Idris.Core.TT
Description
TT is the core language of Idris. The language has:
- Full dependent types
- A hierarchy of universes, with cumulativity: Type : Type1, Type1 : Type2, ...
- Pattern matching letrec binding
- (primitive types defined externally)
Some technical stuff:
- Typechecker is kept as simple as possible - no unification, just a checker for incomplete terms.
- We have a simple collection of tactics which we use to elaborate source programs with implicit syntax into fully explicit terms.

All binding forms are represented in a uniform fashion. This type only represents
the types of bindings (and their values, if any); the attached identifiers are part
of the Bind constructor for the TT type.
Constructors
| Lam | A function binding |
Fields

| Pi | A binding that occurs in a function type
expression, e.g. |
Fields
| |
| Let | A binding that occurs in a |
Fields
| |
| NLet | NLet is an intermediate product in the evaluator that's used for temporarily naming locals during reduction. It won't occur outside the evaluator. |
| Hole | A hole in a term under construction in the elaborator. If this is not filled during elaboration, it is an error. |
Fields
| |
| GHole | A saved TT hole that will later be converted to a top-level Idris metavariable applied to all elements of its local environment. |
Fields
| |
| Guess | A provided value for a hole. It will later be substituted - the guess is to keep it computationally inert while working on other things if necessary. |
| PVar | A pattern variable (these are bound around terms that make up pattern-match clauses) |
Fields

identifiers used for bindings and explicit named references;
usually we use TT .Name

allTTNames :: Eq n => TT n -> [n] #
bindAll :: [(n, Binder (TT n))] -> TT n -> TT n #
Introduce a Bind into the given term for each element of the
given list of (name, binder) pairs.
Arguments
| :: Name | ^ the bound name |
| -> Bool | ^ whether the name is implicit |
| -> Doc OutputAnnotation |
Pretty-printer helper for the binding site of a name
constIsType :: Const -> Bool #
Determines whether the input constant represents a type
deleteDefExact :: Name -> Ctxt a -> Ctxt a #
emptyContext :: Map k a #
explicitNames :: TT n -> TT n #
Replace all non-free de Bruijn references in the given term with references to the name of their binding.
Determine whether the first argument is completely contained in the second
finalise :: Eq n => TT n -> TT n #
Replace every non-free reference to the name of a binding in the given term with a de Bruijn index.
getArgTys :: TT n -> [(n, TT n)] #
Return a list of pairs of the names of the outermost Pi-bound
variables in the given term, together with their types.
substRetTy :: TT n -> TT n #
As getRetTy but substitutes names for de Bruijn indices
implicitable :: Name -> Bool #
instantiate :: TT n -> TT n -> TT n #
Replace the outermost (index 0) de Bruijn variable with the given term
internalNS :: String #
isInjective :: TT n -> Bool #
A term is injective iff it is a data constructor, type constructor, constant, the type Type, pi-binding, or an application of an injective term.
isTypeConst :: Const -> Bool #
lookupCtxt :: Name -> Ctxt a -> [a] #
lookupCtxtExact :: Name -> Ctxt a -> Maybe a #
lookupCtxtName :: Name -> Ctxt a -> [(Name, a)] #
Look up a name in the context, given an optional namespace. The name (n) may itself have a (partial) namespace given.
Rules for resolution:
- if an explicit namespace is given, return the names which match it. If none match, return all names.
- if the name has has explicit namespace given, return the names which match it and ignore the given namespace.
- otherwise, return all names.
mkApp :: TT n -> [TT n] -> TT n #
Returns a term representing the application of the first argument (a function) to every element of the second argument.
nativeTyWidth :: NativeTy -> Int #
noOccurrence :: Eq n => n -> TT n -> Bool #
Returns true if V 0 and bound name n do not occur in the term
occurrences :: Eq n => n -> TT n -> Int #
Return number of occurrences of V 0 or bound name i the term
pEraseType :: TT n -> TT n #
Arguments
| :: [Name] | Bound names, for highlighting |
| -> Raw | The term to pretty-print |
| -> Doc OutputAnnotation |
Pretty-print a raw term.
Arguments

| -> TT Name | The term to be printed |
| -> Doc OutputAnnotation |
Pretty-print a term

substNames :: Eq n => [(n, TT n)] -> TT n -> TT n #
As subst, but takes a list of (name, substitution) pairs instead
of a single name and substitution
Replaces all terms equal (in the sense of (==)) to
the old term with the new term.
substV :: TT n -> TT n -> TT n #
As instantiate, but also decrement the indices of all de Bruijn variables
remaining in the term, so that there are no more references to the variable
that has been substituted.
Return True if the argument Name should be interpreted as the name of a
interface.
termSmallerThan :: Int -> Term -> Bool #
Hard-code a heuristic maximum term size, to prevent attempts to serialize or force infinite or just gigantic terms
