"""lorem ipsum generator
In publishing and graphic design, lorem ipsum is a placeholder text commonly
used to demonstrate the visual form of a document or a typeface without
relying on meaningful content.
The :mod:`lorem` module provides a generic access to generating the lorem ipsum
text from its very original text::
Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod
tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim
veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea
commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit
esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat
cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id
est laborum.
Usage of the :mod:`lorem` module is rather simple. Depending on your needs, the
:mod:`lorem` module provides generation of *words*, *sentences*, and
*paragraphs*.
Get Random Words
----------------
The :mod:`lorem` module provides two different ways for getting random words.
1. :func:`word` -- generate a list of random words
.. code-block:: python
word(count=1, func=None, args=(), kwargs={}) -> Iterator[str]
2. :func:`get_word` -- return random words
.. code-block:: python
get_word(count=1, sep=' ', func=None, args=(), kwargs={}) -> str
Get Random Sentences
--------------------
The :mod:`lorem` module provides two different ways for getting random sentences.
1. :func:`sentence` -- generate a list of random sentences
.. code-block:: python
sentence(count=1, comma=(0, 2), word_range=(4, 8)) -> Iterator[str]
2. :func:`get_sentence` -- return random sentences
.. code-block:: python
get_sentence(count=1, sep=' ', comma=(0, 2), word_range=(4, 8)) -> Union[str]
Get Random Paragraphs
---------------------
The :mod:`lorem` module provides two different ways for getting random paragraphs.
1. :func:`paragraph` -- generate a list of random paragraphs
.. code-block:: python
paragraph(count=1, comma=(0, 2), word_range=(4, 8), sentence_range=(5, 10)) -> Iterator[str]
2. :func:`get_paragraph` -- return random paragraphs
.. code-block:: python
get_paragraph(count=1, sep=os.linesep, comma=(0, 2), word_range=(4, 8), sentence_range=(5, 10)) -> Union[str]
