Use synvert without writing any code at all

On March 2nd, 2023, I read a tip in Ruby Weekly.

!value.nil? is a lot faster than value != nil

It’s nearly 5 times faster, so I want to update my code base accordingly.

I open the Synvert app, copy the code from the tip and paste them into inputs and expected outputs.

Then I click the “Generate Snippet” button, and Synvert generates a snippet for me.

After reviewing the snippet, I click the “Search” button, and Synvert finds all occurrences of value != nil in my code base.

I can selectively apply the changes or click “Replace All” button to apply them all at once.

I can run git diff to view all changes in my code base.
