Closes https://github.com/zed-industries/zed/issues/25413
As the issue points out well, themes do not need to alter any in-memory
state on load: that is done via settings file load.
Originally, it was introduced in
https://github.com/zed-industries/zed/pull/4064 and
https://github.com/zed-industries/zed/pull/24857 had restored that
behavior, which seems wrong to do.
Apart from removing that part, removes unnecessary methods and
emphasizes that in-memory state is the Buffer/UI size — no need to add
`Adjusted` there as the settings file presence is already enough.
Release Notes:
- Fixed theme selector resetting the buffer size
We've decided to go in a different direction on indicating the staged
status of hunks, so go back for now to a world where we don't display
staged and unstaged hunks differently outside the (still gated) project
diff editor.

This PR makes it so we don't log errors for missing themes or icon
themes until after the extensions have been loaded.
Currently, if you are using a theme that is defined in an extension it
is common to see one or more "theme not found" errors in the logs. This
is the result of us having to initialize the theme before the extensions
have actually finished loading.
This means that a theme that _may_ exist once extensions load is
considered non-existent before they have loaded.
To that end, we now wait until the extensions have loaded before we
start logging errors if we can't find the theme or icon theme.
Closes https://github.com/zed-industries/zed/issues/24539.
Release Notes:
- Reduced the number of "theme not found" and "icon theme not found"
errors in the logs for themes provided by extensions.
This PR updates the `ThemeRegistry` to return structured errors from the
`get` and `get_icon_theme` methods (which are used to retrieve themes
and icon themes, respectively).
We want to be able to carry the name of the theme that was not found as
state on the error, which is why we use a `Result` and not an `Option`.
However, we also want to be able to accurately identify when the error
case is "not found" so we can take appropriate action, based on the
circumstances.
By using a custom error type instead of an `anyhow::Error`, we get both.
There isn't any functional change in this PR. This just sets us up for
future improvements in this error.

.RData is a file that stores R objects.
Release Notes:
- Added file icon associations for `.rdata` and `.RData` files.

This PR adds the ability for icon themes to provide their own file
associations.
The old `file_types.json` that was previously used to make these
associations has been removed in favor of storing them on the default
theme.
Icon themes have two new fields on them:
- `file_stems`: A mapping of file stems to icon keys.
- `file_suffixes`: A mapping of file suffixes to icon keys.
These mappings produce icon keys which can then be used in `file_icons`
to associate them to a particular icon:
```json
{
"file_stems": {
"Makefile": "make"
},
"file_suffixes": {
"idr": "idris"
},
"file_icons": {
"idris": { "path": "./icons/idris.svg" },
"make": { "path": "./icons/make.svg" }
}
}
```
When loading an icon theme, the `file_stems` and `file_icons` fields
will be merged with the ones from the base icon theme, with the values
from the icon theme being loaded overriding ones in the base theme.
Release Notes:
- Added the ability for icon themes to provide their own file
associations.

Based on the feedback,
* made non-persisting font size change as a default in Zed keymaps
JetBrains IDEs seem to persist font size changes by default, hence left
to do so in Zed keymaps too
* fixed a bug with holding a binding to change the font size caused
flickering

Closes https://github.com/zed-industries/zed/issues/23505
Now `zed::IncreaseBufferFontSize` (and all the same UI- and
Buffer-related settings) action is parameterized with `{ "persist": true
}` (default).
Using `"persist": false` brings back resizing behavior prior to
https://github.com/zed-industries/zed/pull/23265
Release Notes:
- Added a way to toggle font size without settings adjustments
This PR updates the file icon mappings such that:
- C# (`.cs`) files map to the `csharp` key
- Cue (`.cue`) files map to the `cue` key
- GitLab YAML (`gitlab-ci.yml`) files map to the `gitlab` key
- Luau (`.luau`) files map to the `luau` key
- Solidity (`.sol`) files map to the `solidity` key
Release Notes:
- Icon themes: Added the ability to change the file icon for C# (`.cs`)
files.
- Icon themes: Added the ability to change the file icon for Cue
(`.cue`) files.
- Icon themes: Added the ability to change the file icon for GitLab YAML
(`gitlab-ci.yml`) files.

This PR adds support for configuring both a light and dark icon theme in
`settings.json`.
In addition to accepting just an icon theme name, the `icon_theme` field
now also accepts an object in the following form:
```jsonc
{
"icon_theme": {
"mode": "system",
"light": "Zed (Default)",
"dark": "Zed (Default)"
}
}
```
Both `light` and `dark` are required, and indicate which icon theme
should be used when the system is in light mode and dark mode,
respectively.
The `mode` field is optional and indicates which icon theme should be
used:
- `"system"` - Use the icon theme that corresponds to the system's
appearance.
- `"light"` - Use the icon theme indicated by the `light` field.
- `"dark"` - Use the icon theme indicated by the `dark` field.
Closes https://github.com/zed-industries/zed/issues/24695.
Release Notes:
- Added support for configuring both a light and dark icon theme and
switching between them based on system preference.
This PR updates the file icon mappings such that Markdown (`.md`,
`.markdown`) files map to the `markdown` key.
Release Notes:
- Icon themes: Added the ability to change the file icon for Markdown
(`.md`, `.markdown`) files.
This PR updates the file icon mappings such that Svelte (`.svelte`)
files map to the `svelte` key.
Release Notes:
- Icon themes: Added the ability to change the file icon for Svelte
(`.svelte`) files.
Closes#24353
This PR implements icon theme reload to ensure file icons are properly
updated whenever an icon theme extension is upgraded or uninstalled.
Currently, on both upgrade and uninstall of an icon theme extension the
file icons from the previously installed version will stay visibile and
will not be updated as shown in the linked issue. With this change, file
icons will properly be updated on extension upgrade or reinstall.
The code is primarily a copy for reloading the current color theme
adapted to work for icon themes. Happy for any feedback!
Release Notes:
- Fixed file icons not being properly updated upon icon theme upgrade or
uninstall.
This PR updates the file icon mappings for JSON (`.json`) file map to
the`json` key. Also, updates `.json` icon from `storage` to `code`.
This allows for the JSON file icons to be replaced in icon themes.
Release Notes:
- Icon themes: Added the ability to change the file icon for JSON
(`.json`) files.

This PR updates the file icon mappings such that HTML (`.html` and
`.htm`) files map to the `html` key.
This allows for the HTML file icons to be replaced in icon themes.
Release Notes:
- Icon themes: Added the ability to change the file icon for HTML
(`.html`, `.htm`) files.
Certain themes define the `created` and `deleted` status colors, but not
`created_background` and `deleted_background`. Previously, Zed would use
`created` and `deleted` colors, and apply a hard-coded opacity change,
but *not* use `created_background` and `deleted_background`, but that
behavior was inadvertently changed in
https://github.com/zed-industries/zed/pull/22994.
This PR restores the old behavior as a fallback. If a theme defines a
status color, but not the corresponding background color, we'll use a
75% transparent version of the foreground color as a fallback.
Release Notes:
- Fixed an issue in certain themes where diffs would render with the
wrong red and green colors for deletions and insertions.
This PR adds support for icon themes.
Closes https://github.com/zed-industries/zed/issues/8843.

### Extensions
Extensions can provide icon themes as well as the icons used in those
themes.
Icon themes are defined as JSON files in the `icon_themes` directory,
and icons included in the `icons` directory will be packaged up with the
extension.
All icon paths within an icon theme are interpreted relative to the root
of the extension.
See the [Material Icon
Theme](https://github.com/zed-extensions/material-icon-theme) extension
for an example.
Release Notes:
- Added support for icon themes.
- Extensions can now provide icon themes.
- Use the `icon theme selector: toggle` action to switch between
installed icon themes.
This PR fixes an issue where we weren't properly resolving directory and
chevron icons from icon themes the way we were for file icons.
We need to interpret the icon paths as relative to the extension
directory.
Release Notes:

There's still a bit more work to do on this, but this PR is compiling
(with warnings) after eliminating the key types. When the tasks below
are complete, this will be the new narrative for GPUI:
- `Entity<T>` - This replaces `View<T>`/`Model<T>`. It represents a unit
of state, and if `T` implements `Render`, then `Entity<T>` implements
`Element`.
- `&mut App` This replaces `AppContext` and represents the app.
- `&mut Context<T>` This replaces `ModelContext` and derefs to `App`. It
is provided by the framework when updating an entity.
- `&mut Window` Broken out of `&mut WindowContext` which no longer
exists. Every method that once took `&mut WindowContext` now takes `&mut
Window, &mut App` and every method that took `&mut ViewContext<T>` now
takes `&mut Window, &mut Context<T>`
Not pictured here are the two other failed attempts. It's been quite a
month!
Tasks:
- [x] Remove `View`, `ViewContext`, `WindowContext` and thread through
`Window`
- [x] [@cole-miller @mikayla-maki] Redraw window when entities change
- [x] [@cole-miller @mikayla-maki] Get examples and Zed running
- [x] [@cole-miller @mikayla-maki] Fix Zed rendering
- [x] [@mikayla-maki] Fix todo! macros and comments
- [x] Fix a bug where the editor would not be redrawn because of view
caching
- [x] remove publicness window.notify() and replace with
`AppContext::notify`
- [x] remove `observe_new_window_models`, replace with
`observe_new_models` with an optional window
- [x] Fix a bug where the project panel would not be redrawn because of
the wrong refresh() call being used
- [x] Fix the tests
- [x] Fix warnings by eliminating `Window` params or using `_`
- [x] Fix conflicts
- [x] Simplify generic code where possible
- [x] Rename types
- [ ] Update docs
### issues post merge
- [x] Issues switching between normal and insert mode

This PR ensures the background and border color of a project panel entry
is exactly the same with one exception: if the item is focused, active,
and not with mouse down. The point is to not be able to see the border
at all given they're there to act sort of akin to CSS's `outline` (which
doesn't add up to the box model).
Please let me know if there is any edge case I either messed up here or
didn't account for.

This PR adds the supporting infrastructure to support loading icon
themes defined by extensions.
Here's an example icon theme:
```json
{
"name": "My Icon Theme",
"author": "Me <me@example.com>",
"themes": [
{
"name": "My Icon Theme",
"appearance": "dark",
"file_icons": {
"gleam": { "path": "./icons/file_type_gleam.svg" },
"toml": { "path": "./icons/file_type_toml.svg" }
}
}
]
}
```
The icon paths are resolved relative to the root of the extension
directory.
Release Notes:

This PR updates the various `FileIcons` methods to fall back to the
default icon theme if the active icon theme does not have the desired
icon.
Release Notes:

This PR pulls the directory and chevron icons out of the
`IconTheme::file_icons` collection and promotes them to named fields.
This makes things less stringly-typed when looking up these icons.
Release Notes:
- N/A
This PR adds the initial concept of an `IconTheme` and refactors
`FileIcons` to use it to resolve the icons.
The `IconTheme` will ultimately be used to allow users to select a
different set of icons to use. Currently, however, this is just laying
the foundation for that work.
The association between file types and icons is now handled by the icon
theme when we resolve file icons. This mapping has been moved out of
`file_types.json` and into `icon_theme.rs`.
Release Notes:
- N/A
- [x] Rewrite worktree git handling
- [x] Fix tests
- [x] Fix `test_propagate_statuses_for_repos_under_project`
- [x] Replace `WorkDirectoryEntry` with `WorkDirectory` in
`RepositoryEntry`
- [x] Add a worktree event for capturing git status changes
- [x] Confirm that the local repositories are correctly updating the new
WorkDirectory field
- [x] Implement the git statuses query as a join when pulling entries
out of worktree
- [x] Use this new join to implement the project panel and outline
panel.
- [x] Synchronize git statuses over the wire for collab and remote dev
(use the existing `worktree_repository_statuses` table, adjust as
needed)
- [x] Only send changed statuses to collab

This PR reverts #20076 to turn the `ThemeRegistry` back into a regular
struct again.
It doesn't actually help us by having it behind a trait.
Release Notes:
- N/A
This PR converts the `ThemeRegistry` type into a trait instead of a
concrete implementation.
This allows for the extension store to depend on an abstraction rather
than the concrete theme registry implementation.
We currently have two `ThemeRegistry` implementations:
- `RealThemeRegistry` — this was previously the `ThemeRegistry` and
contains the real implementation of the registry.
- `VoidThemeRegistry` — a null object that doesn't have any behavior.
Release Notes:

This PR adds a theme preview tab to help get an at a glance overview of
the styles in a theme.

You can open it using `debug: open theme preview`.
The next major theme preview PR will move this into it's own crate, as
it will grow substantially as we add content.
Next for theme preview:
- Update layout to two columns, with controls on the right for selecting
theme, layer/elevation-index, etc.
- Cover more UI elements in preview
- Display theme colors in a more helpful way
- Add syntax & markdown previews
Release Notes:
- Added a way to preview the current theme's styles with the `debug:
open theme preview` command.
