Closes https://github.com/zed-industries/zed/issues/4925https://github.com/user-attachments/assets/e7b87375-893f-41ae-a2d9-d501499e40d1
Allows to fold any buffer inside multi buffers, either by clicking the
chevron icon on the header, or by using
`editor::Fold`/`editor::UnfoldLines`/`editor::ToggleFold`/`editor::FoldAll`
and `editor::UnfoldAll` actions inside the multi buffer (those were noop
there before).
Every fold has a fake line inside it, so it's possible to navigate into
that via the keyboard and unfold it with the corresponding editor
action.
The state is synchronized with the outline panel state: any fold inside
multi buffer folds the corresponding file entry; any file entry fold
inside the outline panel folds the corresponding buffer inside the multi
buffer, any directory fold inside the outline panel folds the
corresponding buffers inside the multi buffer for each nested file entry
in the panel.
Release Notes:
- Added a possibility to fold buffers inside multi buffers

Closes https://github.com/zed-industries/zed/issues/8534
Supersedes https://github.com/zed-industries/zed/pull/16349
Potential concerns:
* we do not follow up to the `/` when looking for `.editorconfig`, only
up to the worktree root.
Seems fine for most of the cases, and the rest should be solved
generically later, as the same issue exists for settings.json
* `fn language` in `AllLanguageSettings` is very hot, called very
frequently during rendering. We accumulate and parse all `.editorconfig`
file contents beforehand, but have to go over globs and match these
against the path given + merge the properties still.
This does not seem to be very bad, but needs more testing and
potentially some extra caching.
Release Notes:
- Added .editorconfig support

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
Builds on top of existing work from #2249, but here's a showcase:

TODO:
- [x] handle line wrapping
- [x] implement handling in multibuffer (crashes currently)
- [x] add configuration option
- [x] new theme properties? What colors to use?
- [x] Possibly support indents with different colors or background
colors
- [x] investigate edge cases (e.g. indent guides and folds continue on
empty lines even if the next indent is different)
- [x] add more tests (also test `find_active_indent_index`)
- [x] docs (will do in a follow up PR)
- [x] benchmark performance impact
Release Notes:
- Added indent guides
