Standard types

TextDirection

On this page

Which way text runs, written as HTML's dir writes it, ltr and rtl: what locale.direction gives.

Places; not ordered; since Jadpo 0.1.0.

Make one

Pick one of its variants, TextDirection.left_to_right.

text.parse(raw, as: TextDirection) reads one from its text; text that isn't one at all fails malformed, such as left_to_right, auto or "".

This operation gives one: locale.direction.

Variants

Variant Written
left_to_right ltr
right_to_left rtl

Text, JSON and storage

text.from writes its canonical text, the one form text.parse reads back. JSON sends its canonical text as a string.

Text JSON
ltr "ltr"
rtl "rtl"

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

Shown to people

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

With locale: Locale.en_gb:

Value Shown
ltr ltr
rtl rtl

Operations

  • locale.direction(value: Locale) -> TextDirection: Which way value's text runs, as CLDR says: TextDirection.left_to_right for English, TextDirection.right_to_left for Arabic and Hebrew.

Like every standard type, it also has the contract's own operations: text.parse, text.from, text.format, json.read, json.write and ==. It isn't ordered, so < and sorting don't take it. Every standard type meets one contract says how they work.
