Implementation notes:
|
- The module is edited by changing the AST, not the text representation. - `IdMap`s no longer need to be maintained in parallel with the module content; they are snapshots produced as needed from the ASTs. - Simplistic synchronization is in place until #8237: Edits are never merged; if two edits are started from the same state, one will be overwritten.

) - Synchronize Y.Js clients by AST (implements #8237). - Before committing an edit, insert any parentheses-nodes needed for the concrete syntax to reflect tree structure (fixes #8884). - Move `externalId` and all node metadata into a Y.Map owned by each `Ast`. This allows including metadata changes in an edit, enables Y.Js merging of changes to different metadata fields, and will enable the use of Y.Js objects in metadata. (Implements #8804.) ### Important Notes - Metadata is now set and retrieved through accessors on the `Ast` objects. - Since some metadata edits need to take effect in real time (e.g. node dragging), new lower-overhead APIs (`commitDirect`, `skipTreeRepair`) are provided for careful use in certain cases. - The client is now bundled as ESM. - The build script cleans up git-untracked generated files in an outdated location, which fixes lint errors related to `src/generated` that may occur when switching branches.
To be done after #8367
Use new AST implemented in #8236 as the representation synchronized through Yjs.
