Still TODO:
|
|
- Wire up Nodebuilder to track listeners as they are added. (easyish)
|
|
- Wire up attrs on nodes to track listeners properly
|
|
- Could be done in the nodebuilder where the attrs are added automatically (easyish)
|
|
- Could just inject context into the diffing algorithm (hardish)
|
|
- Wire up component syntax (easy)
|
|
- Wire up component calling approach (easyish)
|
|
- Wire up component diffing (hardish)
|
|
|
|
|
|
Approach:
|
|
- move listeners out of vnode diffing
|
|
- move listeners onto scope via nodebuilder
|
|
- instead of a listeners list, store a list of listeners and their IDs
|
|
- this way means the diffing algorithm doesn't need to know that context
|
|
- This should fix our listener approach
|
|
- The only thing from here is child component
|
|
|
|
|
|
Thoughts:
|
|
- the macros should generate a static set of attrs into a [attr] array (faster, more predictable, no allocs)
|
|
- children should be generated as a static set if no parans are detected
|
|
- More complex in the macro sized, unfortunately, not *too* hard
|
|
- Listeners should also be a static set (dynamic listeners don't make too much sense)
|
|
- use the builder syntax if you're doing something wild and need this granular control
|
|
- Tags should also be &'static str - no reason to generate them on the fly
|
|
|
|
Major milestones going forward:
|
|
- Scheduled updates
|
|
- String renderer (and methods for accessing vdom directly as a tree of nodes)
|
|
- good existing work on this in some places
|
|
- Suspense
|
|
- Child support, nested diffing
|
|
- State management
|
|
- Tests tests tests
|
|
|
|
Done so far:
|
|
- websys
|
|
- webview
|
|
- rsx! macro
|
|
- html! macro
|
|
- lifecycles
|
|
- scopes
|
|
- hooks
|
|
- context API
|
|
- bump

## Solutions from today's thinking session...
|
|
|
|
### To solve children:
|
|
|
|
- maintain a map of `ScopeIdx` to `Node` in the renderer
|
|
- Add new patch commands
|
|
- traverse_to_known (idx)
|
|
- Pop known component onto stack (super easy)
|
|
- add_known (idx)
|
|
- Save top of stack as root associated with idx
|
|
- remove_known (idx)
|
|
- Remove node on top of stack from known roots
|
|
- ... Something like this
|
|
- Continue with BFS exploration of child components, DFS of VNodes
|
|
- Easier to write, easier to reason about
|
|
|
|
### To solve listeners:
|
|
|
|
- Map listeners directly as attrs before diffing via a listenerhandle
|
|
- Evaluation of nodes is now stateful where we track listeners as they are added
