Previously, we were using `PostThreadMessage` to pass messages to
`WindowsPlatform`. This PR switches to an approach similar to `winit`
which using a hidden window as the message window (I guess that’s why
winit uses a hidden window?). The difference is that this PR creates it
as a message-only window.
Thanks to @reflectronic for the original PR #37255, this implementation
just fits better with the current code style.

This PR fixes a typo in the Windows alpha correction shader that is now
caught by https://github.com/zed-industries/zed/pull/37314.
Another case that could be addressed by Bors.

Closes#36023
This improves font rendering quality by doing perceptual gamma+contrast
correction which makes font edges look nicer and more legible.

This is most noticeable on smaller fonts / low-dpi displays
Release Notes:
- Improved font rendering quality
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.
Release Notes:
- Fixed ligatures forming between real text and inlay hints on macOS
Follow up of https://github.com/zed-industries/zed/pull/33334
After chatting with @MrSubidubi we found out that he had an old defaults
setting (most likely from when he encountered a previous window tabbing
bug):
```
❯ defaults read dev.zed.Zed-Nightly
{
NSNavPanelExpandedSizeForOpenMode = "{800, 448}";
NSNavPanelExpandedSizeForSaveMode = "{800, 448}";
NSNavPanelExpandedStateForSaveMode = 1;
NSOSPLastRootDirectory = {length = 828, bytes = 0x626f6f6b 3c030000 00000410 30000000 ... dc010000 00000000 };
"NSWindow Frame NSNavPanelAutosaveName" = "557 1726 800 448 -323 982 2560 1440 ";
"NSWindowTabbingShoudShowTabBarKey-GPUIWindow-GPUIWindow-(null)-HT-FS" = 1;
}
```
> That suffix is AppKit’s fallback autosave name when no tabbing
identifier is set. It encodes the NSWindow subclass (GPUIWindow), plus
traits like HT (hidden titlebar) and FS (fullscreen).
Which explains why it only happened on the Nightly build, since each
bundle has it's own defaults. It also explains why the tabbar would
disappear when he activated the `use_system_window_tabs` setting,
because with that setting activated, the tabbing identifier becomes
"zed" (instead of the default one when omitted) for which he didn't have
the `NSWindowTabbingShoudShowTabBarKey` default.
The original implementation was perhaps a bit naive and relied fully on
macOS to determine if the tabbar should be shown. I've updated the code
to always hide the tabbar, if the setting is turned off and there is
only 1 tab entry.
While testing, I also noticed that the menu's like 'merge all windows'
wouldn't become active when the setting was turned on, only after a full
workspace reload. So I added a setting observer as well, to immediately
set the correct window properties to enable all the features without a
reload.
Release Notes:
- N/A
This pull request refactors the `KeybindingKeystroke` struct and related
code to improve platform abstraction. The changes centralize
platform-specific logic within `KeybindingKeystroke` and update its
usage throughout the codebase, making the API more consistent and less
error-prone.
Release Notes:
- N/A
Closes#36300
This PR follows Windows conventions by introducing
`KeybindingKeystroke`, so shortcuts now show up as `ctrl-shift-4`
instead of `ctrl-$`.
It also fixes issues with keyboard layouts: when `use_key_equivalents`
is set to true, keys are remapped based on their virtual key codes. For
example, `ctrl-\` on a standard English layout will be mapped to
`ctrl-ё` on a Russian layout.

This removes around 900 unnecessary clones, ranging from cloning a few
ints all the way to large data structures and images.
A lot of these were fixed using `cargo clippy --fix --workspace
--all-targets`, however it often breaks other lints and needs to be run
again. This was then followed up with some manual fixing.
I understand this is a large diff, but all the changes are pretty
trivial. Rust is doing some heavy lifting here for us. Once I get it up
to speed with main, I'd appreciate this getting merged rather sooner
than later.
Release Notes:
- N/A
Closes#36229
Fix zero-sized texture creation that triggers a SIGABRT in the Metal
renderer. Not sure why this happens yet, but it likely occurs when
`native_window.contentView()` returns a zero `NSSize` during initial
window creation, before the view size is computed.
Release Notes:
- Fixed a rare startup crash on macOS.
Closes#24672
This PR complements a feature added earlier by @JosephTLyons (in
https://github.com/zed-industries/zed/pull/32353) where the text is
considered as the tab title in a new buffer. It piggybacks off that
change and sets the title as the suggested filename in the save dialog
(completely mirroring the same functionality in VSCode):

Release Notes:
- Text entered in a new untitled buffer is considered as the default
filename when saving
Closes#29083
On X11, `ibus-x11` crashes on some distros after Zed interacts with it.
This is not unique to Zed, `xim-rs` shows the same behavior, and there
are similar upstream `ibus` reports with apps like Blender:
- https://github.com/ibus/ibus/issues/2697
I opened an upstream issue to track this:
- https://github.com/ibus/ibus/issues/2789
When this crash happens, we don’t get a disconnect event, so Zed keeps
sending events to the IM server and waits for a response. It works on
subsequent starts because IM server doesn't exist now and we default to
non-XIM path.
This PR detects the crash via X11 events and falls back to the non-XIM
path so typing keeps working. We still need to investigate whether the
root cause is in `xim-rs` or `ibus-x11`.
Release Notes:
- Fixed an issue on X11 where keyboard input sometimes didn’t work on
first start.
The Zed Plex fonts were found to violate the OFL by using the word Plex
in the name.
Lilex has better ligatures and box-drawing characters than Zed Plex
Mono, but Zed Plex Sans should be identical
to IBM Plex Sans.
Closes#15542Closeszed-industries/zed-fonts#31
Release Notes:
- The "Zed Plex Sans" and "Zed Plex Mono" fonts have been replaced with
"IBM Plex Sans" and "Lilex". The old names still work for backward
compatibility. Other than fixing line-drawing characters, and improving
the ligatures, there should be little visual change as the fonts are all
of the same family.
- Introduced ".ZedSans" and ".ZedMono" as aliases to allow us to easily
change the default fonts in the future. These currently default to "IBM
Plex Sans" and "Lilex" respectively.
Closes#34374
This is a leftover issue from #34374. Back in #34374, I wanted to use
DirectX to handle vsync, after all, that’s how 99% of Windows apps do
it. But after discussing with @maxbrunsfeld , we decided to stick with
the original vsync approach given gpui’s architecture.
In my tests, there’s no noticeable performance difference between this
PR’s approach and DirectX vsync. That said, this PR’s method does have a
theoretical advantage, it doesn’t block the main thread while waiting
for vsync.
The only difference is that in this PR, on Windows 11 we use a newer API
instead of `DwmFlush`, since Chrome’s tests have shown that `DwmFlush`
has some problems. This PR also removes the use of
`MsgWaitForMultipleObjects`.

In the same vein as #29538, the "Services" menu on macOS depended on the
text being exactly "Services", not allowing for i18n of the menu name.
This PR introduces a new menu type called `OsMenu` that defines a
special menu that can be populated by the system. Currently, it takes
one enum value, `ServicesMenu` that tells the system to populate its
contents with the items it would usually populate the "Services" menu
with.
An example of this being used has been implemented in the `set_menus`
example:
`cargo run -p gpui --example set_menus`
---
Point to consider:
In `mac/platform.rs:414` the existing code for setting the "Services"
menu remains for backwards compatibility. Should this remain now that
this new method exists to set the menu, or should it be removed?

This reverts commit efba2cbfd3.
Unfortunately, the Docker image for 1.89 has not shown up yet. Once it
has, we should re-land this.
Release Notes:
- N/A
Fixes a regression introduced in
https://github.com/zed-industries/zed/pull/34992
### Background
Paths are rendered first to an intermediate MSAA texture, and then
copied to the final drawable. Because paths can have transparency, it's
important that pixels are not copied repeatedly if paths have
overlapping bounding boxes. When N paths have the same draw order, we
infer that they must have disjoint bounding boxes, so that we can copy
them each individually (as opposed to copying a single rect that
contains them all). Previously, the bounding box that we were using to
copy paths was not accounting for the path's content mask (but it is
accounted for in the bounds tree that determines their draw order).
This cause bugs like this, where certain path pixels spuriously had
their opacity doubled:
https://github.com/user-attachments/assets/d792e60c-790b-49ad-b435-6695daba430f
This PR fixes that bug.
* [x] mac
* [x] linux
* [x] windows
Release Notes:
- Fixed a bug where a selection's opacity was computed incorrectly when
it overlapped with another editor's selections in a certain way.
Fixes https://github.com/zed-industries/zed/issues/33257
Previously, the scale-factor-change-handling logic relied on
`SetWindowPos` enqueuing a `WM_SIZE` window event. But that does not
happen when the window is maximized. So when the scale factor changed,
maximized windows neglected to call their `resize` callback, and would
misinterpret the positions of mouse events.
This PR adds special logic for maximized windows, to ensure that the
size is updated appropriately.
Release Notes:
- N/A
This PR doesn't change any logic, it just cleans up some naming and
style in the windows platform layer.
* Rename `WindowsWindowStatePtr` to `WindowsWindowInner`, since it isn't
a pointer type.
* Move window event handler methods into an impl on this type, so that
all of the `state_ptr: &Rc<WindowsWindowInner>` parameters can just be
replaced with `&self`.
* In window creation, use a `match` instead of a conditional followed by
an unwrap
There's a lot of whitespace in the diff, so view it with `w=1`.
Release Notes:
- N/A
This allows debugging Zed with Renderdoc, and also fixes an issue where
glyphs' bounds were miscalculated for certain sizes and scale factors.

Closes#35316
Bug in https://github.com/zed-industries/zed/pull/34514
Turns out you are not supposed to call `update_key` for modifiers on
`KeyPress`/`KeyRelease`, as modifiers are already updated in
`XkbStateNotify` events. Not sure why this only causes issues on a few
systems and works on others.
Tested on Ubuntu 24.04.2 LTS (initial bug) and Kubuntu 25.04 (worked
fine before too).
Release Notes:
- Fixed an issue where caps lock stopped working consistently on some
Linux X11 systems.
