# `WritingScript`

A writing system, written as its four-letter code: `Latn`, `Jpan`.

Use it when the script matters separately from the language, such as Serbian in Latin or Cyrillic, or choosing a font. Most apps want [`Language`](/docs/types/type-language.md) or [`Locale`](/docs/types/type-locale.md).

## Shape

One of 224 values, such as `WritingScript.adlm`, written `Adlm`. Details has them.

## Example

```jadpo
WritingScript.latn
```

`text.parse(raw, as: WritingScript)` reads one from text that comes from outside. Text that isn't one at all fails `malformed`, such as `latin`, `Lat` or `Latnn`.

## Good to know

- The value's name is lower case, `WritingScript.latn`, but it is written `Latn`.
- `==` tells you whether two are the same. `<` and `list.sort_by` don't take it.

## In JSON

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

```json
"Jpan"
"Latn"
"Zyyy"
```

`WritingScript` is in the group Places, 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: `Jpan`, `Latn` and `Zyyy`.

### How it is stored

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

### How it is shown to people

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

With `locale: Locale.en_gb`:

| Value | Shown |
|---|---|
| `Jpan` | `Japanese` |
| `Latn` | `Latin` |
| `Zyyy` | `Common` |

### Operations

It also takes `text.parse`, `text.from`, `text.format`, `json.read`, `json.write` and `==`. [How every standard type behaves](/docs/every-standard-type-meets-one-contract.md) says how they work.
