Baris Palaska 084b5d21f6 gpui_web: Implement clipboard write and paste (#60890)
# Objective

write_to_clipboard was a no-op and read_from_clipboard returned None.

## Solution

Writes go through the browser's asynchronous Clipboard API,
fire-and-forget, invoked synchronously inside the user's input event so
the user-activation requirement holds.

Reads cannot be implemented the same way: the async clipboard read API
cannot fit read_from_clipboard's synchronous signature. Paste is instead
delivered by a DOM paste listener on the hidden input, whose
ClipboardEvent exposes clipboardData synchronously; the text feeds the
active input handler. This covers keyboard-, menu-bar- and
context-menu-initiated paste. Note the keyboard path requires the paste
chord's keydown to reach the browser unconsumed (apps should not bind
cmd/ctrl-v on web).

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.
