methods

@.append value

String::append = (value)->
    @ + if value then value else ''

@.add_Random_Chars size

String::add_Random_Chars     = (size )-> @ + crypto.randomBytes(size || 10)
String::add_Random_String    = (size )-> @ + crypto.randomBytes(size || 10).toString('hex').slice(0,size|| 10)
String::add_Random_Letters   = (size )->
                                         charSet = 'abcdefghijklmnopqrstuvwxyz'
                                         @ + (charSet[Math.floor(Math.random() * charSet.length)]  for i in [1..size]).join('')
String::add_5_Random_Letters = (     )-> @.add_Random_Letters(5)
String::add_Random_Numbers   = (size )->
                                         charSet = '0123456789'
                                         @ + (charSet[Math.floor(Math.random() * charSet.length)]  for i in [1..size]).join('')
String::after                = (value)-> if ((index = @.indexOf(    value)) == -1 ) then '' else @.substr(index + value.size())
String::after_Last           = (value)-> if ((index = @.lastIndexOf(value)) == -1 ) then '' else @.substr(index + value.size())
String::before               = (value)-> @.substring(0,@.indexOf(value))
String::before_Last          = (value)-> @.substring(0,@.lastIndexOf(value))

@.contains value

Checks that value is inside @. If value is an Array, then all elements are expected to be found inside @

String::contains = (value)->
    if value instanceof Array
        for item in value
            if @.indexOf(item) == -1
                return false
        return true
    else
        @.indexOf(value) > -1


String::ends_With            = (value)-> if not value then false else @.toString().slice(-value.length)==value
String::lower                = (     )-> @.toLowerCase()
String::not_Contains         = (value)-> @.indexOf(value) == -1
String::size                 = (     )-> @.length
String::starts_With          = (value)-> if not value then false else @.toString().slice(0,value.length)==value
String::trim                 = (     )-> @.replace(/^\s+|\s+$/g, '')
String::upper                = (     )-> @.toUpperCase()
