The gallery's entry runs natively or, on wasm32, from a wasm_bindgen start
through gpui_web, single-threaded with WebGL2 fallback. ?page, ?story and
?theme choose what shows; an unknown one fails in the page and the log.
set_theme switches the mode later. Pictures load from ELY_GALLERY_ASSETS.
scripts/stories.py writes examples/gallery/stories.json from the pages.
Every page and scripted state was shot with gpui 0.2.2 and with the
port, light and dark, full width and at 280px, judged pair by pair by
agents with skeptics, and every page's log diffed. What differed is
fixed, each with a test that fails without it where the test platform
can show it:
- The gallery's harness takes posted mouse moves (gpui_macos listens
to a tracking area), posts each drag move twice (it no longer
replays a held drag), and waits three frames before each shot.
- Rolling digits: a block column, so taffy 0.13 lends the cell no
baseline, and a line of whole device pixels, since gpui snaps each
length on its own. DescriptionList's row aligns ends.
- Margins that taffy 0.13 collapses through a plain block: the
drawer's pull and snap, the stagger and transition rise, the dialog
and palette rises, the fullscreen dialog's slide.
- An Input keeps room to type in a squeezed row; the field rows drop
w_full, whose reason was taffy 0.9's.
AGENTS.md's rules that named gpui 0.2.2 or taffy 0.9 were re-tested
against both sources and rewritten, and new ones say what the port
changed. TASKS.md's tags follow: what the new gpui makes possible is
prove. Captions, doc comments and README say what holds now.
i18n::SkipLink holds a Tab stop in flow at zero size, first where it
sits, and while focused raises a pill over the page; Enter, Space or a
press hands focus to its target. gpui orders stops by tab_index before
paint and registers none for an invisible element, so the stop stays in
flow and only the pill is raised. Theme::set_color_blind_safe swaps Ely's
chart hues for a set fitted to stay apart under Machado's protanopia,
deuteranopia and tritanopia; a test holds every pair 0.10 apart in Oklab
and each hue 3:1 on its page, and red against green shows the measure
bites. KeyboardNavigationHelper points to interaction::RovingFocus. The
announcer, labels and screen-reader text stay blocked: gpui 0.2.2 has no
accessibility tree, and nothing here is trusted to observe VoiceOver.
The i18n tests move under src/i18n/tests.
gpui sets no paragraph direction, so CoreText took a Hebrew line whose
first strong character was Latin, or the left-to-right mark of a signed
number, as left to right and swapped its parts. I18n::text now leads a
right-to-left message with U+200F; the number keeps CLDR's U+200E, so
its sign stays at the digits' left. The demo adds a change that opens
with a signed number, in every catalog; under Hebrew it lies at the
line's right end. A test holds the marks on a message that starts with
a number and one that starts with a Latin name.
gpui 0.2.2 wraps shaped glyphs in the order they are drawn, so a
right-to-left line that wraps comes out garbled. The demo's Hebrew
lines are Ellipses, which cut by characters, and an Ellipsis now sits
by its text's alignment, so a short line under text_right lies at the
right; the editor's completion details take the side they ask for. A
right-to-left locale leads a minus with a left-to-right mark, as CLDR
does, so the sign stays at the digits' left inside Hebrew. en-US and
de-DE write CLDR's two-digit year. The repeated-key and second-catalog
guards have tests.
i18n::I18n is a gpui global holding the shown locale and one catalog of
messages per locale. text fills each {name} from its arguments; a
missing key, argument or catalog fails, and every catalog holds the
first one's keys. Locale writes numbers with its separators and dates
in CLDR's short numeric form; Hebrew replaces Arabic, whose Egyptian
digits Ely does not write. Direction::row mirrors a stack and
Direction::align sets text against the reading side. The gallery's
chapter 40 shows the messages in seven locales, every locale's number
and date, and a file list that mirrors under Hebrew.
