@searsuite/sear-domain-editor

Creates an indexed snapshot from ordered items and selector functions.

Returns one item by its numeric index.

Returns one item by its stable key.

Returns keys for the supplied numeric indexes, preserving input order.

Creates a layout cache from already computed block records.

Returns the cached layout record for a document block id.

Returns the cached layout record for a top-level block index.

Returns block ids for the supplied top-level block indexes.

Returns all cached block records intersecting the supplied vertical range.

Returns block indexes whose internal content layout can be reused from a previous cache.

A downstream flow shift changes absolute rect.y, so the whole block record cannot be reused. The renderer can still reuse the block's measured content shape when line count, visual size and flow height are unchanged.

Returns whether one block's height-sensitive flow layout changed.

Returns whether one block's flow height changed compared with another cache.

Builds a block layout cache from a rich document and its layout snapshot.

DI token for resolving DocLayoutEngine.

Build a LayoutSnapshot from the current blockManager state.

Prerequisites: callers must add all document paragraphs to blockManager before building the snapshot.

Builds a snapshot for selected top-level document blocks.

The returned lines keep their full-document text paths, but only the requested blocks are materialized. Callers supply each block's document Y-position from a block-height index.

Convert a DocCursorPos to pixel coordinates relative to the editor box top-left corner.

Returns the position of the cursor bar's horizontal anchor (i.e. the x at which to draw the vertical cursor line, and the y passed to drawCursor), plus the line height needed to size the cursor bar.

Returns the index into snapshot.lines for the line containing pos. Returns 0 if not found.

Compute canvas-space rectangles for a non-collapsed DocSelection.

ReturnsArray of {x,y,width,height} rectangles in canvas coordinates.

Convert a pixel position (relative to the editor box top-left) to the nearest DocCursorPos.

Used for click-to-position-cursor and drag-selection.

Creates a page map from immutable page records.

Gap between pages in document coordinates.

Page height used by this map.

Ordered page layout records.

Returns a page record by index.

Returns page indexes that intersect a block id.

Returns pages for the supplied page indexes, preserving page order.

Returns all pages intersecting a block layout record.

Returns all pages intersecting the supplied vertical document range.

Builds a page map by intersecting cached block rectangles with fixed-height pages.

Creates a viewport window from document-space rectangle coordinates.

Visible height in document units.

Visible width in document units.

Left edge in document coordinates.

Top edge in document coordinates.

Returns whether this viewport intersects another document-space rectangle.

Creates a document-space window from a viewport rectangle and scroll offsets.

Items in their canonical order.

Returns one item by its numeric index.

Returns one item by its stable key.

Returns keys for the supplied numeric indexes, preserving input order.

Constructs the editor service.

DI token for resolving the editor service.

Initializes document-editor runtime state.

Block records for the materialized blocks, using full-document indexes.

Line snapshot containing only the materialized block ranges.

Flow height from this block top to the next block top, or visual height for the last block.

Stable block identity used by retained render nodes.

Zero-based top-level document block index.

Exclusive index after the last layout line belonging to this block.

Inclusive index of the first layout line belonging to this block.

Document-space rectangle occupied by this block.

Reflow blocks whose render output changed even if their measured layout shape did not.

Repaint blocks whose render output changed without invalidating layout cache.

Height in document units.

Width in document units.

Left edge in document coordinates.

Top edge in document coordinates.

Block ids that intersect this page.

Zero-based page index.

Page rectangle in document coordinates.

Last top-level document block index included in the buffered viewport.

Last page index included in the buffered viewport.

First top-level document block index included in the buffered viewport.

First page index included in the buffered viewport.

Returns the viewport width/height.

Returns the current scroll offset in document coordinates.

Per-character measurements for this line.

Char offset (within the text node) of the FIRST character on this line. e.g. if a text node wraps at char 20, the second line has charStartOffset=20.

Cursor boundary x offsets relative to this line's x, one entry per char boundary.

Font ascent: distance from baseline to top of tallest glyph on this line.

Line height in CSS/canvas pixels.

Full path to the text node this line belongs to.

For a flat document (paragraph → single text node): textNodePath = [paraIndex, 0]

The path mirrors DocCursorPos.path semantics: a cursor at { path: textNodePath, offset } lives on this line when charStartOffset <= offset <= charStartOffset + chars.length.

Left edge of text, relative to editor box top-left (includes cellPadding).

Y coordinate used for fillText/cursor drawing, relative to editor box top-left. This is the baseline consumed by document render nodes so cursor pixel coordinates align with rendered text.
