What are some examples of using Ruby for synchronous programming?

Can you give me some examples of using Ruby for synchronous programming?

Sure! In Ruby, synchronous programming means that tasks are executed one after another. For example, reading a file and processing its content sequentially.

What about using threads in Ruby? Can that be synchronous?

Threads in Ruby can be used for concurrent programming, but they can also be managed to run synchronously by ensuring that one thread completes before another starts.

Can you show me a code snippet for synchronous file reading?

Absolutely! Here's a simple example:

file = File.open('example.txt', 'r')
content = file.read
file.close
puts content

This reads the file synchronously.

Are there any libraries that help with synchronous programming in Ruby?

Yes, libraries like 'EventMachine' can help manage synchronous tasks, although they are often used for asynchronous programming. You can also use standard Ruby methods for synchronous operations.
