Standard types

Markdown

On this page

CommonMark text, with no control character but a tab, a line feed or a carriage return; markup.to_html renders it as Html.

Text formats; not ordered; since Jadpo 0.1.0.

Make one

Build one from its text, Markdown("Fresh **soup** daily."), which checks it: text that isn't one breaks format.

text.parse(raw, as: Markdown) reads one from its text; text that isn't one at all fails malformed, such as "a\u0000b" or "ring the bell\u0007".

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
Fresh **soup** daily. "Fresh **soup** daily."
# Soups\n\n- Leek\n- Tomato "# Soups\n\n- Leek\n- Tomato"
Tom & Jerry "Tom & Jerry"
Visit [our site](https://example.com/).\r\n "Visit [our site](https://example.com/).\r\n"

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

Shown to people

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

With locale: Locale.en_gb:

Value Shown
Fresh **soup** daily. Fresh soup daily.
"# Soups\n\n- Leek\n- Tomato" "Soups\nLeek\nTomato"
Tom & Jerry Tom & Jerry
"Visit [our site](https://example.com/).\r\n" Visit our site.

Operations

  • markup.to_html(markdown: Markdown) -> Html: markdown rendered as CommonMark (0.31.2), then made safe as every Html is: raw HTML inside it is kept only where the sanitiser keeps it, and an image is shown as its description, since Html keeps no images.

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.
