Valider

The Valider module to check rate of invalid action/event/behaviour, and return a final status to you.

Valider include features:

• continuous invalid X times, or
• invalid X times in Y seconds

will report as once. and

• support multi-tags in a checker
• very clean & small, little memory, and faster!

Install & Usage

download the Valider.lua file and put into lua search path or current directory.

load it as a file module from lua. use Valider:new() to get checker object.

local Valider = require('Valider')
local checker = Valider:new()

if checker:invalid('tag') then
	-- do something when status is invalid
	..
end

Options

you can create checker with options.

local options = {
	-- count one continuous-invalid, when less maxContinuousInterval between two invalids
	maxContinuousInterval = 3,

	-- report as once when continuous-invalid count >= maxContinuous
	--	*) continuous invalid X times
	maxContinuous = 100,

	-- report as once when invalid count >= maxTimes, in maxSeconds
	--	*) invalid X times in Y seconds history
	maxTimes = 30,
	maxSeconds = 30,
}

-- get checker with options
--	*) or <nil> for default
local checker = Valider:new(options)

..

Multi-tags checker

with tags, you can check multi source action/event/behaviour. the tag is anything(string/boolean/table in lua). for examples:

local checker = Valider:new()

if checker:invalid('network hardware invalid') then
	..
end

if checker:invalid('server connection lost') then
	..
end

if (checker:invalid(a_table_variant) or
	checker:invalid(a_boolean_variant) or
	checker:invalid(any_data_as_key_of_lua_table)) then
	..
end
