Markdown-To-POD

POD instead of HTML. I hacked it because I want an alternative to
Markdown::Pod 0.005 which is too startup-heavy and has a couple of
annoying bugs, like converting an_identifier and another_identifier to
anI<identifier and another>identifier. The rest of the documentation is
Text::Markdown's.
Markdown is a text-to-HTML filter; it translates an easy-to-read /
easy-to-write structured text format into HTML. Markdown's text format
is most similar to that of plain text email, and supports features such
as headers, *emphasis*, code blocks, blockquotes, and links.
Markdown's syntax is designed not as a generic markup language, but
specifically to serve as a front-end to (X)HTML. You can use span-level
HTML tags anywhere in a Markdown document, and you can use block level
HTML tags (like <div> and <table> as well).
SYNTAX
This module implements the 'original' Markdown markdown syntax from:
http://daringfireball.net/projects/markdown/
Note that Text::Markdown ensures that the output always ends with one
newline. The fact that multiple newlines are collapsed into one makes
sense, because this is the behavior of HTML towards whispace. The fact
that there's always a newline at the end makes sense again, given that
the output will always be nested in a block-level element (as opposed
to an inline element). That block element can be a <p> (most often), or
a <table>.
Markdown is not interpreted in HTML block-level elements, in order for
chunks of pasted HTML (e.g. JavaScript widgets, web counters) to not be
magically (mis)interpreted. For selective processing of Markdown in
some, but not other, HTML block elements, add a markdown attribute to
the block element and set its value to 1, on or yes:
<div markdown="1" class="navbar">
* Home
* About
* Contact
<div>
The extra markdown attribute will be stripped when generating the
output.
OPTIONS
Text::Markdown supports a number of options to its processor which
control the behaviour of the output document.
These options can be supplied to the constructor, or in a hash within
individual calls to the "markdown" method. See the SYNOPSIS for
examples of both styles.
The options for the processor are:
empty_element_suffix
This option controls the end of empty element tags:
'/>' for XHTML (default)
'>' for HTML
tab_width
Controls indent width in the generated markup. Defaults to 4.
trust_list_start_value
If true, ordered lists will use the first number as the starting
point for numbering. This will let you pick up where you left off by
writing:
1. foo
2. bar
some paragraph
3. baz
6. quux
(Note that in the above, quux will be numbered 4.)
METHODS
new
A simple constructor, see the SYNTAX and OPTIONS sections for more
information.
markdown_to_pod
The main function as far as the outside world is concerned. See the
SYNOPSIS for details on use.
urls
Returns a reference to a hash with the key being the markdown reference
and the value being the URL.
Useful for building scripts which preprocess a list of links before the
main content. See t/05options.t for an example of this hashref being
passed back into the markdown method to create links.
OTHER IMPLEMENTATIONS
Markdown has been re-implemented in a number of languages, and with a
number of additions.
Those that I have found are listed below:
C - <http://www.pell.portland.or.us/~orc/Code/discount>
Discount - Original Markdown, but in C. Fastest implementation
available, and passes MDTest. Adds its own set of custom features.
python - <http://www.freewisdom.org/projects/python-markdown/>
Python Markdown which is mostly compatible with the original, with an
interesting extension API.
