2019-12-30Replace substitution function with a mapEugen Wissner
It makes using variables with queries more approachable, but some work still has to be done. - The type `Subs` should be renamed and moved out of `Schema`, together with `AST.Core.Value` probably. - Some kind of conversion should be possible from a user-defined input type T to the Value. So the final HashMap should have a type like `HashMap name a`, where a is an instance of a potential typeclass InputType.
2019-12-28Move AST to AST.DocumentEugen Wissner
2019-12-27Define schema AST.Eugen Wissner
Large parts of the schema aren't exported publically. They will be made public during writing the parser. Fixes #6.
2019-12-26Add definition moduleEugen Wissner
2019-12-25Replace AST.Selection data constructorsEugen Wissner
2019-12-21Pretify multi-line string arguments as block stringsEugen Wissner
Fixes #10.
2019-12-20Encode Unicode. Fix #34Eugen Wissner
2019-12-19Escape non-source characters in the encoderEugen Wissner
2019-12-18Move Execute.Directive to Type.DirectiveEugen Wissner
Just to roughly follow the structure of the reference implementation.
2019-12-07Move Transform to Language.GraphQL.ExecuteEugen Wissner
Language.GraphQL.AST.Transform is an internal module. Even though it works with the AST, it is a part of the execution process, it translates the original parser tree into a simpler one, so the executor has less work to do. Language.GraphQL.AST should contain only the parser and be independent from other packages, so it can be used on its own.
2019-12-06Support directives (skip and include)Eugen Wissner
Fixes #24.
2019-12-02Consider __typename when evaluating fragmentsEugen Wissner
Fixes #30.
2019-11-28Fix strings not consuming spacesSam Nolan
Fixes #28
2019-11-23Add a reader instance to the resolversEugen Wissner
The Reader contains a Name/Value hashmap, which will contain resolver arguments.
2019-11-22Try type parsers in a different orderEugen Wissner
2019-11-21Fix failed parsing on multiple required argumentsSam Nolan
Fixes #25.
2019-11-16Rewrite selections into a Sequence. Fix #21Eugen Wissner
2019-11-14Fail on cyclic fragments, fix #22Eugen Wissner
2019-11-12Support nested fragments in any orderEugen Wissner
Fix #19.
2019-11-09Support nested fragmentsEugen Wissner
... without forward lookup.
2019-11-07AST.Transform: Pass down a readerEugen Wissner
The reader contains variable substitution functions and fragments.
2019-11-03Move related modules to Language.GraphQL.ASTEugen Wissner
Fixes #18. - `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.Transform` is now isn't exposed publically anymore.
2019-11-02Propagate Maybe in the transform treeEugen Wissner
Since the transform tree can already find some errors, it may fail here and there. Almost all functions return a Maybe to signalize an error. Will be replaced with an Either of course.
2019-10-31Save fragments in a hash mapEugen Wissner
Fixes #20.
2019-10-25Remove deprecated functions and aliasesEugen Wissner
2019-10-19Handle top-level fragmentsEugen Wissner

Fixes #11.
2019-10-08Support inline fragments on typesEugen Wissner
2019-10-01Deprecate plural type aliasesEugen Wissner
Fixes #16. Deprecates: - Language.GraphQL.AST.Arguments - Language.GraphQL.AST.Directives - Language.GraphQL.AST.VariableDefinitions
2019-09-25Document undocumented modulesEugen Wissner
Fixes #15.
2019-09-20Fix haddoc warningsEugen Wissner
Fix #14.
2019-09-06Fix #12Eugen Wissner
2019-09-01Deprecate enum, enumA, wrappedEnum, wrappedEnumAEugen Wissner
These functions are from Language.GraphQL.Schema. There are actually only two generic types in GraphQL: Scalars and objects. Enum is a scalar value. According to the specification enums may be serailized to strings. And in the current implementation they used untyped strings anyway, so there is no point to have differently named functions with the same implementation as their scalar counterparts.
2019-08-30Deprecate Language.GraphQL.Execute.SchemaEugen Wissner
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.
2019-08-29Document all public symbols.Eugen Wissner
Mostly basic documentation. Fixes #4.
2019-08-26Provide more documentation on functions and typesEugen Wissner

Fixes #2.
2019-08-05Make all encoder functions return lazy textEugen Wissner
2019-08-03Implement indentation in the encoderEugen Wissner
2019-08-02Put spaces between tokens in the pretty printerEugen Wissner
2019-07-31Introduce formatter type for the encoderEugen Wissner
... to distinguish between minified and pretty printing.

2019-07-25Implement multiple operation supportEugen Wissner
2019-07-23Add singleError utility functionv0.4.0.0Eugen Wissner
2019-07-22Parse the BOM header if anyEugen Wissner
2019-07-19Report parse errors with line and column numbersEugen Wissner
2019-07-18Reuse common types from AST.CoreEugen Wissner
2019-07-14Make all exports explicitEugen Wissner
2019-07-08Constrain the resolvers with MonadIOEugen Wissner
This replaces the most usages of MonadPlus, which is not appropriate for the resolvers, since a resolver is unambiguously chosen by the name (no need for 'mplus'), and the resolvers are often doing IO.
