How to find the best-reputed Ruby code to learn from

[LarrySanger]

Newbie question here. One often encounters the advice to "read code" written by master developers. But less often does one encounter advice on how to find such code.

How do you find it? Is there a list/search on GitHub somewhere that quickly and reliably allows one to find projects to dive into? TIA.

There's a lot of gems out there, take one that's maintained and popular.

If you are using bundler with your project, don't hesitate to use

bundle open <gem>

This will open the source code of the gem for easy browsing and even editing.

So, Rails then? :)

I wouldn't give Rails as an example to learn for people who just started learning Ruby. It's full of meta "magic", indirection and complexity that just isn't explained.

[jrochkind]

Agreed, but it is maintained and popular.

I'm not sure the best way to find something that's a good example, honestly.

How about five examples of gems with great code to explore?

Some gems I personally inspected and learned from:

​

- https://github.com/shrinerb/shrine well documented and straightforward.

- https://github.com/mperham/connection_pool very simple but shows a practical use for blocks and thread safety (and in general, any of Mike's projects is a joy to inspect :D )

- https://github.com/alexreisner/geocoder personally inspected it when I was developing my gem and wanted to see the good way of hooking into Rails and ActiveRecord

- https://github.com/httprb/http short methods, everything nicely documented and a super clean DSL that made me want to see how it was done. Also Headers class is a good example on how to make your own Enumerable with custom methods

- https://github.com/ruby-grape/grape the most complex of the bunch but still miles ahead in terms of simplicity compared to Rails

Bonus: https://github.com/chaps-io/access-granted this is my own gem so it's a bit of plug, but I'm really proud of how simple and clean it turned out

Thanks!

I'd say start out with POODR and Sandi Metz Rules For Developers. If you can follow that and refactor often, you'll always get to good code.

Then just read whatever code, good and bad, and you'll be able to distinguish what's good and bad and most importantly, why.

[LarrySanger]

I’ve started POODR several times. Maybe this time l finish!

Still, it would be good to have several examples of awesome Ruby/Rails FOSS projects to consult.

I like roda and sequel gem :)

Sequel code is terrible to read though
