This is a fantastic utility - kudos for taking the effort to build it. I was wondering if you would be open to the idea of providing this utility also as a library so that any other projects working with code generation can use this to format the generated code.

My use case is that I work on a no-code project where we generate a lot of go code for our customers. The generated code has a huge map which by default is rendered on the same line and is impossible to grok with naked eyes. So I wanted to introduce golines as one of the preprocessing step to break down the map into individual lines. Hence if this utility is available as a library- it would be super useful for me.

I am happy to provide a PR for this - but will require some refactoring and hence wanted to discuss before working on it.
