Creates Go source file of structs for use in some MySql database packages

struct-create

Creates Go source file of structs for use in some MySQL database packages. It uses go-sql-driver/mysql for querying the information_schema database. I created this for personal use, so it's not written for extensibility, but shouldn't be difficult to adapt for your own use.

Configuration may be set in the source file:

var defaults = Configuration{
	DbUser: "db_user",
	DbPassword: "db_pw",
	DbName: "bd_name",
	// PKG_NAME gives name of the package using the stucts
	PkgName: "DbStructs",
	// TAG_LABEL produces tags commonly used to match database field names with Go struct
	//members. This will be skipped if the string is empty.
	TagLabel: "db",
}

Or by a JSON file using the json flag struct-create --json=test.json

{
	"db_user": "db_user",
	"db_password": "db_pass",
	"db_name": "db_name",
	"pkg_name": "JsonTest",
	"tag_label": "db"
}
