Introduces a Markdown linter for checking the Changelog format. "See Also" was transformed into a section to make it easier to handle it with the `Content` class. The "Related" linter was simplified to reflect that change too. An additional "alignment" parameter was added to markdown table generators, allowing the padding and headers to be explicitly marked with a specific left (-1), middle (0) or right(1) alignment. Existing files were fixed using the `fix` option after the changes.

# IterableVal
|
|
|
|
- `IterableVal()`
|
|
|
|
Validates whether the input is an iterable value, in other words, if you can iterate over it with the [foreach][] language construct.
|
|
|
|
```php
|
|
v::iterableVal()->assert([]);
|
|
// Validation passes successfully
|
|
|
|
v::iterableVal()->assert(new ArrayObject());
|
|
// Validation passes successfully
|
|
|
|
v::iterableVal()->assert(new stdClass());
|
|
// Validation passes successfully
|
|
|
|
v::iterableVal()->assert('string');
|
|
// → "string" must be an iterable value
|
|
```
|
|
|
|
## Note
|
|
|
|
This validator doesn't behave as PHP's [is_iterable()][] function because it considers that you can iterate over any object.
