Closes#10454
Implements SVG file preview capability similar to the existing markdown
preview.
- Adds `svg_preview` crate with preview view and live reloading upon
file save.
- Integrates SVG preview button in quick action bar.
- File preview shortcuts (`ctrl/cmd+k v` and `ctrl/cmd+shift+v`) are
extension-aware.
Release Notes:
- Added SVG file preview, accessible via the quick action bar button or
keyboard shortcuts (`ctrl/cmd+k v` and `ctrl/cmd+shift+v`) when editing
SVG files.
This PR fixes several possible memory leaks due to loading images in
markdown files and the image viewer, using the new image cache APIs
TODO:
- [x] Ensure this didn't break rendering in any of the affected
components.
Release Notes:
- Fixed several image related memory leaks
resolves#24655resolves#23945
I haven't yet added a default binding for the new command. #27797 added `:ls` and
`:buffers` which in my opinion should use the global searchable version
given that that matches the vim semantics of those commands better than
just showing the tabs in the local pane.
There's also a question of what to do when you select a tab from another
pane, should the focus jump to that pane or should that tab move to the
currently focused pane? For now I've implemented the former.
Release Notes:
- Added `tab_switcher::ToggleAll` to search open tabs from all panes and focus the selected one.

Note:
This is implemented in a very hacky and one-off manner. The primary
change is to pass a rem size through the markdown render tree, and scale
all sizing (rems & pixels) based on the passed in rem size manually.
This required copying in the `CheckBox` component from `ui::CheckBox` to
make it use the manual rem scaling without modifying the `CheckBox`
implementation directly as it is used elsewhere.
A better solution is required, likely involving `window.with_rem_size`
and/or _actual_ `em` units that allow text-size-relative scaling.
Release Notes:
- Made it so Markdown preview uses the _buffer_ font size instead of the
_ui_ font size.

TODO:
- [x] Use AsyncFn instead of Fn() -> Future in GPUI spawn methods
- [x] Implement it in the whole app
- [x] Implement it in the debugger
- [x] Glance at the RPC crate, and see if those box future methods can
be switched over. Answer: It can't directly, as you can't make an
AsyncFn* into a trait object. There's ways around that, but they're all
more complex than just keeping the code as is.
- [ ] Fix platform specific code

Closes#25384
Markdown preview now subscribes to `ExcerptsEdited` event which is
emited when edit prediction is accepted.
Release Notes:
- Fixed markdown preview not updating when edit prediction is accepted.
Done automatically with
> ast-grep -p '$A.background_executor().spawn($B)' -r
'$A.background_spawn($B)' --update-all --globs "\!crates/gpui"
Followed by:
* `cargo fmt`
* Unexpected need to remove some trailing whitespace.
* Manually adding imports of `gpui::{AppContext as _}` which provides
`background_spawn`
* Added `AppContext as _` to existing use of `AppContext`
Release Notes:
- N/A
I believe this takes care of the remaining events running through the
old flow that requires transformation at the collab server level. I
think all events are now going through `telemetry::event!()`.
For anyone curious where the new telemetry names are coming from, you
can check the `for_snowflake` function within
`crates/collab/src/api/events.rs`, to see how collab is currently
transforming the events going through the old flow.
Release Notes:

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

Closes#21534
While investigating the panic, I noticed that the code was pretty
complicated and decided to refactor parts of it to reduce redundancy.
Release Notes:
- Fixed an issue where the app could crash when opening the markdown
preview with a malformed image tag
This is a behavior-preserving change, but lays the groundwork for
expanding selections when the cursor lands inside of a "replace" block.
Release Notes:
- N/A
Also change Zed's standard style to use
`.track_focus(&self.focus_handle(cx))`, instead of
`.track_focus(&self.focus_handle)`, to catch these kinds of errors more
easily in the future.

This PR adds a streamlined way to consistently construct tab content for
items that only have textual content in the tabs.
The `Item` trait now has a new `tab_content_text` method that can be
used to return the textual content for the tab.
The `tab_content` method now has a default implementation that—unless
overridden—will construct a `Label` out of the text. This default
implementation also takes care of setting the label color based on the
active state of the tab, something that previously had to be repeated in
each `tab_content` implementation.
The majority of our tabs are now using `tab_content_text`.
Release Notes:
- N/A
This PR reworks the rendering for tab icons to allow us to render all of
the tab icons—not just file icons—in the tab's start slot.
The `Item` trait now has a separate `tab_icon` method that can be used
to indicate what icon should be shown for the tab.
Release Notes:
- N/A
Fixes a panic related to rendering checkboxes, see #10824.
Currently we are rendering a list into a single block, meaning the whole
block has to be rendered when it is visible on screen. This would lead
to performance problems when a single list block contained a lot of
items (especially if it contained checkboxes). This PR splits up list
items into separate blocks, meaning only the actual visible list items
on screen get rendered, instead of the whole list.
A nice side effect of the refactoring is, that you can actually click on
individual list items now:

Release Notes:
- Improved rendering performance of list elements inside the markdown
preview

This PR implements the preview tabs feature from VSCode.
More details and thanks for the head start of the implementation here
#6782.
Here is what I have observed from using the vscode implementation ([x]
-> already implemented):
- [x] Single click on project file opens tab as preview
- [x] Double click on item in project panel opens tab as permanent
- [x] Double click on the tab makes it permanent
- [x] Navigating away from the tab makes the tab permanent and the new
tab is shown as preview (e.g. GoToReference)
- [x] Existing preview tab is reused when opening a new tab
- [x] Dragging tab to the same/another panel makes the tab permanent
- [x] Opening a tab from the file finder makes the tab permanent
- [x] Editing a preview tab will make the tab permanent
- [x] Using the space key in the project panel opens the tab as preview
- [x] Handle navigation history correctly (restore a preview tab as
preview as well)
- [x] Restore preview tabs after restarting
- [x] Support opening files from file finder in preview mode (vscode:
"Enable Preview From Quick Open")
I need to do some more testing of the vscode implementation, there might
be other behaviors/workflows which im not aware of that open an item as
preview/make them permanent.
Showcase:
https://github.com/zed-industries/zed/assets/53836821/9be16515-c740-4905-bea1-88871112ef86
TODOs
- [x] Provide `enable_preview_tabs` setting
- [x] Write some tests
- [x] How should we handle this in collaboration mode (have not tested
the behavior so far)
- [x] Keyboard driven usage (probably need workspace commands)
- [x] Register `TogglePreviewTab` only when setting enabled?
- [x] Render preview tabs in tab switcher as italic
- [x] Render preview tabs in image viewer as italic
- [x] Should this be enabled by default (it is the default behavior in
VSCode)?
- [x] Docs
Future improvements (out of scope for now):
- Support preview mode for find all references and possibly other
multibuffers (VSCode: "Enable Preview From Code Navigation")
Release Notes:
- Added preview tabs
([#4922](https://github.com/zed-industries/zed/issues/4922)).

This PR contains various improvements for the markdown preview (some of
which were originally part of #7601).
Some improvements can be seen in the video (see also release notes down
below):
https://github.com/zed-industries/zed/assets/53836821/93324ee8-d366-464a-9728-981eddbfdaf7
Release Notes:
- Added action to open markdown preview in the same pane
- Added support for displaying channel notes in markdown preview
- Added support for displaying the current active editor when opening
markdown preview
- Added support for scrolling the editor to the corresponding block when
double clicking an element in markdown preview
- Improved pane creation handling when opening markdown preview
- Fixed markdown preview displaying non-markdown files
This PR removes the `full` style method and replaces it with
`size_full`, as the two do the same thing.
This is the generated code for `size_full`:
```rs
#[doc = "Sets the width and height of the element.\n\n100%"]
fn size_full(mut self) -> Self {
let style = self.style();
style.size.width = Some((gpui::relative(1.)).into());
style.size.height = Some((gpui::relative(1.)).into());
self
}
```

This PR improves support for rendering markdown documents.
## After the updates
https://github.com/zed-industries/zed/assets/18583882/48315901-563d-44c6-8265-8390e8eed942
## Before the updates
https://github.com/zed-industries/zed/assets/18583882/6d7ddb55-41f7-492e-af12-6ab54559f612
## New features
- @SomeoneToIgnore's [scrolling feature
request](https://github.com/zed-industries/zed/pull/6958#pullrequestreview-1850458632).
- Checkboxes (`- [ ]` and `- [x]`)
- Inline code blocks.
- Ordered and unordered lists at an arbitrary depth.
- Block quotes that render nested content, like code blocks.
- Lists that render nested content, like code blocks.
- Block quotes that support variable heading sizes and the other
markdown features added
[here](https://github.com/zed-industries/zed/pull/6958).
- Users can see and click internal links (`[See the docs](./docs.md)`).
## Notable changes
- Removed dependency on `rich_text`.
- Added a new method for parsing markdown into renderable structs. This
method uses recursive descent so it can easily support more complex
markdown documents.
- Parsing does not happen for every call to
`MarkdownPreviewView::render` anymore.
## TODO
- [ ] Typing should move the markdown preview cursor.
## Future work under consideration
- If a title exists for a link, show it on hover.
- Images.
- Since this PR brings the most support for markdown, we can consolidate
`languages/markdown` and `rich_text` to use this new renderer. Note that
the updated inline text rendering method in this PR originated from
`langauges/markdown`.
- Syntax highlighting in code blocks.
- Footnote references.
- Inline HTML.
- Strikethrough support.
- Scrolling improvements:
- Handle automatic preview scrolling when multiple cursors are used in
the editor.
- > great to see that the render now respects editor's scrolls, but can
we also support the vice-versa (as syntax tree does it in Zed) — when
scrolling the render, it would be good to scroll the editor too
- > sometimes it's hard to understand where the "caret" on the render
is, so I wonder if we could go even further with its placement and place
it inside the text, as a regular caret? Maybe even support the
selections?
- > switching to another markdown tab does not change the rendered
contents and when I call the render command again, the screen gets
another split — I would rather prefer to have Zed's syntax tree
behavior: there's always a single panel that renders things for whatever
tab is active now. At least we should not split if there's already a
split, rather adding the new rendered tab there.
- > plaintext URLs could get a highlight and the click action
## Release Notes
- Improved support for markdown rendering.
Adds a "markdown: open preview" action to open a markdown preview.
https://github.com/zed-industries/zed/assets/18583882/6fd7f009-53f7-4f98-84ea-7dd3f0dd11bf
This PR extends the work done in `crates/rich_text` to render markdown
to also support:
- Variable heading sizes
- Markdown tables
- Code blocks
- Block quotes
## Release Notes
- Added `Markdown: Open preview` action to partially close
([#6789](https://github.com/zed-industries/zed/issues/6789)).
## Known issues that will not be included in this PR
- Images.
- Nested block quotes.
- Footnote Reference.
- Headers highlighting.
- Inline code highlighting (this will need to be implemented in
`rich_text`)
- Checkboxes (`- [ ]` and `- [x]`)
- Syntax highlighting in code blocks.
- Markdown table text alignment.
- Inner markdown URL clicks
