Wrapping ~1,000 strings by hand is a thousand chances to mistype the copy
itself, and a parser does not get bored. scripts/i18n-extract.mjs does the
mechanical part -- JSX text and the attributes a person actually reads -- and
refuses the rest rather than guessing. 78% now: 515 wrapped, 143 left.
What it refuses matters as much as what it does. Text split around an
interpolation arrives as separate fragments, and wrapping each on its own
produces "Move " and " messages", which no translator can do anything with;
those are listed for a person to rebuild as sentences. So is anything
containing a double quote, which would end the literal.
Three things it had to be taught, each found by running it:
- <code>, <kbd> and <pre> are not prose. The first run wrapped `label:name`
inside <code> -- a search operator, where translating it breaks the thing it
documents. Subtrees marked translate="no" are skipped for the same reason.
- `t` is a natural name for a callback parameter and several files already use
it, so an import called `t` is shadowed inside those callbacks -- silently,
wherever the local happens to be callable. The name is checked per file now
and aliased to `translate` where it is taken.
- JSX decodes HTML entities and a JS string literal does not, so
`Language & region` moved into t("...") and rendered the entity on screen.
That last one is the one worth remembering. Typecheck passed, 443 tests
passed, and the page said "Language & region" in plain sight. It took
looking at a screenshot, and then a sweep of ten views to find the second
occurrence in a sentence I had written by hand earlier the same day. Nothing
in the toolchain was ever going to catch it: it is valid TypeScript rendering
valid text that happens to be wrong.
The codemod decodes entities now, and checks for a quote after decoding rather
than before.
ihasmail's mail list was built for a mouse. A row is clicked, right-clicked
and dragged into a folder, and on a touchscreen two of those three do not
exist -- so the phone layout had the shape of a mail app and none of the
handling, and the things people reach for first simply did nothing.
Four gestures, all touch-only, so a mouse keeps drag-to-folder unchanged:
- Swipe a row sideways to act on it. Each direction is a setting -- right
archives and left deletes by default, matching the app the phone came
with -- and the strip revealed behind the row names what will happen in
the folder it is happening in: "Delete forever" out of Deleted Items,
"Not spam" inside Junk Mail, and nothing at all where the action is a
no-op, in which case the row will not move that way.
- Hold a row to select it. Selection was reachable already, by aiming at a
checkbox beside an avatar, which is not how anyone selects mail on a
phone. The selection toolbar gained an overflow menu at the same time:
report spam, mark unread and label were hidden on narrow screens and had
nowhere else to be, so touch selection could not reach them at all.
- Hold a folder for the menu its ⋮ button opens.
- Pull the list down to refresh, and drag in from the left edge of a
conversation to go back. The toolbar's button and arrow both stay: a
gesture with no visible control is one only the people who already know
about it can use.
The arithmetic behind them is in lib/touch.ts, away from the components and
under test, because the numbers are the whole thing: an axis lock biased
towards the vertical, so a diagonal flick stays a scroll rather than
deleting whatever it passes over.
Two layout bugs turned up while checking this on a 390px screen, both
older than the gestures. The app shell is a grid with only its rows named,
so it took an implicit auto column sized to the top bar's min-content --
about 470px -- and every message row ran off the right of the glass with
its date beyond the edge. The column is now stated as minmax(0, 1fr), and
the search field is allowed to shrink. Full-screen surfaces measure in dvh
rather than vh, and the tab bar, drawer and compose button keep out from
under the notch and the home indicator.
