48405271c5The `{{name}}` placeholder could represent different things depending on
the state of the Result, and referring to it as `{{name}}` seems
arbitrary. This commit changes it to `{{subject}}`, which is much more
generic and it describes well what that placeholder can mean.

# LanguageCode
|
|
|
|
- `LanguageCode()`
|
|
- `LanguageCode("alpha-2"|"alpha-3" $set)`
|
|
|
|
Validates whether the input is language code based on [ISO 639][].
|
|
|
|
**This rule requires [sokil/php-isocodes][] and [sokil/php-isocodes-db-only][] to be installed.**
|
|
|
|
```php
|
|
v::languageCode()->isValid('pt'); // true
|
|
v::languageCode()->isValid('en'); // true
|
|
v::languageCode()->isValid('it'); // true
|
|
v::languageCode('alpha-3')->isValid('ita'); // true
|
|
v::languageCode('alpha-3')->isValid('eng'); // true
|
|
```
|
|
|
|
This rule supports the two[ISO 639][] sets:
|
|
|
|
- `alpha-2`
|
|
- `alpha-3`
