Fixed
- Location of a parse error is returned in a singleton array with key
locations.
- Parsing comments in the front of definitions.
- Some missing labels were added to the parsers, some labels were fixed to
refer to the AST nodes being parsed.
Added
AST reexports AST.Parser.AST.Document.Location is a token location as a line and column pair.Execute reexports Execute.Coerce.Error.Error is an error representation with a message and source location.Error.Response represents a result of running a GraphQL query.Type.Schema exports Type which lists all types possible in the schema.- Parsing subscriptions.
Error.ResponseEventStream, Type.Out.Resolve, Type.Out.Subscribe and
Type.Out.SourceEventStream define subscription resolvers.Error.ResolverException is an exception that can be thrown by (field value
and event stream) resolvers to signalize an error. Other exceptions will
escape.Test.Hspec.GraphQL contains some test helpers.Validate contains the validator and standard rules.
Changed
Type.Out.Resolver: Interface fields don't have resolvers, object fields
have value resolvers, root subscription type resolvers need an additional
resolver that creates an event stream. Resolver represents these differences
now and pairs a field with the function(s). Resolvers don't have ExceptT,
errors are handled with MonadThrow/MonadCatch.- All code from
Trans is moved to Type.Out and exported by Type and
Type.Out.
AST.Core contained only Arguments which was moved to Type.Definition.
AST provides now only functionality related to parsing and encoding, as it
should be.Execute.execute takes an additional argument, a possible operation name
and returns either a stream or the response.Error module was changed to work with dedicated types for errors and the
response instead of JSON.graphqlSubs takes an additional argument, the operation name. The type of
variable names is changed back to JSON since it is a common format and it
saves additional conversions. Custom format still can be used with the
underlying functions (in the Execute module). The function returns either a
a stream or the resolved value.graphql returns either a stream or the resolved value.- The constraint of the base monad was changed to
MonadCatch (and it implies
MonadThrow).
Removed
Trans.ActionT is an unneeded layer of complexity. Type.Out.Resolver
represents possible resolver configurations.Execute.executeWithName. Execute.execute takes the operation name and
completely replaces executeWithName.
