# Changelog
|
|
|
|
All notable changes to Ebox are documented here.
|
|
|
|
## 2.0.0 (Unreleased)
|
|
|
|
### Added
|
|
|
|
- Direct dependencies on the independent ECSS 0.1.0 cascade engine and TP 1.0.0 retained/reactive text runtime.
|
|
- ECSS-backed property schemas, selectors, stylesheets, inheritance, cascade layers, custom properties, computed values, and provenance for Box, Flex, and Grid nodes.
|
|
- Surface-scoped region handles through `ebox-region-resolve`, retained TP publication through `ebox-render-to-buffer` and `ebox-display-buffer`, and atomic handle/selector/viewport/scroll updates.
|
|
- Typography longhands and inherited foreground projection that keep text readable when child boxes override background colors.
|
|
|
|
### Changed
|
|
|
|
- ECSS is the only selector matcher and cascade winner. Ebox adapts node trees to ECSS subjects, interprets computed values for measurement/layout/paint, and classifies their layout impact.
|
|
- TP is the only live buffer writer. Ebox produces retained surface candidates and semantic dirty-owner plans; TP owns diff execution, marker-backed mounts, revisions, transactions, and rollback.
|
|
- Flex and Grid container/item declarations enter the same ECSS pipeline as ordinary boxes instead of maintaining a parallel style path.
|
|
- Region updates use opaque surface-scoped handles. The same declarative source may be mounted in multiple buffers without sharing live identity.
|
|
|
|
### Removed
|
|
|
|
- `ebox-pop-to-buffer`, `ebox-switch-to-buffer`, and the private erase-and-evaluate buffer writer they exposed.
|
|
- Ebox's duplicate selector parser/matcher and duplicate cascade winner.
|
|
- Bundled playground fixtures. Executable `.ebox` references live in the independent `ebox-playground` package.
|
|
|
|
### Migration
|
|
|
|
- Install ECSS 0.1.0 and TP 1.0.0, in either order, before Ebox 2.0.0.
|
|
- Replace numeric region-id mutation with `ebox-region-resolve` followed by `ebox-region-update` on the returned handle.
|
|
- Replace `ebox-pop-to-buffer` or `ebox-switch-to-buffer` with `ebox-display-buffer`, or call `ebox-render-to-buffer` when display is controlled by the caller.
|
|
- Ebox does not scan previously rendered text to reconstruct runtime identity. Remount the declarative source through Ebox 2.0.
