| Creates random Latin text useful for providing test data in templates. |
| |
| Usage format:: |
| |
| {% lorem [count] [method] [random] %} |
| |
| ``count`` is a number (or variable) containing the number of paragraphs or |
| words to generate (default is 1). |
| |
| ``method`` is either ``w`` for words, ``p`` for HTML paragraphs, ``b`` for |
| plain-text paragraph blocks (default is ``b``). |
| |
| ``random`` is the word ``random``, which if given, does not use the common |
| paragraph (starting "Lorem ipsum dolor sit amet, consectetuer..."). |
| |
| Examples: |
| * ``{% lorem %}`` will output the common "lorem ipsum" paragraph |
| * ``{% lorem 3 p %}`` will output the common "lorem ipsum" paragraph |
| and two random paragraphs each wrapped in HTML ``<p>`` tags |
| * ``{% lorem 2 w random %}`` will output two random latin words |
