Examples
------------

Textual option:

>>> try:
...     StrOption('str', 'str', 1)
... except ValueError as err:
...     print(err)
...

   * - IPOption
     - An Internet Protocol address (IP address) is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication.

       This option only support version 4 of the Internet Protocol.
     -
       - private_only: restrict to only private IPv4 address
       - allow_reserved: allow the IETF reserved address
       - cidr: Classless Inter-Domain Routing (CIDR) is a method for allocating IP addresses and IP routing, such as 192.168.0.1/24

   * - NetworkOption
     - IP networks may be divided into subnetworks
     -
       - cidr: Classless Inter-Domain Routing (CIDR) is a method for allocating IP addresses and IP routing, such as 192.168.0.0/24

   * - NetmaskOption
     - For IPv4, a network may also be characterized by its subnet mask or netmask. This option allow you to enter a netmask.
     -

   * - BroadcastOption
     - The last address within a network broadcast transmission to all hosts on the link. This option allow you to enter a broadcast:
     -

   * - PortOption
     - A port is a network communication endpoint. It's a string object
     -
       - allow_range: allow is a list of port where we specified first port and last port number with the separator is `:`
       - allow_zero: allow the port 0
       - allow_wellknown: by default, the well-known ports (also known as system ports) those from 1 through 1023 are allowed, you can disabled it
       - allow_registred: by default, the registered ports are those from 1024 through 49151 are allowed, you can disabled it
       - allow_private: allow dynamic or private ports, which are those from 49152 through 65535, one common use for this range is for ephemeral ports

Internet options
==================================

.. list-table:: 
   :widths: 20 40 40
   :header-rows: 1

   * - Type
     - Comments
     - Extra parameters

   * - DomainnameOption
     - Domain names are used in various networking contexts and for application-specific naming and addressing purposes.
     - 
       - type: There is three type for a domain name:

         - "domainname" (default): lowercase, number, "-" and "." characters are allowed, this must have at least one "."
         - "hostname": lowercase, number and "-" characters are allowed, the maximum length is 63 characters
         - "netbios": lowercase, number and "-" characters are allowed, the maximum length is 15 characters

       - allow_ip: the option can contain a domain name or an IP, in this case, IP is validate has IPOption would do.
       - allow_cidr_network: the option can contain a CIDR network
       - allow_without_dot: a domain name with domainname's type must have a dot, if active, we can set a domainname or an hostname
       - allow_startswith_dot: a domain name with domainname's type mustn't start by a dot, .example.net is not a valid domain, in some case it could be interesting to allow domain name starts by a dot (for ACL in Squid, no proxy option in Firefox, ...)

   * - URLOption
     - An Uniform Resource Locator is, in fact, a string starting with http:// or https://, a DomainnameOption, optionaly ':' and a PortOption, and finally filename
     - See PortOption and DomainnameOption parameters

   * - EmailOption
     - Electronic mail (email or e-mail) is a method of exchanging messages ("mail") between people using electronic devices.

Examples
-----------------------------------------------

>>> from tiramisu import DomainnameOption
>>> DomainnameOption('domain', 'domain', 'foo.example.net')
>>> DomainnameOption('domain', 'domain', 'foo', type='hostname')

.. note:: If `warnings_only` parameter it set to True, it will raise if length is incorrect by only emit a warning character is not correct.

>>> from tiramisu import DomainnameOption
>>> DomainnameOption('domain', 'domain', 'foo.example.net', allow_ip=True)

Date option
=============

Date option waits for a date with format YYYY-MM-DD:

Choice option: :class:`ChoiceOption`
======================================

Option that only accepts a list of possible choices.

For example, we just want allowed 1 or 'see later':

>>> from tiramisu import ChoiceOption
>>> ChoiceOption('choice', 'choice', (1, 'see later'), 1)
>>> ChoiceOption('choice', 'choice', (1, 'see later'), 'see later')

Any other value isn't allowed:

>>> try:
...     ChoiceOption('choice', 'choice', (1, 'see later'), "i don't know")
... except ValueError as err:
...     print(err)
... 
"i don't know" is an invalid choice for "choice", only "1" and "see later" are allowed
