From a402d48de37ea6e444bcefbac82c707a058fe440 Mon Sep 17 00:00:00 2001 From: Mike Date: Mon, 3 May 2010 17:15:44 -0700 Subject: [PATCH] New features: * Discount 1.6.1 * Lines beginning with spaces are considered code. I don't know why markdown.py didn't trigger this. * tables in mark down: why not? * validation of resulting HTML vial libxml to prevent hax. * private RSS and JSON feeds * optional whitelists for subreddits * Moderator messaging Additions: * destination sanitization to cut down on XSRF * cosmetic fix to spam and reported listing * make the rss feeds on messages useful * /admin/errors * Of the types of listings hitting the precomputers (top/controversy by hour/day/week/month/year), the ones over long periods of time don't change often. So we can try to run them at most once per day, and then merge in the day's listings. * google analytics * logging queue * Created empty commentspanel.xml, errorpage.xml, login.xml * add subreddit rules/info box to submit page * add 'via' link on messages in moderator inbox * add a show=all get parameter to link listings to optionally ignore hiding preferences. * Raise edited timelimit to three mins * Remove UI that makes it look like you can edit deleted selftexts * Make it clearer to admins when a link is deleted * Fix [S] leak on deleted comments * Fix /user/[deleted] misrendering * New house ads system * updated so that minimalcontrollers actually can use the page cache. * Added /admin/usage Bugfixes: * Reduce the number of results that we request from Solr and simplify that caching a bit * Require a secret key to shut down app-servers * Make get_title a little more resilient to malformed documents and slow remote servers * Cause the SearchBuilder to only byID the results that it's going to render instead of all 1000 * Remove ability for an author to XSS himself * fix spam listings and an xsrf * More verbose VDestination * Fixing the famous ?limit=0.1 error, and one last password-validation one * distinguish deleted comments' and deleted links' error messages * Don't allow ridiculously long log lines to widen the page * Bug with HardCache.add() when existing key is expired * Add adminbox next to domain --- .gitignore | 1 + r2/example.ini | 14 +- r2/r2/config/middleware.py | 7 +- r2/r2/config/routing.py | 72 +- r2/r2/controllers/__init__.py | 5 +-

A Markdown-formatted +document should be publishable as-is, as plain text, without looking +like it's been marked up with tags or formatting instructions. While +Markdown's syntax has been influenced by several existing text-to-HTML +filters -- including +.Em Setext , +.Em atx , +.Em Textile , +.Em reStructuredText , +.Em Grutatext , +and +.Em EtText +\-\- the single biggest source of +inspiration for +Markdown's +syntax is the format of plain text email. +.Pp +To this end, Markdown's syntax is comprised entirely of punctuation +characters, which punctuation characters have been carefully chosen so +as to look like what they mean. E.g., asterisks around a word actually +look like *emphasis*. Markdown lists look like, well, lists. Even +blockquotes look like quoted passages of text, assuming you've ever +used email. +.Ss Inline HTML +Markdown's syntax is intended for one purpose: to be used as a +format for +.Em writing +for the web. +.Pp +.Nm +is not a replacement for HTML, or even close to it. Its +syntax is very small, corresponding only to a very small subset of +HTML tags. The idea is +.Em not +to create a syntax that makes it easier +to insert HTML tags. In my opinion, HTML tags are already easy to +insert. The idea for Markdown is to make it easy to read, write, and +edit prose. HTML is a +.Em publishing +format; Markdown is a +.Em writing +format. Thus, Markdown's formatting syntax only addresses issues that +can be conveyed in plain text. +.Pp +For any markup that is not covered by Markdown's syntax, you simply +use HTML itself. There's no need to preface it or delimit it to +indicate that you're switching from Markdown to HTML; you just use +the tags. +.Pp +The only restrictions are that block-level HTML elements -- e.g. +.Li \
, +.Li \ , +.Li \
 ,
+.Li \
 ,
+etc. -- must be separated from surrounding
+content by blank lines, and the start and end tags of the block should
+not be indented with tabs or spaces. Markdown is smart enough not
+to add extra (unwanted)
+.Li \

+tags around HTML block-level tags.
+.Pp
+For example, to add an HTML table to a Markdown article:
+.Bd -literal -offset indent
+    This is a regular paragraph.
+
+
+ + + +
Foo
+ + This is another regular paragraph. +.Ed +.Pp +Note that Markdown formatting syntax is not processed within block-level +HTML tags. E.g., you can't use Markdown-style +.Li *emphasis* +inside an HTML block. +.Pp +Span-level HTML tags -- e.g. +.Li \ , +.Li \ , +or +.Li \ +\-\- can be +used anywhere in a Markdown paragraph, list item, or header. If you +want, you can even use HTML tags instead of Markdown formatting; e.g. if +you'd prefer to use HTML +.Li \ +or +.Li \ +tags instead of Markdown's +link or image syntax, go right ahead. +.Pp +Unlike block-level HTML tags, Markdown syntax *is* processed within +span-level tags. +.Ss Automatic Escaping for Special Characters +In HTML, there are two characters that demand special treatment: `<` +and `&`. Left angle brackets are used to start tags; ampersands are +used to denote HTML entities. If you want to use them as literal +characters, you must escape them as entities, e.g. `<`, and +`&`. +.Pp +Ampersands in particular are bedeviling for web writers. If you want to +write about 'AT&T', you need to write '`AT&T`'. You even need to +escape ampersands within URLs. Thus, if you want to link to: +.Bd -literal -offset indent + http://images.google.com/images?num=30&q=larry+bird +.Ed +.Pp +you need to encode the URL as: +.Bd -literal -offset indent + http://images.google.com/images?num=30&q=larry+bird +.Ed +.Pp +in your anchor tag `href` attribute. Needless to say, this is easy to +forget, and is probably the single most common source of HTML validation +errors in otherwise well-marked-up web sites. +.Pp +.Nm +allows you to use these characters naturally, taking care of +all the necessary escaping for you. If you use an ampersand as part of +an HTML entity, it remains unchanged; otherwise it will be translated +into `&`. +.Pp +So, if you want to include a copyright symbol in your article, you can write: +.Bd -literal -offset indent + © +.Ed +.Pp +and Markdown will leave it alone. But if you write: +.Bd -literal -offset indent + AT&T +.Ed +.Pp +.Nm +will translate it to: +.Bd -literal -offset indent + AT&T +.Ed +.Pp +Similarly, because Markdown supports inline HTML, if you use +angle brackets as delimiters for HTML tags, Markdown will treat them as +such. But if you write: +.Bd -literal -offset indent + 4 < 5 +.Ed +.Pp +.Nm +will translate it to: +.Bd -literal -offset indent + 4 < 5 +.Ed +.Pp +However, inside Markdown code spans and blocks, angle brackets and +ampersands are *always* encoded automatically. This makes it easy to use +Markdown to write about HTML code. (As opposed to raw HTML, which is a +terrible format for writing about HTML syntax, because every single `<` +and `&` in your example code needs to be escaped.) +.Sh Block Elements +.Ss Paragraphs and Line Breaks +.Pp +A paragraph is simply one or more consecutive lines of text, separated +by one or more blank lines. (A blank line is any line that looks like a +blank line -- a line containing nothing but spaces or tabs is considered +blank.) Normal paragraphs should not be indented with spaces or tabs. +.Pp +The implication of the +.Qq one or more consecutive lines of text +rule is +that Markdown supports +.Qq hard-wrapped +Dtext paragraphs. This differs +significantly from most other text-to-HTML formatters (including Movable +Type's +.Qq Convert Line Breaks +option) which translate every line break +character in a paragraph into a `
` tag. +.Pp +When you *do* want to insert a `
` break tag using Markdown, you +end a line with two or more spaces, then type return. +.Pp +Yes, this takes a tad more effort to create a `
`, but a simplistic +"every line break is a `
`" rule wouldn't work for Markdown. +Markdown's email-style +.Sx blockquoting + and multi-paragraph +.Sx list items +work best -- and look better -- when you format them with hard breaks. +.Ss Headers +.Nm +supports two styles of headers, +.Em Setext +and +.Em atx . +.Pp +Setext-style headers are +.Sq underlined +using equal signs (for first-level +headers) and dashes (for second-level headers). For example: +.Bd -literal -offset indent + This is an H1 + ============= + + This is an H2 + ------------- +.Ed +.Pp +Any number of underlining `=`'s or `-`'s will work. +.Pp +Atx-style headers use 1-6 hash characters at the start of the line, +corresponding to header levels 1-6. For example: +.Bd -literal -offset indent + # This is an H1 + + ## This is an H2 + + ###### This is an H6 +.Ed +.Pp +Optionally, you may +.Qq close +atx-style headers. This is purely +cosmetic -- you can use this if you think it looks better. The +closing hashes don't even need to match the number of hashes +used to open the header. (The number of opening hashes +determines the header level.) : +.Bd -literal -offset indent + # This is an H1 # + + ## This is an H2 ## + + ### This is an H3 ###### +.Ed +.Pp +.Ss Blockquotes +.Nm +uses email-style `>` characters for blockquoting. If you're +familiar with quoting passages of text in an email message, then you +know how to create a blockquote in Markdown. It looks best if you hard +wrap the text and put a `>` before every line: +.Bd -literal -offset indent + > This is a blockquote with two paragraphs. Lorem ipsum + > dolor sit amet, consectetuer adipiscing elit. Aliquam + > hendrerit mi posuere lectus. Vestibulum enim wisi, + > viverra nec, fringilla in, laoreet vitae, risus. + > + > Donec sit amet nisl. Aliquam semper ipsum sit amet + > velit. Suspendisse id sem consectetuer libero luctus + > adipiscing. +.Ed +.Pp +.Nm +allows you to be lazy and only put the `>` before the first +line of a hard-wrapped paragraph: +.Bd -literal -offset indent + > This is a blockquote with two paragraphs. Lorem ipsum + dolor sit amet, consectetuer adipiscing elit. Aliquam + hendrerit mi posuere lectus. Vestibulum enim wisi, + viverra nec, fringilla in, laoreet vitae, risus. + + > Donec sit amet nisl. Aliquam semper ipsum sit amet + velit. Suspendisse id sem consectetuer libero luctus + adipiscing. +.Ed +.Pp +Blockquotes can be nested (i.e. a blockquote-in-a-blockquote) by +adding additional levels of `>`: +.Bd -literal -offset indent + > This is the first level of quoting. + > + > > This is nested blockquote. + > + > Back to the first level. +.Ed +.Pp +Blockquotes can contain other Markdown elements, including headers, lists, +and code blocks: +.Bd -literal -offset indent + > ## This is a header. + > + > 1. This is the first list item. + > 2. This is the second list item. + > + > Here's some example code: + > + > return shell_exec("echo $input | $markdown_script"); +.Ed +.Pp +Any decent text editor should make email-style quoting easy. For +example, with BBEdit, you can make a selection and choose Increase +Quote Level from the Text menu. +.Ss Lists +.Nm +supports ordered (numbered) and unordered (bulleted) lists. +.Pp +Unordered lists use asterisks, pluses, and hyphens -- interchangably +\-- as list markers: +.Bd -literal -offset indent + * Red + * Green + * Blue +.Ed +.Pp +is equivalent to: +.Bd -literal -offset indent + + Red + + Green + + Blue +.Ed +.Pp +and: +.Bd -literal -offset indent + - Red + - Green + - Blue +.Ed +.Pp +Ordered lists use numbers followed by periods: +.Bd -literal -offset indent + 1. Bird + 2. McHale + 3. Parish +.Ed +.Pp +It's important to note that the actual numbers you use to mark the +list have no effect on the HTML output Markdown produces. The HTML +Markdown produces from the above list is: +.Bd -literal -offset indent +
    +
  1. Bird
    2. +
  2. McHale
    3. +
  3. Parish
    4. +
+.Ed +.Pp +If you instead wrote the list in Markdown like this: +.Bd -literal -offset indent + 1. Bird + 1. McHale + 1. Parish +.Ed +.Pp +or even: +.Bd -literal -offset indent + 3. Bird + 1. McHale + 8. Parish +.Ed +.Pp +you'd get the exact same HTML output. The point is, if you want to, +you can use ordinal numbers in your ordered Markdown lists, so that +the numbers in your source match the numbers in your published HTML. +But if you want to be lazy, you don't have to. +.Pp +If you do use lazy list numbering, however, you should still start the +list with the number 1. At some point in the future, Markdown may support +starting ordered lists at an arbitrary number. +.Pp +List markers typically start at the left margin, but may be indented by +up to three spaces. List markers must be followed by one or more spaces +or a tab. +.Pp +To make lists look nice, you can wrap items with hanging indents: +.Bd -literal -offset indent + * Lorem ipsum dolor sit amet, consectetuer adipiscing + elit. Aliquam hendrerit mi posuere lectus. Vestibulum + enim wisi, viverra nec, fringilla in, laoreet vitae, + risus. + * Donec sit amet nisl. Aliquam semper ipsum sit amet + velit. Suspendisse id sem consectetuer libero luctus + adipiscing. +.Ed +.Pp +But if you want to be lazy, you don't have to: +.Bd -literal -offset indent + * Lorem ipsum dolor sit amet, consectetuer adipiscing + elit.

Suspendisse id sem consectetuer libero luctus + adipiscing. +.Ed +.Pp +If list items are separated by blank lines, Markdown will wrap the +items in `

` tags in the HTML output. For example, this input: +.Bd -literal -offset indent + * Bird + * Magic +.Ed +.Pp +will turn into: +.Bd -literal -offset indent +

    +

    +

  • Bird

    • +
+.Ed +.Pp +List items may consist of multiple paragraphs. Each subsequent +paragraph in a list item must be intended by either 4 spaces +or one tab: +.Bd -literal -offset indent + 1. This is a list item with two paragraphs. Lorem ipsum + dolor sit amet, consectetuer adipiscing elit. Aliquam + hendrerit mi posuere lectus. + + Vestibulum enim wisi, viverra nec, fringilla in, + laoreet vitae, risus. Donec sit amet nisl. Aliquam + semper ipsum sit amet velit. + + 2. Suspendisse id sem consectetuer libero luctus + adipiscing. +.Ed +.Pp +It looks nice if you indent every line of the subsequent +paragraphs, but here again, Markdown will allow you to be +lazy: +.Bd -literal -offset indent + * This is a list item with two paragraphs. + + This is the second paragraph in the list item. + You're only required to indent the first line. Lorem + ipsum dolor sit amet, consectetuer adipiscing elit. + + * Another item in the same list. +.Ed +.Pp +To put a blockquote within a list item, the blockquote's `>` +delimiters need to be indented: +.Bd -literal -offset indent + * A list item with a blockquote: + + > This is a blockquote + > inside a list item. +.Ed +.Pp +To put a code block within a list item, the code block needs +to be indented *twice* -- 8 spaces or two tabs: +.Bd -literal -offset indent + * A list item with a code block: + + +.Ed +.Pp +It's worth noting that it's possible to trigger an ordered list by +accident, by writing something like this: +.Bd -literal -offset indent + 1986. What a great season. +.Ed +.Pp +In other words, a *number-period-space* sequence at the beginning of a +line. To avoid this, you can backslash-escape the period: +.Bd -literal -offset indent + 1986\\. What a great season. +.Ed +.Pp +.Ss Code Blocks +Pre-formatted code blocks are used for writing about programming or +markup source code. Rather than forming normal paragraphs, the lines +of a code block are interpreted literally. Markdown wraps a code block +in both `
` and `` tags.
+.Pp
+To produce a code block in Markdown, simply indent every line of the
+block by at least 4 spaces or 1 tab. For example, given this input:
+.Bd -literal -offset indent
+    This is a normal paragraph:
+
+        This is a code block.
+.Ed
+.Pp
+.Nm
+will generate:
+.Bd -literal -offset indent
+    
This is a normal paragraph:

+
+    
This is a code block.
+    

+.Ed
+.Pp
+One level of indentation -- 4 spaces or 1 tab -- is removed from each
+line of the code block. For example, this:
+.Bd -literal -offset indent
+    Here is an example of AppleScript:
+
+        tell application "Foo"
+            beep
+        end tell
+.Ed
+.Pp
+will turn into:
+.Bd -literal -offset indent
+    
Here is an example of AppleScript:

+
+    
tell application "Foo"
+        beep
+    end tell
+    

+.Ed
+.Pp
+A code block continues until it reaches a line that is not indented
+(or the end of the article).
+.Pp
+Within a code block, ampersands (`&`) and angle brackets (`<` and `>`)
+are automatically converted into HTML entities. This makes it very
+easy to include example HTML source code using Markdown -- just paste
+it and indent it, and Markdown will handle the hassle of encoding the
+ampersands and angle brackets. For example, this:
+.Bd -literal -offset indent
+        

+            © 2004 Foo Corporation
+        

+.Ed
+.Pp
+will turn into:
+.Bd -literal -offset indent
+    
<div class="footer">
+        &copy; 2004 Foo Corporation
+    </div>
+    

+.Ed
+.Pp
+Regular Markdown syntax is not processed within code blocks. E.g.,
+asterisks are just literal asterisks within a code block. This means
+it's also easy to use Markdown to write about Markdown's own syntax.
+.Ss Horizontal Rules
+You can produce a horizontal rule tag (`
`) by placing three or
+more hyphens, asterisks, or underscores on a line by themselves. If you
+wish, you may use spaces between the hyphens or asterisks. Each of the
+following lines will produce a horizontal rule:
+.Bd -literal -offset indent
+    * * *
+
+    ***
+
+    *****
+
+    - - -
+
+    ---------------------------------------
+.Ed
+.Pp
+.Sh Span Elements
+.Ss Links
+.Nm
+supports two style of links:
+.Em inline
+and
+.Em reference .
+.Pp
+In both styles, the link text is delimited by [square brackets].
+.Pp
+To create an inline link, use a set of regular parentheses immediately
+after the link text's closing square bracket. Inside the parentheses,
+put the URL where you want the link to point, along with an *optional*
+title for the link, surrounded in quotes. For example:
+.Bd -literal -offset indent
+    This is [an example](http://example.com/ "Title") inline link.
+
+    [This link](http://example.net/) has no title attribute.
+.Ed
+.Pp
+Will produce:
+.Bd -literal -offset indent
+    
This is 
+    an example inline link.

+
+    
This link has no
+    title attribute.

+.Ed
+.Pp
+If you're referring to a local resource on the same server, you can
+use relative paths:
+.Bd -literal -offset indent
+    See my [About](/about/) page for details.   
+.Ed
+.Pp
+Reference-style links use a second set of square brackets, inside
+which you place a label of your choosing to identify the link:
+.Bd -literal -offset indent
+    This is [an example][id] reference-style link.
+.Ed
+.Pp
+You can optionally use a space to separate the sets of brackets:
+.Bd -literal -offset indent
+    This is [an example] [id] reference-style link.
+.Ed
+.Pp
+Then, anywhere in the document, you define your link label like this,
+on a line by itself:
+.Bd -literal -offset indent
+    [id]: http://example.com/  "Optional Title Here"
+.Ed
+.Pp
+That is:
+.Bl -bullet
+.It
+Square brackets containing the link identifier (optionally
+indented from the left margin using up to three spaces);
+.It
+followed by a colon;
+.It
+followed by one or more spaces (or tabs);
+.It
+followed by the URL for the link;
+.It
+optionally followed by a title attribute for the link, enclosed
+in double or single quotes, or enclosed in parentheses.
+.El
+.Pp
+The following three link definitions are equivalent:
+.Bd -literal -offset indent
+	[foo]: http://example.com/  "Optional Title Here"
+	[foo]: http://example.com/  'Optional Title Here'
+	[foo]: http://example.com/  (Optional Title Here)
+.Ed
+.Pp
+.Em Note :
+There is a known bug in Markdown.pl 1.0.1 which prevents
+single quotes from being used to delimit link titles.
+.Pp
+The link URL may, optionally, be surrounded by angle brackets:
+.Bd -literal -offset indent
+    [id]:   "Optional Title Here"
+.Ed
+.Pp
+You can put the title attribute on the next line and use extra spaces
+or tabs for padding, which tends to look better with longer URLs:
+.Bd -literal -offset indent
+    [id]: http://example.com/longish/path/to/resource/here
+        "Optional Title Here"
+.Ed
+.Pp
+Link definitions are only used for creating links during Markdown
+processing, and are stripped from your document in the HTML output.
+.Pp
+Link definition names may constist of letters, numbers, spaces, and
+punctuation -- but they are
+.Em not
+case sensitive. E.g. these two
+links:
+.Bd -literal -offset indent
+	[link text][a]
+	[link text][A]
+.Ed
+.Pp
+are equivalent.
+.Pp
+The
+.Em implicit link name
+shortcut allows you to omit the name of the
+link, in which case the link text itself is used as the name.
+Just use an empty set of square brackets -- e.g., to link the word
+.Qq Google
+to the google.com web site, you could simply write:
+.Bd -literal -offset indent
+	[Google][]
+.Ed
+.Pp
+And then define the link:
+.Bd -literal -offset indent
+	[Google]: http://google.com/
+.Ed
+.Pp
+Because link names may contain spaces, this shortcut even works for
+multiple words in the link text:
+.Bd -literal -offset indent
+	Visit [Daring Fireball][] for more information.
+.Ed
+.Pp
+And then define the link:
+.Bd -literal -offset indent
+	[Daring Fireball]: http://daringfireball.net/
+.Ed
+.Pp
+Link definitions can be placed anywhere in your Markdown document. I
+tend to put them immediately after each paragraph in which they're
+used, but if you want, you can put them all at the end of your
+document, sort of like footnotes.
+.Pp
+Here's an example of reference links in action:
+.Bd -literal -offset indent
+    I get 10 times more traffic from [Google] [1] than from
+    [Yahoo] [2] or [MSN] [3].
+
+      [1]: http://google.com/        "Google"
+      [2]: http://search.yahoo.com/  "Yahoo Search"
+      [3]: http://search.msn.com/    "MSN Search"
+.Ed
+.Pp
+Using the implicit link name shortcut, you could instead write:
+.Bd -literal -offset indent
+    I get 10 times more traffic from [Google][] than from
+    [Yahoo][] or [MSN][].
+
+      [google]: http://google.com/        "Google"
+      [yahoo]:  http://search.yahoo.com/  "Yahoo Search"
+      [msn]:    http://search.msn.com/    "MSN Search"
+.Ed
+.Pp
+Both of the above examples will produce the following HTML output:
+.Bd -literal -offset indent
+    
I get 10 times more traffic from Google than from
+    Yahoo
+    or
+    MSN.

+.Ed
+.Pp
+For comparison, here is the same paragraph written using
+Markdown's inline link style:
+.Bd -literal -offset indent
+    I get 10 times more traffic from
+    [Google](http://google.com/ "Google") than from
+    [Yahoo](http://search.yahoo.com/ "Yahoo Search") or
+    [MSN](http://search.msn.com/ "MSN Search").
+.Ed
+.Pp
+The point of reference-style links is not that they're easier to
+write. The point is that with reference-style links, your document
+source is vastly more readable. Compare the above examples: using
+reference-style links, the paragraph itself is only 81 characters
+long; with inline-style links, it's 176 characters; and as raw HTML,
+it's 234 characters. In the raw HTML, there's more markup than there
+is text.
+.Pp
+With Markdown's reference-style links, a source document much more
+closely resembles the final output, as rendered in a browser. By
+allowing you to move the markup-related metadata out of the paragraph,
+you can add links without interrupting the narrative flow of your
+prose.
+.Ss Emphasis
+Markdown treats asterisks (`*`) and underscores (`_`) as indicators of
+emphasis. Text wrapped with one `*` or `_` will be wrapped with an
+HTML `` tag; double `*`'s or `_`'s will be wrapped with an HTML
+`` tag. E.g., this input:
+.Bd -literal -offset indent
+    *single asterisks*
+
+    _single underscores_
+
+    **double asterisks**
+
+    __double underscores__
+.Ed
+.Pp
+will produce:
+.Bd -literal -offset indent
+    single asterisks
+
+    single underscores
+
+    double asterisks
+
+    double underscores
+.Ed
+.Pp
+You can use whichever style you prefer; the lone restriction is that
+the same character must be used to open and close an emphasis span.
+.Pp
+Emphasis can be used in the middle of a word:
+.Bd -literal -offset indent
+    un*fucking*believable
+.Ed
+.Pp
+But if you surround an `*` or `_` with spaces, it'll be treated as a
+literal asterisk or underscore.
+.Pp
+To produce a literal asterisk or underscore at a position where it
+would otherwise be used as an emphasis delimiter, you can backslash
+escape it:
+.Bd -literal -offset indent
+    \\*this text is surrounded by literal asterisks\\*
+.Ed
+.Pp
+.Ss Code
+To indicate a span of code, wrap it with backtick quotes (`` ` ``).
+Unlike a pre-formatted code block, a code span indicates code within a
+normal paragraph. For example:
+.Bd -literal -offset indent
+    Use the `printf()` function.
+.Ed
+.Pp
+will produce:
+.Bd -literal -offset indent
+    
Use the printf() function.

+.Ed
+.Pp
+To include a literal backtick character within a code span, you can use
+multiple backticks as the opening and closing delimiters:
+.Bd -literal -offset indent
+    ``There is a literal backtick (`) here.``
+.Ed
+.Pp
+which will produce this:
+.Bd -literal -offset indent
+    
There is a literal backtick (`) here.

+.Ed
+.Pp
+The backtick delimiters surrounding a code span may include spaces --
+one after the opening, one before the closing. This allows you to place
+literal backtick characters at the beginning or end of a code span:
+.Bd -literal -offset indent
+	A single backtick in a code span: `` ` ``
+	
+	A backtick-delimited string in a code span: `` `foo` ``
+.Ed
+.Pp
+will produce:
+.Bd -literal -offset indent
+	
A single backtick in a code span: `

+	
+	
A backtick-delimited string in a code span: `foo`

+.Ed
+.Pp
+With a code span, ampersands and angle brackets are encoded as HTML
+entities automatically, which makes it easy to include example HTML
+tags. Markdown will turn this:
+.Bd -literal -offset indent
+    Please don't use any `` tags.
+.Ed
+.Pp
+into:
+.Bd -literal -offset indent
+    
Please don't use any <blink> tags.

+.Ed
+.Pp
+You can write this:
+.Bd -literal -offset indent
+    `—` is the decimal-encoded equivalent of `—`.
+.Ed
+.Pp
+to produce:
+.Bd -literal -offset indent
+    
&#8212; is the decimal-encoded
+    equivalent of &mdash;.

+.Ed
+.Pp
+.Ss Images
+Admittedly, it's fairly difficult to devise a
+.Qq natural
+syntax for placing images into a plain text document format.
+.Pp
+Markdown uses an image syntax that is intended to resemble the syntax
+for links, allowing for two styles:
+.Em inline
+and
+.Em reference .
+.Pp
+Inline image syntax looks like this:
+.Bd -literal -offset indent
+    ![Alt text](/path/to/img.jpg)
+
+    ![Alt text](/path/to/img.jpg =Optional size "Optional title")
+.Ed
+.Pp
+That is:
+.Bl -bullet
+.It
+An exclamation mark: `!`;
+.It
+followed by a set of square brackets, containing the `alt`
+attribute text for the image;
+.It
+followed by a set of parentheses, containing the URL or path to
+the image, an optional `size` attribute (in
+.Ar width Li c Ar height
+format) prefixed with a `=`,
+and an optional `title` attribute enclosed in double
+or single quotes.
+.El
+.Pp
+Reference-style image syntax looks like this:
+.Bd -literal -offset indent
+    ![Alt text][id]
+.Ed
+.Pp
+Where
+.Qq id
+is the name of a defined image reference. Image references
+are defined using syntax identical to link references:
+.Bd -literal -offset indent
+    [id]: url/to/image  =Optional size "Optional title attribute"
+.Ed
+.Pp
+.Sh Miscellaneous
+.Ss Automatic Links
+.Nm
+supports a shortcut style for creating
+.Qq automatic
+links for URLs and email addresses: simply surround the URL or email
+address with angle brackets. What this means is that if you want to
+ show the actual text of a URL or email address, and also have it be
+  a clickable link, you can do this:
+.Bd -literal -offset indent
+    
+.Ed
+.Pp
+.Nm
+will turn this into:
+.Bd -literal -offset indent
+    http://example.com/
+.Ed
+.Pp
+Automatic links for email addresses work similarly, except that
+Markdown will also perform a bit of randomized decimal and hex
+entity-encoding to help obscure your address from address-harvesting
+spambots. For example, Markdown will turn this:
+.Bd -literal -offset indent
+    
+.Ed
+.Pp
+into something like this:
+.Bd -literal -offset indent
+    address@exa
+    mple.com
+.Ed
+.Pp
+which will render in a browser as a clickable link to
+.Qq address@example.com .
+.Pp
+(This sort of entity-encoding trick will indeed fool many, if not
+most, address-harvesting bots, but it definitely won't fool all of
+them. It's better than nothing, but an address published in this way
+will probably eventually start receiving spam.)
+.Ss Backslash Escapes
+.Nm
+allows you to use backslash escapes to generate literal
+characters which would otherwise have special meaning in Markdown's
+formatting syntax. For example, if you wanted to surround a word with
+literal asterisks (instead of an HTML `` tag), you add backslashes
+before the asterisks, like this:
+.Bd -literal -offset indent
+    \\*literal asterisks\\*
+.Ed
+.Pp
+.Nm
+provides backslash escapes for the following characters:
+.Bl -tag -compact
+.It \&\
+backslash
+.It \`
+backtick
+.It *
+asterisk
+.It _
+underscore
+.It \{\}
+curly braces
+.It []
+square brackets
+.It ()
+parentheses
+.It #
+hash mark
+.It +
+plus sign
+.It \-
+minus sign (hyphen)
+.It \.
+dot
+.It \!
+exclamation mark
+.El
+.Sh BUGS
+.Nm
+assumes that tabs are set to 4 spaces.

+.Dt MKD-EXTENSIONS 7
+.Os MASTODON
+.Sh NAME
+.Nm mkd-extensions
+.Nd Extensions to the Markdown text formatting syntax
+.Sh DESCRIPTION
+This version of markdown has been extended in a few ways by
+extending existing markup, creating new markup from scratch,
+and borrowing markup from other markup languages.
+.Ss Image dimensions
+Markdown embedded images have been extended to allow specifying
+the dimensions of the image by adding a new argument
+.Em =/height/x/width/
+to the link description.
+.Pp
+The new image syntax is
+.nf
+	![alt text](image =/height/x/width/ "title")
+.fi
+.Ss pseudo-protocols
+Three pseudo-protocols have been added to links
+.Bl -tag -width XXXXX
+.It Ar id:
+The 
+.Ar "alt text"
+is marked up and written to the output, wrapped with
+.Em ""
+and
+.Em "" .
+.It Ar class:
+The
+.Ar "alt text"
+is marked up and written to the output, wrapped with
+.Em ""
+and
+.Em "" .
+.It Ar raw:
+The
+.Ar title
+is written
+.Em -- with no further processing --
+to the output.  The 
+.Ar "alt text"
+is discarded.
+.It Ar abbr:
+The
+.Ar "alt text"
+is marked up and written to the output, wrapped with
+.Em "
+and
+.Em "" .
+.El
+.Ss Pandoc headers
+If markdown was configured with
+.Ar --enable-pandoc-header ,
+the markdown source document can have a 3-line 
+.Xr Pandoc
+header in the format of
+.nf
+    % title
+    % author(s)
+    % date
+.fi
+which will be made available to the
+.Fn mkd_doc_title ,
+.Fn mkd_doc_author ,
+and
+.Fn mkd_doc_date
+functions.
+.Ss Definition lists
+If markdown was configured with
+.Ar --enable-dl-tag ,
+markup for definition lists is enabled.  A definition list item
+is defined as
+.nf
+=tag=
+    description
+.fi
+(that is a
+.Ar = ,
+followed by text, another
+.Ar = ,
+a newline, 4 spaces of intent, and then more text.)
+.Pp
+.Ss embedded stylesheets
+Stylesheets may be defined and modified in a
+.Em 
+at the end of the line or a
+.Em 
+at the beginning of a subsequent line.
+.Pp
+Be warned that style blocks work like footnote links -- no matter
+where you define them they are valid for the entire document.
+.Ss relaxed emphasis
+If markdown was configured with
+.Ar --relaxed-emphasis ,
+the rules for emphasis are changed so that a single
+.Ar _
+will
+.Em not
+count as a emphasis character if it's in the middle of a word.
+This is primarily for documenting code, if you don't wish to
+have to backquote all code references.
+.Ss alpha lists
+If markdown was configured with
+.Ar --enable-alpha-list ,
+alphabetic lists (like regular numeric lists, but with alphabetic
+items) are supported.    So:
+.nf
+    a. this
+    b. is
+    c. an alphabetic
+    d. list
+.fi
+will produce:
+.nf
+    
    
+    
  1. this
    2. 
+    
  2. is
    3. 
+    
  3. an alphabetic
    4. 
+    
  4. list
    5. 
+    

+.fi
+.Ss tables
+.Ar PHP Markdown Extra -style
+tables are supported;  input of the form
+.nf
+    header|header
+    ------|------
+     text | text
+.fi
+will produce:
+.nf
+    
+    
+    
+    
+    
+    
+    
+    
+    
+    
+    
+    
+    
+    
headerheader
texttext

+.fi
+The dashed line can also contain
+.Em :
+characters for formatting;  if a 
+.Em :
+is at the start of a column, it tells
+.Nm discount
+to align the cell contents to the left;  if it's at the end, it
+aligns right, and if there's one at the start and at the
+end, it centers.

+.Pp
+The

+format supported in this implementation includes
+Pandoc-style header and inline 
+.Ar \
+blocks, and the standard
+.Xr markdown 3
+functions do not provide access to
+the data provided by either of those extensions.
+These functions give you access to that data, plus
+they provide a finer-grained way of converting
+.Em Markdown 
+documents into HTML.
+.Pp
+Given a
+.Ar MMIOT*
+generated by
+.Fn mkd_in
+or
+.Fn mkd_string ,
+.Fn mkd_compile
+compiles the document into
+.Em \ ,
+.Em Pandoc ,
+and
+.Em html
+sections.
+.Pp
+Once compiled, the document can be examined and written
+by the
+.Fn mkd_css ,
+.Fn mkd_document ,
+.Fn mkd_generatecss ,
+.Fn mkd_generatehtml ,
+.Fn mkd_generatetoc ,
+.Fn mkd_toc ,
+.Fn mkd_xhtmlpage ,
+.Fn mkd_doc_title ,
+.Fn mkd_doc_author ,
+and
+.Fn mkd_doc_date
+functions.
+.Pp
+.Fn mkd_css
+allocates a string and populates it with any \ sections
+provided in the document,
+.Fn mkd_generatecss
+writes any \ sections to the output,
+.Fn mkd_document
+points
+.Ar text
+to the text of the document and returns the
+size of the document,
+.Fn mkd_generatehtml
+writes the rest of the document to the output,
+and 
+.Fn mkd_doc_title ,
+.Fn mkd_doc_author ,
+.Fn mkd_doc_date
+are used to read the contents of a Pandoc header,
+if any.
+.Pp
+.Fn mkd_xhtmlpage
+writes a xhtml page containing the document.  The regular set of
+flags can be passed.
+.Pp
+.Fn mkd_toc
+writes a document outline, in the form of a collection of nested
+lists with links to each header in the document, into a string
+allocated with
+.Fn malloc ,
+and returns the size.
+.Pp
+.Fn mkd_generatetoc
+is like
+.Fn mkd_toc ,
+except that it writes the document outline to the given
+.Pa FILE*
+argument.
+.Pp
+.Fn mkd_cleanup
+deletes a
+.Ar MMIOT*
+after processing is done.
+.Pp
+.Fn mkd_compile
+accepts the same flags that
+.Fn markdown
+and
+.Fn mkd_string
+do; 
+.Bl -tag -width MKD_NOIMAGE -compact
+.It Ar MKD_NOIMAGE
+Do not process `![]' and

+Do not process `[]' and remove
+.Em \
+tags from the output.
+.It Ar MKD_NOPANTS
+Do not do Smartypants-style mangling of quotes, dashes, or ellipses.
+.It Ar MKD_TAGTEXT
+Process the input as if you were inside a html tag.  This means that
+no html tags will be generated, and 
+.Fn mkd_compile
+will attempt to escape anything that might terribly confuse a 
+web browser.
+.It Ar MKD_NO_EXT
+Do not process any markdown pseudo-protocols when
+handing
+.Ar [][]
+links.
+.It Ar MKD_NOHEADER
+Do not attempt to parse any Pandoc-style headers.
+.It Ar MKD_TOC
+Label all headers for use with the
+.Fn mkd_generatetoc
+function.
+.It Ar MKD_1_COMPAT
+MarkdownTest_1.0 compatability flag; trim trailing spaces from the
+first line of code blocks and disable implicit reference links.

+
+
Overview

+
+
Philosophy

+
+Markdown is intended to be as easy-to-read and easy-to-write as is feasible.
+
+Readability, however, is emphasized above all else. A Markdown-formatted
+document should be publishable as-is, as plain text, without looking
+like it's been marked up with tags or formatting instructions. While
+Markdown's syntax has been influenced by several existing text-to-HTML
+filters -- including [Setext] [1], [atx] [2], [Textile] [3], [reStructuredText] [4],
+[Grutatext] [5], and [EtText] [6] -- the single biggest source of
+inspiration for Markdown's syntax is the format of plain text email.
+
+  [1]: http://docutils.sourceforge.net/mirror/setext.html
+  [2]: http://www.aaronsw.com/2002/atx/
+  [3]: http://textism.com/tools/textile/
+  [4]: http://docutils.sourceforge.net/rst.html
+  [5]: http://www.triptico.com/software/grutatxt.html
+  [6]: http://ettext.taint.org/doc/
+
+To this end, Markdown's syntax is comprised entirely of punctuation
+characters, which punctuation characters have been carefully chosen so
+as to look like what they mean. E.g., asterisks around a word actually
+look like \*emphasis\*. Markdown lists look like, well, lists. Even
+blockquotes look like quoted passages of text, assuming you've ever
+used email.
+
+
+
+
Inline HTML

+
+Markdown's syntax is intended for one purpose: to be used as a
+format for *writing* for the web.
+
+Markdown is not a replacement for HTML, or even close to it. Its
+syntax is very small, corresponding only to a very small subset of
+HTML tags. The idea is *not* to create a syntax that makes it easier
+to insert HTML tags. In my opinion, HTML tags are already easy to
+insert. The idea for Markdown is to make it easy to read, write, and
+edit prose. HTML is a *publishing* format; Markdown is a *writing*
+format. Thus, Markdown's formatting syntax only addresses issues that
+can be conveyed in plain text.
+
+For any markup that is not covered by Markdown's syntax, you simply
+use HTML itself. There's no need to preface it or delimit it to
+indicate that you're switching from Markdown to HTML; you just use
+the tags.
+
+The only restrictions are that block-level HTML elements -- e.g. `
`,
+`
`, `
`, `
`, etc. -- must be separated from surrounding
+content by blank lines, and the start and end tags of the block should
+not be indented with tabs or spaces. Markdown is smart enough not
+to add extra (unwanted) `
` tags around HTML block-level tags.
+
+For example, to add an HTML table to a Markdown article:
+
+    This is a regular paragraph.
+
+    

+        
+            
+        
+    
Foo

+
+    This is another regular paragraph.
+
+Note that Markdown formatting syntax is not processed within block-level
+HTML tags. E.g., you can't use Markdown-style `*emphasis*` inside an
+HTML block.
+
+Span-level HTML tags -- e.g. ``, ``, or `` -- can be
+used anywhere in a Markdown paragraph, list item, or header. If you
+want, you can even use HTML tags instead of Markdown formatting; e.g. if
+you'd prefer to use HTML `` or `` tags instead of Markdown's
+link or image syntax, go right ahead.
+
+Unlike block-level HTML tags, Markdown syntax *is* processed within
+span-level tags.
+
+
+
Automatic Escaping for Special Characters

+
+In HTML, there are two characters that demand special treatment: `<`
+and `&`. Left angle brackets are used to start tags; ampersands are
+used to denote HTML entities. If you want to use them as literal
+characters, you must escape them as entities, e.g. `<`, and
+`&`.
+
+Ampersands in particular are bedeviling for web writers. If you want to
+write about 'AT&T', you need to write '`AT&T`'. You even need to
+escape ampersands within URLs. Thus, if you want to link to:
+
+    http://images.google.com/images?num=30&q=larry+bird
+
+you need to encode the URL as:
+
+    http://images.google.com/images?num=30&q=larry+bird
+
+in your anchor tag `href` attribute. Needless to say, this is easy to
+forget, and is probably the single most common source of HTML validation
+errors in otherwise well-marked-up web sites.
+
+Markdown allows you to use these characters naturally, taking care of
+all the necessary escaping for you. If you use an ampersand as part of
+an HTML entity, it remains unchanged; otherwise it will be translated
+into `&`.
+
+So, if you want to include a copyright symbol in your article, you can write:
+
+    ©
+
+and Markdown will leave it alone. But if you write:
+
+    AT&T
+
+Markdown will translate it to:
+
+    AT&T
+
+Similarly, because Markdown supports [inline HTML](#html), if you use
+angle brackets as delimiters for HTML tags, Markdown will treat them as
+such. But if you write:
+
+    4 < 5
+
+Markdown will translate it to:
+
+    4 < 5
+
+However, inside Markdown code spans and blocks, angle brackets and
+ampersands are *always* encoded automatically. This makes it easy to use
+Markdown to write about HTML code. (As opposed to raw HTML, which is a
+terrible format for writing about HTML syntax, because every single `<`
+and `&` in your example code needs to be escaped.)
+
+
+* * *
+
+
+
Block Elements

+
+
+
Paragraphs and Line Breaks

+
+A paragraph is simply one or more consecutive lines of text, separated
+by one or more blank lines. (A blank line is any line that looks like a
+blank line -- a line containing nothing but spaces or tabs is considered
+blank.) Normal paragraphs should not be indented with spaces or tabs.
+
+The implication of the "one or more consecutive lines of text" rule is
+that Markdown supports "hard-wrapped" text paragraphs. This differs
+significantly from most other text-to-HTML formatters (including Movable
+Type's "Convert Line Breaks" option) which translate every line break
+character in a paragraph into a `
` tag.
+
+When you *do* want to insert a `
` break tag using Markdown, you
+end a line with two or more spaces, then type return.
+
+Yes, this takes a tad more effort to create a `
`, but a simplistic
+"every line break is a `
`" rule wouldn't work for Markdown.
+Markdown's email-style [blockquoting][bq] and multi-paragraph [list items][l]
+work best -- and look better -- when you format them with hard breaks.
+
+  [bq]: #blockquote
+  [l]:  #list
+
+
+
+
+
+Markdown supports two styles of headers, [Setext] [1] and [atx] [2].
+
+Setext-style headers are "underlined" using equal signs (for first-level
+headers) and dashes (for second-level headers). For example:
+
+    This is an H1
+    =============
+
+    This is an H2
+    -------------
+
+Any number of underlining `=`'s or `-`'s will work.
+
+Atx-style headers use 1-6 hash characters at the start of the line,
+corresponding to header levels 1-6. For example:
+
+    # This is an H1
+
+    ## This is an H2
+
+    ###### This is an H6
+
+Optionally, you may "close" atx-style headers. This is purely
+cosmetic -- you can use this if you think it looks better. The
+closing hashes don't even need to match the number of hashes
+used to open the header. (The number of opening hashes
+determines the header level.) :
+
+    # This is an H1 #
+
+    ## This is an H2 ##
+
+    ### This is an H3 ######
+
+
+
Blockquotes

+
+Markdown uses email-style `>` characters for blockquoting. If you're
+familiar with quoting passages of text in an email message, then you
+know how to create a blockquote in Markdown. It looks best if you hard
+wrap the text and put a `>` before every line:
+
+    > This is a blockquote with two paragraphs. Lorem ipsum dolor sit amet,
+    > consectetuer adipiscing elit. Aliquam hendrerit mi posuere lectus.
+    > Vestibulum enim wisi, viverra nec, fringilla in, laoreet vitae, risus.
+    > 
+    > Donec sit amet nisl. Aliquam semper ipsum sit amet velit. Suspendisse
+    > id sem consectetuer libero luctus adipiscing.
+
+Markdown allows you to be lazy and only put the `>` before the first
+line of a hard-wrapped paragraph:
+
+    > This is a blockquote with two paragraphs. Lorem ipsum dolor sit amet,
+    consectetuer adipiscing elit. Aliquam hendrerit mi posuere lectus.
+    Vestibulum enim wisi, viverra nec, fringilla in, laoreet vitae, risus.
+
+    > Donec sit amet nisl. Aliquam semper ipsum sit amet velit. Suspendisse
+    id sem consectetuer libero luctus adipiscing.
+
+Blockquotes can be nested (i.e. a blockquote-in-a-blockquote) by
+adding additional levels of `>`:
+
+    > This is the first level of quoting.
+    >
+    > > This is nested blockquote.
+    >
+    > Back to the first level.
+
+Blockquotes can contain other Markdown elements, including headers, lists,
+and code blocks:
+
+	> ## This is a header.
+	> 
+	> 1.   This is the first list item.
+	> 2.   This is the second list item.
+	> 
+	> Here's some example code:
+	> 
+	>     return shell_exec("echo $input | $markdown_script");
+
+Any decent text editor should make email-style quoting easy. For
+example, with BBEdit, you can make a selection and choose Increase
+Quote Level from the Text menu.
+
+
+
Lists

+
+Markdown supports ordered (numbered) and unordered (bulleted) lists.
+
+Unordered lists use asterisks, pluses, and hyphens -- interchangably
+-- as list markers:
+
+    *   Red
+    *   Green
+    *   Blue
+
+is equivalent to:
+
+    +   Red
+    +   Green
+    +   Blue
+
+and:
+
+    -   Red
+    -   Green
+    -   Blue
+
+Ordered lists use numbers followed by periods:
+
+    1.  Bird
+    2.  McHale
+    3.  Parish
+
+It's important to note that the actual numbers you use to mark the
+list have no effect on the HTML output Markdown produces. The HTML
+Markdown produces from the above list is:
+
+    
    
+    
  1. Bird
    2. 
+    
  2. McHale
    3. 
+    
  3. Parish
    4. 
+    

+
+If you instead wrote the list in Markdown like this:
+
+    1.  Bird
+    1.  McHale
+    1.  Parish
+
+or even:
+
+    3. Bird
+    1. McHale
+    8. Parish
+
+you'd get the exact same HTML output. The point is, if you want to,
+you can use ordinal numbers in your ordered Markdown lists, so that
+the numbers in your source match the numbers in your published HTML.
+But if you want to be lazy, you don't have to.
+
+If you do use lazy list numbering, however, you should still start the
+list with the number 1. At some point in the future, Markdown may support
+starting ordered lists at an arbitrary number.
+
+List markers typically start at the left margin, but may be indented by
+up to three spaces. List markers must be followed by one or more spaces
+or a tab.
+
+To make lists look nice, you can wrap items with hanging indents:
+
+    *   Lorem ipsum dolor sit amet, consectetuer adipiscing elit.
+        Aliquam hendrerit mi posuere lectus. Vestibulum enim wisi,
+        viverra nec, fringilla in, laoreet vitae, risus.
+    *   Donec sit amet nisl. Aliquam semper ipsum sit amet velit.
+        Suspendisse id sem consectetuer libero luctus adipiscing.
+
+But if you want to be lazy, you don't have to:
+
+    *   Lorem ipsum dolor sit amet, consectetuer adipiscing elit.
+    Aliquam hendrerit mi posuere lectus. Vestibulum enim wisi,
+    viverra nec, fringilla in, laoreet vitae, risus.
+    *   Donec sit amet nisl. Aliquam semper ipsum sit amet velit.
+    Suspendisse id sem consectetuer libero luctus adipiscing.
+
+If list items are separated by blank lines, Markdown will wrap the
+items in `
` tags in the HTML output. For example, this input:
+
+    *   Bird
+    *   Magic
+
+will turn into:
+
+    
    
+    
  • Bird
    • 
+    
  • Magic
    • 
+    

+
+But this:
+
+    *   Bird
+
+    *   Magic
+
+will turn into:
+
+    
    
+    
  • Bird
    • 
+    
  • Magic
    • 
+    

+
+List items may consist of multiple paragraphs. Each subsequent
+paragraph in a list item must be intended by either 4 spaces
+or one tab:
+
+    1.  This is a list item with two paragraphs. Lorem ipsum dolor
+        sit amet, consectetuer adipiscing elit. Aliquam hendrerit
+        mi posuere lectus.
+
+        Vestibulum enim wisi, viverra nec, fringilla in, laoreet
+        vitae, risus. Donec sit amet nisl. Aliquam semper ipsum
+        sit amet velit.
+
+    2.  Suspendisse id sem consectetuer libero luctus adipiscing.
+
+It looks nice if you indent every line of the subsequent
+paragraphs, but here again, Markdown will allow you to be
+lazy:
+
+    *   This is a list item with two paragraphs.
+
+        This is the second paragraph in the list item. You're
+    only required to indent the first line. Lorem ipsum dolor
+    sit amet, consectetuer adipiscing elit.
+
+    *   Another item in the same list.
+
+To put a blockquote within a list item, the blockquote's `>`
+delimiters need to be indented:
+
+    *   A list item with a blockquote:
+
+        > This is a blockquote
+        > inside a list item.
+
+To put a code block within a list item, the code block needs
+to be indented *twice* -- 8 spaces or two tabs:
+
+    *   A list item with a code block:
+
+            
+
+
+It's worth noting that it's possible to trigger an ordered list by
+accident, by writing something like this:
+
+    1986. What a great season.
+
+In other words, a *number-period-space* sequence at the beginning of a
+line. To avoid this, you can backslash-escape the period:
+
+    1986\. What a great season.
+
+
+
+
Code Blocks

+
+Pre-formatted code blocks are used for writing about programming or
+markup source code. Rather than forming normal paragraphs, the lines
+of a code block are interpreted literally. Markdown wraps a code block
+in both `
` and `` tags.
+
+To produce a code block in Markdown, simply indent every line of the
+block by at least 4 spaces or 1 tab. For example, given this input:
+
+    This is a normal paragraph:
+
+        This is a code block.
+
+Markdown will generate:
+
+    
This is a normal paragraph:

+
+    
This is a code block.
+    

+
+One level of indentation -- 4 spaces or 1 tab -- is removed from each
+line of the code block. For example, this:
+
+    Here is an example of AppleScript:
+
+        tell application "Foo"
+            beep
+        end tell
+
+will turn into:
+
+    
Here is an example of AppleScript:

+
+    
tell application "Foo"
+        beep
+    end tell
+    

+
+A code block continues until it reaches a line that is not indented
+(or the end of the article).
+
+Within a code block, ampersands (`&`) and angle brackets (`<` and `>`)
+are automatically converted into HTML entities. This makes it very
+easy to include example HTML source code using Markdown -- just paste
+it and indent it, and Markdown will handle the hassle of encoding the
+ampersands and angle brackets. For example, this:
+
+        

+            © 2004 Foo Corporation
+        

+
+will turn into:
+
+    
<div class="footer">
+        &copy; 2004 Foo Corporation
+    </div>
+    

+
+Regular Markdown syntax is not processed within code blocks. E.g.,
+asterisks are just literal asterisks within a code block. This means
+it's also easy to use Markdown to write about Markdown's own syntax.
+
+
+
+
Horizontal Rules

+
+You can produce a horizontal rule tag (`
`) by placing three or
+more hyphens, asterisks, or underscores on a line by themselves. If you
+wish, you may use spaces between the hyphens or asterisks. Each of the
+following lines will produce a horizontal rule:
+
+    * * *
+
+    ***
+
+    *****

Span Elements

+
+
+
+Markdown supports two style of links: *inline* and *reference*.
+
+In both styles, the link text is delimited by [square brackets].
+
+To create an inline link, use a set of regular parentheses immediately
+after the link text's closing square bracket. Inside the parentheses,
+put the URL where you want the link to point, along with an *optional*
+title for the link, surrounded in quotes. For example:
+
+    This is [an example](http://example.com/ "Title") inline link.
+
+    [This link](http://example.net/) has no title attribute.
+
+Will produce:
+
+    
This is 
+    an example inline link.

+
+    
This link has no
+    title attribute.

+
+If you're referring to a local resource on the same server, you can
+use relative paths:
+
+    See my [About](/about/) page for details.   
+
+Reference-style links use a second set of square brackets, inside
+which you place a label of your choosing to identify the link:
+
+    This is [an example][id] reference-style link.
+
+You can optionally use a space to separate the sets of brackets:
+
+    This is [an example] [id] reference-style link.
+
+Then, anywhere in the document, you define your link label like this,
+on a line by itself:
+
+    [id]: http://example.com/  "Optional Title Here"
+
+That is:
+
+*   Square brackets containing the link identifier (optionally
+    indented from the left margin using up to three spaces);
+*   followed by a colon;
+*   followed by one or more spaces (or tabs);
+*   followed by the URL for the link;
+*   optionally followed by a title attribute for the link, enclosed
+    in double or single quotes, or enclosed in parentheses.
+
+The following three link definitions are equivalent:
+
+	[foo]: http://example.com/  "Optional Title Here"
+	[foo]: http://example.com/  'Optional Title Here'
+	[foo]: http://example.com/  (Optional Title Here)
+
+**Note:** There is a known bug in Markdown.pl 1.0.1 which prevents
+single quotes from being used to delimit link titles.
+
+The link URL may, optionally, be surrounded by angle brackets:
+
+    [id]:   "Optional Title Here"
+
+You can put the title attribute on the next line and use extra spaces
+or tabs for padding, which tends to look better with longer URLs:
+
+    [id]: http://example.com/longish/path/to/resource/here
+        "Optional Title Here"
+
+Link definitions are only used for creating links during Markdown
+processing, and are stripped from your document in the HTML output.
+
+Link definition names may constist of letters, numbers, spaces, and
+punctuation -- but they are *not* case sensitive. E.g. these two
+links:
+
+	[link text][a]
+	[link text][A]
+
+are equivalent.
+
+The *implicit link name* shortcut allows you to omit the name of the
+link, in which case the link text itself is used as the name.
+Just use an empty set of square brackets -- e.g., to link the word
+"Google" to the google.com web site, you could simply write:
+
+	[Google][]
+
+And then define the link:
+
+	[Google]: http://google.com/
+
+Because link names may contain spaces, this shortcut even works for
+multiple words in the link text:
+
+	Visit [Daring Fireball][] for more information.
+
+And then define the link:
+	
+	[Daring Fireball]: http://daringfireball.net/
+
+Link definitions can be placed anywhere in your Markdown document. I
+tend to put them immediately after each paragraph in which they're
+used, but if you want, you can put them all at the end of your
+document, sort of like footnotes.
+
+Here's an example of reference links in action:
+
+    I get 10 times more traffic from [Google] [1] than from
+    [Yahoo] [2] or [MSN] [3].
+
+      [1]: http://google.com/        "Google"
+      [2]: http://search.yahoo.com/  "Yahoo Search"
+      [3]: http://search.msn.com/    "MSN Search"
+
+Using the implicit link name shortcut, you could instead write:
+
+    I get 10 times more traffic from [Google][] than from
+    [Yahoo][] or [MSN][].
+
+      [google]: http://google.com/        "Google"
+      [yahoo]:  http://search.yahoo.com/  "Yahoo Search"
+      [msn]:    http://search.msn.com/    "MSN Search"
+
+Both of the above examples will produce the following HTML output:
+
+    
I get 10 times more traffic from Google than from
+    Yahoo
+    or MSN.

+
+For comparison, here is the same paragraph written using
+Markdown's inline link style:
+
+    I get 10 times more traffic from [Google](http://google.com/ "Google")
+    than from [Yahoo](http://search.yahoo.com/ "Yahoo Search") or
+    [MSN](http://search.msn.com/ "MSN Search").
+
+The point of reference-style links is not that they're easier to
+write. The point is that with reference-style links, your document
+source is vastly more readable. Compare the above examples: using
+reference-style links, the paragraph itself is only 81 characters
+long; with inline-style links, it's 176 characters; and as raw HTML,
+it's 234 characters. In the raw HTML, there's more markup than there
+is text.
+
+With Markdown's reference-style links, a source document much more
+closely resembles the final output, as rendered in a browser. By
+allowing you to move the markup-related metadata out of the paragraph,
+you can add links without interrupting the narrative flow of your
+prose.
+
+
+
Emphasis

+
+Markdown treats asterisks (`*`) and underscores (`_`) as indicators of
+emphasis. Text wrapped with one `*` or `_` will be wrapped with an
+HTML `` tag; double `*`'s or `_`'s will be wrapped with an HTML
+`` tag. E.g., this input:
+
+    *single asterisks*
+
+    _single underscores_
+
+    **double asterisks**
+
+    __double underscores__
+
+will produce:
+
+    single asterisks
+
+    single underscores
+
+    double asterisks
+
+    double underscores
+
+You can use whichever style you prefer; the lone restriction is that
+the same character must be used to open and close an emphasis span.
+
+Emphasis can be used in the middle of a word:
+
+    un*fucking*believable
+
+But if you surround an `*` or `_` with spaces, it'll be treated as a
+literal asterisk or underscore.
+
+To produce a literal asterisk or underscore at a position where it
+would otherwise be used as an emphasis delimiter, you can backslash
+escape it:
+
+    \*this text is surrounded by literal asterisks\*
+
+
+
+
Code

+
+To indicate a span of code, wrap it with backtick quotes (`` ` ``).
+Unlike a pre-formatted code block, a code span indicates code within a
+normal paragraph. For example:
+
+    Use the `printf()` function.
+
+will produce:
+
+    
Use the printf() function.

+
+To include a literal backtick character within a code span, you can use
+multiple backticks as the opening and closing delimiters:
+
+    ``There is a literal backtick (`) here.``
+
+which will produce this:
+
+    
There is a literal backtick (`) here.

+
+The backtick delimiters surrounding a code span may include spaces --
+one after the opening, one before the closing. This allows you to place
+literal backtick characters at the beginning or end of a code span:
+
+	A single backtick in a code span: `` ` ``
+	
+	A backtick-delimited string in a code span: `` `foo` ``
+
+will produce:
+
+	
A single backtick in a code span: `

+	
+	
A backtick-delimited string in a code span: `foo`

+
+With a code span, ampersands and angle brackets are encoded as HTML
+entities automatically, which makes it easy to include example HTML
+tags. Markdown will turn this:
+
+    Please don't use any `` tags.
+
+into:
+
+    
Please don't use any <blink> tags.

+
+You can write this:
+
+    `—` is the decimal-encoded equivalent of `—`.
+
+to produce:
+
+    
&#8212; is the decimal-encoded
+    equivalent of &mdash;.

+
+
+
+
Images

+
+Admittedly, it's fairly difficult to devise a "natural" syntax for
+placing images into a plain text document format.
+
+Markdown uses an image syntax that is intended to resemble the syntax
+for links, allowing for two styles: *inline* and *reference*.
+
+Inline image syntax looks like this:
+
+    ![Alt text](/path/to/img.jpg)
+
+    ![Alt text](/path/to/img.jpg "Optional title")
+
+That is:
+
+*   An exclamation mark: `!`;
+*   followed by a set of square brackets, containing the `alt`
+    attribute text for the image;
+*   followed by a set of parentheses, containing the URL or path to
+    the image, and an optional `title` attribute enclosed in double
+    or single quotes.
+
+Reference-style image syntax looks like this:
+
+    ![Alt text][id]
+
+Where "id" is the name of a defined image reference. Image references
+are defined using syntax identical to link references:
+
+    [id]: url/to/image  "Optional title attribute"
+
+As of this writing, Markdown has no syntax for specifying the
+dimensions of an image; if this is important to you, you can simply
+use regular HTML `` tags.
+
+
+* * *
+
+
+
Miscellaneous

+
+
+
+Markdown supports a shortcut style for creating "automatic" links for URLs and email addresses: simply surround the URL or email address with angle brackets. What this means is that if you want to show the actual text of a URL or email address, and also have it be a clickable link, you can do this:
+
+    
+    
+Markdown will turn this into:
+
+    http://example.com/
+
+Automatic links for email addresses work similarly, except that
+Markdown will also perform a bit of randomized decimal and hex
+entity-encoding to help obscure your address from address-harvesting
+spambots. For example, Markdown will turn this:
+
+    
+
+into something like this:
+
+    address@exa
+    mple.com
+
+which will render in a browser as a clickable link to "address@example.com".
+
+(This sort of entity-encoding trick will indeed fool many, if not
+most, address-harvesting bots, but it definitely won't fool all of
+them. It's better than nothing, but an address published in this way
+will probably eventually start receiving spam.)
+
+
+
+
Backslash Escapes

+
+Markdown allows you to use backslash escapes to generate literal
+characters which would otherwise have special meaning in Markdown's
+formatting syntax. For example, if you wanted to surround a word with
+literal asterisks (instead of an HTML `` tag), you can backslashes
+before the asterisks, like this:
+
+    \*literal asterisks\*
+
+Markdown provides backslash escapes for the following characters:
+
+    \   backslash
+    `   backtick
+    *   asterisk
+    _   underscore
+    {}  curly braces
+    []  square brackets
+    ()  parentheses
+    #   hash mark
+	+	plus sign
+	-	minus sign (hyphen)
+    .   dot
+    !   exclamation mark
+

+.Sh DESCRIPTION
+The
+.Nm
+utility takes a
+.Xr markdown 7 Ns -formatted
+.Pa textfile
+.Pq or stdin if not specified,
+compiles it, and combines it with a
+.Em template
+.Po
+.Pa page.theme
+by default
+.Pc
+to produce a web page.   If a path to the 
+template is not specified,
+.Nm
+looks for 
+.Pa page.theme
+in the current directory, then each parent directory up to the
+.Pa "document root"
+.Po
+set with
+.Fl d
+or, if unset, the
+.Em "root directory"
+of the system.
+.Pc
+If 
+.Pa page.theme
+is found,
+.Nm
+copies it to the output, looking for 
+.Em ""
+html tags and processing the embedded
+.Ar action 
+as appropriate.
+.Pp
+.Nm
+processes the following actions:
+.Bl -tag -width "include("
+.It Ar author
+Prints the author name(s) from the
+.Xr mkd_doc_author 3
+function.
+.It Ar body
+Prints the formatted
+.Xr markdown 7
+input file.
+.It Ar date
+Prints the date returned by
+.Xr mkd_doc_date 3
+or, if none, the
+date the input file was last modified.
+.It Ar dir
+Prints the directory part of the pagename
+.It Ar include Ns Pq Pa file 
+Prints the contents of 
+.Pa file .
+.Xr Markdown 7
+translation will
+.Em NOT
+be done on this file.
+.It Ar source
+The filename part of the pagename.
+.It Ar style
+Print any stylesheets
+.Pq see Xr mkd-extensions 7
+found in the input file.
+.It Ar title
+Print the title returned by
+.Xr mkd_doc_title 3 ,
+or, if that does not exist, the source filename.
+.It Ar version
+Print the version of
+.Xr discount 7
+that this copy of theme was compiled with.
+.El
+.Pp
+If input is coming from a file and the output was not set with the
+.Ar o
+option, 
+.Nm writes the output to
+.Pa file-sans-text.html
+.Pq if 
+.Ar file
+has a 
+.Pa .text
+suffix, that will be stripped off and replaced with 
+.Pa .html ;
+otherwise a
+.Pa .html
+will be appended to the end of the filename.)
+.Pp
+The options are as follows:
+.Bl -tag -width "-o file"
+.It Fl d Pa root
+Set the 
+.Em "document root"
+to
+.Ar root
+.It Fl f
+Forcibly overwrite existing html files.
+.It Fl o Pa filename
+Write the output to
+.Ar filename .
+.It Fl p Ar path
+Set the pagename to
+.Ar path .
+.It Fl t Ar filename
+Use
+.Ar filename
+as the template file.
