We were previously retaining Options on the Surface struct, but other
than userdata, we only use those values for initialization. Instead,
store just the opaque userdata value on the Surface and clarify that
Surface.Options are only used for initialization.
Normally, when `ctrl+<character>` is pressed, such as `ctrl+z` or
`ctrl+c`, macOS (AppKit) doesn't do any key translation because that
doesn't map to any printable text on its own. Ghostty does the
translation to correctly determine the character is "z" or "c" or
whatever.
For some reason when the keyboard layout is "Dvorak - QWERTY Cmd"
specifically (_not_ plain "Dvorak") on a US layout keyboard, AppKit
decides that "ctrl+z" ("/" on a qwerty keyboard) translates to "/"...
I can't find any explanation for this.
To workaround this, this commit makes it so that if the following
conditions are true, then we IGNORE AppKit's text translation and
manually do it using UCKeyTranslate:
(1) We're on macOS specifically (not iOS, etc.)
(2) We have a key event with ONLY control pressed
This fixes `ctrl+z` on this unique Dvorak keyboard layout.
Fixes#965
When processing keybindings that closed the surface (`close_surface`,
`close_window`), the surface and associated runtime structures would be
freed so we could segfault.
This PR introduces a new enum result for input events (only key for now)
that returns whether an event resulted in a close. In this case, callers
can properly return immediately and avoid writing to deallocated memory.
In practice, the primary and selection clipboards are treated exactly
the same, but this allows OSC 52 sequences to use either 's' or 'p' as
the clipboard target.
This enables shifted alt-prefixed keys, such as `shift+alt+.` on
US standard becoming `M->`. To do this, we needed to fix a few bugs:
(1) translation mods should strip alt even if other mods are set
(2) AppKit translation event needs to construct new characters with
the translation mods.
(3) Alt-prefix handling in KeyEncoder needs to allow ASCII utf8
translations even for macOS.
Fixes#872
In #867 we fixed macos-option-as-alt, but unfortunately AppKit ALSO does
some translation so some behaviors were not working correctly.
Specifically, when you had macos-option-as-alt set, option+e would
properly send `esc+e` to the pty but it would ALSO set the dead key
state for "`" since AppKit was still translating the option key.
This commit introduces a function to strip alt when necessary from the
translation modifiers used at the AppKit layer, preventing this
behavior.
Instead of making a separate enum that must be translated from the
ClipboardRequest type, simply re-use ClipboardRequest to determine the
clipboard confirmation reason.
The resizeIncrements property is only modified when the cell size of the
focused window changes. If two splits have the same cell size then the
property is not modified when focusing between the two splits.
