Powerful Command-Line Applications in Go: Exercise Solutions (many pages)

Is there any place where we can discuss the solutions to some of the exercises? I can figure most of them out, but am having trouble with Chapter 2, 2nd and third exercise.

It would be great to also compare my solutions to that of an expert’s…

Hello @adamwoolhether ,

As per your suggestion I created a book club for the book. Let’s use it to share and discuss solutions to the exercises. I’ll post my solution to the exercise you mentioned to get it started.

Thanks @AstonJ and @Margaret for the help !

Thanks,
Ricardo

@AstonJ what would you suggest for readers to discuss solutions to exercises in the book? A book club perhaps? How do we go about setting that up? The author, @rgerardi, agrees it is a good idea.

@rgerardi would you feel comfortable with option 1, and if yes, do you want to set it up? That way it has your name associated with it from the start.
