gpui and gpui_platform now come from Zed's repo by git at 1a28cff,
the code gpui-pre 0.3.7 republishes, so the gallery can later build
for the browser. gpui takes stacker, as 0.2.2 always did, and
gpui_platform takes font-kit, without which macOS draws no text;
runtime_shaders moves to gpui_platform.
The API moved: focus, blur and Tab steps take cx, Corner is Anchor,
shaped lines paint with an alignment, defer_draw takes a content
mask, the inspector registers a factory, async updates return their
value, and wrapped lines are shared, not cloned. Updates through a
window context go through the window, so a closed window still ends
them as it did.
Where the new gpui behaves differently, Ely keeps its old intent.
Holds and reveals under a resting pointer survive typing through
gpui's input-modality-independent hover; previews the keyboard also
moves keep the default, and the calendar's leave ignores a key press.
Enter reaches a button inside the code editor, since gpui now arms a
key click on the press. The event logger skips a lone modifier. A
video and an image grid keep their shape in a flex column under
taffy 0.13, as a picture does.
AGENTS.md records the new stack and the rules this port changes; the
rest of the old gpui and taffy rules are re-tested in T44c.
A raise inside another was namespaced by its place in the layer's
queue, so one that came before it moved its id path and rebuilt its
keyed state and focus: an open date popup would lose its month when a
tip appeared. raise now takes its owner's id and draws under it, and
float and float_height pass the owner's id on from every call site.
A test holds a focused box in a raise while another comes before it.
gpui 0.2.2 asserts on a deferred draw inside another, and every dialog,
sheet and popover draws inside one, so opening a date field in the
snooze or schedule dialog panicked, as would any list, menu or picker
opened in an overlay. primitives::raise replaces each deferred draw:
at the top it defers as before; inside something raised it leaves a
placeholder in the tree, and its layer lays it out on its own, then
draws it last. check.sh refuses gpui's deferred anywhere else.
The time dialog's rule is now times::ahead, tested for a moment
behind, now itself, a moment ahead and another zone; a gpui test picks
yesterday in the snooze dialog, sees that it has passed and that
nothing is sent, then picks two days ahead and hears that moment.
