So here is a bit of a complicated ruby function

function4(
  function3(
    function2(
      function1,
      value,
    ),
    value,
 value,

  end
end

module SquareMethod
  def square(number)
    number * number

Automated Styleguide Enforcement

Why bother having a styleguide?
  - It gives your code a uniform look and feel
  - Makes it easier to read

Why you should automate this?
  - Ensures crappy looking code never hits production
  - Reduces review time overall

Combining both find and sed to find and replace words

Example script

find app db spec -type f \( -name '*.rb' -o -name '*.sql' \) -exec sed -i '' -e 's/dollar_value/budget_value/g' {} \;

This script:

• searches in the app, db, and spec directories
• it only looks at file types that are either .rb or .sql files

I've been dealing with large views a lot lately, when looking at individual rows, I find that it dumps to much data on the screen. I found myself using the following pattern a lot.

activity.attributes.slice(*activity.attributes.keys.grep /search_term/

I think it would be cool to instead just go

activity.find_columns(:budget)
