prmdg

prmd style JSON Hyper Schema to Go structs, and validators

Why created

Prerequisite

go get -u golang.org/x/tools/cmd/goimports

prmdg applies goimports to the ourput file.

Installation

go get -u github.com/achiku/prmdg

If you want to use github.com/gureg/null in Go struct by adding --nullable option, you need to install github.com/gureg/null first.
