Update documentation 2015-01-30 09:40:06 +01:00			`# Vowel`

Change how documentation of rules are presented Rules are not always used from the alias `v`, neither called staticaly. 2017-03-27 14:47:07 +02:00			- `Vowel()`
Use variadics "AbstractFilterRule" rule Since the library doesn't need to give support to version 5.4 or less of PHP using variadics in the constructor of "AbstractFilterRule" seems better than doing the whole validation. This commit will also apply the contribution guidelines to "AbstractFilterRule" and use a better naming for it.

Update documentation 2015-01-30 09:40:06 +01:00
Apply contribution guidelines to "Vowel" rule After writing the integration tests of the "Vowel" rule we noticed that it is generating extra double-quotes for the "{{additionalChars}}" template placeholder. Besides, it considers any whitespace as valid. That is because in the past Validation would always consider spaces as a valid. This commit will also remove the extra double-quotes and do not allow whitespaces to be considered as valid.
