Big Tech Day 9

On June 3rd, Edwin presented an introduction to Idris at Big Tech Day 9.

The talk’s abstract:

Idris is a general purpose functional programming language with full dependent types, building on state-of-the-art techniques in programming language research. Dependent types allow types to be predicated on any value – in this way, required properties of a program can be captured in the type system, and verified by a type checker. This includes functional properties (i.e. does the program give the correct answer) and extra-functional properties (i.e. does the program run within specified resource constraints). Idris aims to bring type-based program verification techniques to programming practitioners while supporting efficient systems programming via an optimising compiler and interaction with external libraries. In this talk, I’ll use a series of examples to show how dependent types can be used for verifying realistic and important properties of software, from simple properties such as array bounds verification, to more complex properties of communicating and distributed systems.
