module Prelude {- The Prelude is minimal (since it is effectively part of the language specification, this seems to be desirable - we should, nevertheless, aim to provide a good selection of base libraries). A rule of thumb is that it should contain the basic functions required by almost any non-trivial program. As such, it should contain: - Anything the elaborator can desugar to (e.g. pairs, unit, =, laziness) - Basic types Bool, Nat, List, Dec, Maybe, Either - The most important utility functions: id, the, composition, etc - Interfaces for arithmetic and implementations for the primitives and basic types - Char and String manipulation - Show, Eq, Ord, and implementations for all types in the prelude - Interfaces and functions for basic proof (cong, Uninhabited, etc) -- - Semigroup, Monoid - Functor, Applicative, Monad and related functions - Foldable, Traversable - Range for range syntax - Console IO and interfaces for supporting IO Everything else should be in the base libraries, and imported as required. In particular, proofs of Nat/List properties that almost never get used in practice would probably be better in base libraries. Everything should be total, unless there's a good justification for it not to be (division by zero, as a concrete example). (These guidelines will probably get revised a few times.) -} import public Builtin import public PrimIO import public Prelude.Basics as Prelude import public Prelude.Cast as Prelude import public Prelude.EqOrd as Prelude import public Prelude.Interfaces as Prelude import public Prelude.Interpolation as Prelude import public Prelude.IO as Prelude import public Prelude.Num as Prelude import public Prelude.Ops as Prelude import public Prelude.Show as Prelude import public Prelude.Types as Prelude import public Prelude.Uninhabited as Prelude
