Hey! I am not sure if this is something that's been considered before
and decided against (I couldn't find any PR's or issues).
This change removes the internal profiling macros in library crates and
the `puffin` feature and replaces it with similar functions in the
[profiling](https://github.com/aclysma/profiling) crate. This crate
provides a layer of abstraction over various profiler instrumentation
crates and allows library users to pick their favorite (supported)
profiler.
An additional benefit for puffin users is that dependencies of egui are
included in the instrumentation output too (mainly wgpu which uses the
profiling crate), so more details might be available when profiling.
A breaking change is that instead of using the `puffin` feature on egui,
users that want to profile the crate with puffin instead have to enable
the `profile-with-puffin` feature on the profiling crate. Similarly they
could instead choose to use `profile-with-tracy` etc.
I tried to add a 'tracy' feature to egui_demo_app in order to showcase ,
however the /scripts/check.sh currently breaks on mutually exclusive
features (which this introduces), so I decided against including it for
the initial PR. I'm happy to iterate more on this if there is interest
in taking this PR though.

puffin
This moves `egui::util::cache` to `egui::cache` (the old path is
deprecated, but still works).
It also adds the `FramePublisher` helper, which can be used to publish a
value which will be retained for this frame and the next:
``` rs
pub type MyPublisher = egui::cache::FramePublisher<MyKey, MyValue>;
// Publish:
ctx.memory_mut(|mem| {
mem.caches.cache::<MyPublisher>().set(key, value);
});
// Retrieve:
let value: Option<MyValue> = ctx.memory_mut(|mem| {
mem.caches
.cache::<MyPublisher>()
.get(key)
.clone()
})
```

I removed the webp supported URI test given that the webp feature would
have to be enabled. I kept that webp is not supported in the other
tests.
There might need to be an additional warning in the changelog that image
support detection is now stricter.
This will allow disabling the animation that occurs during
`scroll_to_row` calls. Follows the same coding style as the other scroll
options in `TableBuilder`.

Unfortunately, this PR contains a bunch of breaking changes because
`Context` no longer has one style, but two. I could try to add some of
the methods back if that's desired.
The most subtle change is probably that `style_mut` mutates both the
dark and the light style (which from the usage in egui itself felt like
the right choice but might be surprising to users).
I decided to deviate a bit from the data structure suggested in the
linked issue.
Instead of this:
```rust
pub theme: Theme, // Dark or Light
pub follow_system_theme: bool, // Change [`Self::theme`] based on `RawInput::system_theme`?
```
I decided to add a `ThemePreference` enum and track the current system
theme separately.
This has a couple of benefits:
* The user's theme choice is not magically overwritten on the next
frame.
* A widget for changing the theme preference only needs to know the
`ThemePreference` and not two values.
* Persisting the `theme_preference` is fine (as opposed to persisting
the `theme` field which may actually be the system theme).
The `small_toggle_button` currently only toggles between dark and light
(so you can never get back to following the system). I think it's easy
to improve on this in a follow-up PR :)
I made the function `pub(crate)` for now because it should eventually be
a method on `ThemePreference`, not `Theme`.
To showcase the new capabilities I added a new example that uses
different "accent" colors in dark and light mode:

The syntax highlighting font size was always hardcoded to 12 or 10
depending on what case it was hitting (so not consistent). This is
particularly noticeable when you increase the font size to something
larger for the rest of the ui.
With this the default monospace font size is used by default.
Since the issue is closely related to #3549 I decided to implement the
ability to use override_font_id too.
## Visualized
Default monospace is set to 15 in all the pictures
Before/After without syntect:
Before/after _with_ syntect:
Font override after without/with syntect (monospace = 20):
### Breaking changes
- `CodeTheme::dark` and `CodeTheme::light` takes in the font size
- `CodeTheme::from_memory` takes in `Style`
- `highlight` function takes in `Style`

I added a util function `set_hovered` to change the hovered state of a
row from tables in `egui_extras` which matches the already present
`set_selected` function.
* [x] I have followed the instructions in the PR template
`egui::Table` has a weirdly specific default `max_scroll_height` set to
800.0. This means that even with `vscroll(true)` and `auto_shrink([_,
false])`, the table will not expend to the full available height. This
PR changes this value to `f32::INFINITY`. This makes it consistent with
the corresponding default value of `ScrollArea::max_size.y`, which is
where that `max_scroll_height` ends up being used.
This makes the sizing pass of an `egui_table` ensure the table uses as
little width as possible.
Subsequently, it will redistribute all non-resizable columns on the
available space, so that a table better follow the parent container as
it is resized.
I also added `table.reset()` for forgetting the current column widths.

All the other crates in egui have serde as an optional dependency -
which is great! But sadly egui_extras unconditionally includes it, which
adds a bunch of code to stuff that may not care for it. This PR gates
serde support behind a new `serde` feature.
This is a breaking change; if that's undesirable then we can add it as a
default feature instead, though that wouldn't match any of the other
crates.
* Closes https://github.com/emilk/egui/issues/4535
This should improve the auto-sizing of columns when nesting expanding
widgets (e.g. `Separator`), or centered or justified layouts.
* Closes#4534
This PR:
- Introduces `Ui::stack()`, which returns the `UiStack` structure
providing information on the current `Ui` hierarchy.
- **BREAKING**: `Ui::new()` now takes a `UiStackInfo` argument, which is
used to populate some of this `Ui`'s `UiStack`'s fields.
- **BREAKING**: `Ui::child_ui()` and `Ui::child_ui_with_id_source()` now
take an `Option<UiStackInfo>` argument, which is used to populate some
of the children `Ui`'s `UiStack`'s fields.
- New `Area::kind()` builder function, to set the `UiStackKind` value of
the `Area`'s `Ui`.
- Adds a (minimalistic) demo to egui demo (in the "Misc Demos" window).
- Adds a more thorough `test_ui_stack` test/playground demo.
TODO:
- [x] benchmarks
- [x] add example to demo
Future work:
- Add `UiStackKind` and related support for more container (e.g.
`CollapsingHeader`, etc.)
- Add a tag/property system that would allow adding arbitrary data to a
stack node. This data could then be queried by nested `Ui`s. Probably
needed for #3284.
- Add support to track columnar layouts.

Related to #3482
Not sure what the "best practice" is, to me it seems like one should
import from "the original location" if possible, but now it should at
least be possible to not re-export ahash without any breakage in the
egui code base (but possibly in projects using egui, so one should
probably deprecate it if one would like to go that path). It also seems
like epaint re-exports ahash.
Removes `egui_assert` etc and replaces it with normal `debug_assert`
calls.
Previously you could opt-in to more runtime checks using feature flags.
Now these extra runtime checks are always enabled for debug builds.
You are most likely to encounter them if you use negative sizes or NaNs
or other similar bugs.
These usually indicate bugs in user space.
Motivation: I want to replace `cargo-cranky` with workspace lints, first
available in Rust 1.74.
However, `cargo doc` would hange on `wgpu` and `wgpu-core` on 1.74 and
1.75… so now we're on 1.76.
I think this is fine - when 1.78 is released next week we're still two
versions behind the bleeding edge.
…and the branch name is just wrong 🤦
I added a handfull of lines to allow for the red highlight on weekends
in `DatePickerPopup` to be disabled.
I tried to follow the rules, but I've never done any kind of PR before,
and I'm also not sure if this is at all the kind of thing that is wanted
at the moment. If it is not, I'm happy to just have this removed. Just a
tiny little addition I would find useful.

Simply allows date picker buttons to show other formats than `%Y-%m-%d`,
while keeping that as default to not break compatibility.
I'm not that experienced with Rust, so I was unsure whether you'd prefer
`&'a str` rather than a `String`, let me know if I should change that.

* Remove the leading slash from the path if the target OS is Windows.
This is because Windows paths are not supposed to start with a slash.
For example, `file:///C:/path/to/file` is a valid URI, but
`/C:/path/to/file` is not a valid path.
* Use the input URI consistently as the cache key.
Currently, the cache key is inconsistently set as either the path or the
URI, while the forget key is always the URI. This inconsistency should
be resolved.

Each cell in a table now has a `Ui` with a unique `Id` based on the row
and column.
This avoids Id-clashes, e.g. when putting a `CollapsingHeader` in a
table cell.
* Closes https://github.com/emilk/egui/issues/3936

* Closes https://github.com/emilk/egui/pull/4058
The interaction code is now done at the start of the frame, using stored
`WidgetRect`s from the previous frame.
The intention is that the new interaction code should be more accurate,
making it easier to hit widgets, and better respecting the rules of
overlapping widgets.
There is a new `style::Interaction::interact_radius` controlling how far
away from a widget the cursor can be and still hit it. This helps big
fat fingers hit small widgets on touch screens.
This PR adds a new `Context::read_response` which lets you read the
`Response` of a `Widget` _before_ you create the widget. This can be
used for styling, or for reading the result of an interaction early (to
prevent frame-delay) for a widget you add late (so it is on top of other
widgets).
# ⚠️ BREAKING CHANGES
`Memory::dragged_id`, `Memory::set_dragged_id` etc have been moved to
`Context`.
The semantics for `Context::dragged_id` is slightly different: a widget
is not considered dragged until egui it is sure this is not a
click-in-progress. For a widget that is only sensitive to drags, that is
right away, but for widgets sensitive to both clicks and drags it is not
until the mouse has moved a certain distance.

* [x] Fix scroll hover weirdness
* [x] Fix Resize widget
* [x] Fix drag-and-drop

I think both these can be fixed if each `Ui` registers themselves as a
`WidgetRect`, with the possibility to interact with it later, as if the
interaction was under all widgets on top of it.
There was no way to customize this as ScrollArea gets created inside
Table widget, this exposes the functionality, so scroll bars on tables
can be customized.
