There's still a bit more work to do on this, but this PR is compiling
(with warnings) after eliminating the key types. When the tasks below
are complete, this will be the new narrative for GPUI:
- `Entity<T>` - This replaces `View<T>`/`Model<T>`. It represents a unit
of state, and if `T` implements `Render`, then `Entity<T>` implements
`Element`.
- `&mut App` This replaces `AppContext` and represents the app.
- `&mut Context<T>` This replaces `ModelContext` and derefs to `App`. It
is provided by the framework when updating an entity.
- `&mut Window` Broken out of `&mut WindowContext` which no longer
exists. Every method that once took `&mut WindowContext` now takes `&mut
Window, &mut App` and every method that took `&mut ViewContext<T>` now
takes `&mut Window, &mut Context<T>`
Not pictured here are the two other failed attempts. It's been quite a
month!
Tasks:
- [x] Remove `View`, `ViewContext`, `WindowContext` and thread through
`Window`
- [x] [@cole-miller @mikayla-maki] Redraw window when entities change
- [x] [@cole-miller @mikayla-maki] Get examples and Zed running
- [x] [@cole-miller @mikayla-maki] Fix Zed rendering
- [x] [@mikayla-maki] Fix todo! macros and comments
- [x] Fix a bug where the editor would not be redrawn because of view
caching
- [x] remove publicness window.notify() and replace with
`AppContext::notify`
- [x] remove `observe_new_window_models`, replace with
`observe_new_models` with an optional window
- [x] Fix a bug where the project panel would not be redrawn because of
the wrong refresh() call being used
- [x] Fix the tests
- [x] Fix warnings by eliminating `Window` params or using `_`
- [x] Fix conflicts
- [x] Simplify generic code where possible
- [x] Rename types
- [ ] Update docs
### issues post merge
- [x] Issues switching between normal and insert mode
- [x] Assistant re-rendering failure
- [x] Vim test failures
- [x] Mac build issue
Release Notes:
- N/A

When the user closes a tab, the tab switcher will now select the tab at
the same position. This feature is especially relevant for keyboard
users when you want to close multiple consecutive tabs with
`<Ctrl-Backspace>`.
Please see the discussion at
https://github.com/zed-industries/zed/discussions/22791 for full
motivation and the quick demo.
Release Notes:
- tab_switcher: Preserve selected position when tab is closed
The Tab Switcher implementation (#7653):
- `ctrl-tab` opens the Tab Switcher and moves selection to the
previously selcted tab. It also cycles selection forward.
- `ctrl-shift-tab` opens the Tab Switcher and moves selection to the
last tab in the list. It also cycles selection backward.
- Tab is selected and the Tab Switcher is closed on the shortcut
modifier key (`ctrl` by default) release.
- List items are in reverse activation history order.
- The list reacts to the item changes in background (new tab, tab
closed, tab title changed etc.)
Intentionally not in scope of this PR:
- File icons
- Close buttons
I will come back to these features. I think they need to be implemented
in separate PRs, and be synchronized with changes in how tabs are
rendered, to reuse the code as it's done in the current implementation.
The Tab Switcher looks usable even without them.
Known Issues:
Tab Switcher doesn't react to mouse click on a list item. It's not a tab
switcher specific problem, it looks like ctrl-clicks are not handled the
same way in Zed as cmd-clicks. For instance, menu items can be activated
with cmd-click, but don't react to ctrl-click. Since the Tab Switcher's
default keybinding is `ctrl-tab`, the user can only click an item with
`ctrl` pushed down, thus preventing `on_click()` from firing.
fixes#7653, #7321
Release Notes:
- Added Tab Switcher which is accessible via `ctrl-tab` and
`ctrl-shift-tab` (#7653) (#7321)
Related issues:
- Unblocks #7356, I hope 😄
How it looks and works (it's only `ctrl-tab`'s and `ctrl-shift-tab`'s,
no `enter`'s or mouse clicks):
