Thorsten BallandAntonio 42ac9880c6 Detect and possibly use user-installed gopls / zls language servers (#8188)
After a lot of back-and-forth, this is a small attempt to implement
solutions (1) and (3) in
https://github.com/zed-industries/zed/issues/7902. The goal is to have a
minimal change that helps users get started with Zed, until we have
extensions ready.

Release Notes:

- Added detection of user-installed `gopls` to Go language server
adapter. If a user has `gopls` in `$PATH` when opening a worktree, it
will be used.
- Added detection of user-installed `zls` to Zig language server
adapter. If a user has `zls` in `$PATH` when opening a worktree, it will
be used.

Example:

I don't have `go` installed globally, but I do have `gopls`:

```
~ $ which go
go not found
~ $ which gopls
/Users/thorstenball/code/go/bin/gopls
```

But I do have `go` in a project's directory:

```
~/tmp/go-testing φ which go
/Users/thorstenball/.local/share/mise/installs/go/1.21.5/go/bin/go
~/tmp/go-testing φ which gopls
/Users/thorstenball/code/go/bin/gopls
```

With current Zed when I run `zed ~/tmp/go-testing`, I'd get the dreaded
error:

But with the changes in this PR, it works:

```
[2024-02-23T11:14:42+01:00 INFO  language::language_registry] starting language server "gopls", path: "/Users/thorstenball/tmp/go-testing", id: 1

Marshall Bowers 0de8672044 Add SystemClock (#8239)
This PR adds a `SystemClock` trait for abstracting away the system
clock.

This allows us to swap out the real system clock with a
`FakeSystemClock` in the tests, thus allowing the fake passage of time.

We're using this in `Telemetry` to better mock the clock for testing
purposes.

Joseph T. Lyons 38c3a93f0c Add action to open release notes locally (#8173)
Fixes: https://github.com/zed-industries/zed/issues/5019

zed.dev PR: https://github.com/zed-industries/zed.dev/pull/562

I've been wanting to be able to open release notes in Zed for awhile,
but was blocked on having a rendered Markdown view. Now that that is
mostly there, I think we can add this. I have not removed the `auto
update: view release notes` action, since the Markdown render view
doesn't support displaying media yet. I've opted to just add a new
action: `auto update: view release notes locally`. I'd imagine that in
the future, once the rendered view supports media, we could remove `view
release notes` and `view release notes locally` could replace it.
Clicking the toast that normally is presented on update
(https://github.com/zed-industries/zed/issues/7597) would show the notes
locally.

The action works for stable and preview as expected; for dev and
nightly, it just pulls the latest stable, for testing purposes.

I changed the way the markdown rendered view works by allowing a tab
description to be passed in.

For files that have a name, it will use `Preview <name>`:

src="https://github.com/zed-industries/zed/assets/19867440/a0ef34e5-bd6d-4b0c-a684-9b09d350aec4">

For untitled files, it defaults back to `Markdown preview`:

Release Notes:

- Added a `zed: view release notes locally` action
([#5019](https://github.com/zed-industries/zed/issues/5019)).

other code, see
https://github.com/zed-industries/zed/actions/runs/7980269779/job/21789529800

Also, due to `#!/usr/bin/env bash` shebang in the `script/clippy`, it
starts in Windows CI with `shell: C:\Program Files\Git\bin\bash.EXE
-euxo pipefail {0}`

gmorenz 8f5d7db875 First pass at making a linux keymap (#8082)
Undoubtedly not perfect, but this should be something we can work off
of.

Note that matching keybindings with ctrl in them is currently broken on
linux (or at least x11). This keymap might just manage to be less useful
than using the macos one on linux until that is fixed... the proximate
cause of this is that the `key` field of the `Keystroke` struct looks
like `"\u{e}"` instead of `"n"` when `ctrl-n` is pressed.

f17d0b5729 Add static Runnables (#8009)
Part of #7108

This PR includes just the static runnables part. We went with **not**
having a dedicated panel for runnables.
This is just a 1st PR out of N, as we want to start exploring the
dynamic runnables front. Still, all that work is going to happen once
this gets merged.

Release Notes:

- Added initial, static Runnables support to Zed. Such runnables are defined in
`runnables.json` file (accessible via `zed: open runnables` action) and
they can be spawned with `runnables: spawn` action.

claytonrcarter cd4d2f7900 Add Prettier support for Vue, Markdown and PHP (#7904)
Current prettier support w/i Zed leaves out a few languages that are
officially supported by prettier. In particular, Vue and Markdown are
supported by the core prettier project, and PHP is supported via an
official plugin. I didn't see any open issues for this, but I have been
wondering for months why `"formatter": "prettier"` wasn't working on my
PHP files. Now that Zed is open source, I was able to find out why, and
fix it. 😄

I have been using this with PHP files daily for a week+ now, and I have
also used it successfully with Vue and Markdown files, though not as
extensively. I looked around and did not see any tests for specific
prettier language integrations, but if I missed them please let me know
and I'll add some tests.

**Notes**
- I did not add support for Ruby (which has an official prettier plugin)
because it seems to require some external dependencies (notably, Rudy
and some Gems). When those are present on the system and `$PATH`,
prettier will will work just fine on Ruby files if the plugin is set up
similar to how the PHP plugin is set up (I tried it), and I can add that
in here, if desired. The PHP plugin is pure JS (as I recall) and doesn't
have this issue.
- I did *not* add support for languages that have "community" plugins,
though I do note that Zed already ships with prettier support for svelte
enabled, which – if I understand correctly – is powered by a community
plugin. If desired, I could look at adding support/configuration to
enable prettier support for things like elm, erb, glsl, bash, toml.
Bash, in particular, *I* would find useful. 😄

Release Notes:

- Added prettier support for Vue, Markdown and PHP

Thorsten Ball b47aff4c14 go: enable completions with placeholders by default (#7780)
This fixes #7523 by enabling completions with placeholders by default.

This setting controls whether gopls sends back snippets with
placeholders. According to the documentation
(https://github.com/golang/tools/blob/master/gopls/doc/settings.md#useplaceholders-bool)
this only controls whether "placeholders for function parameters or
struct fields" are sent in completion responses.

In practice, though, this seems to also control whether any snippets
with *any* placeholders are being sent back.

Example: for the given Go code

    err := myFunction()
    i^

With the cursor being at `^`, this setting controls whether `gopls`
sends back statement snippets such as `if err != nil { return ... }`
with the `...` being dynamically matched to the return value of the
function.

So I think this setting controls far more than just function params and
struct fields. And since we *do* support placeholders in snippets, I
think this provides a better default experience.

Release Notes:

- Improved default Go experience by enabling snippets-with-placeholders
when initializing `gopls`.

https://github.com/zed-industries/zed/issues/4471#issuecomment-1936008584

Improves gopls error logging to actually see what is wrong with the
output we failed to match against the version regex.

Antonio Scandurra 0cebf68306 Introduce a new ToggleGraphicsProfiler command (#7607)
On macOS, this will enable or disable the Metal HUD at runtime. Note
that this only works when Zed is bundled because it requires to set the
`MetalHudEnabled` key in the Info.plist.

Release Notes:

- Added a new `ToggleGraphicsProfiler` command that can be used as an
action (or via the `Help -> Toggle Graphics Profiler` menu) to
investigate graphics performance.

Marshall Bowers bde509fa74 Expose Python docstrings for syntax highlighting (#7587)
This PR extends our Tree-sitter highlights for Python to allow
highlighting docstrings differently from other strings.

Docstrings in Python will now use `string.doc` instead of just `string`,
which will allow for them to be styled independently of other strings.
If no `string.doc` is present in the theme, then it will fall back to
using the `string` styles.

This is slightly different than the approach I took in #7585 in that we
are still treating docstrings as strings by default (which appears to be
the more common behavior), but allowing theme authors to hook in and
style them separately, if desired.

Release Notes:

- Added ability add custom styles for Python docstrings using
`string.doc`
([#7346](https://github.com/zed-industries/zed/issues/7346)).

Daniel Banck 9e538e7916 Support Terraform Variable Definitions as separate language (#7524)
With https://github.com/zed-industries/zed/pull/6882 basic syntax
highlighting support for Terraform has arrived in Zed. To fully support
all features of the language server (when it lands), it's necessary to
handle `*.tfvars` slightly differently.

TL;DR: [terraform-ls](https://github.com/hashicorp/terraform-ls) expects
`terraform` as language id for `*.tf` files and `terraform-vars` as
language id for `*.tfvars` files because the allowed configuration
inside the files is different. Duplicating the Terraform language
configuration was the only way I could see to achieve this.

---

In the
[LSP](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#textDocumentItem),
text documents have a language identifier to identify a document on the
server side to avoid reinterpreting the file extension.

The Terraform language server currently uses two different language
identifiers:
* `terraform` - for `*.tf` files
* `terraform-vars` - for `*.tfvars` files

Both file types contain HCL and can be highlighted using the same
grammar and tree-sitter configuration files. The difference in the file
content is that `*.tfvars` files only allow top-level attributes and no
blocks. [_So you could argue that `*.tfvars` can use a stripped down
version of the grammar_]. To set the right context (which affects
completion, hover, validation...) for each file, we need to send a
different language id.

The only way I could see to achieve this with the current architecture
was to copy the Terraform language configuration with a different `name`
and different `path_suffixes`. Everything else is the same.

A Terraform LSP adapter implementation would then map the language
configurations to their specific language ids:

```rust
fn language_ids(&self) -> HashMap<String, String> {
    HashMap::from_iter([
        ("Terraform".into(), "terraform".into()),
        ("Terraform Vars".into(), "terraform-vars".into()),
    ])
}
```

I think it might be helpful in the future to have another way to map
file extensions to specific language ids without having to create a new
language configuration.
