The issues is that the closure supplied to `request_measured_layout`
could be run multiple times with differing `known_dimensions`. This in
turn will mean we truncate the font runs once, inserting a multibyte
char at the end but then in the next iteration use those truncated runs
for possible the original untruncated string which has multibyte
characters overlapping the now truncated run end resulting in a faulty
utf8 boundary index.
Solution to this is simple, truncate a clone of the runs when needed
instead of modifying the original.

This shrinks it from roughly a ~kilobyte to 8 byte, removing a bunch of
memmoves emitted by the compiler. Also `Arc`'s it instead of boxing as
we do clone it a couple times here and there, making that also a fair
bit cheaper

Now that we have two surface areas that open as separate windows, it's
important they're consistent with one another. This PR make the settings
UI and rules library windows more similar by having them use the same
minimum window size and similar styles for their navbar given they have
fundamentally the same design (nav on the left and content on the
right).

Closes#39172
This refactors when we resolve UI keybindings in an effort to reduce
flickering whilst painting these: Previously, we would always resolve
these upon creating the binding. This could lead to cases where the
corresponding context was not yet available and no binding could be
resolved, even if the binding was then available on the next presented
frame. Following that, on the next rerender of whatever requested this
keybinding, the keybind for that context would then be found, we would
render that and then also win a layout shift in that process, as we went
from nothing rendered to something rendered between these frames.
With these changes, this now happens less often, because we only look
for the keybinding once the context can actually be resolved in the
window.

Closes#40608
This fixes tabbing in both the settings ui nav bar and page content
going off screen instead of scrolling the focused element into a visible
view.
The bug occurred because `gpui::list` and `gpui::uniform_list` only
render visible elements, preventing non visible elements in a view from
having their focus handle added to the element tree. Thus making the tab
stop map skip over those elements because they weren't present.
The fix for this is scrolling to reveal non visible elements and then
focus the selected element on the next frame.
Release Notes:
- settings ui: Auto scroll to reveal items in navigation bar and window
when tabbing

We very frequently move this in and out of the windows slot map on
`update_window_id` calls (and we call this a lot!). This alone showed up
as `memmove`s at roughly 1% perf in Instruments when scrolling a buffer
which makes sense, `Window` itself is 4kb in size. The fix is simple,
just box the `Window` instances, moving a pointer is cheap in
comparison.

### Problem
On Windows, the right Alt key was not working in keybindings (e.g.,
`Ctrl+Right Alt+B`), while the left Alt key worked correctly. This was
due to overly aggressive AltGr detection that treated any `right Alt +
left Ctrl` combination as AltGr, even on US keyboards where AltGr
doesn't exist.
### Root Cause
Windows internally represents AltGr (Alt Graph) as `right Alt + left
Ctrl` pressed simultaneously. The previous implementation always
excluded this combination from being treated as regular modifier keys to
support international keyboards. However, this broke keybindings using
right Alt on US/UK keyboards where users expect right Alt to behave
identically to left Alt.
### Solution
Implemented keyboard layout-aware AltGr detection:
1. Added `uses_altgr()` method to `WindowsKeyboardLayout` that checks if
the current keyboard layout is known to use AltGr (German, French,
Spanish, Polish, etc.)
2. Modified `current_modifiers()` to only apply AltGr special handling
when the keyboard layout actually uses it
3. Added explicit checking for both `VK_LMENU` and `VK_RMENU` instead of
relying solely on the generic `VK_MENU`
### Behavior
- **US/UK keyboards**: Right Alt now works identically to left Alt in
keybindings. `Ctrl+Right Alt+B` triggers the same action as `Ctrl+Left
Alt+B`
- **International keyboards** (German, French, Spanish, etc.): AltGr
continues to work correctly for typing special characters and doesn't
trigger keybindings
- **All keyboards**: Both Alt keys are detected symmetrically, matching
the behavior of left/right Windows keys
### Testing
Manually tested on Windows with US keyboard layout:
- `Ctrl+Left Alt+B` triggers keybinding
- `Ctrl+Right Alt+B` triggers keybinding
- Both Alt keys work independently in keybindings
Release Notes:
- Fixed Right Alt key not working in keybindings on Windows
We've been considering removing workspace-hack for a couple reasons:
- Lukas ran into a situation where its build script seemed to be causing
spurious rebuilds. This seems more likely to be a cargo bug than an
issue with workspace-hack itself (given that it has an empty build
script), but we don't necessarily want to take the time to hunt that
down right now.
- Marshall mentioned hakari interacts poorly with automated crate
updates (in our case provided by rennovate) because you'd need to have
`cargo hakari generate && cargo hakari manage-deps` after their changes
and we prefer to not have actions that make commits.
Currently removing workspace-hack causes our workspace to grow from
~1700 to ~2000 crates being built (depending on platform), which is
mainly a problem when you're building the whole workspace or running
tests across the the normal and remote binaries (which is where
feature-unification nets us the most sharing). It doesn't impact
incremental times noticeably when you're just iterating on `-p zed`, and
we'll hopefully get these savings back in the future when
rust-lang/cargo#14774 (which re-implements the functionality of hakari)
is finished.

I remember when I was working on CJK line wrapping support in the early
days, I considered making `\` a line wrapping character, but for some
reason it was on the list of characters that were not allowed to wrap.
In reference to VS Code, it looks like `&`, `/`, `?` should wrap, so I
removed all of them.

This is a follow-up PR to
https://github.com/zed-industries/zed/pull/39609, and attempts to
address hidden status bar items still contributing to the layout and
creating extra spacing.

- 203cbd634bfb1489b8afa4952d9594615a956b77 Adds a `.none()` method to
the `gpui::Styled` helper trait, so that status items can set their
display type to none inside their `render` method.
- 249f06e3de63b0ab32814f20e7105d8e2b642f02 Applies `.none()` to all the
status items.
- ~~499f564906c88336608c81615b11ebc9ab43d832~~ At first I was adding an
`is_visible` method to the `StatusBarView` trait, which would be used to
skip status bar items which would just render an empty div anyway, but I
felt duplicating the conditions for hiding the buttons between the
status items `is_visible` and `render` methods could be an attraction
for bugs, so I tried to find another approach. This commit contains
those changes, reverted immediately (if the `is_visible` approach is
preferred I can bring it back!)
- f37cb75f0519ceea1f3e1cc4f97087a5cb34b0fd (bonus!) Adds a condition to
the vim mode indicator to avoid a leading space when there are no
pending keys.

Closes#40359
We were segfaulting when opening a UTF-8 file starting with a byte order
mark due to a mismatch in our UTF-16 indexing calculations caused by
Core Foundations `replace_str` stripping the BOM internally. This PR
fixes the crash by replacing one of our manual calculations by calling
the Core Foundations API to get the length of a string.

- Fixed a crash on macOS when opening a file that starts with a UTF-8
byte order mark (BOM).

This PR improves the rendering performance of the Settings UI window by
using `gpui::list` to render only the visible contents of a settings
page, instead of rendering the full content of a page. This fixes a lag
that the editor page has in debug builds.
I also added a new field `measuring_behavior` to `ListState` that has
`Visible` and `Measured` variances. `Visible` only measures and caches
the bounds of visible items plus the overdraw pixel offset. `Measure`
will cache all items’ bounds on the first layout phase, which fixes
problems with the scrollbar size/position being miscalculated.

This applies the same fix as #39886 for Windows.
Previously we were using `GetLineMetrics` to determine the ascent and
descent values for each line. It seems like this has the same behavior
as `GetTypographicBounds` on macOS, which is to return the minimum
ascent and descent for the current state of the `TextLayout` object.
This causes the ascent/descent to be unstable when adding or removing an
emoji because a font fallback is triggered when an emoji is present on
the line.
The issue is fixed by switching to `font.GetMetrics` to get the ascent
and descent, which should always return stable values for the main font,
instead of changing when there's a fallback. This also should support
situations where we have multiple explicit fonts on the same line,
although that probably can't be triggered in Zed right now.
Release Notes:
- windows: Fixed a vertical shift in text layout when inserting or
removing an emoji.

This relands https://github.com/zed-industries/zed/pull/37175 as
https://github.com/zed-industries/zed/pull/39886 fixed the jiggling
issue.
Currently when we render text with differing styles adjacently we might
form a ligature between the text, causing the ligature forming
characters to take on one of the two styles. This can especially become
confusing when a ligature is formed between actual text and inlay hints.
Annoyingly, the only ways to prevent this with core text is to either
render each run separately, or to insert a zero-width non-joiner to
force core text to break the ligatures apart, as it otherwise will merge
subsequent font runs of the same fonts.
We currently do layouting on a per line basis and it is unlikely we want
to change that as it would incur a lot of complexity and annoyances to
merge things back into a line, so this goes with the other approach of
inserting ZWNJ characters instead.
Note that neither linux nor windows seem to currently render ligatures,
so this only concerns macOS rendering at the moment.
Closes https://github.com/zed-industries/zed/issues/23194
Release Notes:
- Fixed ligatures forming between real text and inlay hints on macOS
