Why Another Generator?

Code generation has been becoming a popular way of metaprogramming in Go.

For example, when working with a ORM framework, you may want to create models with a given database schema with json tag support. it's trivial and burdensome when it comes with a database with hundreds even thousands of tables.

A code generation tool can help on this kind of issues through retriving database schema and rendering templates to go code.

However, before it turns into reality, you'll have to build a tool to

• reading and organizing templates properly
• formating the generated source code
• fixing imports, especially removing unused imports
• handle relative imports(imports among the generated code)
• naming of generated file names

Today, generators are handling code generation in their own ways, which means that you can not generate models of Beego ORM with generators or gorm. It doesn't make sense to build a new generator becuase those models are generated from the same database schema.

Genus provides a clean way to perform code generation. Go to Examples to see more details.
