Given the name of a NullJson type T , and the name of a type Value go-nulljson will create a new self-contained Go source file implementing  The file is created in the same package and directory as the package that defines T, Key. It has helpful defaults designed for use with go generate.  For example, given this snippet,  running this command  in the same directory will create the file pill_nulljson.go, in package painkiller, containing a definition of  Typically this process would be run using go generate, like this:  With no arguments, it processes the package in the current directory. Otherwise, the arguments must name a single directory holding a Go package or a set of Go source files that represent a single Go package.  The -type flag accepts a comma-separated list of types so a single run can generate methods for multiple types. The default output file is t_string.go, where t is the lower-cased name of the first type listed. It can be overridden with the -output flag.
