Gojay code generator

This package provides a command line tool to generate gojay's marshaling and unmarshaling interface implementation for custom struct type(s)

Get started

go install github.com/francoispqt/gojay/gojay

Generate code

Basic command

The basic command is straightforward and easy to use:

cd $GOPATH/src/github.com/user/project
gojay -s . -p true -t MyType -o output.go

If you just want to the output to stdout, omit the -o flag.

Using flags
  • s Source file/dir path, can be a relative or absolute path
  • t Types to generate with all its dependencies (comma separated)
  • a Annotation tag used to read metadata (default: json)
  • o Output file (relative or absolute path)
  • p Pool to reuse object (using sync.Pool)

Examples:

  • Generate SomeType type in /tmp/myproj go package, write to file output.go:
gojay -s /tmp/myproj -t SomeType -o output.go
  • Generate type SomeType in file somegofile.go, with custom tag gojay, write to stdout:
gojay -s somegofile.go -a gojay -t SomeType

Generator tags

You can add tags to your structs to control:

  • the JSON key
  • skip a struct field
  • the use of omitempty methods for marshaling
  • timeFormat (java style data format)
  • timeLayout (golang time layout)
Example:
type A struct {
	Str          string     `json:"string"`
	StrOmitEmpty string     `json:"stringOrEmpty,omitempty"`
	Skip         string     `json:"-"`
	StartTime    time.Time  `json:"startDate" timeFormat:"yyyy-MM-dd HH:mm:ss"`
	EndTime      *time.Time `json:"endDate" timeLayout:"2006-01-02 15:04:05"`
}
