Quick Answer

Fix syntax completion errors.

Understanding the Issue

Occurs when Ruby code is incomplete (missing "end", parentheses, etc.).

The Problem

This code demonstrates the issue:

Ruby Error 
def calculate
  (1..10).each do |i|
    puts i * 2

The Solution

Here's the corrected code:

Ruby Fixed 
# Correct syntax:
def calculate
  (1..10).each do |i|
    puts i * 2
  end
end

# Tools to prevent:
# 1. Use ruby -c to check syntax
# ruby -c yourfile.rb

# 2. Editor with Ruby linting
# 3. Balanced delimiters:
[1, 2, 3].each { |n| puts n }

# 4. Complete blocks:
begin
  # code
rescue
  # handle
end

Key Takeaways

Ensure all code blocks are properly terminated.
