Buffers carry several pieces of state besides their text: syntax tree,
diagnostics, git diff, and file data. Previously, the buffer maintained
a separate integer version number for each of these four pieces of
state, incrementing it every time that piece of state is updated. This
is used by MultiBuffers to detect when they need to update excerpts.
Previously, for a given buffer, these four version numbers were stored
on the buffer itself, on every snapshot of the buffer, in any
multi-buffer that referenced that buffer, **and** on snapshots of that
multi-buffer. But the only use for the version numbers was reduced down
to a single boolean predicate: whether or not the buffer's state has
changed.
In this PR, I've combined those 4 version numbers into one. I've called
it `non_text_state_update_count` because it tracks all state updates
outside of the text itself. This removes a bunch of unnecessary code,
and reduces the size of buffer snapshots and multi-buffer snapshots.
Release Notes:
- N/A
This was due to a bug in the `MultiBufferSnapshot::excerpts_in_ranges`
method. As part of this, I took the chance to rewrite that logic and
simplify it a bit.

## TODO
### Lifecycle
* [x] Launch kernels on demand
* [x] Wait for kernel to be started
* [x] Request Kernel info on start
* [x] Show in progress indicator
* [ ] Allow picking kernel (it defaults to first matching language name)
* [ ] Menu for interrupting and shutting down the kernel
* [ ] Drop running kernels once editor is dropped
### Media Outputs
* [x] Render text and tracebacks with ANSI color handling
* [x] Render markdown as text
* [x] Render PNG and JPEG images using an explicit height based on
line-height
* ~~Render SVG~~ -- not happening for this PR due to lack of text in SVG
support
* [ ] Process `update_display_data` message and related `display_id`
* [x] Process `page` data from payloads as outputs
* [ ] Render markdown as, well, rendered markdown -- Note: unsure if we
can get line heights here
### Document
* [x] Select code and run
* [x] Run current line
* [x] Clear previous overlapping runs
* [ ] Support running markdown code blocks
* [ ] Action to export session as notebook or output files
* [ ] Action to clear all outputs
* [ ] Delete outputs when lines are deleted
## Other missing features
The following is a list of missing functionality or expectations that
are out of scope for this PR.
### Python Environments
Detecting python environments should probably be done in a separate PR
in tandem with how they're used with LSP. Users likely want to pick an
environment for their project, whether a virtualenv, conda env, pyenv,
poetry backed virtualenv, or the system. Related issues:
* https://github.com/zed-industries/zed/issues/7646
* https://github.com/zed-industries/zed/issues/7808
* https://github.com/zed-industries/zed/issues/7296
### LSP Integration
* Submit `complete_request` messages for completions to interleave
interactive variables with LSP
* LSP for IPython semantics (`%%timeit`, `!ls`, `get_ipython`, etc.)
## Future release notes
- Run code in any editor, whether it's a script or a markdown document

Indent guides can be configured per language, meaning that in a multi
buffer we can get excerpts where indent guides should be
disabled/enabled/styled differently than other excerpts.
Imagine the following scenario, i have indent guides disabled in my
settings, but want to enable them for JS and Python. I also want to use
a different line width for python files. Something like this is now
supported:
<img width="445" alt="image"
src="https://github.com/zed-industries/zed/assets/53836821/0c91411c-145c-4210-a883-4c469d5cb828">
And the relevant settings for the example above:
```json
"indent_guides": {
"enabled": false
},
"languages": {
"JavaScript": {
"indent_guides": {
"enabled": true
}
},
"Python": {
"indent_guides": {
"enabled": true,
"line_width": 5
}
}
}
```
Release Notes:
- Respect language specific settings when showing indent guides in a
multibuffer
- Fixes an issue where indent guide specific settings were not
recognized when specified in local settings
Release Notes:
- Improved expand excerpt indicators to allow unidirectional expansion.
Also added the `editor::ExpandExcerptsUp` and
`editor::ExpandExcerptsDown` actions, which can both take a `lines`
parameter. Also added a `expand_excerpt_lines` setting which controls
the default number of lines that the indicators and actions use.

From now on, only top-level captures are treated as runnable tags and
the rest is appended to task context as custom environmental variables
(unless the name is prefixed with _, in which case the capture is
ignored). This is most likely gonna help with Pest-like test runners.

Added two new actions with the default keybindings
```
"cmd-'": "editor::ToggleHunkDiff",
"cmd-\"": "editor::ExpandAllHunkDiffs",
```
that allow to browse git hunk diffs in Zed:
https://github.com/zed-industries/zed/assets/2690773/9a8a7d10-ed06-4960-b4ee-fe28fc5c4768
The hunks are dynamic and alter on user folds and modifications, or
toggle hidden, if the modifications were not adjacent to the expanded
hunk.
Release Notes:
- Added `editor::ToggleHunkDiff` (`cmd-'`) and
`editor::ExpandAllHunkDiffs` (`cmd-"`) actions to browse git hunk diffs
in Zed
This PR adds an action to expand the excerpts lines of context in a
multibuffer.
Release Notes:
- Added an `editor::ExpandExcerpts` action (bound to `shift-enter` by
default), which can expand the excerpt the cursor is currently in by 3
lines. You can customize the number of lines by rebinding this action
like so:
```json5
// In your keybindings array...
{
"context": "Editor && mode == full",
"bindings": {
"shift-enter": ["editor::ExpandExcerpts", { "lines": 5 }],
}
}
```

This PR renames `language::Buffer::new` to `language::Buffer::local` and
simplifies its interface. Instead of taking a replica id (which should
always be 0 for the local case) and a `BufferId`, which was awkward and
verbose to construct, it simply takes text and a `cx`.
It uses the `cx` to derive a `BufferId` from the `EntityId` associated
with the `cx`, which should always be positive based on the following
analysis...
We convert the entity id to a u64 using this method on `EntityId`, which
is defined by macros in the `slotmap` crate:
```rust
pub fn as_ffi(self) -> u64 {
(u64::from(self.version.get()) << 32) | u64::from(self.idx)
}
```
If you look at the type of `version` in `KeyData`, it is non-zero:
```rust
#[derive(Clone, Copy, PartialEq, Eq, PartialOrd, Ord, Hash)]
pub struct KeyData {
idx: u32,
version: NonZeroU32,
}
```
This commit also adds `Context::reserve_model` and
`Context::insert_model` to determine a model's entity ID before it is
created, which we need in order to assign a `BufferId` in the background
when loading a buffer asynchronously.

This increases search context from 1 above, 2 below, to 2 above and 2
below, matching the Sublime Text search results.
Release Notes:
- Increased search result context from 3 lines to 4 lines
Once we enable extensions to customize the labels of completions and
symbols, this new structure will allow this to be done with a single
WASM call, instead of one WASM call per completion / symbol.

Three changes: two of which are changing `while let` construct to `if
let` as they unconditionally broke and one of which was removing a loop
in the `start_default_prettier` as it unconditionally broke in the
control flow for match installation task: the diff for this is larger
than needed as removing the loop changed a lot of indentation for
`rustfmt`.
We were seeing panics due to callers assuming they had valid
excerpt_ids, but that cannot easily be guaranteed across await points as
anyone may remove an excerpt.
Release Notes:
- Fixed a panic when hovering in a multibuffer
This PR moves the Clippy configuration up to the workspace level.
We're using the [`lints`
table](https://doc.rust-lang.org/cargo/reference/workspaces.html#the-lints-table)
to configure the Clippy ruleset in the workspace's `Cargo.toml`.
Each crate in the workspace now has the following in their own
`Cargo.toml` to inherit the lints from the workspace:
```toml
[lints]
workspace = true
```
This allows for configuring rust-analyzer to show Clippy lints in the
editor by using the following configuration in your Zed `settings.json`:
```json
{
"lsp": {
"rust-analyzer": {
"initialization_options": {
"check": {
"command": "clippy"
}
}
}
}
```

This PR adds a new `argument` vim text object, inspired by
[targets.vim](https://github.com/wellle/targets.vim).
As it's the first vim text object to use the syntax tree, it needed to
operate on the `Buffer` level, not the `MultiBuffer` level, then map the
buffer coordinates to `DisplayPoint` as necessary.
This required two main changes:
1. `innermost_enclosing_bracket_ranges` and `enclosing_bracket_ranges`
were moved into `Buffer`. The `MultiBuffer` implementations were updated
to map to/from these.
2. `MultiBuffer::excerpt_containing` was made public, returning a new
`MultiBufferExcerpt` type that contains a reference to the excerpt and
methods for mapping to/from `Buffer` and `MultiBuffer` offsets and
ranges.
Release Notes:
- Added new `argument` vim text object, inspired by
[targets.vim](https://github.com/wellle/targets.vim).
Hopefully this makes it a bit easier for new contributors to dive into
the codebase :)
Release Notes:
- Improved documentation for many core editor types

This PR implements support for displaying diagnostics in the scrollbar,
similar to what is already done for search results, symbols, git diff,
...
For example, changing a field name (`text`) without changing the
references looks like this in `buffer.rs` (note the red lines in the
scrollbar):
As you can see, the errors, warnings, ... are displayed in the scroll
bar, which helps to identify possible problems with the current file.
Relevant issues: #4866, #6819
Release Notes:
- Added diagnostic indicators to the scrollbar
Adds a "markdown: open preview" action to open a markdown preview.
https://github.com/zed-industries/zed/assets/18583882/6fd7f009-53f7-4f98-84ea-7dd3f0dd11bf
This PR extends the work done in `crates/rich_text` to render markdown
to also support:
- Variable heading sizes
- Markdown tables
- Code blocks
- Block quotes
## Release Notes
- Added `Markdown: Open preview` action to partially close
([#6789](https://github.com/zed-industries/zed/issues/6789)).
## Known issues that will not be included in this PR
- Images.
- Nested block quotes.
- Footnote Reference.
- Headers highlighting.
- Inline code highlighting (this will need to be implemented in
`rich_text`)
- Checkboxes (`- [ ]` and `- [x]`)
- Syntax highlighting in code blocks.
- Markdown table text alignment.
- Inner markdown URL clicks
Release Notes:
- Added bash syntax highlighting to `.env` files.
- Added a `private_files` setting for configuring which files should be
considered to contain environment variables or other sensitive
information.
- Added a `redact_private_values` setting to add or remove censor bars
over variable values in files matching the `private_files` patterns.
-(internal) added a new `redactions.scm` query to our language support,
allowing different config file formats to indicate where environment
variable values can be identified in the syntax tree, added this query
to `bash`, `json`, `toml`, and `yaml` files.
