AsciiDoc

Hello, World!
============
Author Name, <author@domain.foo>

you can write text http://example.com[with links], optionally
using an explicit link:http://example.com[link prefix].

* single quotes around a phrase place 'emphasis'
** alternatively, you can put underlines around a phrase to add _emphasis_
* astericks around a phrase make the text *bold*
* pluses around a phrase make it +monospaced+
* `smart' quotes using a leading backtick and trailing single quote
** use two of each for double ``smart'' quotes

- escape characters are supported
- you can escape a quote inside emphasized text like 'here\'s johnny!'

Inductive seq : nat -> Set :=

Fixpoint length (n : nat) (s : seq n) {struct s} : nat :=
  match s with

  | consn i _ s' => S (length i s')
  end.

Theorem length_corr : forall (n : nat) (s : seq n), length n s = n.
Proof.
  intros n s.

  (* reasoning by induction over s. Then, we have two new goals
     corresponding on the case analysis about s (either it is
     niln or some consn *)
  induction s.

    (* We are in the case where s is void. We can reduce the
       term: length 0 niln *)
    simpl.

    (* We obtain the goal 0 = 0. *)
    trivial.

    (* now, we treat the case s = consn n e s with induction
       hypothesis IHs *)
    simpl.

    (* The induction hypothesis has type length n s = n.
       So we can use it to perform some rewriting in the goal: *)
    rewrite IHs.

    (* Now the goal is the trivial equality: S n = S n *)
    trivial.

  (* Now all sub cases are closed, we perform the ultimate
     step: typing the term built using tactics and save it as
     a witness of the theorem. *)

Feature: Addition
  In order to avoid silly mistakes
  As a math idiot
  I want to be told the sum of two numbers

  @this_is_a_tag
  Scenario Outline: Add two numbers
    * I have a calculator
    Given I have entered <input_1> into the calculator
    And I have entered <input_2> into the calculator
    When I press <button>
    Then the result should be <output> on the screen
    And I have a string like
    """
    Here is
    some
    multiline text
    """

  Examples:
    | input_1 | input_2 | button | output |
    | 20      | 30      | add    | 50     |
    | 2       | 5       | add    | 7      |
    | 0       | 40      | add    | 40     |

Syntax highlighting is an action applying to one thing.
Understand "highlight [something preferably codeish]" as syntax highlighting.

Code is a kind of thing. Code is usually plural-named.

Code can be highlighted. Code is usually not highlighted.

Check syntax highlighting:
  unless the noun is code:
    say "[The noun] isn't source code you can highlight.";
    rule fails.

Carry out syntax highlighting:
  now the noun is highlighted.
