on GitHub

This release improves marimo's code intelligence with runtime completions, expands notebook conversion capabilities, and includes several UI/UX improvements and bug fixes.

✨ Highlights

Dynamic key completion

marimo now offers runtime key completions for dictionaries, dataframes, and other subscriptable objects (#5618). Unlike static LSP completions, these suggestions come from inspecting objects in memory, enabling completions that are only knowable at runtime.

When you type dataframe[", marimo suggests column names. When accessing dictionary keys, you'll see all available keys as completions. This works with:

• Dictionary keys - my_dict[" shows all available keys
• DataFrame columns - df[" suggests column names
• Custom objects - Any object implementing _ipython_key_completions_()

py:percent support in marimo convert

marimo convert now supports converting py:percent format (#5686). Convert your py:percent notebooks directly to marimo notebooks:

# Requires jupytext
uvx --with=jupytext marimo convert pypercent_notebook.py -o notebook.py

The converter also works for ingesting regular Python scripts. If you try to open a non-marimo Python script with marimo edit, you'll now be prompted to convert it first.

Column layout improvements

Keyboard navigation is now supported with column layouts! You can move between columns using the arrow keys in command mode (or h/l for Vim users) (#5760). We've also redesigned the column layout UI (#5772).

Console output text wrapping

Long console outputs are now easier to read with the new text wrapping toggle (#5739). A button appears on hover in the top-right corner of console outputs, letting you toggle between wrapped and unwrapped text.

🚨 Breaking changes

• Vim keybindings now require Ctrl+Escape (or Cmd+Escape on macOS) to enter command mode (#5815, #5837).

  Previously, pressing Escape from Vim normal mode would enter Command Mode, but this caused confusing behavior and accidental mode switches for Vim users. Adding this extra modifier prevents unintended exits from normal mode while letting you choose whether to use Command Mode at all.
