Main goals

  1. Easy generation of slides
  2. Integration with R and Julia
  3. Looks nice

Fonts and spacing

The document uses the \alert{Noto} family -- https://www.google.com/get/noto/

Main body : Noto Sans (or Serif)

Maths : $\text{Noto Sans}$

Code : Noto Mono

The linespread value has been increased to about $1.3$

Serif font theme

The default font theme is sans serif. You can change the template/pl.tex first line to:

@@ -1,4 +1,4 @@
-\documentclass[11pt, compress, aspectratio=1610]{beamer}
+\documentclass[11pt, compress, aspectratio=1610, serif]{beamer}

\usetheme{pl}

Colors

The structure elements are in teal, inline code is in blue, and alerted text in \alert{orange}.

The background is off-white: it will look like it's white, but with less eyestrain.

The foreground is not-quite-black either.

Using images

\includegraphics[width=\textwidth]{figures/density.pdf}

Maths

The Input family of fonts has some support for Greek and mathematical symbols:

$$ \frac{1}{N}\frac{\text{d}}{\text{d}t}N = N\left(r-\alert{\alpha N}\right) $$

You can use \alert within math blocks.

Using sections

Section titles

Every section will have a small band with the background image.

They are first-level headers in markdown:

# Section

## Slide-title

Slide content

Code highlighting

There is a customized color scheme for code highlighting.

α = 2.0
b, c = "abc", 'c'
# This code does nothing (useful)
for i in 1:10
  rand()
  @elapsed println("i:\t$i")
end

We can also use \alert{unicode characters}.

Visual counter

The circle next to the title of each slide moves forward at every slide (including the section changes).

It is a useful visual key for how much slides are left.

Output

Pellentesque habitant morbi tristique senectus et netus et malesuada fames ac turpis egestas. Morbi sollicitudin nisi vitae lorem interdum, eget elementum quam elementum. Curabitur quis leo eu metus consequat ultricies. Curabitur sit amet convallis risus. Cras vel arcu id risus efficitur commodo et eget velit. Curabitur consequat eleifend magna, ut ultricies lorem scelerisque eu. Mauris faucibus neque sit amet est elementum, suscipit placerat est interdum. Phasellus sed convallis est. Nunc fermentum convallis odio eget gravida. Duis venenatis dictum tempor.

Background image

The background image is generated from the makebackground.jl file. It's the k-nearest neighbour graph of a series of random points.

The file is background.png -- it can be replaced by any file \alert{as long as} the replacement file is in the 16:10 format (for example, a 1600 $\times$ 1000 image).

Final slide

The final slide displays the background picture.

This is to avoid the awkward "Switching to black" thing that happens when there are no slides left.

Reproducible documents

It's in the Makefile

Documents slides.Jmd and slides.Rmd will be detected.

They will be converted to slides.md using either R/knitr or Julia/Weave.jl.

Specific commands

Cropped images

\begincols \column{0.68\textwidth}

The roundpicture command will display a picture, resized to fit into a circle:

\roundpicture{images/nb.png}{Optional text}

Note that the image \alert{must} be a square.

\hfill\column{0.28\textwidth}

\roundpicture{images/nb.png}{}

\stopcols

Citation

To quickly add specific references in the corner of the slide:

\smallcitation{Gravel et al. 2006 \textit{Ecol. Lett}}

\smallcitation{Gravel et al. 2006 \textit{Ecol. Lett}}

Plain slide

This will create a plain slide:

## {.plain}

\plain{This is large text on the background image.}

Note that the text within the \plain command \alert{must be \LaTeX}.

{.plain}

\plain{This is large text on the background image.}
