Ruby: Can I write multi-line string with no concatenation?

🌟 Writing Multi-Line Strings in Ruby with No Concatenation 🌟

Are you tired of messy and hard-to-read code when dealing with multi-line strings in Ruby? Concatenating strings can get tedious and make your code look cluttered. But fear not! In this blog post, we'll explore an easy and elegant solution to write multi-line strings without the need for concatenation. 💪

👀 Identifying the Problem

In the provided code snippet, it's clear that the developer wants to execute a SQL query using the conn.exec method. However, the multiple line breaks and string concatenation make the code difficult to read and maintain. It's no fun having to concatenate long strings with the + operator, especially with a complex query like this one.

🚀 Introducing the Here Document Syntax

Fortunately, Ruby provides a clean and concise way to write multi-line strings using the Here Document syntax. This syntax allows you to define a string literal that spans multiple lines without the need for concatenation.

Instead of concatenating strings, you can simply define the entire query as a single, unbroken string. Let me show you how:

<pre><code>conn.exec <<~SQL SELECT attr1, attr2, attr3, attr4, attr5, attr6, attr7 FROM table1, table2, table3, etc, etc, etc, etc, etc, WHERE etc etc etc etc etc etc etc etc etc etc etc etc etc SQL </code></pre>

With this syntax, you can write your query in a highly readable and structured manner. No more worrying about concatenation or messy code! 🎉

🌈 Additional Benefits

Using the Here Document syntax not only improves the readability of your code, but it also offers a few additional benefits:

1. Preserves indentation: Your multi-line string will maintain the indentation, making it easier to align and format your queries properly.

2. Supports interpolation: You can still use string interpolation within the Here Document. Simply include #{variable_name} within the string, and it will be evaluated accordingly.

🎯 Call to Action: Embrace the Simplicity! 🙌

Now that you've learned this handy technique for writing multi-line strings in Ruby, why not give it a try? Refactor your code snippets and experience the joy of cleaner and more readable code.
