AltText

On this page

What an image shows, for someone who can't see it.

Use it beside each image a person might read about. An image with nothing to say has none, not empty text. For a long caption, use Text.

Shape

One value, held as text in one set form, with no parts: Logo.

example

AltText("A red bicycle leaning against a brick wall")

AltText(raw) checks the text, and text that isn't one breaks the format rule.

text.parse(raw, as: AltText) reads one from text that comes from outside. Text that isn't one at all fails malformed, such as Logo or Logo .

A string, in a request, a response or json.write:

json

"A red bicycle leaning against a brick wall""Logo"

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

AltText is in the group Media and visual, and has been in Jadpo since 0.1.0.

text.from writes one standard text form, the same form text.parse reads back: A red bicycle leaning against a brick wall and Logo.

It is stored in one column named for the field, of type text. Logo is stored as 'Logo'.

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

With locale: Locale.en_gb:

Value	Shown
`A red bicycle leaning against a brick wall`	`A red bicycle leaning against a brick wall`
`Logo`	`Logo`

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