  1. ifor :: (TraversableWithIndex i t, Applicative f) => t a -> (i -> a -> f b) -> f (t b)

    diagrams-lib Diagrams.Prelude

    Traverse with an index (and the arguments flipped).

    for a ≡ ifor a . const
    iforflip itraverse
    

  2. iforM :: (TraversableWithIndex i t, Monad m) => t a -> (i -> a -> m b) -> m (t b)

    diagrams-lib Diagrams.Prelude

    Map each element of a structure to a monadic action, evaluate these actions from left to right, and collect the results, with access its position (and the arguments flipped).

    forM a ≡ iforM a . const
    iforMflip imapM
    

  3. iforMOf :: (Indexed i a (WrappedMonad m b) -> s -> WrappedMonad m t) -> s -> (i -> a -> m b) -> m t

    diagrams-lib Diagrams.Prelude

    Map each element of a structure targeted by a Lens to a monadic action, evaluate these actions from left to right, and collect the results, with access its position (and the arguments flipped).

    forMOf l a ≡ iforMOf l a . const
    iforMOfflip . imapMOf
    
    iforMOf :: Monad m => IndexedLens i s t a b      -> s -> (i -> a -> m b) -> m t
    iforMOf :: Monad m => IndexedTraversal i s t a b -> s -> (i -> a -> m b) -> m t
    

  4. iforMOf_ :: Monad m => IndexedGetting i (Sequenced r m) s a -> s -> (i -> a -> m r) -> m ()

    diagrams-lib Diagrams.Prelude

    Run monadic actions for each target of an IndexedFold or IndexedTraversal with access to the index, discarding the results (with the arguments flipped).

    iforMOf_flip . imapMOf_
    
    When you don't need access to the index then forMOf_ is more flexible in what it accepts.
    forMOf_ l a ≡ iforMOf l a . const
    
    iforMOf_ :: Monad m => IndexedGetter i s a     -> s -> (i -> a -> m r) -> m ()

    iforMOf_ :: Monad m => IndexedLens' i s a      -> s -> (i -> a -> m r) -> m ()
    iforMOf_ :: Monad m => IndexedTraversal' i s a -> s -> (i -> a -> m r) -> m ()
    

  5. iforM_ :: (FoldableWithIndex i t, Monad m) => t a -> (i -> a -> m b) -> m ()

    diagrams-lib Diagrams.Prelude

    Run monadic actions for each target of an IndexedFold or IndexedTraversal with access to the index, discarding the results (with the arguments flipped).

    iforM_flip imapM_
    
    When you don't need access to the index then forM_ is more flexible in what it accepts.
    forM_ a ≡ iforM a . const
    

  6. iforOf :: (Indexed i a (f b) -> s -> f t) -> s -> (i -> a -> f b) -> f t

    iforOfflip . itraverseOf
    
    iforOf :: Functor f     => IndexedLens i s t a b       -> s -> (i -> a -> f b) -> f t
    iforOf :: Applicative f => IndexedTraversal i s t a b  -> s -> (i -> a -> f b) -> f t
    iforOf :: Apply f       => IndexedTraversal1 i s t a b -> s -> (i -> a -> f b) -> f t
    

  7. iforOf_ :: Functor f => IndexedGetting i (Traversed r f) s a -> s -> (i -> a -> f r) -> f ()

    diagrams-lib Diagrams.Prelude

    Traverse the targets of an IndexedFold or IndexedTraversal with access to the index, discarding the results (with the arguments flipped).

    iforOf_flip . itraverseOf_
    
    When you don't need access to the index then forOf_ is more flexible in what it accepts.
    forOf_ l a ≡ iforOf_ l a . const
    
    iforOf_ :: Functor f     => IndexedGetter i s a     -> s -> (i -> a -> f r) -> f ()

  8. ifor_ :: (FoldableWithIndex i t, Applicative f) => t a -> (i -> a -> f b) -> f ()

    diagrams-lib Diagrams.Prelude

    Traverse elements with access to the index i, discarding the results (with the arguments flipped).

    ifor_flip itraverse_
    
    When you don't need access to the index then for_ is more flexible in what it accepts.
    for_ a ≡ ifor_ a . const
    

  9. lensRulesFor :: [(String, String)] -> LensRules

    diagrams-lib Diagrams.Prelude

    Construct a LensRules value for generating top-level definitions using the given map from field names to definition names.

  10. makeClassyFor :: String -> String -> [(String, String)] -> Name -> DecsQ

    diagrams-lib Diagrams.Prelude

    Derive lenses and traversals, using a named wrapper class, and specifying explicit pairings of (fieldName, traversalName). Example usage:

    makeClassyFor "HasFoo" "foo" [("_foo", "fooLens"), ("bar", "lbar")] ''Foo
