Agda.Syntax.Abstract.Name

Description

Abstract names should carry unique identifiers and stuff. Not right now though.

Synopsis

Documentation

data Name Source

A name is a unique identifier and a suggestion for a concrete name. The concrete name contains the source location (if any) of the name. The source location of the binding site is also recorded.

data QName Source

Qualified names are non-empty lists of names. Equality on qualified names are just equality on the last name, i.e. the module part is just for show.

The SetRange instance for qualified names sets all individual ranges (including those of the module prefix) to the given one.

Constructors

QName 

newtype AmbiguousQName Source

Ambiguous qualified names. Used for overloaded constructors.

Invariant: All the names in the list must have the same concrete, unqualified name.

Constructors

AmbQ 

Fields

unAmbQ :: [QName]
 

withRangesOf :: ModuleName -> [Name] -> ModuleNameSource

Sets the ranges of the individual names in the module name to match those of the corresponding concrete names. If the concrete names are fewer than the number of module name name parts, then the initial name parts get the range noRange.

C.D.E withRangesOf [A, B] returns C.D.E but with ranges set as follows:

  • C: noRange.
  • D: the range of A.
  • E: the range of B.

Precondition: The number of module name name parts has to be at least as large as the length of the list.

withRangesOfQ :: ModuleName -> QName -> ModuleNameSource

Like withRangesOf, but uses the name parts (qualifier + name) of the qualified name as the list of concrete names.

mkName :: Range -> NameId -> String -> NameSource

The Range sets the definition site of the name, not the use site.

qnameToConcrete :: QName -> QNameSource

Turn a qualified name into a concrete name. This should only be used as a fallback when looking up the right concrete name in the scope fails.

toTopLevelModuleName :: ModuleName -> TopLevelModuleNameSource

Computes the TopLevelModuleName corresponding to the given module name, which is assumed to represent a top-level module name.

Precondition: The module name must be well-formed.

isOperator :: QName -> BoolSource

Is the name an operator?

nextName :: Name -> NameSource

Get the next version of the concrete name. For instance, nextName x = x'. The name must not be a NoName.
