MingaEditor.State.Registers (Minga v0.1.0)

Copy Markdown View Source

Groups register-related fields from EditorState.

Tracks the named register store and the currently selected register (set by "x before an operator).

Each register entry is a {text, type} tuple where type is :charwise or :linewise. Linewise entries (from yy, dd, visual-line yank) paste as new lines; charwise entries paste inline at the cursor.
