      To do this thing, first you'll need to do this other thing. We do this because of
      reasons. Here's what that looks like in code.

Section Heading

Slide Title

  • This is a fake lecture
  • But it should show lots of feature of our Sphinx system
  • It is also a test case for our builders/CSS stylesheets
  • As you add features/CSS classes/etc, please add them here

Another Slide Title

  • It's Pretty Rare
  • But You Can Have a Subsection!

Subsection

Like This

Basic Styling

Typography

Put blank lines between paragraphs.

Basic Styling

  • For emphasis, use italics
  • For more emphasis, use bold
  • For link, use Go to Google

Citations

Citations use single backticks: `like this`. Use for:

  • variable names
    • eg: We can now set x
  • file or path names
    • eg: Store this in secrets.sh
  • class names
    • eg: Remember our Cat class?
  • function or method names
    • eg: Never call lets_play_global_thermonuclear_war

Do not use this for general emphasis, please! Use bold or italics for that.

Code Literals

Code literals use double backticks: ``like this``

These are for literal code blocks or literal coding values:

  • things like x = 0
  • but not for just talking about a variable, function, etc.
    • use citations for that
  • eg: call set_color like this: set_color('blue')

Dashes

Use 3 dashes for an em dash---like this.

Two dashes makes an "en dash"--it's too short!

Superscripts and Subscripts

O(n2)

log2n

.. only:: not revealjs

  Notice how we use a backslashed space there---it's not legal
  to have styles right next to a word (like O(n`2`:sup:), which
  doesn't look right). The backslash space separates the tokens,
  but does't add a real space.

Line Breaks

As an example:

You can force line breaks
by doing this

Or, you can add a slide-only break |reveal-br| like this.

Symbols

.. newslide::
  • |pycmd| The command to run Python

And the same replacement, inside the console:

$ |pycmd| `show_prompt.py`:cmd:

Lists

Lists

  • Always put blank line between bulleted list items
  • Otherwise bad things will happen!
    • You can have many levels
    • Just indent them
      • Useful for further explanations
    • Try to stick to 2
      • Our CSS only stylizes up to level 3
      • So stop here
  • And back to level one

Complex Lists

  • You can also have lists that are not "simple"

    This is where you have multiple paragraphs in a list

    • You can still nest these

      Like so

.. newslide::

More about complex lists:

  • This happens with things like code blocks

    x = 0

  • See?

.. newslide::

More about complex lists:

  • Another case is

  • Where you have a simple list

    • Containing a complex list

      This has a second paragraph

  • The spacing should work out

Horizontal Lists

You can make short, side-by-side lists like this:

.. hlist::

  - one

  - two

  - three

  - four

You can specify # columns, too:

.. hlist::
  :columns: 3

  - one

  - two

  - three

  - four

  - five

  - six

Organization

Organization

If your slide title is the same as the section title, like this, the handouts won't repeat it. So do this for things like the "Goals" slide in a "Goals" section.

New Slides

When you want slide break that shouldn't cause a new heading in the handouts, |reveal-br| use the newslide directive.

.. newslide::

This is a new slide with the same title, but on the handouts, it just flows.

Note: slide content isn't contained in newslide, it just appears after it.

.. newslide:: New Title

This is a new slide with a new title, but on the handouts, it just flows.

.. newslide:: +(continued)

A new slide with an addition to the title.

.. newslide:: Colors
  :background: yellow

You can also use newslide to get background colors

.. newslide:: Images
  :background: porcupine.jpg

`Or images!`:white:

.. interslide::

  Interslides never appear on the handouts and don't have a title.

  They're useful for fun, silly things, like large images and text.

  Notice the content of interslide is inside the interslide.


.. interslide::

  You can put any type of content in an interslide.

  .. image:: porcupine.jpg
    :width: 100%


.. interslide::
  :background: porcupine.jpg

  `They can also have backgrounds`:white:

Images

Images

Add images like so:

porcupine.jpg

It's good to set a width on it --- otherwise, these are huge on the handouts.

.. newslide::

To make an image smaller on handouts, size it with ems:

porcupine.jpg

(since ems are so much bigger on slides than handouts)

.. only:: not revealjs

  This is especially good for things like book cover images,
  since we want them to appear big on slides for visual pop,
  but they can appear much smaller on handouts.


.. newslide::

For images without good definition, you can add a border:

porcupine.jpg

.. newslide::

For less-important images that should appear in handouts but not on printed material, use the noprint class:

porcupine.jpg

Transitions

Arbitrary Items

To make things appear one at a time, use the incremental directive

.. incremental:: one

  .. code-block:: rst

    .. incremental:: one

      Like this


.. incremental:: one

  Using it multiple times works, too!

Lists

You can use on lists, too!

.. incremental:: item

  - This causes each top-level bullet point

  - To appear at once

    - But secondary points

    - Appear with parents

  - Like so


.. newslide::

The nest-incremental class makes each bullet appear incrementally:

.. incremental:: nest

  - Each bullet

    - Now appears

      - Incrementally

  - Like so


.. newslide::

Works on numbered lists:

.. incremental:: item

  #. One

  #. Two

  #. Three


.. newslide::

And definition lists:

.. incremental:: item

  Term one
    This is a definition list

  Term two
    Use it to define or describe terms


.. newslide::

When you use .. incremental:: nest on a definition list, both terms and definitions will appear one at a time:

.. incremental:: nest

  Term one
    Definition

  Et cetera
    Definition

Effects

We rarely use these, but they work so here ya go

.. incremental:: one
  :class: grow

  This Grows!


.. incremental:: one
  :class: fade-out

  This fades out


.. incremental:: one
  :class: current-visible

  This is visible then goes away

Literal Blocks

Literal Blocks

To show literal text blocks, use the explicit code-block directive

Hello! *not italics*

Parsed Literal

You can use parsed literal for literal blocks that still parse for style stuff.

Hello italics and citation and `red`:red:

Console

We use a special class on parsed literal for showing shell commands:

$ `echo "this is a command"`:cmd:
this is a command

$ `echo`:cmd:  `# comment`:comment:

Hello

Code Blocks

Code Blocks

Ask for a code block like so

if name == "joel":
    print("hi")
<a href="yo.html">&copy; <!-- comment --></a>

(also: js, sql, xml, and many others---see "pygments" library)

Emphasizing Lines

Can emphasize lines:

if name == "joel":
    print("hi")
    print("there")
    print("joel")
    print("and")
    print("everyone")
    print("else")

Add Captions

if name == "joel":
    print("hi")
.. only:: not revealjs

  It's our style to use this for the filenames of demo files
  or if some explanation is needed of where this code is coming from.


if name == "joel":
    print("hi")

Literal Includes

Whenever possible, don't inline code --- it's too easy for it to have bugs!

Instead, keep the code in a separate file, so we can test it and include as demo code

.. newslide::


.. literalinclude:: demo-demo/demo-include.py


.. newslide::

Can use caption/name like for code blocks:

.. literalinclude:: demo-demo/demo-include.py
  :caption: A Demo


.. newslide::

Better, if caption is there but blank, it gets file name

.. literalinclude:: demo-demo/demo-include.py
  :caption:

Finding Things

Can only include certain lines and can emphasize:

.. literalinclude:: demo-demo/demo-include.py
  :lines: 1, 2, 14-15
  :emphasize-lines: 3


.. newslide::

Better is to find things with pyobject

.. literalinclude:: demo-demo/demo-include.py
  :pyobject: Cat


.. newslide::

Can also use start-after and end-before to match text:

.. literalinclude:: demo-demo/demo-include.py
  :start-after: Do other stuff


.. literalinclude:: demo-demo/demo-include.py
  :lines: 3-
  :end-before: Do other stuff


.. newslide::

This lets us show only one method on a class:

.. literalinclude:: demo-demo/demo-include.py
  :pyobject: Cat.meow
  :prepend: class Cat:  # ...

This is used when we want to highlight part of a longer class.

.. newslide::

Or, if we want to pull the method out to show it simply:

.. literalinclude:: demo-demo/demo-include.py
  :pyobject: Cat.meow
  :dedent: 4

(The dedent removes four leading spaces)

Don't Use code

There's also a code directive that works for Sphinx but it appears to be undocumented. We style it the same, but don't use it---use code-block, instead.

Notes, Sidebars, Hints, etc.

Admonition

Notes, warnings, and hints are all subclasses of the admonition directive.

They all require titles!

You can put anything inside of 'em and they only appear in handouts.

Notes

Notes are blue.

Note

This is a note.

It goes on.

And on.

Use notes for sidebar-style information.

Note

Other Stuff In Notes

You can put anything ou want in a note.

if name == "joel":
    print("hi")

Warnings

Use warnings to catch students' attention and warn them about gotchas.

Warning

This is a warning.

Make sure you run this command in the correct directory.

Hints

Hints are special; their content is hidden behind an expanding toggle.

Hint

Using a certain data structure will make this problem easier

You could solve this in other ways, but using a linked list (or a doubly-linked list) is often a good way to solve this problem. You can do so by making the list "circular" --- having the last item in the linked list point back to the first item.

This will let you traverse the list, removing items until one remains.

Hiding Details

If you want to hide something that's not a hint, use toggle-reveal

.. togglereveal::

  Write a function that takes in a number and blah blah blah.

Containers

Containers

The container directive just adds a div.

Boring!

This is useful if you want to put a class on it:

Now I have someclass on my div

Big Code

big makes code blocks and literal blocks bigger

if name == "joel":
    print("hi")
.. newslide:: Works with Parsed Literals


Hey, I'm `red`:red: and big!

Hey, I'm also `red`:red: and big!

Small Code

For longer listings:

.. literalinclude:: demo-demo/demo-include.py
  :caption: (normal size)

.. literalinclude:: demo-demo/demo-include.py
  :caption: (smaller)

Text-Heavy

For big, bold text on slides, use text-heavy:

Like this

Or even `like this`:text-heavy:

Comparing Things

Comparing Things

Instead of just one thing:

if (name == "joel")
    console.log("hi");

Side-by-side comparisons are useful:

if (name == "joel")
    console.log("hi");
if name == "joel":
    print("hi")
.. newslide::
The spacing should look right even if we lead with compare, or if the compares are textual.
if name == "joel":
    print("hi")
if name == "joel2":
    print("hi")
.. newslide::

You can compare an arbitrary # of things:

Hi
  • A list
  • Of things
print('Hello, world!')

Only

Only

To have things only appear on slides:

.. only:: revealjs

  This only appears on slides

To have things not appear on slides, but everywhere else:

.. only:: not revealjs

  This does not appear on slides.

  Don't ever say "only:: handouts"---since we have other possible
  non-slide formats (LaTeX, epub, etc). Always say "only:: not revealjs".

Definition Lists

Definition Lists

A Definition List
Is useful for things like
Glossary Terms
And stuff like that
.. newslide::
Also Works

When the things are multi-paragraph

like here.

Should Look Ok
Even if some thing are not multi-paragraph

Tables

Standard Table

Data Structure Get Add Delete Iterate Memory

  ====================== =========== =========== =========== ============ ============

Quotes

Quote

Always use the explicit epigraph directive

A rose is a rose is a rose.

—Gertrude Stein

.. newslide::

I like green eggs and ham.

I really do. I'm Sam I Am.

—Sam I Am

Do not add quotes --- our CSS will do that for you

Plots

Math

Math

Adding math:

r = \frac{\sum^n_{i=1}(x_i - \bar{x})(y_i - \bar{y})}{\sqrt{\Sigma^n_{i=1}(x_i - \bar{x})^2 \times \Sigma^n_{i=1}(y_i - \bar{y})^2}}

Or n = {x}^2 for inline.

Graphs

Graphs

Graphviz graphs are super-common and useful:

.. digraph:: org
  :revealjs: width: 50%;
  :handouts: width: 80%;

  Organisms -> { Plants, Fungi, Animals, Bacteria, Protists };
  Animals -> { Cnidaria, Molluscs, Chordata, Arthropods, Echinoderms };
  Chordata -> { Actinopterygii, Mammalia, Chondrichthyes, Aves, Amphibia, Reptilia };
  Mammalia -> { Carnivora, Primate, Artiodactyla, Rodentia };

Put in sizes for revealjs, handouts, and latex.

Generally, handouts and latex will be about half the size of revealjs.

Colors

Colors

You can use colors:

.. newslide::

How these look in a literal block:

`red`:red: `green`:green: `orange`:orange: `tan`:tan: `blue`:blue: `purple`:purple: `yellow`:yellow: `gray`:gray: `gone`:gone: `inv-red`:inv-red:

And in a console:

`cmd`:cmd: `red`:red: `green`:green: `orange`:orange: `tan`:tan: `blue`:blue: `purple`:purple: `yellow`:yellow: `gray`:gray: `gone`:gone: `inv-red`:inv-red:

Speaker Notes

Speaker Notes

You can add speaker notes with the speaker directive. These appear in "speaker notes" view (press S in revealjs). This never appears on handouts.

.. speaker::

  Example speaker note.
