gqlr (development version)

gqlr 0.1.0

execute_request() now requires operation_name, variables, and initial_value to be named arguments, as ... has been added ahead of these parameters (#11).
server() now requires log and initial_value to be named arguments, as ... has been added ahead of these parameters (#11).
server()'s / route now redirects to /graphiql only when graphiql = TRUE (#11).

execute_request() gains a verbose_errors argument. When TRUE, error-like messages are displayed in real time. By default, this is TRUE when run interactively (#11).
server() now supports GraphiQL, an interactive GraphQL IDE. To view the GraphiQL interface, run gqlr::server(MY_SCHEMA, graphiql = TRUE) and visit http://localhost:8000/graphiql/. By default, GraphiQL support is only enabled when run interactively (#11).

The pryr package dependency has been removed, as the package is being archived. Required functions (modify_lang(), make_function(), unenclose(), substitute_q()) have been copied into the package (#16).
Introspection now correctly returns subscriptionType as NULL to indicate that subscriptions are not supported (#11).
Mutation execution now correctly uses the mutation operation for validation, rather than incorrectly using the query operation (#9).
The __typename meta field is no longer attached to object structures (#11).
