Fixes#9313
[Screencast from 2024-03-22 09-09-07.webm](https://github.com/enso-org/enso/assets/3919101/6ad86145-6882-4bde-993d-b1270f1ec06c)
# Important Notes
* This is PoC, so I didn't spend time on polishing the visuals; the design will likely change.
* I modified the shortcut handler a bit, allowing making multiple actions for same binding - the action's handler will be called in unspecified order, until one of them handle the event (i.e. not return false).
* To make it working regardless of imports, I needed to export AI module in Standard.Visualization. Moreover, needed to remove build_ai_prompt for Any, because it was causing issues - expect a bug report soon.
This is a set of split off changes made as a side effect while working on engine reconnection handling.
Cleaned up GUI e2e setup, unified as much of the entrypoint code as possible. Currently the only real difference between the real and testing entrypoint is mocking of all network calls and not loading through dashboard.
I've managed to completely get rid of `MockApp`, and remove tricky mocking of pinia stores.
- Fixes support for vibrancy
- Disable background when vibrancy is enabled
- Minor refactors to pass the relevant config option to dashboard, so that the dashboard knows whether vibrancy is enabled
- Enable vibrancy on Linux if a special environment variable is set
# Important Notes
- MUST be tested on macOS
- Windows *does not support resizing* when vibrancy is enabled. This is a limitation of Windows - see [this issue](https://github.com/electron/electron/issues/6107).
- Fix the UI problems with our CodeMirror integration (Fixed view stability; Fixed a focus bug; Fixed errors caused by diagnostics range exceptions; Fixed linter invalidation--see https://discuss.codemirror.net/t/problem-trying-to-force-linting/5823; Implemented edit-coalescing for performance).
- Introduce an algorithm for applying text edits to an AST. Compared to the GUI1 approach, the new algorithm supports deeper identity-stability for expressions (which is important for subexpression metadata and Y.Js sync), as well as reordered-subtree identification.
- Enable the code editor.
- 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.
Some refactoring separated from #8825 for easier review.
# Important Notes
**ID types**
The new *synchronization IDs* will replace `ExprId` for `Ast` references in frontend logic. `ExprId` (now called `ExternalId`) is now used only for module serialization and engine communication. The graph database will maintain an index that is used to translate at the boundaries. For now, this translation is implemented as a type cast, as the IDs have the same values until the next PR.
- `AstId`: Identifies an `Ast` node.
- `NodeId`: A subtype of `AstId`.
- `ExternalId`: UUID used for serialization and engine communication.
**Other changes**:
- Immediate validation of `Owned` usage.
- Eliminate `Ast.RawCode`.
- Prepare to remove `IdMap` from yjsModel.
- Closes https://github.com/enso-org/cloud-v2/issues/804
- The GUI should now properly configure deep links and auth settings, among other things, because the logic has been ported over from the GUI1 runner.
- The porting was very basic; it may be a good idea to refactor it later, but that is out of scope of this PR.
- This also means that `runner/` should be safe to remove along with GUI1 in the future, as all code relevant to GUI2 now resides in `app/gui2/runner`.
# Important Notes
- The built `ide2` has been tested on Windows, but should also be tested on macOS.
- Should *also* be fully tested in `npm run dev`.
- 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.
- Closes#8072
- Implement handlers for the corresponding buttons on the circular menu
- Add missing icons and styles
- Add functionality to match and extract ASTs
# Important Notes
None
