# Motivation

As the MOOSE framework continues to develop so does the documentation requirements. To minimize the amount duplicate documentation a presentation building program was developed to convert wiki content from MOOSE wiki into presentation slides.

The goal is to have one location for all MOOSE related content, the wiki, from which information can be extracted in a MOOSE-like way to generate slides suitable for presentations and tutorials.

# Getting Started

Before learning how to generate slides, it is important to understand the basic framework from which this tool was formulated around Remark, which is a "A simple, in-browser, Markdown-driven slideshow tool..."

Before continuing please review the Remark demo: remarkjs.com.

# Creating Suitable Wiki Content

Unfortunately, the markdown syntax utilized by Remark and mooseframework.org are slightly different. The following list details how to formulate mooseframework.org/wiki content in a form suitable for conversion to Remark syntax.

• Slides are separated by [](---)
• Animation steps within a slide are separated by [](--)
• Remark properties are entered as [](property: value). For example, to change the class settings for the current slide place [](class: center, middle) within the wiki content for the current slide.
• Comments, which are viewable in presentation mode (press p within the Remark presentation) are created by using [](??? Enter your comments here).
• In general, all Remark syntax may be entered inside the parentheses as [](Remark command here), the only limitation is that the brackets must be preceded by a space.

# Math Equations

In order to properly convert math equations from the www.mooseframework.org/wiki to Remark slides they must be implemented in a specific way, this is due to the different rendering engines used by the two platforms.

• In-line equations are encapsulated by double dollar signs: $$y=\int x dx$$\$.
• Equation blocks should be encapsulated in triple dollar signs and begin on a newline: \underbrace{\left(\nabla\psi, k\nabla u \right)}_{Kernel} - \underbrace{\langle\psi, k\nabla u\cdot \hat{n} \rangle}_{BoundaryCondition} + \underbrace{\left(\psi, \vec{\beta} \cdot \nabla u\right)}_{Kernel} - \underbrace{\left(\psi, f\right)}_{Kernel} = 0

# Images

No special wiki syntax is required for including images; however, there is special syntax within the input file to adjust the appearance of the image for inclusion in the presentation.

A demonstration image that is sized and aligned from within the presentation input file.

# Slide and Wiki Links

It is possible to create links to mooseframework.org wiki content using the headings. For example, [Math Equations](#math-equations) result in creating a link to the Math Equations page.

When the wiki content is converted to slides, the first heading in the slide, i.e., the heading that follows [](---) is converted into the slide name. Thus, internal wiki links such as the Math Equations link will continue to operate correctly.

# Input File Syntax

Slide shows may be generated from www.mooseframework.org/wiki content using an input file syntax similar to MOOSE itself, the following information details the input file that converts the wiki content for this tutorial into a presentation.

This complete input file for the presentation constructed from this wiki is included in ~/projects/moose/python/PresentationBuilder/examples/example_02.i.

## Adding a Slide Set

It is possible to add any number of slide sets, think of these as Kernels. In this class a single slide set is being added. In this example the CoverSet object is being utilized to create a cover page for the entire presentation.

[presentation]
[./cover]
type = CoverSet
title = '**PresentationBuilder**<br><br> A tool for generating slides from MOOSE wiki content'
background-image = 'inl_dark_title.png'
class = 'middle, cover'
contents = true
• type Determines what slide set object to build, in this case the CoverSet is used which to build a presentation cover page and table-of-contents.
• title The title to place on the title page. Note, the name of this slide is cover-title.
• background-image Sets the background of all slides in the slide set to use the specified image.
• contents Enables the automatically generated table of contents slide. Note, the name of this slide is cover-contents.

## Customizing Slides

It is possible to customize the appearance of individual slides from within the input file, this is done by include a [./Slides] sub-block within a slide set block.

    [./Slides]
[./cover-contents]
background-image = 'inl_white_slide.png'
class = 'left, top'
[../]
[../]
[../]

In this case, the Remark property for the slide named "cover-contents" is modified to change the alignment and background image.

## Wiki Content

To include wiki content the DjangoWikiSet is utilized in an additional top-level input file block, as follows.

  [./demo]
type = DjangoWikiSet
wiki = 'PresentationBuilder'
background-image = 'inl_white_slide.png'
contents = true
title = 'Slides extracted from the mooseframework.org wiki'

In this case this wiki page (www.mooseframework.org/wiki/PresentationBuilder) is being utilize for the source of the slide content. The title and contents parameters create a title and contents slide specific to the slide content for this set of slides.

Again, the slides for this set may be modified from the input file. In this case the cover slides background and CSS style are altered, as is the "input-file-syntax" slide with was adjusted to center the content vertically and horizontally.

    [./Slides]
[./demo-title]
class = 'middle, cover'
background-image = 'inl_dark_title.png'
[../]
[../]

Notice, by default if a new slide does not contain a heading, as in the case for this and the previous slide, the heading from the previous slide is utilized with "(cont.)" append.

## Customizing Images

Within the wiki the image may be sized for use in the presentation by including special syntax: [](image:203 width:200px). This changes the settings for image 203 and may be placed anywhere on the wiki.

In similar fashion to slide customization, images may also be customized using the [./Images] sub-block. These settings overwrite the setting implemented within the wiki.

  ...
[./Images]
[./64]
align = 'center'
width = '500px'
[../]
[../]
[../]

In this case, image number 64 is modified to be center aligned with a total width of 500 pixels. The image number is the id reference used by the mooseframework.org wiki to insert images.

## Creating Custom CSS

It is also possible to create custom CSS class, this is accomplished by adding blocks to the [./CSS] block in the input file.

  [./CSS]
[./remark-code]
font-size = '14px'
[../]
[./cover]
color = '#ffffff'
[../]
[../]
[]

The [./remark-code] block modifies the Remark code block format to utilize a smaller font. The [./cover] creates a new class with white text and padding at the left side. This class is used by the title page.

## Creating Columns

It is possible to create column within a slide by using custom CSS and relying on the Remark content class support.

To create columns:

• Add the column layout(s) to the CSS block of your input file
• In the markdown add the column breaks, using Remark syntax, but protecting the commands using the syntax described previously Creating Suitable Wiki Content. For, example this slide contains such commands to invoke the column creation.

[./right-column]
width = '30%'
float = 'right'
[../]
[./left-column]
width = '65%'
float = 'left'
[../]
