Regular Expressions / Regular Expressions Anchors

Hey there! We're thoughtbot, a design and development consultancy that brings your digital product ideas to life. We also love to share what we learn.

This coding exercise comes from Upcase, the online learning platform we run. It's part of the Regular Expressions course and is just one small sample of all the great material available on Upcase, so be sure to visit and check out the rest.

Exercise Intro

Anchors in regular expressions are a powerful tool that allows you to be much more precise in what you match. Instead of matching "a" anywhere in a string, you can match "a" at the start or end of a string.

For more, check out the documentation.

Instructions

To start, you'll want to clone and run the setup script for the repo

git clone git@github.com:thoughtbot-upcase-exercises/regular-expressions-anchors.git
cd regular-expressions-anchors
bin/setup

First, run bin/setup.

Then, run rake to see the failing tests. You can run rake at any point to see the test results again.

Fill in the methods in lib/anchors.rb to make the tests pass.
