7db3bea8a6Improves SPDX header linting to ensure consistent license metadata across the codebase. Key changes: - Enforce deterministic tag ordering (License-Identifier, FileCopyrightText, FileContributor) to ensure consistency, prevent merge conflicts, and simplify code reviews - Add contributor alias mapping to consolidate contributors with multiple emails or name variations (e.g., "nickl-" → "Nick Lombard") - Add --contributions-strategy option with "blame" (current code authors) and "log" (all historical contributors) to support different attribution philosophies - Add optional path argument to lint specific files or directories - Add --fix option to automatically correct header issues Assisted-by: Claude Code (claude-opus-4-5-20251101)

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