A helper that checks the length of a string and which adds three dots if that string exceeds a given length.

text_length_helper.rb

module TextLengthHelper
  def text_length(string, max_length)
    return string if string.length <= max_length
    string[0..(max_length - 1)] + "..."
  end
end

text_length_helper_spec.rb

require_relative 'text_length_helper'

describe TextLengthHelper do
  include TextLengthHelper
  
  full_text = "Lorem ipsum dolor sit amet, consectetur adipiscing elit."
  short_text = "Lorem ipsum dolor sit amet, consectetur adipiscing..."

  it "should stay the same when a text is shorter than 100" do
    text_length(full_text, 100).should eq full_text
  end

  it "should return a text with dots given a string longer than 50" do
    text_length(full_text, 50).should eq short_text
  end
  
  it "should not have dots when given an empty string" do
    text_length("", 50).should eq ""
  end
  
end

nog wat compacter :)

def text_length(string, max_length)
  return string if string.length <= max_length
  string[0..(max_length - 1)] + "..."
end

Tnx, Ik pas hem aan!
