Fixed
- The parser rejects variables when parsing defaultValue (DefaultValue). The
specification defines default values as Value with const parameter and
constants cannot be variables. AST.Document.ConstValue was added,
AST.Document.ObjectField was modified.
- AST transformation should never fail.
- Arguments and fields with a missing variable as value should be left out.
- Invalid (recusrive or non-existing) fragments should be skipped.
- Argument value coercion.
- Variable value coercion.
- Result coercion.
- The executor should skip the fields missing in the object type and not fail.
- Merging subselections.
Changed
Schema.Resolver was moved to Type.Out, it is a field and resolver function
pair.AST.Core.Value was moved into Type.Definition. These values are used only
in the execution and type system, it is not a part of the parsing tree.Type module is superseded by Type.Out. This module contains now only
exports from other module that complete Type.In and Type.Out exports.Error.CollectErrsT contains the new Resolution data structure.
Resolution represents the state used by the executor. It contains all types
defined in the schema and collects the thrown errors.
Added
Type.Definition contains base type system definition, e.g. Enums and
Scalars.Type.Schema describes a schema. Both public functions that execute queries
accept a Schema now instead of a HashMap. The execution fails if the root
operation doesn't match the root Query type in the schema.Type.In and Type.Out contain definitions for input and output types.Execute.Coerce defines a typeclass responsible for input, variable value
coercion. It decouples us a bit from JSON since any format can be used to pass
query variables. Execution functions accept (HashMap Name a) instead of
Subs, where a is an instance of VariableValue.
Removed
Schema.scalar, Schema.wrappedScalar. They accepted everything can be
converted to JSON and JSON is not suitable as an internal representation for
GraphQL. E.g. GraphQL distinguishes between Floats and Integers.Schema.wrappedObject, Schema.object, Schema.resolversToMap. There is no
need in special functions to construct field resolvers anymore, resolvers are
normal functions attached to the fields in the schema representation.Schema.resolve is superseded by Execute.Execution.Error.runAppendErrs isn't used anywhere.AST.Core: Document, Directive, Field, Fragment, Selection, Alias
TypeCondition were modified, moved into Execute.Transform.Document and
made private. These types describe intermediate representation used by the
executor internally. Moving was required to avoid cyclic dependencies between
the executor and type system.AST.Core doesn't reexports anything.

Fixed
- Result of null encoding
- Block strings encoding
- Result of tab and newline encoding
Added
- AST for the GraphQL schema.
- Type system definition parser.
Trans.argument.- Schema extension parser.
- Contributing guidelines.
Schema.resolversToMap (intended to be used internally).
Changed
- Rename
AST.Definition into AST.Document.ExecutableDefinition.
AST.Document.TypeSystemDefinition and AST.Document.TypeSystemExtension
can also be definitions.
- Move all AST data to
AST.Document and reexport them.
- Rename
AST.OperationSelectionSet to AST.Document.SelectionSet.
- Make
Schema.Subs a Data.HashMap.Strict (was a function
key -> Maybe value before).
- Make
AST.Lexer.at a text (symbol) parser. It was a char before and is
symbol "@" now.
- Replace
MonadIO with a plain Monad. Since the tests don't use IO,
set the inner monad to Identity.
NonEmpty (Resolver m) is now HashMap Text (NonEmpty (Resolver m)). Root
operation type can be any type, therefore a hashmap is needed. Since types
cannot be empty, we save the list of resolvers in the type as a non-empty
list. Currently only "Query" and "Mutation" are supported as types. For more
schema support is required. The executor checks now if the type in the query
matches the type of the provided root resolvers.
Removed
AST.Field, AST.InlineFragment and AST.FragmentSpread.
These types are only used in AST.Selection and AST.Selection contains now
3 corresponding data constructors, Field, InlineFragment and
FragmentSpread, instead of separate types. It simplifies pattern matching
and doesn't make the code less typesafe.Schema.scalarA.Schema.wrappedScalarA.Schema.wrappedObjectA.Schema.objectA.AST.Argument. Replaced with AST.Arguments which holds all arguments as a
key/value map.

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.

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
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.

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.

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.
