This fixes a panic I randomly ran into whilst mistyping in the command
palette: I accidentally ran `pane: swap item right`in a state where no
items were opened in my active pane. We were checking for `index + 1 ==
self.items.len()` there when it really should be `>=`, as otherwise in
the case of no items this panics.
This PR fixes the bug, adds a test for both the panic as well as the
actions themselves (they were untested previously). Lastly (and mostly),
this also cleans up a bit around existing actions to update them with
how we generally handle actions now.
Release Notes:
- Fixed a panic that could occur with the `pane: swap item right`
action.
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.

- N/A
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#18565
I could use some advice on the color palette / theming. A couple
options:
1. The `drop_target_background` color could be used for the border if we
didn't use it for the background of the tab. In VSCode, the background
color of tabs doesn't change as you're dragging, there's just a border
between tabs. My only concern with this option is that the current
`drop_target_background` color is a bit subtle when used for a small
area like a border.
2. Another option could be to add a `drop_target_border` theme color,
but I don't know how much complexity this adds to implementation
(presumably all existing themes would need to be updated?).

1. Extension loaded events are now condensed into a single event with a
Vec of (extension_id, extension_version) called id_and_versions.
2. Editor Saved & AutoSaved are merged into a singular event with a type
field that is either "manual" or "autosave”.
3. Editor Edited event will only fire once every 10 minutes now.
4. Editor Closed event is fired when an editor item (tab) is removed
from a pane

Follow up to #31836
After enabling rounding in the Taffy layout engine, we frequently run
into cases where the bounds produced by Taffy and ours slightly differ
after 5 or more decimal places. This leads to cases where containers
become scrollable for less than 0.0000x Pixels. In case this happens for
e.g. hover popovers, we render a scrollbar due to the container being
technically scrollable, even though the scroll amount here will in
practice never be visible.
This change fixes this by rounding the `scroll_max` by which we clamp
the current scroll position to two decimal places. We don't benefit from
the additional floating point precision here at all and it stops such
containers from becoming scrollable altogether. Furthermore, we now
store the `scroll_max` instead of the `padded_content_size` as the
former gives a much better idea on whether the corresponding container
is scrollable or not.

Release Notes:
- Fixed an issue where scrollbars would appear in containers where no
scrolling was possible.
This is following feedback from folks that were searching the "close
others" action, available in the tab's context menu, and not finding it
because it was actually named "close inactive", which was confusing. So,
this PR makes sure the tab's menu item and the action have consistent
naming.
Release Notes:
- Rename "CloseInactiveItems" action to "CloseOtherItems" for naming
consistency.

- Switches to the debounce task pattern for diagnostic summary
computations, which most importantly lets us do them only once when a
large number of DiagnosticUpdated events are received at once.
- Makes workspace diagnostic requests not time out if a partial result
is received.
- Makes diagnostics from workspace diagnostic partial results get
merged.
There might be some related areas where we're not fully complying with
the LSP spec but they may be outside the scope of what this PR should
include.
Release Notes:
- Added support for streaming LSP workspace diagnostics.
- Fixed editor freeze from large LSP workspace diagnostic responses.
Closes#33445
Fixed the "Close others" context menu action to close tabs relative to
the right-clicked tab instead of the currently active tab. Previously,
when right-clicking on an inactive tab and selecting "Close others", it
would keep the active tab open rather than the right-clicked tab.
## Before/After
https://github.com/user-attachments/assets/d76854c3-c490-4a41-8166-309dec26ba8a
## Changes
- Modified `close_inactive_items()` method to accept an optional
`target_item_id` parameter
- Updated context menu handler to pass the right-clicked tab's ID as the
target
- Maintained backward compatibility by defaulting to active tab when no
target is specified
- Updated all existing call sites to pass `None` for the new parameter
Release Notes:
- Fixed: "Close others" context menu action now correctly keeps the
right-clicked tab open instead of the active tab
Closes #ISSUE
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.
Release Notes:
- N/A *or* Added/Fixed/Improved ...
* Add a "close item"-like binding to close the active dock, if present
Now, cmd/ctrl-w can be used close the focused dock before the Zed window
* Add defaults to MoveItem* actions to make it appear in the command
palette
Release Notes:
- N/A
Closes #ISSUE
Adds a right click context menu to table rows, refactoring the table API
to support more general row rendering in the process, and creating
actions for the couple of operations available in the context menu.
Additionally includes an only partially related change to the context
menu API, which makes it easier to have actions that are disabled based
on a boolean value.

## Summary
This PR improves the workaround introduced in #33335 that handles cases
where the pinned tab count exceeds the actual tab count during workspace
deserialization.
## Problem
The original workaround in #33335 successfully prevented the panic but
had two issues:
1. **Console spam**: The warning message was logged repeatedly because
`self.pinned_tab_count` wasn't updated to match the actual tab count
2. **Auto-pinning behavior**: New tabs up until you exceed the old safe
tab count were automatically pinned after the workaround was triggered.
## Solution
Updates the defensive code to set `self.pinned_tab_count = tab_count`
when the mismatch is detected, ensuring:
- The warning is only logged once when encountered.
- New tabs behave normally (aren't auto-pinned)
- The workspace remains in a consistent state
This is an immediate fix for the workaround. I'll attempt to open up a
follow-up PR when i get the chance that will address the root cause by
implementing serialization for empty untitled tabs, as discussed in
#33342.
Release Notes:
- N/A
After much investigation, I have not been able to track down what is
causing [this
panic](https://github.com/zed-industries/zed/issues/33342). I'm clamping
the value for now, because a bug is better than a crash. Hopefully
someone finds reproduction steps, and I will implement a proper fix.
Release Notes:
- N/A
Instead of a menagerie of macros for implementing `Action`, now there
are just two:
* `actions!(editor, [MoveLeft, MoveRight])`
* `#[derive(..., Action)]` with `#[action(namespace = editor)]`
In both contexts, `///` doc comments can be provided and will be used in
`JsonSchema`.
In both contexts, parameters can provided in `#[action(...)]`:
- `namespace = some_namespace` sets the namespace. In Zed this is
required.
- `name = "ActionName"` overrides the action's name. This must not
contain "::".
- `no_json` causes the `build` method to always error and
`action_json_schema` to return `None`
and allows actions not implement `serde::Serialize` and
`schemars::JsonSchema`.
- `no_register` skips registering the action. This is useful for
implementing the `Action` trait
while not supporting invocation by name or JSON deserialization.
- `deprecated_aliases = ["editor::SomeAction"]` specifies deprecated old
names for the action.
These action names should *not* correspond to any actions that are
registered. These old names
can then still be used to refer to invoke this action. In Zed, the
keymap JSON schema will
accept these old names and provide warnings.
- `deprecated = "Message about why this action is deprecation"`
specifies a deprecation message.
In Zed, the keymap JSON schema will cause this to be displayed as a
warning. This is a new feature.
Also makes the following changes since this seems like a good time to
make breaking changes:
* In `zed.rs` tests adds a test with an explicit list of namespaces. The
rationale for this is that there is otherwise no checking of `namespace
= ...` attributes.
* `Action::debug_name` renamed to `name_for_type`, since its only
difference with `name` was that it
* `Action::name` now returns `&'static str` instead of `&str` to match
the return of `name_for_type`. This makes the action trait more limited,
but the code was already assuming that `name_for_type` is the same as
`name`, and it requires `&'static`. So really this just makes the trait
harder to misuse.
* Various action reflection methods now use `&'static str` instead of
`SharedString`.

This was a regression with my recent fixes to pinned tabs. Dragging a
pinned tab left in the pinned region would still update the pinned tab
count, which would later cause an out-of-bounds later when it used that
value to index into a vec.
https://zed-industries.slack.com/archives/C04S6T1T7TQ/p1749220447796559
Release Notes:
- Fixed a panic caused by dragging a pinned item to the left in the
pinned region
Release Notes:
- Debugger Beta: `shift-escape` (`workspace::ToggleZoom`) now zooms the
entire debug panel; `alt-shift-escape` (`debugger::ToggleExpandItem`)
triggers the old behavior of zooming a specific item.
The optimization to not move a tab being pinned (when the destination
index is the same as its index) in
https://github.com/zed-industries/zed/pull/31871 caused a regression, as
we were no longer calling `cx.notify()` indirectly through `move_item`.
Thanks for catching this, @smitbarmase.
Release Notes:

Closes https://github.com/zed-industries/zed/issues/31870
Release Notes:
- Allowed opening 1 more item if `n` tabs are pinned, where `n` equals
`max_tabs` count.
- Fixed a bug where pinned tabs would eventually be closed out when
exceeding the `max_tabs` count.
- Fixed a bug where a tab could be lost when pinning a tab while at the
`max_tabs` count.
- Fixed a bug where pinning a tab when already at the `max_tabs` limit
could cause other tabs to be incorrectly closed.
This PR adds a comprehensive test that ensures that no item-closing
action will panic when no items are present. A test already existed
(`test_remove_active_empty `) that ensured `CloseActiveItem` didn't
panic, but the new test covers:
- `CloseActiveItem`
- `CloseInactiveItems`
- `CloseAllItems`
- `CloseCleanItems`
- `CloseItemsToTheRight`
- `CloseItemsToTheLeft`
I plan to do a bit more clean up in `pane.rs` and this feels like a good
thing to add before that.
Release Notes:
- N/A
