Functions

func CamelCase 

func CamelCase(s string) string

CamelCase returns the CamelCased name. If there is an interior underscore followed by a lower case letter, drop the underscore and convert the letter to upper case. There is a remote possibility of this rewrite causing a name collision, but it's so remote we're prepared to pretend it's nonexistent - since the C++ generator lowercases names, it's extremely unlikely to have two fields with different capitalizations. In short, _my_field_name_2 becomes XMyFieldName_2.

func CamelCaseSlice 

func CamelCaseSlice(elem []string) string

CamelCaseSlice is like CamelCase, but the argument is a slice of strings to be joined with "_".

func CreateDescriptorsFromProto 

func CreateDescriptorsFromProto(req *pluginpb.CodeGeneratorRequest) (descs []*desc.FileDescriptor, err error)

func GetRequestType 

func GetRequestType(rpcOpts *gqlpb.Rpc, svcOpts *gqlpb.Svc) gqlpb.Type

func GoCamelCase 

func GoCamelCase(s string) string

GoCamelCase camel-cases a protobuf name for use as a Go identifier.

If there is an interior underscore followed by a lower case letter, drop the underscore and convert the letter to upper case.

func GraphqlFieldOptions 

func GraphqlFieldOptions(opts proto.Message) *gqlpb.Field

func GraphqlMethodOptions 

func GraphqlMethodOptions(opts proto.Message) *gqlpb.Rpc

func GraphqlOneofOptions 

func GraphqlOneofOptions(opts proto.Message) *gqlpb.Oneof

func GraphqlServiceOptions 

func GraphqlServiceOptions(opts proto.Message) *gqlpb.Svc

func IsAny 

func IsAny(o *desc.MessageDescriptor) bool

TODO maybe not compare by strings

func IsEmpty 

func IsEmpty(o *desc.MessageDescriptor) bool

same isEmpty but for mortals

func SplitCamelCase 

func SplitCamelCase(src string) (entries []string)

Split splits the camelcase word and returns a list of words. It also supports digits. Both lower camel case and upper camel case are supported. For more info please check: http://en.wikipedia.org/wiki/CamelCase

Examples 

"" =>                     [""]
"lowercase" =>            ["lowercase"]
"Class" =>                ["Class"]
"MyClass" =>              ["My", "Class"]
"MyC" =>                  ["My", "C"]
"HTML" =>                 ["HTML"]
"PDFLoader" =>            ["PDF", "Loader"]
"AString" =>              ["A", "String"]
"SimpleXMLParser" =>      ["Simple", "XML", "Parser"]
"vimRPCPlugin" =>         ["vim", "RPC", "Plugin"]
"GL11Version" =>          ["GL", "11", "Version"]
"99Bottles" =>            ["99", "Bottles"]
"May5" =>                 ["May", "5"]
"BFG9000" =>              ["BFG", "9000"]
"BöseÜberraschung" =>     ["Böse", "Überraschung"]
"Two  spaces" =>          ["Two", "  ", "spaces"]
"BadUTF8\xe2\xe2\xa1" =>  ["BadUTF8\xe2\xe2\xa1"]

Splitting rules

  1. If string is not valid UTF-8, return it without splitting as single item array.
  2. Assign all unicode characters into one of 4 sets: lower case letters, upper case letters, numbers, and all other characters.
  3. Iterate through characters of string, introducing splits between adjacent characters that belong to different sets.
  4. Iterate through array of split strings, and if a given string is upper case: if subsequent string is lower case: move last character of upper case string to beginning of lower case string

func ToLowerFirst 

func ToLowerFirst(s string) string
