John Tur 2ead8c42fb Improve Windows text input for international keyboard layouts and IMEs (#41259)
- Custom handling of dead keys has been removed. UX for dead keys is now
the same as other applications on Windows.
- We could bring back some kind of custom UI, but only if UX is fully
compatible with expected Windows behavior (e.g. ability to move the
cursor after typing a dead key).
  - Fixes https://github.com/zed-industries/zed/issues/38838
- Character input via AltGr shift state now always has priority over
keybindings. This applies regardless of whether the keystroke used the
AltGr key or Ctrl+Alt to enter the shift state.
- In particular, we use the following heuristic to determine whether a
keystroke should trigger character input first or trigger keybindings
first:
- If the keystroke does not have any of Ctrl/Alt/Win down, trigger
keybindings first.
- Otherwise, determine the character that would be entered by the
keystroke. If it is a control character, or no character at all, trigger
keybindings first.
- Otherwise, the keystroke has _any_ of Ctrl/Alt/Win down and generates
a printable character. Compare this character against the character that
would be generated if the keystroke had _none_ of Ctrl/Alt/Win down:
- If the character is the same, the modifiers are not significant;
trigger keybindings first.
- If there is no active input handler, or the active input handler
indicates that it isn't accepting text input (e.g. when an operator is
pending in Vim mode), character entry is not useful; trigger keybindings
first.
- Otherwise, assume the modifiers enable access to an otherwise
difficult-to-enter key; trigger character entry first.

  - Fixes https://github.com/zed-industries/zed/issues/41486
- TranslateMessage calls are no longer skipped for unhandled keystrokes.
This fixes language input keys on Japanese and Korean keyboards (and
surely other cases as well).
- To avoid any other missing-TranslateMessage headaches in the future,
the message loop has been rewritten in a "traditional" Win32 style,
where accelerators are handled in the message loop and TranslateMessage
is called in the intended manner.

  - Fixes https://github.com/zed-industries/zed/issues/40638
- As a bonus, Alt+Space now opens the system menu, since it is triggered
by the WM_SYSCHAR generated by TranslateMessage.
- VK_PROCESSKEYs are now ignored rather than being unwrapped and matched
against keybindings. This ensures that IMEs will reliably receieve
keystrokes that they express interest in. This matches the behavior of
native Windows applications.

Licensing

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.
