Closes https://github.com/zed-industries/zed/issues/23981
Release Notes:
- Fixed a crash that could happen when expanding certain diff hunks
- Fixed a bug where diff hunks were not syntax highlighted when
reopening a project with previously-opened buffers.
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#12553
* [x] Fix `diff_hunk_before`
* [x] Fix failure to show deleted text when expanding hunk w/ cursor on
second line of the hunk
* [x] Failure to expand diff hunk below the cursor.
* [x] Delete the whole file, and expand the diff. Backspace over the
deleted hunk, panic!
* [x] Go-to-line now counts the diff hunks, but it should not
* [x] backspace at the beginning of a deleted hunk deletes too much text
* [x] Indent guides are rendered incorrectly
* [ ] Fix randomized multi buffer tests
Maybe:
* [ ] Buffer search should include deleted text (in vim mode it turns
out I use `/x` all the time to jump to the next x I can see).
* [ ] vim: should refuse to switch into insert mode if selection is
fully within a diff.
* [ ] vim `o` command when cursor is on last line of deleted hunk.
* [ ] vim `shift-o` on first line of deleted hunk moves cursor but
doesn't insert line
* [x] `enter` at end of diff hunk inserts a new line but doesn't move
cursor
* [x] (`shift-enter` at start of diff hunk does nothing)
* [ ] Inserting a line just before an expanded hunk collapses it
Release Notes:
- Improved diff rendering, allowing you to navigate with your cursor
inside of deleted text in diff hunks.

First, parse the output of `git status --porcelain=v1` into a
representation that can handle the full "grammar" and doesn't lose
information.
Second, as part of pushing this throughout the codebase, expand the use
of the existing `GitSummary` type to all the places where status
propagation is in play (i.e., anywhere we're dealing with a mix of files
and directories), and get rid of the previous `GitSummary ->
GitFileStatus` conversion.

This is a pure refactor of our Git diff state management. Buffers are no
longer are associated with one single diff (the unstaged changes).
Instead, there is an explicit project API for retrieving a buffer's
unstaged changes, and the `Editor` view layer is responsible for
choosing what diff to associate with a buffer.
The reason for this change is that we'll soon want to add multiple "git
diff views" to Zed, one of which will show the *uncommitted* changes for
a buffer. But that view will need to co-exist with other views of the
same buffer, which may want to show the unstaged changes.
### Todo
* [x] Get git gutter and git hunks working with new structure
* [x] Update editor tests to use new APIs
* [x] Update buffer tests
* [x] Restructure remoting/collab protocol
* [x] Update assertions about staged text in
`random_project_collaboration_tests`
* [x] Move buffer tests for git diff management to a new spot, using the
new APIs

Closes https://github.com/zed-industries/zed/issues/12029
Allows to introspect project items inside items more deeply, checking
them for being dirty.
For that:
* renames `project::Item` into `project::ProjectItem`
* adds an `is_dirty(&self) -> bool` method to the renamed trait
* changes the closing logic to only care about dirty project items when
checking for save prompts conditions
* save prompts are raised only if the item is singleton without a
project path; or if the item has dirty project items that are not open
elsewhere
Release Notes:
- Fixed item closing overly triggering save dialogues
Closes https://github.com/zed-industries/zed/issues/4351

Applies the same splitting mechanism, as Zed's central pane has, to the
terminal panel.
Similar navigation, splitting and (de)serialization capabilities are
supported.
Notable caveats:
* zooming keeps the terminal splits' ratio, rather expanding the
terminal pane
* on macOs, central panel is split with `cmd-k up/down/etc.` but `cmd-k`
is a "standard" terminal clearing keybinding on macOS, so terminal panel
splitting is done via `ctrl-k up/down/etc.`
* task terminals are "split" into regular terminals, and also not
persisted (same as currently in the terminal)
Seems ok for the initial version, we can revisit and polish things
later.
Release Notes:
- Added the ability to split the terminal panel
See ["mtime comparison considered
harmful"](https://apenwarr.ca/log/20181113) for details of why
comparators other than equality/inequality should not be used with
mtime.
Release Notes:

Motivation for this is to make things more understandable while figuring
out #20775.
This is intended to be a refactoring that does not affect behavior, but
there are a few tricky spots:
* Previously `File.mtime()` (now `File.disk_state().mtime()`) would
return last known modification time for deleted files. Looking at uses,
I believe this will not affect anything. If there are behavior changes
here I believe they would be improvements.
* `BufferEvent::DirtyChanged` is now only emitted if dirtiness actually
changed, rather than if it may have changed. This should only be an
efficiency improvement.

* `has_conflict` will now return true if the file has been deleted on
disk. This is for treating multi-buffers as conflicted, and also
blocks auto-save.
* `has_deleted_file` is added so that the single-file buffer save can
specifically mention the delete conflict. This does not yet handle
discard (#20745).
Closes#9101Closes#9568Closes#20462
Release Notes:
- Improved handling of externally deleted files: auto-save will be
disabled, multibuffers will treat this as a save conflict, and single
buffers will ask for restore confirmation.

Certain files like Rust stdlib ones can be opened by cmd-clicking on
terminal, editor contents, etc.
Those files will not belong to the current worktree, so a fake worktree,
with a single file, invisible (i.e. its dir(s) will not be shown in the
UI such as project panel), will be created on the file opening.
When the file is closed, the worktree is closed and removed along the
way, so those worktrees are considered ephemeral and their ids are not
stored in the database.
This causes issues on reopening such files when they are closed.
The PR makes Zed to fall back to opening the file by abs path when it's
not in the project metadata, but has the abs path stored in history or
in the opened items DB data.
Release Notes:
- Handle external worktree entries [re]open better
This PR makes it so that when we apply changes within a branch
buffer—currently just the edits buffer—we save the underlying buffer.
This also fixes an issue where new files created via edits were not
properly flushed to disk.

Prototypes a way to display new entities in the outline panel, making it
less outline.
The design is not final and might be adjusted, but the workflow seems to
be solid enough to keep and iron it out.
* Now, when any project search buffer is activated (multi buffer mode),
or buffer search is open (singleton buffer mode, but is available for
search usages multi buffer too — in that case buffer search overrides
multi buffer's contents display), outline panel displays all search
matches instead of the outline items.
Outline items are not displayed at all during those cases, unless the
buffer search is closed, or a new buffer gets opened, of an active
buffer search matches zero items.
https://github.com/user-attachments/assets/4a3e4faa-7f75-4522-96bb-3761872c753a
* For the multi buffer mode, search matches are grouped under
directories and files, same as outline items

* For buffer search , search matches are displayed one under another

For both cases, the entire match line is taken and rendered, with the
hover tooltip showing the line number.
So far it does not look very bad, but I am certain there are bad cases
with long lines and bad indents where it looks not optimal — this part
most probably will be redesigned after some trial.
Or, maybe, it's ok to leave the current state if the horizontal
scrollbar is added?
Clicking the item navigates to the item's position in the editor.
Search item lines are also possible to filter with the outline panel's
filter input.
* Inline panel is now possible to "pin" to track a currently active
editor, to display outlines/search results for that editor even if
another item is activated afterwards:

This is useful in combination with project search results display: now
it's possible to leave the search results pinned in the outline panel
and jump to every search result and back.
If the item the panel was pinned to gets closed, the panel gets back to
its regular state, showing outlines/search results for a currently
active editor.
Release Notes:
- Added a way to display buffer/project search entries in the outline
panel
This fixes a weird bug:
1. Use `/workflow` in assistant
2. Have it generate a step that modifies a file
3. Either (a) select the step in the assistant and have it auto-insert
newlines (b) select "Transform" to have the step applied
4. Close the modified file in the editor ("Discard")
5. Re-open the file
6. BUG: the changes made by assistant are still there!
The reason for the bug is that the assistant keeps references to buffers
and they're not closed/reloaded when closed/reopened.
To fix the bug we now rollback the applied workflow steps when
discarding a buffer.
(This does *not* yet fix the issue where a workflow step inserts a new
buffer into the project/worktree that does not show up on the file
system yet but in `/file` and hangs around until Zed is closed.)

This PR opens workflow step editors as preview tabs and closes them upon
exiting the step if they are still in preview mode and they weren't
already open before entering the step.
Making this work was tricky, because we often edit the buffer as part of
displaying the workflow step suggestions to create empty lines where we
can generate. We undo these edits if the transformation is not applied,
but they were causing the preview to be dismissed.
After trying a few approaches, I decided to give workspace `Item`s a
`preserve_preview` method that defaults to false. When the workspace
sees an edit event for the item, it checks if the item wants to preserve
its preview. For buffers, after editing, you can call `refresh_preview`,
which sets a preview version to the current version of the buffer. Any
edits after this version will cause preview to not be preserved.
One final issue is with async auto-indent. To ensure these async edits
don't dismiss the preview, I automatically refresh the preview version
if preview was preserved prior to performing the auto-indent. The
assumption is that these are edits created by other edits, and if we
didn't want to dismiss the preview with the originating edits, then the
auto-indent edits shouldn't dismiss it either.

Previously, we've only marked restored buffers as dirty. This PR changes
that behavior in case the buffer has been associated with a file and
that file has changed on disk since the last time Zed stored its
contents.
Example timeline:
1. User edits file in Zed, buffer is dirty
2. User quites Zed with `cmd-q`
3. User changes file on disk: `echo foobar >> file.txt` or `git checkout
file.txt`
4. User starts Zed
5. File/buffer are now marked as having a conflict (yellow icon)
Release Notes:
- Unsaved files that are restored when Zed starts are now marked as
having a conflict if they have been changed on disk since the last time
they were stored.
Demo:
https://github.com/user-attachments/assets/6098b485-b325-49b7-b694-fd2fc60cce64
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
This adds the ability for Zed to restore unsaved buffers on restart. The
user is no longer prompted to save/discard/cancel when trying to close a
Zed window with dirty buffers in it. Instead those dirty buffers are
stored and restored on restart.
It does this by saving the contents of dirty buffers to the internal
SQLite database in which Zed stores other data too. On restart, if there
are dirty buffers in the database, they are restored.
On certain events (buffer changed, file saved, ...) Zed will serialize
these buffers, throttled to a 100ms, so that we don't overload the
machine by saving on every keystroke. When Zed quits, it waits until all
the buffers are serialized.
### Current limitations
- It does not persist undo-history (right now we don't persist/restore
undo-history regardless of dirty buffers or not)
- It does not restore buffers in windows without projects/worktrees.
Example: if you open a new window with `cmd-shift-n` and type something
in a buffer, this will _not_ be stored and you will be asked whether to
save/discard on quit. In the future, we want to fix this by also
restoring windows without projects/worktrees.
### Demo
https://github.com/user-attachments/assets/45c63237-8848-471f-8575-ac05496bba19
### Related tickets
I'm unsure about closing them, without also fixing the 2nd limitation:
restoring of worktree-less windows. So let's wait until that.
- https://github.com/zed-industries/zed/issues/4985
- https://github.com/zed-industries/zed/issues/4683
### Note on performance
- Serializing editing buffer (asynchronously on background thread) with
500k lines takes ~200ms on M3 Max. That's an extreme case and that
performance seems acceptable.
Release Notes:
- Added automatic restoring of unsaved buffers. Zed can now be closed
even if there are unsaved changes in buffers. One current limitation is
that this only works when having projects open, not single files or
empty windows with unsaved buffers. The feature can be turned off by
setting `{"session": {"restore_unsaved_buffers": false}}`.

This is a ~small~ pure refactor that's a step toward SSH remoting. I've
extracted the Project's buffer state management into a smaller, separate
struct called `BufferStore`, currently in the same crate. I did this as
a separate PR to reduce conflicts between main and `remoting-over-ssh`.
The idea is to make use of this struct (and other smaller structs that
make up `Project`) in a dedicated, simpler `HeadlessProject` type that
we will use in the SSH server to model the remote end of a project. With
this approach, as we develop the headless project, we can avoid adding
more conditional logic to `Project` itself (which is already very
complex), and actually make `Project` a bit smaller by extracting out
helper objects.
Release Notes:
- N/A
Previously replace_all amounted to what could be achieved by repeatedly
mashing "Replace" button, which had a bunch of overhead related to
buffer state syncing. This commit gets rid of the automated button
mashing, processing all of the replacements in one go.
Fixes#13455
Release Notes:
- Improved performance of "replace all" in buffer search and project
search
This changes the breadcrumb header from "untitled" to "Last 1000 lines
in <location of log file>".
Reason is that it's been incredibly frustrating not seeing the location
of the log file there and not seeing that it's actually a truncated
version of the logs.
This is one remedy for that.
Other options considered:
1. Opening the actual log file. Turns out that is huge. On Linux right
now it's 5 megabyte after 5 minutes.
2. Opening the file and adding it on the buffer. That is tricky and
weird, because you have to modify the underlying buffer and set the
file, after having to add it to the workspace and getting its entry,
etc.
3. Setting a `display_file_path` on Buffer. That would require also
adding it on `BufferSnapshot` and then threading that through so that it
gets returned by the multi-buffer and then in the editor. And ultimately
this here is a "view concern", so we thought we just add it as such.
So yes, not the best change possible, but it's not that invasive and
makes it clear that it's a view-only concern.
