Variables ¶

var Prelude = &ast.Source{
	Name:    "prelude.graphql",
	Input:   preludeGraphql,
	BuiltIn: true,
}

Functions ¶

func AddRule ¶

func AddRule(name string, ruleFunc RuleFunc)

AddRule adds a rule to the rule set. ruleFunc is called once each time `Validate` is executed.

func IsValidFloatString ¶

func IsValidFloatString(val reflect.Value, kind reflect.Kind) bool

func IsValidIntString ¶

func IsValidIntString(val reflect.Value, kind reflect.Kind) bool

func LoadSchema ¶

func LoadSchema(inputs ...*Source) (*Schema, error)

func OrList ¶

func OrList(items ...string) string

Given [ A, B, C ] return 'A, B, or C'.

func QuotedOrList ¶

func QuotedOrList(items ...string) string

Given [ A, B, C ] return '"A", "B", or "C"'.

func RemoveRule ¶

func RemoveRule(name string)

RemoveRule removes an existing rule from the rule set if one of the same name exists. The rule set is global, so it is not safe for concurrent changes

func ReplaceRule ¶

func ReplaceRule(name string, ruleFunc RuleFunc)

ReplaceRule replaces an existing rule from the rule set if one of the same name exists. If no match is found, it will add a new rule to the rule set. The rule set is global, so it is not safe for concurrent changes

func SuggestionList ¶

func SuggestionList(input string, options []string) []string

Given an invalid input string and a list of valid options, returns a filtered list of valid options sorted based on their similarity with the input.

func Validate ¶

func Validate(schema *Schema, doc *QueryDocument, rules ...Rule) gqlerror.List

func ValidateSchemaDocument ¶

func ValidateSchemaDocument(sd *SchemaDocument) (*Schema, error)

func VariableValues ¶

func VariableValues(schema *ast.Schema, op *ast.OperationDefinition, variables map[string]interface{}) (map[string]interface{}, error)

VariableValues coerces and validates variable values

func Walk ¶

func Walk(schema *ast.Schema, document *ast.QueryDocument, observers *Events)

Types ¶

type AddErrFunc ¶
