Refactoring Generator of Source Code for Scala

"Refactoring" because it does not blindly overwrite previously generated files.
It only changes what it needs to.

This means you can add your own code into the generated one, as long as it does not clash with it. The goal is to have a minimally intrusive code generator.

It is best if you use it in combination with Scalafmt, to minimize the git diff.

See the example folder

Regenesca is based on Scalameta.

The principle is simple.
You tell it what source code should be contained in a particular file, and then:

• if file doesn't exist -> write that code into it
• if file exists -> merge the existing scala code in a mostly ad-hoc way to achieve 99% of what you wanted with your code generator

The merge looks roughly as follows:

• same-named class -> merge their contents
• same-named object -> merge their contents
• same-named enum -> overwrite it completely
• same-named type -> overwrite it completely
• same-named val/var -> overwrite it completely
• same-named def -> merge internally OR overwrite it completely (global flag)
• import is added if a same one doesn't exist
• cases are merged by their patterns
• comments are not preserved
• it ignores expressions when merging
