A style of ornamentation characterized by fanciful combinations of intertwined forms.
Grotesque is an implementation of GraphQL in Haskell. It is a work in progress. Currently it can parse and pretty-print GraphQL queries and schemas. For example:
:set -XOverloadedStrings
:module + Grotesque
let Right document = parseDocument "{ field }"
-- Document { documentValue =
-- [ DefinitionOperation OperationDefinition
-- { operationDefinitionOperationType = OperationTypeQuery
-- , operationDefinitionName = Nothing
-- , operationDefinitionVariableDefinitions = Nothing
-- , operationDefinitionDirectives = Nothing
-- , operationDefinitionSelectionSet = SelectionSet { selectionSetValue =
-- [ SelectionField Field
-- { fieldAlias = Nothing
-- , fieldName = Name { nameValue = "field" }
-- , fieldArguments = Nothing
-- , fieldDirectives = Nothing
-- , fieldSelectionSet = Nothing } ] } } ] }
prettyPrintDocument document
-- "query {field}"If you're looking for a production-ready implementation, check out the reference implementation in JavaScript or the C++ query parser.
