Htcc.Parser.ConstructionData.Scope.ManagedScope

Description

The Data type of variables and its utilities used in parsing

Synopsis

class ManagedScope a where
- lookup :: Text -> Map Text a -> Maybe a
- fallBack :: Map Text a -> Map Text a -> Map Text a
- initial :: Map Text a
type ASTError i = (Text, TokenLC i)

Documentation

class ManagedScope a where Source #

Type classes common to concepts managed in scope

Methods

lookup :: Text -> Map Text a -> Maybe a Source #

lookup searches for something managed by the scope by the specified Text from a.

fallBack :: Map Text a -> Map Text a -> Map Text a Source #

Organize a list state after scoping.

initial :: Map Text a Source #

Helper function representing an empty something managed by the scope
