• image/svg+xml, image/png, image/jpeg, image/gif
• application/vnd.dataresource+json - built in table support
• text/markdown - repl: Streamline Markdown output usage #47713
• text/html - repl: Use wry to render HTML outputs #48157
• text/latex - repl: Add LaTeX mimetype support #44525, Add LaTeX rendering to Markdown preview #48143
• application/json - repl: Render application/json media types from Jupyter kernels #47905
• application/geo+json - requires repl: Use wry to render HTML outputs #48157
• VegaLite, Vega - requires repl: Use wry to render HTML outputs #48157
• application/javascript - requires repl: Use wry to render HTML outputs #48157
• application/vnd.jupyter.widget-view+json, application/vnd.jupyter.widget-state+json - no support

Kernel Improvements

• REPL support inside dev containers
• Recommendation based on worktree/project
• Easy control and UI/UX for managing current Kernels
• Union and predictable behavior over all modes of repl ( remote/local )
