A share extension puts TREK in the share sheet of Mail, Safari, Files, Wallet
and any app that shares a document, a link, text or a photo. It shows what came
in (a Wallet pass, a PDF, a mail, the page as Safari rendered it, text, a photo)
and the user's trips with their covers, the next one already picked, and hands
both to the app, which opens that trip's booking import with the file in place.
"Choose later" leaves the trip question to the app's import sheet as before.
- ShareExtension target (add-extension.rb learns "share": JavaScript and the
localizations go in as resources), bundle com.liketrek.trek.share, signed in
the release lane, its plists linted in native.yml
- Safari hands over the rendered page (SharePage.js), so a confirmation behind
a sign-in arrives whole; other apps' links are fetched
- The item travels through the shared keychain group the widgets already use;
the app takes it on com.liketrek.trek://share or when it next becomes active
- Feature shareSheet; strings in the app's 28 languages
TREK now appears under "Open in" and in the share sheet for PDFs, calendar
entries, Wallet passes and mails (iOS document types, Android VIEW and SEND
filters). The native side reads the file (up to 15 MB) and hands it to the UI,
which asks which trip it belongs to, upcoming trips first, then opens that
trip's booking import with the file already chosen.
