EmailWithName

An email address with the name shown beside it: Mary Somerville <mary@example.com>.

On this page

An email address with the name shown beside it: Mary Somerville <mary@example.com>.

Use it for the sender or recipient of a message when the name should appear in the reader's mail app. When you only need the address, use Email.

Shape

Field Type Required?
name Text No
address Email Yes

Write every field when you build one, and give a field that isn't required as none.

Example

example
EmailWithName { name: "Mary Somerville" address: "mary@example.com" }

text.parse(raw, as: EmailWithName) reads one from text that comes from outside. Text that isn't one at all fails malformed, such as Mary Somerville, <mary@example.com> or Mary Somerville <mary>.

Good to know

  • text.parse also reads a bare mary@example.com, and gives it name: none.
  • == tells you whether two are the same. < and list.sort_by don't take it, so sort by one of its parts instead.
  • A field that holds one counts as personal data (contact), so you don't mark it yourself.

In JSON

An object of its parts, in a request, a response or json.write:

json
{"name":"Mary Somerville","address":"mary@example.com"}{"name":"Somerville, Mary","address":"mary@example.com"}{"name":null,"address":"mary@example.com"}

When you read one, a field that isn't required may be left out, or sent as null.

Details

Text form, storage, how it is shown, and operations

EmailWithName is in the group People and contact, and has been in Jadpo since 0.1.0.

Text form

text.from writes one standard text form, the same form text.parse reads back: Mary Somerville <mary@example.com>, "Somerville, Mary" <mary@example.com> and mary@example.com.

How it is stored

It is stored in 2 columns, each named for the field, _ and its suffix. This is "Somerville, Mary" <mary@example.com>:

Column Type Holds
<field>_name text 'Somerville, Mary'
<field>_address text 'mary@example.com'

How it is shown to people

text.format(value, locale:) shows it to people in their locale.

With locale: Locale.en_gb:

Value Shown
Mary Somerville <mary@example.com> Mary Somerville <mary@example.com>
"Somerville, Mary" <mary@example.com> "Somerville, Mary" <mary@example.com>
mary@example.com mary@example.com

Operations

It also takes text.parse, text.from, text.format, json.read, json.write and ==. How every standard type behaves says how they work.
