Better Know A Ruby Thing #4: Keyword Arguments

Last time on Better Know A Ruby Thing, we covered positional arguments, and now we’re going to move on to keyword arguments. I really did think this was going to be shorter than the last one, and then I got to the conversion between keyword and positional arguments, and then… well, it’s not shorter. (I know I said the next newsletter was going to be Conway’s Law, that’s coming, but this one moved along faster…)

Better Know A Ruby Thing #3: Positional Arguments

Ruby has three ways to pass information from a method call to a method definition: positional arguments, keyword arguments, and block arguments. Each of these ways has: A syntax to declare an argument of that type in a method definition A syntax to declare an argument of that type in a method call A class that can can be used to convert arbitrary objects into and out of method calls A text marker that is associated with that kind of argument, *, **, or &.

The Pickaxe is out and I am Happy

I am extremely excited to say that Programming Ruby 3.3, also known as The Pickaxe Book, is now done done, finished, completely available as an ebook, and winding its way to distributors to ship to people as a genuine physical book. The PDF and ePub versions of the book are available at Pragmatic’s website. The print book should be available wherever you get print books, including Amazon and Bookshop. I’ve talked in the past about what’s in the book, what’s new, and whether you should buy it.
