The symposium on Trends in Functional Programming (TFP) is an international forum for researchers with interests in all aspects of functional programming, taking a broad view of current and future trends in the area. It aspires to be a lively environment for presenting the latest research results, and other contributions (see below). Authors of draft papers will be invited to submit revised papers based on the feedback receive at the symposium.  A post-symposium refereeing process will then select a subset of these
articles for formal publication.

TFP 2015 will be the main event of a pair of functional programming events. TFP 2015 will be accompanied by the International Workshop on Trends in Functional Programming in Education (TFPIE), which will take place on June 2nd.

The TFP symposium is the heir of the successful series of Scottish Functional Programming Workshops. Previous TFP symposia were held in:

  • Edinburgh (Scotland) in 2003;
  • Munich (Germany) in 2004;
  • Tallinn (Estonia) in 2005;
  • Nottingham (UK) in 2006;
  • New York (USA) in 2007;
  • Nijmegen (The Netherlands) in 2008;
  • Komarno (Slovakia) in 2009;
  • Oklahoma (USA) in 2010;
  • Madrid (Spain) in 2011;
  • St. Andrews (UK) in 2012;
  • Provo (Utah, USA) in 2013;
  • and in Soesterberg (The Netherlands) in 2014.

TFP is pleased to announce talks by the following two invited speakers:

* Laurence Rideau is a researcher at INRIA and is interested in the semantics of programming languages , the formal methods, and the verification tools for programs and mathematical proofs.  She participated in the beginnings of the Compcert project (certified compiler), and is part of the Component Mathematical team in the MSR-INRIA joint laboratory, who performed the formalization of the Feit-Thompson theorem successfully.

Thirty years ago, computers barged in mathematics with the famous proof of the Four Color Theorem.  Initially limited to simple calculation, their role is now expanding to the reasoning whose complexity is beyond the capabilities of most humans, as the proof of the classification of finite simple groups.  We present our large collaborative adventure around the formalization of the Feit-Thompson theorem ( that is a first step to the classification of finite groups and that uses a palette of methods and techniques that range from formal logic to software (and mathematics) engineering.

* Anil Madhavapeddy is a University Lecturer at the University of Cambridge. He has worked in a variety of senior architecture, engineering, product management, sales and “whatever it takes” roles in industry (S, M, L, XL) as well as government and research (S, M, L).

Much cloud infrastructure consists of small, specialised services that interoperate via protocol interconnects such as HTTP or DNS. Managing these service deployments currently requires large operating system and application stacks with ad-hoc configuration management. In this talk, I explore an alternative approach that builds tiny specialised protocol VMs known as “unikernels”, and coordinates them by means of the “Irmin” mergeable datastructure library. These datastructures can be manipulated much like Git (with pull, push and merge operators), and form higher level control structures for persistent work queues, key-value stores, with well-defined consistency properties. Our initial prototypes can be compiled to small Xen unikernels that boot in milliseconds, and debugged and introspected using the standard “git” command line tools.

This is leading our MirageOS project towards an interesting future where we can program against a persistent and durable fabric of functional distributed datastructures that drive complex use-cases such as SSL/TLS stacks or POSIX filesystems that are resilient and secure thanks to the use of functional programming techniques.
