Please read the Dhall.Tutorial module, which contains a tutorial explaining how to use the language, the compiler, and this library

Input

input

Arguments

:: Decoder a

The decoder for the Dhall value

-> Text

The Dhall program

-> IO a

The decoded value in Haskell

Type-check and evaluate a Dhall program, decoding the result into Haskell

The first argument determines the type of value that you decode:

>>> input integer "+2"
2
>>> input (vector double) "[1.0, 2.0]"
[1.0,2.0]

Use auto to automatically select which type to decode based on the inferred return type:

>>> input auto "True" :: IO Bool
True

This uses the settings from defaultInputSettings.

inputWithSettings

Arguments

:: InputSettings

-> Decoder a

The decoder for the Dhall value

-> Text

The Dhall program

-> IO a

The decoded value in Haskell

Extend input with a root directory to resolve imports relative to, a file to mention in errors as the source, a custom typing context, and a custom normalization process.

Since: 1.16

inputFile

Arguments

:: Decoder a

The decoder for the Dhall value

-> FilePath

The path to the Dhall program.

-> IO a

The decoded value in Haskell.

Type-check and evaluate a Dhall program that is read from the file-system.

-> Decoder a

The decoder for the Dhall value

-> FilePath

The path to the Dhall program.

Similar to input, but without interpreting the Dhall Expr into a Haskell type.

Uses the settings from defaultInputSettings.

inputExprWithSettings

Arguments

:: InputSettings

-> Text

> input auto "True" :: IO Integer
 *** Exception: Error: Expression doesn't match annotation

 True : Integer

 (input):1:1

> detailed (input auto "True") :: IO Integer
 *** Exception: Error: Expression doesn't match annotation

 Explanation: You can annotate an expression with its type or kind using the
 ❰:❱ symbol, like this:


     ┌───────┐
     │ x : t │  ❰x❱ is an expression and ❰t❱ is the annotated type or kind of ❰x❱
     └───────┘

 The type checker verifies that the expression's type or kind matches the
 provided annotation

 For example, all of the following are valid annotations that the type checker
 accepts:


     ┌─────────────┐
     │ 1 : Natural │  ❰1❱ is an expression that has type ❰Natural❱, so the type
     └─────────────┘  checker accepts the annotation


     ┌───────────────────────┐
     │ Natural/even 2 : Bool │  ❰Natural/even 2❱ has type ❰Bool❱, so the type
     └───────────────────────┘  checker accepts the annotation


     ┌────────────────────┐
     │ List : Type → Type │  ❰List❱ is an expression that has kind ❰Type → Type❱,
     └────────────────────┘  so the type checker accepts the annotation


     ┌──────────────────┐
     │ List Text : Type │  ❰List Text❱ is an expression that has kind ❰Type❱, so
     └──────────────────┘  the type checker accepts the annotation


 However, the following annotations are not valid and the type checker will
 reject them:


     ┌──────────┐
     │ 1 : Text │  The type checker rejects this because ❰1❱ does not have type
     └──────────┘  ❰Text❱


     ┌─────────────┐
     │ List : Type │  ❰List❱ does not have kind ❰Type❱
     └─────────────┘


 You or the interpreter annotated this expression:

 ↳ True

 ... with this type or kind:

 ↳ Integer

 ... but the inferred type or kind of the expression is actually:

 ↳ Bool

 Some common reasons why you might get this error:

 ● The Haskell Dhall interpreter implicitly inserts a top-level annotation
   matching the expected type

   For example, if you run the following Haskell code:


     ┌───────────────────────────────┐
     │ >>> input auto "1" :: IO Text │
     └───────────────────────────────┘


   ... then the interpreter will actually type check the following annotated
   expression:


     ┌──────────┐
     │ 1 : Text │
     └──────────┘


   ... and then type-checking will fail

 ────────────────────────────────────────────────────────────────────────────────

Decoders

data Decoder a

A (Decoder a) represents a way to marshal a value of type 'a' from Dhall into Haskell

You can produce Decoders either explicitly:

example :: Decoder (Vector Text)
example = vector text

... or implicitly using auto:

example :: Decoder (Vector Text)
example = auto

You can consume Decoders using the input function:

input :: Decoder a -> Text -> IO a

Constructors

Decoder

Fields

• extract :: Expr Src Void -> Extractor Src Void a

  Extracts Haskell value from the Dhall expression

• expected :: Expr Src Void

  Dhall type of the Haskell value

Instances

Functor Decoder

Defined in Dhall

Methods

fmap :: (a -> b) -> Decoder a -> Decoder b

(<$) :: a -> Decoder b -> Decoder a

newtype RecordDecoder a

The RecordDecoder applicative functor allows you to build a Decoder from a Dhall record.

For example, let's take the following Haskell data type:

>>> :{
data Project = Project
  { projectName :: Text
  , projectDescription :: Text
  , projectStars :: Natural
  }
:}

And assume that we have the following Dhall record that we would like to parse as a Project:

{ name =
    "dhall-haskell"
, description =
    "A configuration language guaranteed to terminate"
, stars =
    289
}

Our decoder has type Decoder Project, but we can't build that out of any smaller decoders, as Decoders cannot be combined (they are only Functors). However, we can use a RecordDecoder to build a Decoder for Project:

>>> :{
project :: Decoder Project
project =
  record
    ( Project <$> field "name" strictText
              <*> field "description" strictText
              <*> field "stars" natural
    )
:}

liftA2 :: (a -> b -> c) -> RecordDecoder a -> RecordDecoder b -> RecordDecoder c

(*>) :: RecordDecoder a -> RecordDecoder b -> RecordDecoder b

(<*) :: RecordDecoder a -> RecordDecoder b -> RecordDecoder a

newtype UnionDecoder a

The UnionDecoder monoid allows you to build a Decoder from a Dhall union

For example, let's take the following Haskell data type:

>>> :{
data Status = Queued Natural
            | Result Text
            | Errored Text
:}

And assume that we have the following Dhall union that we would like to parse as a Status:

< Result : Text
| Queued : Natural
| Errored : Text
>.Result "Finish successfully"

Our decoder has type Decoder Status, but we can't build that out of any smaller decoders, as Decoders cannot be combined (they are only Functors). However, we can use a UnionDecoder to build a Decoder for Status:

>>> :{
status :: Decoder Status
status = union
  (  ( Queued  <$> constructor "Queued"  natural )
  <> ( Result  <$> constructor "Result"  strictText )
  <> ( Errored <$> constructor "Errored" strictText )
  )
:}

data SingletonConstructors

This type specifies how to model a Haskell constructor with 1 field in Dhall

For example, consider the following Haskell datatype definition:

class ToDhall a where

This class is used by FromDhall instance for functions:

instance (ToDhall a, FromDhall b) => FromDhall (a -> b)

You can convert Dhall functions with "simple" inputs (i.e. instances of this class) into Haskell functions. This works by:

• Marshaling the input to the Haskell function into a Dhall expression (i.e. x :: Expr Src Void)
• Applying the Dhall function (i.e. f :: Expr Src Void) to the Dhall input (i.e. App f x)
• Normalizing the syntax tree (i.e. normalize (App f x))
• Marshaling the resulting Dhall expression back into a Haskell value

conquer :: RecordEncoder a

encodeFieldWith :: Text -> Encoder a -> RecordEncoder a

Specify how to encode one field of a record by supplying an explicit Encoder for that field

encodeField :: ToDhall a => Text -> RecordEncoder a

Specify how to encode one field of a record using the default ToDhall instance for that type

recordEncoder :: RecordEncoder a -> Encoder a

Convert a RecordEncoder into the equivalent Encoder

newtype UnionEncoder a

UnionEncoder allows you to build an Encoder for a Dhall record.

For example, let's take the following Haskell data type:

>>> :{
data Status = Queued Natural
            | Result Text
            | Errored Text
:}

And assume that we have the following Dhall union that we would like to parse as a Status:

< Result : Text
| Queued : Natural
| Errored : Text
>.Result "Finish successfully"

Our encoder has type Encoder Status, but we can't build that out of any smaller encoders, as Encoders cannot be combined. However, we can use an UnionEncoder to build an Encoder for Status:

>>> :{
injectStatus :: Encoder Status
injectStatus = adapt >$< unionEncoder
  (   encodeConstructorWith "Queued"  inject
  >|< encodeConstructorWith "Result"  inject
  >|< encodeConstructorWith "Errored" inject
  )
  where
    adapt (Queued  n) = Left n
    adapt (Result  t) = Right (Left t)
    adapt (Errored e) = Right (Right e)
:}

Or, since we are simply using the ToDhall instance to inject each branch, we could write

>>> :{
injectStatus :: Encoder Status
injectStatus = adapt >$< unionEncoder
  (   encodeConstructor "Queued"
  >|< encodeConstructor "Result"
  >|< encodeConstructor "Errored"
  )
  where
    adapt (Queued  n) = Left n
    adapt (Result  t) = Right (Left t)
    adapt (Errored e) = Right (Right e)
:}

Constructors

UnionEncoder (Product (Const (Map Text (Expr Src Void))) (Op (Text, Expr Src Void)) a)

Contravariant UnionEncoder

Defined in Dhall

Methods

contramap :: (a -> b) -> UnionEncoder b -> UnionEncoder a

(>$) :: b -> UnionEncoder b -> UnionEncoder a

encodeConstructorWith :: Text -> Encoder a -> UnionEncoder a

Specify how to encode an alternative by providing an explicit Encoder for that alternative

encodeConstructor :: ToDhall a => Text -> UnionEncoder a

Specify how to encode an alternative by using the default ToDhall instance for that type

unionEncoder :: UnionEncoder a -> Encoder a

Convert a UnionEncoder into the equivalent Encoder

(>|<) :: UnionEncoder a -> UnionEncoder b -> UnionEncoder (Either a b) infixr 5

Combines two UnionEncoder values. See UnionEncoder for usage notes.

Ideally, this matches chosen; however, this allows UnionEncoder to not need a Divisible instance itself (since no instance is possible).

Miscellaneous

rawInput

Arguments

:: Alternative f

=> Decoder a

The decoder for the Dhall value

-> Expr s Void

a closed form Dhall program, which evaluates to the expected type

-> f a

The decoded value in Haskell

Use this function to extract Haskell values directly from Dhall AST. The intended use case is to allow easy extraction of Dhall values for making the function normalizeWith easier to use.

For other use cases, use input from Dhall module. It will give you a much better user experience.

(>$<) :: Contravariant f => (a -> b) -> f b -> f a infixl 4

This is an infix alias for contramap.

(>*<) :: Divisible f => f a -> f b -> f (a, b) infixr 5

The RecordEncoder divisible (contravariant) functor allows you to build an Encoder for a Dhall record.

For example, let's take the following Haskell data type:

>>> :{
data Project = Project
  { projectName :: Text
  , projectDescription :: Text
  , projectStars :: Natural
  }
:}

And assume that we have the following Dhall record that we would like to parse as a Project:

{ name =
    "dhall-haskell"
, description =
    "A configuration language guaranteed to terminate"
, stars =
    289
}

Our encoder has type Encoder Project, but we can't build that out of any smaller encoders, as Encoders cannot be combined (they are only Contravariants). However, we can use an RecordEncoder to build an Encoder for Project:

>>> :{
injectProject :: Encoder Project
injectProject =
  recordEncoder
    ( adapt >$< encodeFieldWith "name" inject
            >*< encodeFieldWith "description" inject
            >*< encodeFieldWith "stars" inject
    )
  where
    adapt (Project{..}) = (projectName, (projectDescription, projectStars))
:}

Or, since we are simply using the ToDhall instance to inject each field, we could write

>>> :{
injectProject :: Encoder Project
injectProject =
  recordEncoder
    ( adapt >$< encodeField "name"
            >*< encodeField "description"
            >*< encodeField "stars"
    )
  where
    adapt (Project{..}) = (projectName, (projectDescription, projectStars))
:}
