Welcome to the website for IFL 2018, the 30th Symposium on Implementation and Application of Functional Languages. The goal of the IFL symposia is to bring together researchers actively engaged in the implementation and application of functional and function-based programming languages. IFL 2018 will be a venue for researchers to present and discuss new ideas and concepts, work in progress, and publication-ripe results related to the implementation and application of functional languages and function-based programming.

Haskell Mini-Course (September 5th)

This year, on the day before the paper presentations start, we will begin with a mini-course on Haskell presented by David Thrane Christiansen and José Manuel Calderón Trilla of Galois, Inc.

Register: Attendance at the course is free, but you must RSVP using this form.

Course Description:

Recent versions of the GHC compiler for Haskell feature support for a number of advanced type system features, including pattern-matching functions in the type system (type families), indexed families (generalized algebraic datatypes, or GADTs), type-level data structures (data kinds), and general compile-time metaprogramming (Template Haskell). At Galois, we use these features in a number of our projects, which allows us to build deep embeddings of programming languages and have GHC enforce the target language's type system for us. This style of programming ensures that we only produce well-typed terms, including that we do not forget any of the run-time checks that are necessary to preserve our invariants when accepting input from untyped sources such as files.

In the course of developing these projects, some common problems and programming patterns emerged. We developed the `parameterized-utils` library to codify solutions to these problems, and provide necessary generalizations of interfaces from the standard library (Eq, Applicative, Traversable, etc.)

We will expect that participants in the course have used Haskell before, but we will not expect everyone to be experts. We will introduce GADTs, type families, and data kinds, and then show how to use them together with the tools from parameterized-utils with an implementation of the simply-typed lambda calculus, including basic AST definitions, evaluation, and parsing.
