Primitives

The foundational types Helix is built from. These appear in nearly every file in the codebase, and learning them well pays off when reading any subsystem.

Pages

• Rope — the persistent text buffer.
• Selection — Range and Selection, the editing target.
• Transaction — ChangeSet, Operation, and reversible edits.
• Document — open file: rope + selections + syntax + history.
• View — viewport into a Document with scroll, gutter, and a jumplist.

For a hands-on tour of how these compose, see overview/architecture.
