Change Log

All notable changes to this project will be documented in this file.

0.6.1.0 - 2019-12-23

Fixed

• Parsing multiple string arguments, such as login(username: "username", password: "password") would fail on the comma due to strings not having a space consumer.
• Fragment spread is evaluated based on the __typename resolver. If the resolver is missing, it is assumed that the type condition is satisfied (all fragments are included).
• Escaping characters during encoding.

Added

• Directive support (@skip and @include).
• Pretifying multi-line string arguments as block strings.

0.6.0.0 - 2019-11-27

Changed

• Language.GraphQL.Encoder moved to Language.GraphQL.AST.Encoder.
• Language.GraphQL.Parser moved to Language.GraphQL.AST.Parser.
• Language.GraphQL.Lexer moved to Language.GraphQL.AST.Lexer.
• All Language.GraphQL.AST.Value data constructor prefixes were removed. The module should be imported qualified.
• All Language.GraphQL.AST.Core.Value data constructor prefixes were removed. The module should be imported qualified.
• Language.GraphQL.AST.Core.Object is now just a HashMap.
• Language.GraphQL.AST.Transform is isn't exposed publically anymore.
• Language.GraphQL.Schema.resolve accepts a selection Seq (Data.Sequence) instead of a list. Selections are stored as sequences internally as well.
• Add a reader instance to the resolver's monad stack. The Reader contains a Name/Value hashmap, which will contain resolver arguments.

Added

• Nested fragment support.

Fixed

• Consume ignored tokens after $ and !. I mistakenly assumed that $variable is a single token, same as Type! is a single token. This is not the case, for example Variable is defined as $ Name, so these are two tokens, therefore whitespaces and commas after $ and ! should be consumed.

Improved

• Language.GraphQL.AST.Parser.type_: Try type parsers in a variable definition in a different order to avoid using but.

Removed

• Language.GraphQL.AST.Arguments. Use [Language.GraphQL.AST.Argument] instead.
• Language.GraphQL.AST.Directives. Use [Language.GraphQL.AST.Directives] instead.
• Language.GraphQL.AST.VariableDefinitions. Use [Language.GraphQL.AST.VariableDefinition] instead.
• Language.GraphQL.AST.FragmentName. Use Language.GraphQL.AST.Name instead.
• Language.GraphQL.Execute.Schema - It was a resolver list, not a schema.
• Language.GraphQL.Schema: enum, enumA, wrappedEnum and wrappedEnumA. Use scalar, scalarA, wrappedScalar and wrappedScalarA instead.

0.5.1.0 - 2019-10-22

Deprecated

• Language.GraphQL.AST.Arguments. Use [Language.GraphQL.AST.Argument] instead.
• Language.GraphQL.AST.Directives. Use [Language.GraphQL.AST.Directives] instead.
• Language.GraphQL.AST.VariableDefinitions. Use [Language.GraphQL.AST.VariableDefinition] instead.

Added

• Module documentation.
• Inline fragment support.

Fixed

• Top-level fragments.
• Fragment for execution is chosen based on the type.

0.5.0.1 - 2019-09-10

Added

• Minimal documentation for all public symbols.

Deprecated

• Language.GraphQL.AST.FragmentName. Replaced with Language.GraphQL.AST.Name.
• Language.GraphQL.Execute.Schema - It is not a schema (at least not a complete one), but a resolver list, and the resolvers should be provided by the user separately, because the schema can originate from a GraphQL document. Schema name should be free to provide a data type for the real schema later.
• Language.GraphQL.Schema: enum, enumA, wrappedEnum and wrappedEnumA. There are actually only two generic types in GraphQL: Scalars and objects. Enum is a scalar value.

Fixed

• Parsing block string values.

0.5.0.0 - 2019-08-14

Added

• executeWithName executes an operation with the given name.
• Export Language.GraphQL.Encoder.definition, Language.GraphQL.Encoder.type' and Language.GraphQL.Encoder.directive.
• Export Language.GraphQL.Encoder.value. Escapes \ and " in strings now.

Changed

• Operation includes now possible operation name which allows to support documents with multiple operations.
• Language.GraphQL.Encoder.document and other encoding functions take a Formatter as argument to distinguish between minified and pretty printing.
• All encoder functions return Data.Text.Lazy.

Removed

• Unused Language.GraphQL.Encoder.spaced.

0.4.0.0 - 2019-07-23

Added

• Support for mutations.
• Error handling (with monad transformers).
• Nullable types.
• Arbitrary nested lists support.
• Potential BOM header parsing.

Changed

• attoparsec is replaced with megaparsec.
• The library is now under Language.GraphQL (instead of Data.GraphQL).
• HUnit and tasty are replaced with Hspec.
• Alternative/MonadPlus resolver constraints are replaced with MonadIO.

Removed

• Duplicates from Language.GraphQL.AST already available in Language.GraphQL.AST.Core.
• All module exports are now explicit, so private and help functions aren't exported anymore.

0.3 - 2015-09-22

Changed

• Exact match numeric types to spec.
• Names follow now the spec.
• AST slightly different for better readability or easier parsing.
• Replace golden test for test to validate parsing/encoding.

Added

• Parsing errors in all cases where Alternative is used.
• GraphQL encoder.

Fixed

• Expect braces inputValueDefinitions instead of parens when parsing.

0.2.1 - 2015-09-16

Fixed

• Include data files for golden tests in Cabal package.
• Support for ghc-7.8.

0.2 - 2015-09-14

Added

• Rudimentary parser for GraphQL which successfully parses the sample file kitchen-sink.graphql from graphql-js tests.
• Golden test for kitchen-sink.grahql parsing.

Changed

• Many optional data types in GraphQl didn't need to be wrapped in a Maybe.
• Some newtypes became type synonyms for easier parsing.

0.1 - 2015-09-12

Added

• Data types for the GraphQL language.
