NAME
patat - Presentations Atop The ANSI Terminal
SYNOPSIS
patat [*options*] file
DESCRIPTION
Controls
• Next slide: space, enter, l, →, PageDown
• Previous slide: backspace, h, ←, PageUp
• Go forward 10 slides: j, ↓
• Go backward 10 slides: k, ↑
• First slide: 0
• Last slide: G
• Reload file: r
• Quit: q
The r key is very useful since it allows you to preview your slides while you are writing
them. You can also use this to fix artifacts when the terminal is resized.
Input format
The input format can be anything that Pandoc supports. Plain markdown is usually the most
simple solution:
---
title: This is my presentation
author: Jane Doe
...
# This is a slide
Slide contents. Yay.
---
# Important title
Things I like:
- Markdown
- Haskell
- Pandoc
Horizontal rulers (---) are used to split slides.
However, if you prefer not use these since they are a bit intrusive in the markdown, you
can also start every slide with a header. In that case, the file should not contain a
single horizontal ruler.
patat will pick the most deeply nested header (e.g. h2) as the marker for a new slide.
Headers above the most deeply nested header (e.g. h1) will turn into title slides, which
are displayed as as a slide containing only the centered title.
This means the following document is equivalent to the one we saw before:
---
title: This is my presentation
author: Jane Doe
...
# This is a slide
Slide contents. Yay.
# Important title
Things I like:
- Markdown
- Haskell
- Pandoc
And that following document contains three slides: a title slide, followed by two content
slides.
---
title: This is my presentation
author: Jane Doe
...
# Chapter 1
## This is a slide
Slide contents. Yay.
## Another slide
Things I like:
- Markdown
- Haskell
- Pandoc

Configuration
patat is fairly configurable. The configuration is done using YAML. There are two places
where you can put your configuration:
1. In the presentation file itself, using the Pandoc metadata header.
2. In $HOME/.patat.yaml
For example, we set an option key to val by using the following file:
---
title: Presentation with options
author: John Doe
patat:
key: val
...
Hello world.
Or we can use a normal presentation and have the following $HOME/.patat.yaml:
key: val
Line wrapping
Line wrapping can be enabled by setting wrap: true in the configuration. This will
re-wrap all lines to fit the terminal width better.
Auto advancing
By setting autoAdvanceDelay to a number of seconds, patat will automatically advance to
the next slide.
---
title: Auto-advance, yes please
author: John Doe
patat:
autoAdvanceDelay: 2
...
Hello World!
---
This slide will be shown two seconds after the presentation starts.
Note that changes to autoAdvanceDelay are not picked up automatically if you are running
patat --watch. This requires restarting patat.
Advanced slide splitting
You can control the way slide splitting works by setting the slideLevel variable. This
variable defaults to the least header that occurs before a non-header, but it can also be
explicitly defined. For example, in the following document, the slideLevel defaults to 2:
# This is a slide
## This is a nested header
This is some content
With slideLevel 2, the h1 will turn into a "title slide", and the h2 will be displayed at
the top of the second slide. We can customize this by setting slideLevel manually:
---
patat:
slideLevel: 1
...
# This is a slide
## This is a nested header
This is some content
Now, we will only see one slide, which contains a nested header.
Fragmented slides
By default, slides are always displayed "all at once". If you want to display them
fragment by fragment, there are two ways to do that. The most common case is that lists
should be displayed incrementally.
This can be configured by settings incrementalLists to true in the metadata block:
---
title: Presentation with incremental lists
author: John Doe
patat:
incrementalLists: true
...
- This list
- is displayed
- item by item
Setting incrementalLists works on all lists in the presentation. To flip the setting for
a specific list, wrap it in a block quote. This will make the list incremental if
incrementalLists is not set, and it will display the list all at once if incrementalLists
is set to true.
This example contains a sublist which is also displayed incrementally, and then a sublist
which is displayed all at once (by merit of the block quote).
---
title: Presentation with incremental lists
author: John Doe
patat:
incrementalLists: true
...
- This list
- is displayed
* item
* by item
- Or sometimes
> * all at
> * once
Another way to break up slides is to use a pagraph only containing three dots separated by
spaces. For example, this slide has two pauses:
Legen
. . .
wait for it
. . .
Dary!
Theming
Colors and other properties can also be changed using this configuration. For example, we
can have:
---
author: 'Jasper Van der Jeugt'
title: 'This is a test'
patat:
wrap: true
theme:
emph: [vividBlue, onVividBlack, bold]
imageTarget: [onDullWhite, vividRed]
...
# This is a presentation
This is _emph_ text.
The properties that can be given a list of styles are:
blockQuote, borders, bulletList, codeBlock, code, definitionList, definitionTerm, emph,
header, imageTarget, imageText, linkTarget, linkText, math, orderedList, quoted,
strikeout, strong, tableHeader, tableSeparator
The accepted styles are:
bold, dullBlack, dullBlue, dullCyan, dullGreen, dullMagenta, dullRed, dullWhite,
dullYellow, onDullBlack, onDullBlue, onDullCyan, onDullGreen, onDullMagenta, onDullRed,
onDullWhite, onDullYellow, onVividBlack, onVividBlue, onVividCyan, onVividGreen,
onVividMagenta, onVividRed, onVividWhite, onVividYellow, underline, vividBlack, vividBlue,
vividCyan, vividGreen, vividMagenta, vividRed, vividWhite, vividYellow
Syntax Highlighting
As part of theming, syntax highlighting is also configurable. This can be configured like
this:
---
patat:
theme:
syntaxHighlighting:
decVal: [bold, onDullRed]
...
...
decVal refers to "decimal values". This is known as a "token type". For a full list of
token types, see this list -- the names are derived from there in an obvious way.
OPTIONS
-w, --watch
If you provide the --watch flag, patat will watch the presentation file for changes
and reload automatically. This is very useful when you are writing the
presentation.
-f, --force
Run the presentation even if the terminal claims it does not support ANSI features.
-d, --dump
Just dump all the slides to stdout. This is useful for debugging.
--version
Display version information.
