AGENDA
- Learning to Read
- Under the Hood of Rails
- Walkthrough: Writing a DSL
- Review
Learning by Reading
- Reading code effectively is a critical skill
- Concise code is great, but we need to be able to read anything we see so we can:
- Understand what is going on
- Extend / refactor / rewrite code as necessary
- Learn new syntax & techniques
- The Rails framework is some of the best Ruby code out there
- Reading it is a great learning tool!
UNDER THE HOOD OF RAILS
- Let's take a deeper dive into some Rails code
- We expect to be confused. A lot.
- Our goal is to know enough to navigate through it
- Then, we will follow the general example to build our own
DSL?
- DSL: Domain Specific Language
- Ideal way to simplify your code and enable code reuse
- Let's build a simple DSL to help us serialize an array w/ Redis
- The DSL's API should be the same as an array
- It should be simple and easy to drop in (gem-worthy!)
LET'S BUILD
Time to write a DSL!
REVIEW
- Reading code is a great way to learn
- Ruby is dynamic & powerful; use it!
- Remember to test :)
- Share your code
THANKS!
