NL-FP dag 2018
The Dutch Functional Programming Day is an annual gathering of researchers, students, and practitioners sharing a common interest in functional programming. The day features talks that cover the latest advances in research, teaching, and applications in the functional programming area. Coffee and lunch breaks provide ample opportunity for networking with your colleagues and meeting new people. Experts and newcomers to the field are equally welcome.
The NL-FP day 2018 takes place on Friday, January 5, 2018 at the Walter Bos Complex of the Dutch Tax and Customs Administration in Apeldoorn.
The FP-day takes place in De Kern at the Walter Bos Complex of the Dutch Tax and Customs Administration in Apeldoorn.

Registration and deadline
Please note that to the nature of the location, registration in advance is required. As well as matching identification (passport, driver's license, or similar) before entering the venue! Photography and/or setting up a local WiFi network is explicitly not allowed. There will be a photographer present during the day.
Please register by sending an email to email@example.com including
- your name, as shown on passport or driver's license
- your affiliation, if any
- whether you want (vegetarian) pizza
- whether you want to give a talk
There are no costs for anything this year, as it is fully sponsored by the Dutch Tax and Customs Administration.
The registration deadline is December 15th, as we need a list of participants for the security staff. Please register early, since we also need this to order the right number of badges, drinks and pizza's.
- 9:30 Registration
- 10:15 Welcome and a few words from our sponsor
- 10:30 - 12:30 Presentations with a coffee break
- 12:30 Lunch
- 14:00 - 16:30 Presentations with a coffee break
- 16:45 Drinks
- 17:30 Pizza's
More details will follow.
A dinner (pizza's) and drinks will be provided free of charge at the end of the day at the same location. Given that registration is mandatory this time, we'll assume that you stay around for this unless you specify otherwise.

The following people already requested to present a talk:
Camil Staps - Cloogle: a programming language search engine and its applications
Cloogle (https://cloogle.org) is a search engine for the Clean language, similar to Haskell's Hoogle. The modular setup makes it fairly easy to be reused in other programs, like Integrated Development Environments (IDEs) and editor plugins. In this talk we give a general overview of the system and show how it evolved from a web interface to grep into its current state. We also discuss the things we are currently working on: client-side search and editor integration.
Victor Miraldo - Type-Directed Diffing of Structured Data
The Unix diff utility that compares lines of text is used pervasively by version control systems. Yet certain changes to a program may be di cult to describe accurately in terms of modi cations to indi- vidual lines of code. As a result, observing changes at such a xed granularity may lead to unnecessary con icts between di erent ed- its. This talk discusses a generic representation for describing trans- formations between algebraic data types. These representa- tions can be used to give a more accurate account of modi cations made to algebraic data structures – and the abstract syntax trees of computer programs in particular – as opposed to only considering modi cations between their textual representations.
Jan Kuper - FPGA design using CλaSH
It is widely recognized that mainstream hardware design languages (VHDL, Verilog) have poor abstraction mechanisms, turning FPGA design into a cumbersome activity. Most high level synthesis languages only partially solve this problem, mostly because they take a sequential perspective. CλaSH, on the other hand, starts from a mathematical perspective exploiting the abstraction mechanisms of the functional programming language Haskell, including polymorphism, type derivation, and higher order functions. Since every CλaSH specification is an executable Haskell program, testing and debugging can be done at top level. Further advantages of a mathematical approach to hardware design are the possibility to transformations on a given design to get an optimal space-time performance. We will illustrate the approach with several examples.
Bas van Dijk
Gert Veldhuijzen van Zanten
At the Dutch Tax Authority we apply a model driven approach to software engineering. The approach aims to make models that directly describe the actual legislation that is being executed and to provide early feedback using model checks and model execution. We develop domein specific languages including editors, static type checkers, interpreters and code generators. In the talk we will present our vision on agile law execution using domain specific languages and demo our specification environment.
Mart Lubbers - Task Oriented Pearl: Distributed Blockchain Applications
Blockchain calculations are very suitable to implement in a functional programming language. For example, mining a new block is a oneliner in Clean. However, distribution, validation and interfacing is less trivial to implement. Task Oriented Programming (TOP) is a novel programming paradigm implemented as an EDSL in Clean that supports collaboration of parties in a distributed setting. The basic building blocks are tasks and shared data sources and multiuser web applications are generated from the specification. We show that it is natural to implement distributed blockchain applications in a TOP language such as iTasks.
