Sathwik ChirivelliandChristopher Biscardi 97e5d4f630 solo_diff_view: Show changes only by default (#59958)
# Objective

- Default the solo diff view to show changed hunks with excerpted
context instead of expanding the entire file.
- Closes https://github.com/zed-industries/zed/issues/59489

## Solution

- Initialize the solo diff editor with excerpts around changed hunks.
- Add a header toggle for switching between the excerpted changes-only
view and the full-file view.
- Keep both sides of the split diff visually aligned when excerpts are
collapsed.

## Testing

- `cargo check -p git_ui`
- `cargo test -p git_ui`

## Self-Review Checklist:

- [x] I've reviewed my own diff for quality, security, and reliability
- [x] Unsafe blocks (if any) have justifying comments
- [x] The content adheres to Zed's UI standards
([UX/UI](https://github.com/zed-industries/zed/blob/main/CONTRIBUTING.md#uiux-checklist)
and
[icon](https://github.com/zed-industries/zed/blob/main/crates/icons/README.md)
guidelines)
- [ ] Tests cover the new/changed behavior
- [x] Performance impact has been considered and is acceptable

Licensing

Zed source code is licensed primarily under GPL-3.0-or-later, with Apache-2.0 components where marked.

License information for third party dependencies must be correctly provided for CI to pass.

We use cargo-about to automatically comply with open source licenses. If CI is failing, check the following:

  • Is it showing a no license specified error for a crate you've created? If so, add publish = false under [package] in your crate's Cargo.toml.
  • Is the error failed to satisfy license requirements for a dependency? If so, first determine what license the project has and whether this system is sufficient to comply with this license's requirements. If you're unsure, ask a lawyer. Once you've verified that this system is acceptable add the license's SPDX identifier to the accepted array in script/licenses/zed-licenses.toml.
  • Is cargo-about unable to find the license for a dependency? If so, add a clarification field at the end of script/licenses/zed-licenses.toml, as specified in the cargo-about book.

Sponsorship

Zed is developed by Zed Industries, Inc., a for-profit company.

If you’d like to financially support the project, you can do so via GitHub Sponsors. Sponsorships go directly to Zed Industries and are used as general company revenue. There are no perks or entitlements associated with sponsorship.
