shorten result print for struct generated by protobuf

[learningpro]

if an object has a type generated by protobuf, then the pp.Print() will show very very very long content on screen.

It would be better to show the user-defined fields.

Can you share an example code (ideally a repository) to reproduce your current situation, the output it currently generates, a proposed API you'd like to use, and the output it would generate?

Sure. I found a repo in Github. https://github.com/kfelter/protobuf-example/tree/main The steps are:

1. clone this repo and edit main.go
2. add "github.com/k0kubun/pp" in import
3. add pp.Println(events) at the end of main function.
4. run go mod tidy and go build , it will generate a binary protobuf-example
5. run ./protobuf-example and there will be a very very long output like this:

Thanks for providing:

can you also provide the other part?:

a proposed API you'd like to use, and the output it would generate

As of now, only you can guess what you want, so only you can implement this feature. I can review a pull request if writing it is easier than doing the above.

@k0kubun I don't know how pp get each field, Could you point out which piece of code I should refer to and learn from. Than I may create a PR for it.

This is the place where pp gets each field: https://github.com/k0kubun/pp/blob/6f55b4dc4b268e1f0c695978898e5bb3f901c322/printer.go#L235-L249
