Focuslight::Validator

Validate http request parameters (or others) by defined rule, without models.

SYNOPSIS:

require 'focuslight-validator'

result = Validator.validate(params, {
  :request_param_key_name => { # single key, single value
    :default => default_value,
    :rule => [
      Validator.rule(:not_null),
      Validator.rule(:int_range, 0..10),
    ],
  },
  :array_value_key_name => { # single key, array value
    :array => true
    :size => 1..10 # default is unlimited (empty also allowed)
    # default cannot be used
    :rule => [ ... ]
  }
  # ...
  [:param1, :param2, :param3] => { # rule for combination of 2 or more params
    # default cannot be used
    :rule => Validator::Rule.new(->(p1, p2, p3){ ... }, "error_message")
  },
}

result.has_error? #=> true/false
result.errors #=> Hash( { param_name => "error message" } )
