This crud is called HTML (HyperText Markup Language) and it is basically a very simple programming language instructing your web browser how to draw a page on a screen. Anyone can learn HTML and many people do. The important thing is that no matter what splendid multimedia web pages they might represent, HTML files are just telegrams.

When Ronald Reagan was a radio announcer, he used to call baseball games by reading the terse descriptions that trickled in over the telegraph wire and were printed out on a paper tape. He would sit there, all by himself in a padded room with a microphone, and the paper tape would eke out of the machine and crawl over the palm of his hand printed with cryptic abbreviations. If the count went to three and two, Reagan would describe the scene as he saw it in his mind’s eye: “The brawny left-hander steps out of the batter’s box to wipe the sweat from his brow. The umpire steps forward to sweep the dirt from home plate.” and so on. When the cryptogram on the paper tape announced a base hit, he would whack the edge of the table with a pencil, creating a little sound effect, and describe the arc of the ball as if he could actually see it. His listeners, many of whom presumably thought that Reagan was actually at the ballpark watching the game, would reconstruct the scene in their minds according to his descriptions.

This is exactly how the World Wide Web works: the HTML files are the pithy description on the paper tape, and your Web browser is Ronald Reagan. The same is true of Graphical User Interfaces in general.

An h1 header

Paragraphs are separated by a blank line.

2nd paragraph. Italic, bold, and monospace. Itemized lists +look like:

this one
that one
the other one

Note that — not considering the asterisk — the actual text +content starts at 4-columns in.

+
Block quotes are +written like so.
+
They can span multiple paragraphs, +if you like.

Use 3 dashes for an em-dash. Use 2 dashes for ranges (ex., “it’s all +in chapters 12–14”). Three dots … will be converted to an ellipsis. +Unicode is supported. ☺

An h2 header

Here’s a numbered list:

first item
second item
third item

Note again how the actual text starts at 4 columns in (4 characters +from the left side). Here’s a code sample:

# Let me re-iterate ...
+for i in 1 .. 10 { do-something(i) }
+

As you probably guessed, indented 4 spaces. By the way, instead of +indenting the block, you can use delimited blocks, if you like:

define foobar() {
+    print "Welcome to flavor country!";
+}
+

(which makes copying & pasting easier). You can optionally mark the +delimited block for Pandoc to syntax highlight it:

import time
+# Quick, count to ten!
+for i in range(10):
+    # (but not *too* quick)
+    time.sleep(0.5)
+    print i
+

An h3 header

Now a nested list:

+
First, get these ingredients:
+
- carrots
- celery
- lentils
+
+
Boil some water.
+

Dump everything in the pot and follow +this algorithm:

find wooden spoon
+uncover pot
+stir
+cover pot
+balance wooden spoon precariously on pot handle
+wait 10 minutes
+goto first step (or shut off burner when done)
+

Do not bump wooden spoon or it will fall.

Notice again how text always lines up on 4-space indents (including +that last line which continues item 3 above).

Here’s a link to a website, to a local +doc, and to a section heading in the current +doc. Here’s a footnote ¹.

Tables can look like this:

+ + + + + + + + + + + + + + + + + + + + + + + + + +

size	material	color
9	leather	brown
10	hemp canvas	natural
11	glass	transparent

Table: Shoes, their sizes, and what they’re made of

(The above is the caption for the table.)

A horizontal rule follows.

Here’s a definition list:

apples: Good for making applesauce.
oranges: Citrus!
tomatoes: There’s no “e” in tomatoe.

(Put a blank line between each term/definition pair to spread +things out more.)

and images can be specified like so:

example image

Inline math equations go in like so: $\omega = d\phi / dt$. +Display math should get its own line and be put in in +double-dollarsigns:

$$I = \int \rho R^{2} dV$$

And note that you can backslash-escape any punctuation characters +which you wish to be displayed literally, ex.: `foo`, *bar*, etc.
