Idris
Overview
Idris is a general purpose pure functional programming language with dependent types. Dependent types allow types to be predicated on values, meaning that some aspects of a program’s behaviour can be specified precisely in the type. It is compiled, with eager evaluation. Its features are influenced by Haskell and ML, and include:
- Full dependent types with dependent pattern matching
- Simple foreign function interface (to C)
- Compiler-supported interactive editing: the compiler helps you write code using the types
- where clauses, with rule, simple case expressions, pattern matching let and lambda bindings
- Dependent records with projection and update
- Interfaces (similar to type classes in Haskell)
- Type-driven overloading resolution
- do notation and idiom brackets
- Indentation significant syntax
- Extensible syntax
- Cumulative universes
- Totality checking
- Hugs style interactive environment
