Here's some backstory:
* on macOS, @cole-miller and I noticed that since roughly Oct 2025, due
to some changes to latest macOS Tahoe, for any spawned child process we
needed to reset Mach exception ports
(https://github.com/zed-industries/zed/issues/36754 +
https://github.com/RemiKalbe/zed/commit/6e8f2d2ebe5a93753625a3026aeb996de8cb436b)
* the changes in that PR achieve that via `pre_exec` hook on
`std::process::Command` which then abandons `posix_spawn` syscall for
`fork` + `execve` dance on macOS (we tracked it down in Rust's std
implementation)
* as it turns out, `fork` + `execve` is pretty expensive on macOS
(apparently way more so than on other OSes like Linux) and `fork` takes
a process-wide lock on the allocator which is bad
* however, since we wanna reset exception ports on the child, the only
official way supported by Rust's std is to use `pre_exec` hook
* posix_spawn on macOS exposes this tho via a macOS specific extension
to that syscall `posix_spawnattr_setexceptionports_np` but there is no
way to use that via any standard interfaces in `std::process::Command`
* thus, it seemed like a good idea to instead create our own custom
Command wrapper that on non-macOS hosts is a zero-cost wrapper of
`smol::process::Command`, while on macOS we reimplement the minimum to
achieve `smol::process::Command` with `posix_spawn` under-the-hood
Notably, this changeset improves git-blame in very large repos
significantly.
Release Notes:
- Fixed performance spawning child processes on macOS by always forcing
`posix_spawn` no matter what.

### Summary
Adds accept/reject tracking for Mercury edit predictions.
### Changes
Sends events to https://api-feedback.inceptionlabs.ai/feedback when:
Accept — user presses Tab
Reject — user presses Escape
Ignore — prediction dismissed implicitly (typing, cursor move, etc.)
Added `discard_explicit` method to the delegate trait to distinguish
explicit vs implicit dismissal. Updated `reject_prediction` and
`reject_current_prediction` methods with an `explicit` bool parameter to
thread this through to the Mercury feedback logic. Other providers are
unaffected—they use the default implementation.
Feedback is fire-and-forget in a background thread, only sent for
predictions that were shown.
### Data Collected
- Request ID (returned from Inception API)
- User action (either accept/reject/ignore)
- Client Zed version (to track updates made to Zed client which could
potentially affect nextedit implementation)
Release Notes:
- N/A

This PR removes the ability to retrieve a Supermaven API key from
Collab.
This was staff-gated (at least, on the server), and judging by the logs,
no one is using it.
Release Notes:

This PR introduces support for Next Edit Suggestions while doing away
with calling legacy endpoints. In the process we've also removed support
for cycling completions, as NES will give us a single prediction, for
the most part.
Closes#30124
Release Notes:
- Zed now supports Copilot's [Next Edit
Suggestions](https://code.visualstudio.com/blogs/2025/02/12/next-edit-suggestions).
When no predictions are available for the current buffer, we will now
attempt to predict at the closest diagnostic from the cursor location
that wasn't included in the last prediction request. This enables a
commonly desired kind of far-away jump without requiring explicit model
support.
Release Notes:
- N/A
Closes#36981
- Add completion text and position caching to reduce redundant API calls
- Only trigger new completion requests on text changes, not cursor
movement
- Validate cursor position to ensure completions show at correct
location
- Improve end-of-line range calculation for more accurate deletions
- Extract reset_completion_cache helper for cleaner code organization
- Update completion diff algorithm documentation for clarity
Edit: Sorry this is the 2nd PR, I forgot that the forks history was
messy; I cherrypicked and cleaned it properly with this PR
Release Notes:
- supermaven: Improved caching of predictions
- supermaven: Fixed an issue where changing cursor position would
incorrectly trigger new completions
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
This pull request introduces changes to improve the behavior and
consistency of multiple completion providers
(`CopilotCompletionProvider`, `SupermavenCompletionProvider`) and their
integration with UI elements like menus and inline completion buttons.
It now allows to see the prediction with the completion menu open whilst
pressing `opt` and also enables the subtle/eager setting that was
introduced with zeta.

(still learning rust)
Release Notes:
- Added Subtle and Eager edit prediction modes to Copilot and Supermaven

Adds a new `documentation` method to actions, that is extracted from doc
comments when using the `actions!` or derive macros.
Additionally, this PR adds doc comments to as many action definitions in
Zed as possible.

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
Release Notes:
- N/A
This PR updates the edit predictions to include the prediction ID
returned from the server on the resulting telemetry events indicating
whether the prediction was accepted or discarded.
The `prediction_id` on the events can then be correlated with the
`request_id` on the server-side prediction events.
Release Notes:
- N/A
- [x] snake case keymap properties
- [x] flatten actions
- [x] keymap migration + notfication
- [x] settings migration + notification
- [x] inline completions -> edit predictions
### future:
- keymap notification doesn't show up on start up, only on keymap save.
this is existing bug in zed, will be addressed in seperate PR.
Release Notes:
- Added a notification for deprecated settings and keymaps, allowing you
to migrate them with a single click. A backup of your existing keymap
and settings will be created in your home directory.
- Modified some keymap actions and settings for consistency.

* When an edit prediction is present in non-insertion modes, hide it but
show `tab Jump to edit`.
* Removes discarding of edit predictions when going from insert mode to
normal mode, instead just hide them in non-insertion modes.
* Removes zeta-specific showing of predictions in normal mode. This
behavior was only happening in special cases anyway - where the discard
of completions wasn't happening due to some other thing taking
precedence in `dismiss_menus_and_popups`.

Fix a bug where a GPUI macro still used `ModelContext`
Rename `AsyncAppContext` -> `AsyncApp`
Rename update_model, read_model, insert_model, and reserve_model to
update_entity, read_entity, insert_entity, and reserve_entity
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
### issues post merge
- [x] Issues switching between normal and insert mode

This fixes the issue described in this comment:
https://github.com/zed-industries/zed/pull/22439#issuecomment-2563896422
Essentially, we'd clip in the wrong direction when there were multi-line
inlay hints.
It also fixes inline completions for non-Zeta-providers showing up in
normal mode.
Release Notes:
- N/A
This changes #22093 by making the change only have an effect for the
supported provider: Zeta.
Made the change because the UX is still experimental and I don't want to
break existing workflows for Copilot/Supermaven users.
Even Zeta users can opt-out of it by setting
`"show_inline_completions_in_menu": false` in their settings, in case
they want the old show-inline-completion-or-show-lsp-completion behavior
back.
Release Notes:
- N/A
This PR extracts the `InlineCompletionProvider` trait and its related
types out of `editor` and into a new `inline_completion` crate.
By doing so we're able to remove a dependency on `editor` from the
`copilot` and `supermaven` crates.
We did have to move `editor::Direction` into the `inline_completion`
crate, as it is referenced by the `InlineCompletionProvider`. This
should find a better home, at some point.
Release Notes:
- N/A
Caps the size of the Supermaven states buffer to 1000 elements.
Previously, the buffer would grow unbounded so for long sessions the
number of states that the Supermaven autocomplete provider maintains can
be quite large. In practice, states that are sufficiently old are so
unlikely to be visited again that we can regenerate the completion.
Thus, we can cap the buffer to 1000 elements.
Release Notes:
- N/A
Closes https://github.com/zed-industries/zed/issues/8534
Supersedes https://github.com/zed-industries/zed/pull/16349
Potential concerns:
* we do not follow up to the `/` when looking for `.editorconfig`, only
up to the worktree root.
Seems fine for most of the cases, and the rest should be solved
generically later, as the same issue exists for settings.json
* `fn language` in `AllLanguageSettings` is very hot, called very
frequently during rendering. We accumulate and parse all `.editorconfig`
file contents beforehand, but have to go over globs and match these
against the path given + merge the properties still.
This does not seem to be very bad, but needs more testing and
potentially some extra caching.
Release Notes:
- Added .editorconfig support

Closes#19051Closes#19182
#### How to reproduce this crash:
1. Open any file and input some ASCII characters.
2. Replace these characters with `你好`.
3. Press `backspace`.
4. Crash.
https://github.com/user-attachments/assets/ea5c5340-29a5-42c8-98c5-6e60770445a4
The issue lies with the `prefix_offset` introduced in #18858. After the
buffer is modified, this value is not always valid and may fall within a
`char boundary`, which results in a crash.
Release Notes:
- Fixed Supermaven crashing on deleting non-ASCII text
Track the cursor offset before biasing in the Supermaven completion
provider to better determine if the text should be suggested. The
underlying issue here is due to the way anchor biasing works, the
completion provider is not able to determine if a given suggestion's
cursor location no longer exists as it is always coalesced to a correct
location (specifically, the end of the line).
This change updates that logic so the offset is stored independently of
the buffer so it can be used to represent a location that may not exist
in the buffer anymore to represent locations that have been deleted.
The net effect is that suggestions can be backspaced much more cleanly
with Supermaven.
Release Notes:
- Improves https://github.com/zed-industries/zed/issues/17981 to prevent
suggesting completions based on out-of-date cursor locations.
Updates the inline completion provider to return a completion proposal
which is then converted to a completion state. This completion proposal
includes more detailed information about which inlays specifically
should be rendered.
Release Notes:
- Added support for fill-in-the-middle style inline completions
Closes#16194
This PR introduces the following changes:
1. Updated the download process to retrieve the `.exe` file, as the API
response indicates that the `.exe` file should be downloaded on Windows.
> API response:
"https://supermaven-public.s3.amazonaws.com/sm-agent/26/windows/amd64/sm-agent.exe"
2. Modified the startup behavior of supermaven to prevent the cmd window
from appearing.
Release Notes:
- N/A
Sets the account status state to allow the Supermaven button to move out
of the "Supermaven is initializing..." state. We also need to add the
ability to sign out and change tiers but I will do that in a separate
PR.
Release Notes:
- Improved Supermaven status messages
([#12715](https://github.com/zed-industries/zed/issues/12715)).
I'm not a huge fan of passing around a boolean all around the place, but
this will tame the events for now until we have a better solution.
