0.8.0

• feat: Add --node-caret-boundary CSS token that lets consumers clamp edge gaps (before first / after last node) to a parent element's border box, preventing overlap with neighboring UI elements
• fix: When selection has no common parent, return null
• fix: document --row for node arrays in README
• fix: Move NodeGap from being a child of Node to a sibling rendered by NodeArrayProperty. The reason is that Node gaps are getting zero width when a node has transform, filter, or will-change (which create new containing blocks that break CSS anchor positioning for child elements).

Full Changelog: v0.6.4...v0.7.0

Migration guide

Gap and selection rendering moved from user-land into the library with sensible defaults. Orientation detection replaced JS getComputedStyle reads with pure CSS (--row: 1/0). Gaps fill the space between nodes in a NodeArray (min 16px if no gap/padding), and hit targets fill available space for better ergonomics (Fitts's law). Components renamed for clarity.

Breaking changes

1. system_components: NodeCursorTrap no longer required

Before: NodeCursorTrap had to be imported from user-land and passed in system_components:

import NodeCursorTrap from './components/NodeCursorTrap.svelte';
import Overlays from './components/Overlays.svelte';

system_components: {
  NodeCursorTrap,
  Overlays
}

After: Gap components ship as library defaults. Only pass your own overlays:

import Overlays from './components/Overlays.svelte';

system_components: {
  Overlays  // optional: link previews, image editors, etc.
}

Overridable defaults (all optional): NodeGap, NodeGapMarkers, NodeSelectionMarkers.

2. Component and CSS renames

Before (main)	After
NodeCursorTrap component	NodeGap (library export)
.cursor-trap class	.node-gap
data-type="after-node-cursor-trap"	data-type="gap-after"
data-type="position-zero-cursor-trap"	data-type="gap-before"

Update any custom CSS or JS queries targeting these.

3. --layout-orientation replaced by --row

Before: Orientation was a CSS string read via JS at runtime:

--layout-orientation: horizontal; /* or vertical */

After: Pure CSS numeric toggle, no JS needed:

--row: 1; /* horizontal (default — matches flex-direction: row) */
--row: 0; /* vertical */

Default is 1 (horizontal). Vertical containers must set --row: 0 explicitly:

.my-vertical-container {
  flex-direction: column;
  --row: 0;
}

4. Overlays is now user-land only

Before Overlays contained both node selection overlays and custom UI (link actions). Selection rendering now lives in NodeSelectionMarkers (rendered automatically by Svedit). Overlays is only for your own UI.

5. CSS variables to customize editor colors have changed

Override Svedit's default colors with:

--svedit-brand: oklch(60% 0.22 100);
--svedit-editing-stroke: var(--svedit-brand);
--svedit-editing-fill: oklch(from var(--svedit-brand) l c h / 0.1);
--svedit-canvas-stroke: color-mix(in oklch, currentColor 25%, transparent);

0.6.1

• fix: Ensure selection direction is preserved in when rendering text selections
