parser is used by [gqlgen](https://github.com/99designs/gqlgen), and it should be reasonablly stable. + +Guiding principles: + + - maintainability: It should be easy to stay up to date with the spec + - well tested: It shouldnt need a graphql server to validate itself. Changes to this repo should be self contained. + - server agnostic: It should be usable by any of the graphql server implementations, and any graphql client tooling. + - idiomatic & stable api: It should follow go best practices, especially around forwards compatibility. + - fast: Where it doesnt impact on the above it should be fast. Avoid unnecessary allocs in hot paths. + - close to reference: Where it doesnt impact on the above, it should stay close to the [graphql/graphql-js](github.com/graphql/graphql-js) reference implementation. diff --git a/vendor/github.com/vektah/gqlparser/validator/error.go b/vendor/github.com/vektah/gqlparser/validator/error.go new file mode 100644 index 00000000..f354dee5 --- /dev/null +++ b/vendor/github.com/vektah/gqlparser/validator/error.go @@ -0,0 +1,55 @@ +package validator + +import ( + "fmt" + + "github.com/vektah/gqlparser/ast" + "github.com/vektah/gqlparser/gqlerror" +) + +type ErrorOption func(err *gqlerror.Error) + +func Message(msg string, args ...interface{}) ErrorOption { + return func(err *gqlerror.Error) { + err.Message += fmt.Sprintf(msg, args...) + } +} + +func At(position *ast.Position) ErrorOption { + return func(err *gqlerror.Error) { + if position == nil { + return + } + err.Locations = append(err.Locations, gqlerror.Location{ + Line: position.Line, + Column: position.Column, + }) + if position.Src.Name != "" { + err.SetFile(position.Src.Name) + } + } +} + +func SuggestListQuoted(prefix string, typed string, suggestions []string) ErrorOption { + suggested := SuggestionList(typed, suggestions) + return func(err *gqlerror.Error) { + if len(suggested) > 0 { + err.Message += " " + prefix + " " + QuotedOrList(suggested...) + "?" + } + } +} + +func SuggestListUnquoted(prefix string, typed string, suggestions []string) ErrorOption { + suggested := SuggestionList(typed, suggestions) + return func(err *gqlerror.Error) { + if len(suggested) > 0 { + err.Message += " " + prefix + " " + OrList(suggested...) + "?" + } + } +} + +func Suggestf(suggestion string, args ...interface{}) ErrorOption { + return func(err *gqlerror.Error) { + err.Message += " Did you mean " + fmt.Sprintf(suggestion, args...) + "?" + } +} diff --git a/vendor/github.com/vektah/gqlgen/neelance/tests/testdata/LICENSE b/vendor/github.com/vektah/gqlparser/validator/imported/LICENSE index fce4519e..fce4519e 100644 --- a/vendor/github.com/vektah/gqlgen/neelance/tests/testdata/LICENSE +++ b/vendor/github.com/vektah/gqlparser/validator/imported/LICENSE diff --git a/vendor/github.com/vektah/gqlparser/validator/messaging.go b/vendor/github.com/vektah/gqlparser/validator/messaging.go new file mode 100644 index 00000000..f1ab5873 --- /dev/null +++ b/vendor/github.com/vektah/gqlparser/validator/messaging.go @@ -0,0 +1,39 @@ +package validator + +import "bytes" + +// Given [ A, B, C ] return '"A", "B", or "C"'. +func QuotedOrList(items ...string) string { + itemsQuoted := make([]string, len(items)) + for i, item := range items { + itemsQuoted[i] = `"` + item + `"` + } + return OrList(itemsQuoted...) +} + +// Given [ A, B, C ] return 'A, B, or C'. +func OrList(items ...string) string { + var buf bytes.Buffer + + if len(items) > 5 { + items = items[:5] + } + if len(items) == 2 { + buf.WriteString(items[0]) + buf.WriteString(" or ") + buf.WriteString(items[1]) + return buf.String() + } + + for i, item := range items { + if i != 0 { + if i == len(items)-1 { + buf.WriteString(", or ") + } else { + buf.WriteString(", ") + } + } + buf.WriteString(item) + } + return buf.String() +} diff --git a/vendor/github.com/vektah/gqlparser/validator/prelude.go b/vendor/github.com/vektah/gqlparser/validator/prelude.go new file mode 100644 index 00000000..80ce8a21 --- /dev/null +++ b/vendor/github.com/vektah/gqlparser/validator/prelude.go @@ -0,0 +1,5 @@ +package validator + +import "github.com/vektah/gqlparser/ast" + +var Prelude = &ast.Source{Name: "prelude.graphql", Input: "# This file defines all the implicitly declared types that are required by the graphql spec.
