Dhall.Core
Description
This module contains the core calculus for the Dhall language.
Dhall is essentially a fork of the morte compiler but with more built-in
functionality, better error messages, and Haskell integration

Syntax
Constants for a pure type system
The axioms are:
⊦ Type : Kind ⊦ Kind : Sort
... and the valid rule pairs are:
⊦ Type ↝ Type : Type -- Functions from terms to terms (ordinary functions) ⊦ Kind ↝ Type : Type -- Functions from types to terms (type-polymorphic functions) ⊦ Sort ↝ Type : Type -- Functions from kinds to terms ⊦ Kind ↝ Kind : Kind -- Functions from types to types (type-level functions) ⊦ Sort ↝ Kind : Sort -- Functions from kinds to types (kind-polymorphic functions) ⊦ Sort ↝ Sort : Sort -- Functions from kinds to kinds (kind-level functions)
Note that Dhall does not support functions from terms to types and therefore Dhall is not a dependently typed language
Instances
Internal representation of a directory that stores the path components in reverse order
In other words, the directory /foo/bar/baz is encoded as
Directory { components = [ "baz", "bar", "foo" ] }

Label for a bound variable
The Text field is the variable's name (i.e. "x").
The Int field disambiguates variables with the same name if there are
multiple bound variables of the same name in scope. Zero refers to the
nearest bound variable and the index increases by one for each bound
variable of the same name going outward. The following diagram may help:
┌──refers to──┐
│ │
v │
λ(x : Type) → λ(y : Type) → λ(x : Type) → x@0
┌─────────────────refers to─────────────────┐
│ │
v │
λ(x : Type) → λ(y : Type) → λ(x : Type) → x@1This Int behaves like a De Bruijn index in the special case where all
variables have the same name.
You can optionally omit the index if it is 0:
┌─refers to─┐
│ │
v │
λ(x : Type) → λ(y : Type) → λ(x : Type) → xZero indices are omitted when pretty-printing Vars and non-zero indices
appear as a numeric suffix.

data RecordField s a Source #
Record the field of a record-type and record-literal expression. The reason why we use the same ADT for both of them is because they store the same information.
For example,
{ {- A -} x {- B -} : {- C -} T }... or
{ {- A -} x {- B -} = {- C -} T }will be instantiated as follows:
recordFieldSrc0corresponds to theAcomment.recordFieldValueisTrecordFieldSrc1corresponds to theBcomment.recordFieldSrc2corresponds to theCcomment.
Although the A comment isn't annotating the T Record Field,
this is the best place to keep these comments.
Note that recordFieldSrc2 is always Nothing when the RecordField is for
a punned entry, because there is no = sign. For example,
{ {- A -} x {- B -} }will be instantiated as follows:
recordFieldSrc0corresponds to theAcomment.recordFieldValuecorresponds to(Var "x")recordFieldSrc1corresponds to theBcomment.recordFieldSrc2will beNothing
The labels involved in a record using dot-syntax like in this example:
{ {- A -} a {- B -} . {- C -} b {- D -} . {- E -} c {- F -} = {- G -} e }will be instantiated as follows:
- For both the
aandbfield,recordfieldSrc2isNothing - For the
afield: recordFieldSrc0corresponds to theAcommentrecordFieldSrc1corresponds to theBcomment- For the
bfield: recordFieldSrc0corresponds to theCcommentrecordFieldSrc1corresponds to theDcomment- For the
cfield: recordFieldSrc0corresponds to theEcommentrecordFieldSrc1corresponds to theFcommentrecordFieldSrc2corresponds to theGcomment
That is, for every label except the last one the semantics of
recordFieldSrc0 and recordFieldSrc1 are the same from a regular record
label but recordFieldSrc2 is always Nothing. For the last keyword, all
srcs are Just

Normalization
alphaNormalize :: Expr s a -> Expr s a Source #

normalize :: Eq a => Expr s a -> Expr t a Source #
Reduce an expression to its normal form, performing beta reduction
normalize does not type-check the expression. You may want to type-check
expressions before normalizing them since normalization can convert an
ill-typed expression into a well-typed expression.
normalize can also fail with error if you normalize an ill-typed
expression
normalizeWith :: Eq a => Maybe (ReifiedNormalizer a) -> Expr s a -> Expr t a Source #
Reduce an expression to its normal form, performing beta reduction and applying any custom definitions.
normalizeWith is designed to be used with function typeWith. The typeWith
function allows typing of Dhall functions in a custom typing context whereas
normalizeWith allows evaluating Dhall expressions in a custom context.
To be more precise normalizeWith applies the given normalizer when it finds an
application term that it cannot reduce by other means.
Note that the context used in normalization will determine the properties of normalization. That is, if the functions in custom context are not total then the Dhall language, evaluated with those functions is not total either.
normalizeWith can fail with an error if you normalize an ill-typed
expression
normalizeWithM :: (Monad m, Eq a) => NormalizerM m a -> Expr s a -> m (Expr t a) Source #
This function generalizes normalizeWith by allowing the custom normalizer
to use an arbitrary Monad
normalizeWithM can fail with an error if you normalize an ill-typed
expression
type Normalizer a = NormalizerM Identity a Source #
An variation on NormalizerM for pure normalizers
type NormalizerM (m :: Type -> Type) a = forall s. Expr s a -> m (Maybe (Expr s a)) Source #
Use this to wrap you embedded functions (see normalizeWith) to make them
polymorphic enough to be used.
newtype ReifiedNormalizer a Source #
A reified Normalizer, which can be stored in structures without
running into impredicative polymorphism.

judgmentallyEqual :: Eq a => Expr s a -> Expr t a -> Bool Source #
Returns True if two expressions are α-equivalent and β-equivalent and
False otherwise
judgmentallyEqual can fail with an error if you compare ill-typed
expressions
subst :: Var -> Expr s a -> Expr s a -> Expr s a Source #
Substitute all occurrences of a variable with an expression
subst x C B ~ B[x := C]
shift :: Int -> Var -> Expr s a -> Expr s a Source #
shift is used by both normalization and type-checking to avoid variable
capture by shifting variable indices
For example, suppose that you were to normalize the following expression:
λ(a : Type) → λ(x : a) → (λ(y : a) → λ(x : a) → y) x
If you were to substitute y with x without shifting any variable
indices, then you would get the following incorrect result:
λ(a : Type) → λ(x : a) → λ(x : a) → x -- Incorrect normalized form
In order to substitute x in place of y we need to shift x by 1 in
order to avoid being misinterpreted as the x bound by the innermost
lambda. If we perform that shift then we get the correct result:
λ(a : Type) → λ(x : a) → λ(x : a) → x@1
As a more worked example, suppose that you were to normalize the following expression:
λ(a : Type) → λ(f : a → a → a) → λ(x : a) → λ(x : a) → (λ(x : a) → f x x@1) x@1
The correct normalized result would be:
λ(a : Type) → λ(f : a → a → a) → λ(x : a) → λ(x : a) → f x@1 x
The above example illustrates how we need to both increase and decrease variable indices as part of substitution:
- We need to increase the index of the outer
x@1tox@2before we substitute it into the body of the innermost lambda expression in order to avoid variable capture. This substitution changes the body of the lambda expression to(f x@2 x@1) - We then remove the innermost lambda and therefore decrease the indices of
both
xs in(f x@2 x@1)to(f x@1 x)in order to reflect that one lessxvariable is now bound within that scope
Formally, (shift d (V x n) e) modifies the expression e by adding d to
the indices of all variables named x whose indices are greater than
(n + m), where m is the number of bound variables of the same name
within that scope
In practice, d is always 1 or -1 because we either:
- increment variables by
1to avoid variable capture during substitution - decrement variables by
1when deleting lambdas after substitution
n starts off at 0 when substitution begins and increments every time we
descend into a lambda or let expression that binds a variable of the same
name in order to avoid shifting the bound variables by mistake.
isNormalized :: Eq a => Expr s a -> Bool Source #
Quickly check if an expression is in normal form
Given a well-typed expression e, isNormalized ee == .normalize e
Given an ill-typed expression, isNormalized may fail with an error, or
evaluate to either False or True!
isNormalizedWith :: (Eq s, Eq a) => Normalizer a -> Expr s a -> Bool Source #
Check if an expression is in a normal form given a context of evaluation.
Unlike isNormalized, this will fully normalize and traverse through the expression.
It is much more efficient to use isNormalized.
isNormalizedWith can fail with an error if you check an ill-typed
expression
shallowDenote :: Expr s a -> Expr s a Source #
freeIn :: Eq a => Var -> Expr s a -> Bool Source #
Detect if the given variable is free within the given expression

subExpressions :: Applicative f => (Expr s a -> f (Expr s a)) -> Expr s a -> f (Expr s a) Source #
A traversal over the immediate sub-expressions of an expression.
subExpressionsWith :: Applicative f => (a -> f (Expr s b)) -> (Expr s a -> f (Expr s b)) -> Expr s a -> f (Expr s b) Source #
A traversal over the immediate sub-expressions of an expression which allows mapping embedded values
chunkExprs :: Applicative f => (Expr s a -> f (Expr t b)) -> Chunks s a -> f (Chunks t b) Source #
A traversal over the immediate sub-expressions in Chunks.
bindingExprs :: Applicative f => (Expr s a -> f (Expr s b)) -> Binding s a -> f (Binding s b) Source #
recordFieldExprs :: Applicative f => (Expr s a -> f (Expr s b)) -> RecordField s a -> f (RecordField s b) Source #
Traverse over the immediate Expr children in a RecordField.
functionBindingExprs :: Applicative f => (Expr s a -> f (Expr s b)) -> FunctionBinding s a -> f (FunctionBinding s b) Source #
Traverse over the immediate Expr children in a FunctionBinding.
Let-blocks
wrapInLets :: Foldable f => f (Binding s a) -> Expr s a -> Expr s a Source #
Wrap let-Bindings around an Expr.
wrapInLets can be understood as an inverse for multiLet:
let MultiLet bs e1 = multiLet b e0 wrapInLets bs e1 == Let b e0
This type represents 1 or more nested Let bindings that have been
coalesced together for ease of manipulation
Miscellaneous
internalError :: Text -> forall b. b Source #
Utility function used to throw internal errors that should never happen (in theory) but that are not enforced by the type system
reservedIdentifiers :: HashSet Text Source #
The set of reserved identifiers for the Dhall language | Contains also all keywords from "reservedKeywords"
escapeText :: Text -> Text Source #
Escape a Text literal using Dhall's escaping rules
Note that the result does not include surrounding quotes
pathCharacter :: Char -> Bool Source #
Returns True if the given Char is valid within an unquoted path
component
