On Windows, `OsStr` must be a valid
[WTF-8](https://simonsapin.github.io/wtf-8/) sequence, and there are no
safety ways converting from bytes to OsStr in std. So I added
`PathExt::try_from_bytes` and use it in `sqlez`.
This PR adds support for loading user themes in Zed.
Themes are loaded from the `themes` directory under the Zed config:
`~/.config/zed/themes`. This directory should contain JSON files
containing a `ThemeFamilyContent`.
Here's an example of the general structure of a theme family file:
```jsonc
{
"name": "Vitesse",
"author": "Anthony Fu",
"themes": [
{
"name": "Vitesse Dark Soft",
"appearance": "dark",
"style": {
"border": "#252525",
// ...
}
}
]
}
```
Themes placed in this directory will be loaded and available in the
theme selector.
Release Notes:
- Added support for loading user themes from `~/.config/zed/themes`.
This PR adds undocumented functionality for loading custom language
plugins at runtime. I don't intend to expose the functionality to end
users yet, but this will allow the team to test the capability
internally.
### Implementation
There isn't much new code in Zed. Most of the work here is within
Tree-sitter, in PRs https://github.com/tree-sitter/tree-sitter/pull/1864
and https://github.com/tree-sitter/tree-sitter/pull/2840, which allow
Tree-sitter to load languages from WASM blobs. I've tested the
functionality in Tree-sitter's test suite and via its CLI, but having it
wired into Zed allows us to test the functionality more fully.
### Details
Now, on startup, Zed will look for subdirectories inside of
`~/Application Support/plugins`. These subdirectories are expected to
look similar to the per-language subdirectories in
[`crates/zed2/src/languages`](https://github.com/zed-industries/zed/tree/main/crates/zed2/src/languages),
except that they also contain a `.wasm` file for the parser itself.
I'll add more details here as I go.
New rustc messages look like
```
thread 'tests::test_history_items_vs_very_good_external_match' panicked at crates/file_finder/src/file_finder.rs:1902:13:
assertion `left == right` failed: Only one history item contains collab_ui, it should be present and others should be filtered out
left: 0
right: 1
```
now and we fail to parse that `13:` bit properly, fix that.
Still need to implement loading / listing.
I'd really be rather write operations to a database. Maybe we
should be auto-saving? Integrating with panes? I just did
the simple thing for now.
