Documentation
A name is a non-empty list of alternating Id
s and Hole
s. A normal name
is represented by a singleton list, and operators are represented by a list
with Hole
s where the arguments should go. For instance: [Hole,Id "+",Hole]
is infix addition.
Equality and ordering on Name
s are defined to ignore range so same names
in different locations are equal.
Data type constructed in the Happy parser; converted to GenPart
before it leaves the Happy code.
LambdaHole RawName RawName | (x -> y) ; 1st argument is the bound name (unused for now) |
ExprHole RawName | simple named hole with hiding |
Part of a Notation
stringParts :: Notation -> [RawName] Source
Get a flat list of identifier parts of a notation.
holeTarget :: GenPart -> Maybe Int Source
Target argument position of a part (Nothing if it is not a hole)
isBindingHole :: GenPart -> Bool Source
isLambdaHole :: HoleName -> Bool Source
mkNotation :: [NamedArg c HoleName] -> [RawName] -> Either String Notation Source
From notation with names to notation with indices.
defaultNotation :: [t] Source
No notation by default
noNotation :: [t] Source
