magit-section

What problem does it solve?

magit-section provides a robust framework for building tree-like, collapsible buffers with sections that can contain nested content, navigation, and per-section behavior—ideal for complex interfaces like Magit's.

Core Features & Use Cases

• Hierarchical Sections: Create nested sections with headings and bodies.
• Visibility & Caching: Collapse/expand sections with caching of visibility state.
• Navigation & Actions: Built-in movement and per-section keymaps for custom actions.
• Data Association: Attach arbitrary values to sections for rich interactivity.
• Use Cases: File browsers, log viewers, configuration inspectors, and custom UIs.

Quick Start

To begin:

• Require the library: (require 'magit-section)
• Create a root section and nested sections:

  (magit-insert-section (root)
    (magit-insert-heading "Root")
    (magit-insert-section (child "child-1")
      (magit-insert-heading "Child 1")
      (insert "Content here")))
  

• Navigate with TAB to toggle visibility or use movement commands like magit-section-forward/ backward.
