parse :: IsExpr e => (ParseSections, Parser e a) -> [e] -> [a] Source #

Runs a parser. If sections should be parsed, then identifiers with at least two name parts are split up into multiple tokens, using PositionInName to record the tokens' original positions within their respective identifiers.

Parser combinators

partP :: IsExpr e => [Name] -> RawName -> Parser e Range Source #

Parse a specific identifier as a NamePart

atLeastTwoParts :: IsExpr e => Parser e Name Source #

Parses a split-up, unqualified name consisting of at least two name parts.

The parser does not check that underscores and other name parts alternate. The range of the resulting name is the range of the first name part that is not an underscore.

patternBinder :: IsExpr e => Parser e Binder Source #

Parses a potentially pattern-matching binder

type family OperatorType (k :: NotationKind) e Source #

Used to define the return type of opP.

data NK (k :: NotationKind) where Source #

A singleton type for NotationKind (except for the constructor NoNotation).

Constructors

In :: NK 'InfixNotation
Pre :: NK 'PrefixNotation
Post :: NK 'PostfixNotation
Non :: NK 'NonfixNotation

opP :: forall e (k :: NotationKind). IsExpr e => ParseSections -> Parser e e -> NewNotation -> NK k -> Parser e (OperatorType k e) Source #

Parse the "operator part" of the given notation.

Normal holes (but not binders) at the beginning and end are ignored.

If the notation does not contain any binders, then a section notation is allowed.
