Yes

• Yes()
• Yes(bool $locale)

Validates if the input considered as "Yes".

v::yes()->validate('Y'); // true
v::yes()->validate('Yea'); // true
v::yes()->validate('Yeah'); // true
v::yes()->validate('Yep'); // true
v::yes()->validate('Yes'); // true

This rule is case insensitive.

If $locale is TRUE, it will use the value of nl_langinfo with YESEXPR constant, meaning that it will validate the input using your current location:

setlocale(LC_ALL, 'pt_BR');
v::yes(true)->validate('Sim'); // true

Be careful when using $locale as TRUE because the it's very permissive:

v::yes(true)->validate('Yydoesnotmatter'); // true

Besides that, with $locale as TRUE it will consider any character starting with "Y" as valid:

setlocale(LC_ALL, 'ru_RU');
v::yes(true)->validate('Yes'); // true
