This guide introduces some of these features.

Settings

Overview panels

marimo ships with the following IDE-like panels that help provide an overview of your notebook:

  1. errors: view errors in each cell;

  2. variables: explore variable values, see where they are defined and used, with go-to-definition;

  3. dependency graph: view dependencies between cells, drill-down on nodes and edges;

  4. table of contents: corresponding to your markdown;

  5. logs: a continuous stream of stdout and stderr.

  6. snippets - searchable snippets to copy directly into your notebook

  7. documentation - move your text cursor over a symbol to see its documentation

Click these buttons to access the editor panels.

These panels can be toggled via the buttons in the lower left of the editor.
