  1. idft :: Transform (Complex Double) (Complex Double)

    vector-fftw Numeric.FFT.Vector.Unnormalized

    A backward discrete Fourier transform. The output and input sizes are the same (n). 

    y_k = sum_(j=0)^(n-1) x_j e^(2pi i j k/n)

  2. idft :: TransformND (Complex Double) (Complex Double)

    vector-fftw Numeric.FFT.Vector.Unnormalized.Multi

    A backward discrete Fourier transform. The output and input sizes are the same (n).

  3. idToken :: OAuth2Token -> Maybe IdToken

    yesod-auth-oauth2 Network.OAuth.OAuth2.Compat

    Exists when openid scope is in the Authorization Request and the provider supports OpenID protocol.

  4. idToken :: OAuth2Token -> Maybe IdToken

    yesod-auth-oauth2 Yesod.Auth.OAuth2

    Exists when openid scope is in the Authorization Request and the provider supports OpenID protocol.

  5. idToken :: OAuth2Token -> Maybe IdToken

    yesod-auth-oauth2 Yesod.Auth.OAuth2.Prelude

    Exists when openid scope is in the Authorization Request and the provider supports OpenID protocol.

  6. idownward :: forall i j h s a . Ord i => AnIndexedLens' i s a -> (h :> (s :@ j)) -> (h :> (s :@ j)) :> (a :@ i)

    zippers Control.Zipper

    Step down into a IndexedLens. This is a constrained form of ifromWithin for when you know there is precisely one target that can never fail. 

    idownward :: IndexedLens' i s a -> (h :> s:@j) -> h :> s:@j :> a:@i

  7. idownward :: forall i j h s a . Ord i => AnIndexedLens' i s a -> (h :> (s :@ j)) -> (h :> (s :@ j)) :> (a :@ i)

    zippers Control.Zipper.Internal

    Step down into a IndexedLens. This is a constrained form of ifromWithin for when you know there is precisely one target that can never fail. 

    idownward :: IndexedLens' i s a -> (h :> s:@j) -> h :> s:@j :> a:@i

  8. identifyForm :: forall (m :: Type -> Type) a . Monad m => Text -> (Markup -> MForm m (FormResult a, WidgetFor (HandlerSite m) ())) -> Markup -> MForm m (FormResult a, WidgetFor (HandlerSite m) ())

    classy-prelude-yesod ClassyPrelude.Yesod

    Creates a hidden field on the form that identifies it. This identification is then used to distinguish between missing and wrong form data when a single handler contains more than one form. For instance, if you have the following code on your handler: 

    ((fooRes, fooWidget), fooEnctype) <- runFormPost fooForm
((barRes, barWidget), barEnctype) <- runFormPost barForm
    Then replace it with 
    ((fooRes, fooWidget), fooEnctype) <- runFormPost $ identifyForm "foo" fooForm
((barRes, barWidget), barEnctype) <- runFormPost $ identifyForm "bar" barForm
    Note that it's your responsibility to ensure that the identification strings are unique (using the same one twice on a single handler will not generate any errors). This allows you to create a variable number of forms and still have them work even if their number or order change between the HTML generation and the form submission.

  9. ident :: Parser e ByteString

    dotparse DotParse.FlatParse

    Parse an identifier.

  10. ident :: Parser e ByteString

    dotparse DotParse.FlatParse.TH

    Parse an identifier.
