Tables
======

Defining tables
---------------

Tables in Hurdy work the same as in Lua and are defined in the same way:

.. code-block:: hurdy

  var  t = {
    1, 2, 3,
    s = 5,
    [8] = 7,
    ["end"] = true
  }

  -- defines the table with
  -- t[1] = 1
  -- t[2] = 2
  -- t[3] = 3
  -- t[8] = 7
  -- t["s"] = t.s = 5
  -- t["end"] = true

The only difference with Lua is that both commas and newlines can be used as separators
(mixing the two syntaxes is allowed):

.. code-block:: hurdy

  var  t = {
    1
    2
    3
  }

is equivalent to

.. code-block:: hurdy

  var  t = {
    1,
    2,
    3
  }

Trailing commas are allowed and are ignored.

Accessing tables
----------------

Tables (and in general objects with an :code:`__index` metamethod) can be accessed in the same way as Lua:

.. code-block:: hurdy

  t.identifier
  t["identifier"]
  t:identifier() -- can only be used to call a method and is equivalent to t.identifier(t)

.. note::
  Just as in Lua, when accessing a table using the :code:`.` or :code:`:` operator is only possible if
  the identifier is not a Lua reserved keyword. This restriction does not apply to Hurdy-only keywords
  (e.g., :code:`var`).

  .. code-block:: hurdy

    t.end -- not allowed
    t["end"] -- this is ok
    t:global() -- this is ok

  This restriction may be removed in the future.
