normaliseC :: Context -> Env -> TT Name -> TT Name Source #
Normalise fully type checked terms (so, assume all names/let bindings resolved)
normaliseAll :: Context -> Env -> TT Name -> TT Name Source #
Normalise everything, whether abstract, private or public
normaliseBlocking :: Context -> Env -> [Name] -> TT Name -> TT Name Source #
As normaliseAll, but with an explicit list of names *not* to reduce
rt_simplify :: Context -> Env -> TT Name -> TT Name Source #
Simplify for run-time (i.e. basic inlining)
simplify :: Context -> Env -> TT Name -> TT Name Source #
Like normalise, but we only reduce functions that are marked as okay to inline, and lets
inlineSmall :: Context -> Env -> TT Name -> TT Name Source #
Like simplify, but we only reduce functions that are marked as okay to inline, and don't reduce lets
unfold :: Context -> Env -> [(Name, Int)] -> TT Name -> TT Name Source #
Unfold the given names in a term, the given number of times in a stack. Preserves 'let'. This is primarily to support inlining of the given names, and can also help with partial evaluation by allowing a rescursive definition to be unfolded once only. Specifically used to unfold definitions using interfaces before going to the totality checker (otherwise mutually recursive definitions in implementations will not work...)
A definition is either a simple function (just an expression with a type), a constant, which could be a data or type constructor, an axiom or as an yet undefined function, or an Operator. An Operator is a function which explains how to reduce. A CaseOp is a function defined by a simple case tree

Instances
Contexts used for global definitions and for proof state. They contain universe constraints and existing definitions. Also store maximum RigCount of the name (can't bind a name at multiplicity 1 in a RigW, for example)
initContext :: Context Source #
The initial empty context
setInjective :: Name -> Injectivity -> Context -> Context Source #
setMetaInformation :: Name -> MetaInformation -> Context -> Context Source #
addCasedef :: Name -> ErasureInfo -> CaseInfo -> Bool -> SC -> Bool -> Bool -> [(Type, Bool)] -> [Int] -> [Either Term (Term, Term)] -> [([Name], Term, Term)] -> [([Name], Term, Term)] -> Type -> Context -> TC Context Source #
simplifyCasedef :: Name -> [Name] -> [[Name]] -> ErasureInfo -> Context -> TC Context Source #
lookupTyName :: Name -> Context -> [(Name, Type)] Source #
Get the list of pairs of fully-qualified names and their types that match some name
lookupTyNameExact :: Name -> Context -> Maybe (Name, Type) Source #
Get the pair of a fully-qualified name and its type, if there is a unique one matching the name used as a key.
lookupTyExact :: Name -> Context -> Maybe Type Source #
Get the single type that matches some name precisely
lookupDefAcc :: Name -> Bool -> Context -> [(Def, Accessibility)] Source #
lookupDefAccExact :: Name -> Bool -> Context -> Maybe (Def, Accessibility) Source #
lookupInjectiveExact :: Name -> Context -> Maybe Injectivity Source #
lookupMetaInformation :: Name -> Context -> [MetaInformation] Source #
isCanonical :: Type -> Context -> Bool Source #
Return true if the given type is a concrete type familyor primitive False it it's a function to compute a type or a variable
isDConName :: Name -> Context -> Bool Source #
Check whether a resolved name is certainly a data constructor
canBeDConName :: Name -> Context -> Bool Source #
Check whether any overloading of a name is a data constructor
A HOAS representation of values
Minimal complete definition
uniqueNameCtxt :: Context -> Name -> [Name] -> Name Source #
Create a unique name given context and other existing names
isUniverse :: Term -> Bool Source #
