Crate ochrepad_core 

Headless editing core: text, positions, selections, actions, transactions and undo. No egui and no filesystem access (PLAN 3.1, 7).

Modules

action

Action: what the user intends, independent of where the carets are (PLAN 3.5). Key bindings map to actions and macros record them.

buffer

Buffer: one document’s text, undo history, revisions and file metadata.

changeset

ChangeSet: concrete, non-overlapping edits against one document state.

diff

Line and word diff for the compare view (PLAN M12), using similar.

display

Display rows: how a view’s document lines map to rows on screen (PLAN_v0.2.0 3.2). A row is addressed relative to its line, as a RowPos, so nothing needs a global row index: with word wrap that would mean wrapping the whole file. Lines hidden by a fold have no rows; with word wrap on, a line has one row per wrapped piece, otherwise one.

editor

Editor: owns buffers and views. Editor::apply is the only path that mutates a document (PLAN 3.5).

fold

Code folding (PLAN_v0.2.0 N3): where regions are, and which are folded in a view.

history

Undo/redo over Transactions, with coalescing of consecutive typing.

macros

Macro playback. Recording happens in Editor::apply: while recording, every successful recordable action is appended.

position

Position newtypes and the conversions between them.

search

Find and replace over the document without copying it into a String.

selection

Selections are always a set (PLAN 3.3). A plain cursor is a set of one empty selection.

text

Document: the rope, addressed only by ByteOffset.

transform

Text transforms: case conversion, line sorting, and line operations (trim, duplicate, move, join, remove empty or duplicate lines). Each resolves to one transaction.

view

View: a window onto a buffer with its own selections and scroll position.
