Why Ruby Class Methods Resist Refactoring

Sasha Rezvina explores why class methods in Ruby are hard to refactor. They tend to accumulate lots of logic. I prefer limiting class methods to “builder” methods that instantiate new objects, like .initialize.

Verbal Expressions: Ruby Regular Expressions made easy

This looks like a fantastic library. It provides a way to “verbally” construct regular expressions:

tester = VerEx.new do
  start_of_line
  find 'http'
  maybe 's'
  find '://'
  maybe 'www.'
  anything_but ' '
  end_of_line
end

tester =~ "https://www.google.com"

It supports string replacement, and capture groups too!
