Is Your Enhancement Request Related to an Issue?

At present, we load all file contents into memory and do a singular RegExp match and replace operation. Doing it this way is not optimal (not too impactful, but we strive to ship good software c;);

• Will require more memory
• Will impact runtime performance

Describe the Solution You'd Like

File streaming.

Instead of loading the file contents into memory, we can just;

1. stream each line of the file into memory
2. format the line with the same RegExp
3. stream the formatted line into a generated file in a generated temp directory
4. then replace the original file with the formatted file

[!NOTE] I have already tried to implement this, albeit unsuccessfully. You can find my unsuccessful code highlighted here.
