Presentex

A HTML based presentation framework for Elixir.

Why use Presentex?

• It has very simple understandable HTML, CSS and JavaScript
• It works offline
• It has only three dependencies
  • jQuery
  • highlight.js
  • flowtype.js
• It has a very simple way to provide Elixir code samples
• It uses a larger default font size than most presentation frameworks
• All slides are generated from Elixir data structures

License Information

• presentex: LICENSE
• highlight.js: https://github.com/isagalaev/highlight.js/blob/master/LICENSE
• jQuery: https://github.com/jquery/jquery/blob/master/LICENSE.txt
• flowtype.js: https://github.com/simplefocus/FlowType.JS/blob/master/LICENSE.txt

Usage

Add the dependency to your mix.exs file:

  defp deps do
    [{:presentex, "~> 0.0.10"}]
  end

Make sure that you do not use version 0.0.1, it will not work.

  Do *NOT* use version 0.0.1, it is known to be buggy.

You can create Presentex presentations using the standard Elixir tool mix.

• Create a mix project if you don't have one already
• Create a file with the content of your slides
• Run mix gen.presentation <output-dir> <slide-content-file>

Then simply open the /index.html file in your browser. No internet connection is required.

Slides

The slides all belong in one file. They are separated by commas.

View a sample slide file at test/sample_slides.ex

The generated output of test/sample_slides.ex is also checked in under the sample directory.

The slide types are:

Title with subtitle

  [title: "Elixir for noobs", subtitle: "A better way to program"]

Heading

  [heading: "New Features"]

Paragraph of text

  "Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod
  tempor incididunt ut labore et dolore magna aliqua."

Bullet list of items

  ["Improved error handling", "Fixed memory leak in mysql driver",
    "Added UTF-8 support in library"]

A quote

  [blockquote: "To code, or not to code. That is a dumb question.",
    author: "Bryan Weber"]

Elixir code

There are three different ways to include Elixir code.

  Source.code(

      defmodule Ticket do
        def process(tkt, new_status) do
          tkt
          |> Workflow.Engine.status
          |> Workflow.Engine.transition new_status
        end
      end

  )

  [elixir: """

  defmodule Foo do
    def bar do
      IO.puts "quux"
    end
  end

  """]

  [code: """

  defmodule Foo do
    def bar do
      IO.puts "quux"
    end
  end

  """]

Source Code (for languages other than Elixir)

The list of supported languages can be found at highlight.js

  [code: """

  PrepareAlarm = fun(Room) ->
      io:format("Alarm set in ~s.~n",[Room]),
      fun() -> io:format(
                 "Alarm tripped in ~s! Call Batman!~n",
                 [Room])
      end
  end.
