Block comments come in handy when you need to write longer explanations or instructions within your code. It is often used when you want to temporarily disable a section of your code without removing it. In this blog post, we will look at how to create block comments in Ruby.
Using the =begin and =end Syntax
In Ruby, you can create a block comment by using the =begin and =end syntax. These special markers indicate the start and end of a block comment, respectively. Anything between these markers will be treated as a comment and ignored by the Ruby interpreter.
=begin This is a block comment. You can write multiple lines of text here. The Ruby interpreter will ignore everything between =begin and =end. =end puts "Hello, World!"
Note that =begin and =end must be at the beginning of a line and should not be indented. Additionally, there should be no whitespace or other characters between the equal sign (=) and the keywords “begin” and “end.”
Using Inline Comments
If you only need to comment out a few lines of code, you can use the inline comment syntax by inserting the hash symbol (#) at the beginning of each line you want to comment out. This is a quicker way to create block comments in Ruby, especially for smaller sections of code.# This is an inline comment # You can also create block comments by using # inline comments for each line puts "Hello, World!"
While inline comments are easier to write, they might not look as neat as using the =begin and =end syntax for longer sections of code.
In this blog post, we have learned how to create block comments in Ruby using the =begin and =end syntax, as well as using inline comments. Remember to keep your comments concise and informative to help other developers understand your code better.
