I'm a H2 title with 2 columns

I'm a H3 title

I'm a H4 title.

And this is a paragraph.

Code 

# hello.exs
defmodule Greeter do
  def greet(name) do
    message = "Hello, " <> name <> "!"
    IO.puts message
  end
end

Greeter.greet("world")

Paragraphs

Paragraphs are also supported and can quote code.

Several paragraphs are visually distinct.

Lists

  • Element 1
  • Element 2
  • piece of code

Table

Date (H4 header)

ExampleOutput
%m/%d/%Y06/05/2013
%A, %B %e, %YSunday, June 5, 2013
%b %e %aJun 5 Sun

Variants

Adding variants 

## H2
{: .col-2}

### H3

Variants customize how your cheatsheet looks like via Markdown's inline attribute notation.

Header variants

.col-2two-columns
.col-3three-columns
.col-2-lefttwo-columns (1/3 - 2/3)

H3

.list-6six-columns for lists

Code

Code with headings

index.ex

Path.join(["~", "foo"])
"~/foo"

other.ex

Path.join(["foo"])
"foo"

Code blocks can have headings.

Long lines 

defmodule MyTracer do
  def trace({:remote_function, _meta, module, name, arity}, env) do
    IO.puts "#{env.file}:#{env.line} #{inspect(module)}.#{name}/#{arity}"
    :ok
  end

  def trace(_event, _env) do
    :ok
  end
end

Long lines show scrollbars.

Line wrapping 

defmodule MyTracer do
  def trace({:remote_function, _meta, module, name, arity}, env) do
    IO.puts "#{env.file}:#{env.line} #{inspect(module)}.#{name}/#{arity}"
    :ok
  end

  def trace(_event, _env) do
    :ok
  end
end

Add wrap to wrap long lines.
