This PR reverts the addition of the YAML icon, as it doesn't look good
at the moment:

This reverts commit a853a80634149ad5d069c48c4a0ece0bd584b5b1.

This adds four new actions:

- `editor::MoveUpByLines`
- `editor::MoveDownByLines`
- `editor::SelectUpByLines`
- `editor::SelectDownByLines`

They all take a count by which to move the cursor up and down.
(Requested by Adam here:
https://twitter.com/adamwathan/status/1753017094248018302)


Example `keymap.json` entries:

```json
{
  "context": "Editor",
  "bindings": [
    "alt-up":         [ "editor::MoveUpByLines",     { "lines": 3 } ],
    "alt-down":       [ "editor::MoveDownByLines",   { "lines": 3 } ],
    "alt-shift-up":   [ "editor::SelectUpByLines",   { "lines": 3 } ],
    "alt-shift-down": [ "editor::SelectDownByLines", { "lines": 3 } ]
  ]
}
```

They are *not* bound by default, so as to not conflict with the
`alt-up/down` bindings that already exist.

Release Notes:

- Added four new actions: `editor::MoveUpByLines`,
`editor::MoveDownByLines`, `editor::SelectUpByLines`,
`editor::SelectDownByLines` that can take a line count configuration and
move the cursor up by the count.

I ran into this a lot with Go code: the documentation would be empty so
we'd display a big box with nothing in it.

I think it's better if we only display the box if we have documentation.

Release Notes:

- Fixed documentation box in showing up when using auto-complete even if
documentation was empty.

Fixes #7236.

The reason why the code was not displayed correctly is due to missing
background color for the inline code block.

alt="Screenshot showing that inline code blocks are now highlighted in
Markdown preview">



Release Notes:

- Fixed inline code block not shown in markdown preview
([#7236](https://github.com/zed-industries/zed/issues/7236)).

This changes the highlighting of Go code to make it more similar to how
we highlight Rust

* normal variables have the normal color, vs. being highlighted. This
really stuck out.
* brackets are properly highlighted

It also brings it closer to Neovim's tree-sitter highlighting by
changing how struct fields are highlighted.



Release Notes:

- Improved highlighting of Go code by tuning highlighting of variables,
brackets, and struct fields.

## Before & After

The way Rust generics works, having a generic argument puts the burden of codegen on the crate that instantiates a generic function, which in our case is an editor.

This changes the Go `outline.scm` queries a bit so that we don't have
these stray whitespaces floating around. I'm sure there's more
improvements possible, but for now I think this makes it look less
wrong.

Release Notes:

- Improved outline and breadcrumbs for Go code.

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):

![image](https://github.com/zed-industries/zed/assets/53836821/c46f0d55-32e3-4334-8ad7-66d1578d5725)

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

This reverts commit 020c38a8916c063cba36c2c88a69b5e287269d5a because it
leads to glitches when selecting text.

After this change we'll be able to push a tag to github to deploy to
collab.

The advantages of this are that there's no longer a separate step to
first
build the image, and then deploy it.

In the future I'd like to make this happen more automatically (maybe as
part of
bump nightly).

This will introduce an extra conditional but saves us from doing a bunch
of math in the simple case of drawing simple rectangles that aren't
rounded or don't have borders.

This pull request implements support for the [Erlang
Language](https://erlang.org/).

**It adds:**

* [tree-sitter-erlang](https://github.com/WhatsApp/tree-sitter-erlang)
grammar
highlights (Licensed under Apache-2 from WhatsApp which is compatible
with Zed licensing model), folds and indents
* Erlang file icon based on the [official
one](https://www.erlang.org/doc/erlang-logo.png)
* [erlang_ls](https://github.com/erlang-ls/erlang_ls) support

Fixes https://github.com/zed-industries/zed/issues/4939, possibly a
duplicate of https://github.com/zed-industries/zed/pull/7085 with more
features. Suppose @wingyplus wants to join efforts here.

**To complete (out of scope for this PR):**

* Support for the ELP language server from WhatsApp. CC @robertoaloi
* Better indentation handling, need something like
`indentNextLinePattern` in VS Code

Previously we would run these loops indefinitely when a language server
closed its stdout/stderr and the `read_until` returned `0` bytes read.

Easy to reproduce: start Zed with LSP attached, `kill -9` the LSP, see
logs accumulate.

Release Notes:

- Fix high CPU usage when a language server crashes (or closes its
stdout/stderr on purpose).

This is a follow-up to #7141 and fixes the focus-switching to docks in
case they haven't been focused before.

We ran into issues when trying to focus a dock, that hasn't been focused
in the app's lifecycle: focus would only flip after the next re-render
(which could be triggered by moving the mouse, for example)

This changes the approach and uses the one we have for `toggle focus`
actions.
