Recipient chips could already be dragged between the To/Cc/Bcc fields, but a
drop always appended and same-field drops were a no-op, so recipients could not
be rearranged without deleting and re-adding them.
Add positional drag-and-drop: while dragging a chip, an insertion caret shows
the gap it would land in (based on which half of the hovered chip the pointer
is over, mirrored for RTL); dropping inserts it there.
- same-field drop reorders the chip locally (via onChipsChange), using the
source index carried in the drag payload (fromIndex) and adjusting for the
removal shift; dropping onto its own position is a no-op;
- cross-field drop inserts at the drop position: handleMoveChip gained an
optional toIndex (omitted = append, e.g. dropping onto a hidden Cc/Bcc
button, preserving existing behaviour);
- per-chip onDragOver computes the target gap; the container handles the
trailing gap (past the last chip / over the input).
No new user-facing strings (the caret is purely visual), so no locale changes.
Tests (components/email/__tests__/recipient-chip-drag.test.tsx): reorder to end
/ front, self-drop no-op, cross-field positional insert, and caret visibility.
Also add the missing findComposeIdentityId export to the reply-identity mock in
the recipient drag/paste suites so <EmailComposer> mounts in compose mode.
The recipient chip-drag and paste tests render <EmailComposer>, which since
b716f95a (feat(compose): preselect identity of the active mailbox) calls
findComposeIdentityId() from @/lib/reply-identity in compose mode. Both tests
mock that module but only returned resolveReplyFrom, so vitest threw
"No 'findComposeIdentityId' export is defined on the mock" on mount,
failing all 18 tests. Add the missing export (returns null; the composer
guards with if (composeIdentityId)).
Pasting a list of addresses into To/Cc/Bcc now creates one chip per
address instead of dropping the whole blob in as a single invalid chip.
A paste is split only when it actually contains a separator; a lone
address falls through to normal editing.
- Separators: commas, semicolons, and any whitespace/newline - covers
comma/space dumps, spreadsheet columns and Outlook-style `;` lists.
- Display names are preserved: `Name <email>`, a fully-quoted
`"Name <email>"` entry, and `"Doe, John" <email>` (comma inside a
quoted name) each stay a single chip with the name intact.
- Bare-address runs split per address; a `<addr>` token is unwrapped;
tokens that aren't valid addresses are left behind in the input for
the user to fix rather than becoming junk chips.
- Deduped case-insensitively within the paste and against existing chips.
Implemented as splitPastedRecipients in email-composer-utils, layered on
the shared quote/angle-aware splitter: splitRecipients gains an optional
`separators` argument so the composer/mailto serialization boundary
(comma-only) and the paste path (`,;\n\r`) share one implementation.
Wired into the recipient chip input's onPaste handler (To/Cc/Bcc).
Alternative to the quote-aware string fix: represent committed To/Cc/Bcc
recipients as Recipient[] ({name?, email}) with a separate input-text
string per field, instead of a single comma-joined string parsed with
split(','). Structured recipients can never be torn apart on a delimiter,
so a display name containing a comma ("Doo, John <john@doo.org>", as
produced on Reply-All) stays a single chip.
- email-composer-utils: add Recipient type, parseRecipient/formatRecipient,
and parseRecipientList/formatRecipientList for the (de)serialization
boundary (ComposerDraftData stays a string; quoting keeps it lossless).
Remove the now-unused string-chip helpers.
- email-composer: to/cc/bcc are Recipient[]; toInput/ccInput/bccInput hold
the in-progress text. Reply/forward init, autocomplete, chip edit, drag &
drop (payload now carries the structured recipient), send/draft/validation
and template paths all operate on arrays. withInput() folds uncommitted
typed text into the send/validation set.
- Tests updated for the array contract; add comma-in-name chip coverage.
Adds native HTML5 drag-and-drop so users can move recipient email
address chips between the To, CC, and BCC fields in the composer.
Chips dragged onto the Cc/Bcc toggle buttons auto-reveal the hidden
field and place the chip there.
