Futhark.MonadFreshNames

Description

This module provides a monadic facility similar (and built on top of) Futhark.FreshNames. The removes the need for a (small) amount of boilerplate, at the cost of using some GHC extensions. The idea is that if your compiler pass runs in a monad that is an instance of MonadFreshNames, you can automatically use the name generation functions exported by this module.

Synopsis

Documentation

class (Applicative m, Monad m) => MonadFreshNames m where Source #

A monad that stores a name source. The following is a good instance for a monad in which the only state is a NameSource vn:

 instance MonadFreshNames vn MyMonad where
   getNameSource = get
   putNameSource = put

modifyNameSource :: MonadFreshNames m => (VNameSource -> (a, VNameSource)) -> m a Source #

Run a computation needing a fresh name source and returning a new one, using getNameSource and putNameSource before and after the computation.

newName :: MonadFreshNames m => VName -> m VName Source #

Produce a fresh name, using the given name as a template.

newNameFromString :: MonadFreshNames m => String -> m VName Source #

As newName, but takes a String for the name template.

newVName :: MonadFreshNames m => String -> m VName Source #

Produce a fresh VName, using the given base name as a template.

newIdent :: MonadFreshNames m => String -> Type -> m Ident Source #

Produce a fresh Ident, using the given name as a template.

newIdent' :: MonadFreshNames m => (String -> String) -> Ident -> m Ident Source #

Produce a fresh Ident, using the given Ident as a template, but possibly modifying the name.

newParam :: MonadFreshNames m => String -> dec -> m (Param dec) Source #

Produce a fresh Param, using the given name as a template.

data VNameSource Source #

A name source is conceptually an infinite sequence of names with no repeating entries. In practice, when asked for a name, the name source will return the name along with a new name source, which should then be used in place of the original.

The Ord instance is based on how many names have been extracted from the name source.
