Patat and Myanmar travels

Presentations And The ANSI Terminal

Presentations in the terminal

At work, I frequently need to give (internal) presentations and demos using video conferencing. I prefer to do these quick-and-dirty presentations in the terminal for a few reasons:

The last point is important for video conferencing especially. The software we use allows you to share a single window from your desktop. This is pretty neat if you have a multi-monitor setup. However, it does not play well with switching between a PDF viewer and a terminal.

Introducing patat

To this end, I wrote patatPresentations And The ANSI Terminal – because I was not entirely happy with the available solutions. You can get it from Hackage: cabal install patat.

You run it simply by doing:


The key features are:

An example of a presentation is:

title: This is my presentation
author: Jane Doe

# This is a slide

Slide contents.  Yay.

# Important title

Things I like:

- Markdown
- Haskell
- Pandoc
- Traveling

How patat came to be

I started writing a simple prototype of patat during downtime at ICFP2016, when I discovered that MDP was not able to parse my presentation correctly.

After ICFP, I flew to Myanmar, and I am currently traveling around the country with my girlfriend. It’s a super interesting place to visit, with a rich history. Now that NLD is the ruling party, I think it is a great time to visit the country responsibly.

However, it is a huge country – the largest in south-east Asia – so there is some downtime traveling on domestic flights, buses and boats. I thought it was a good idea to improve the tool a bit further, since you don’t need internet to hack on this sort of thing.

Pull requests are welcome as always! Note that I will be slow to respond: for the next three days I will be trekking from Kalaw to Inle Lake, so I have no connectivity (or electricity, for that matter).

Sidenote: “Patat” is the Flemish word for “potato”. Dutch people also use it to refer to French Fries but I don’t really do that – in Belgium we just call fries “Frieten”.
