CodeGen is a Jython code generation utility that facilitates code generation
into any output language. It's primary templating language is StringTemplate
V4, which is why CodeGen is in Jython and not
regular python. StringTemplate is a very clean templating language that
enforces rather strict separation of your template's model and the template
itself (the view). It also handles whitespace very inteligently, unlike many
templating libs out there, which is very important for code generation -- you
want your code to be human readable even if it is automatically created.
Features
- Custom Sections - Sometimes when you are dealing with templates that render to multiple files, you want to tweak the final output code of a particular rendered file by a little bit. You can generally always do it by adding additional fields to your model, but that can increase the complexity of your templates quite a bit. An alternative is to specify special sections in the template where custom code can be entered and preserved across renderings. This adds quite a bit of flexibility to your templates, at the expense of a slight bit of ugliness with the custom section delimiters.
