Hi Fellow CodinGamers!
I like to use good, decriptive names in my source files like ‘findEmergencyMissionsAndAssignOperatives’ for a method.
This convention helps to understand my sources better, maintain them, find reusable parts more easily after months or even after years.
CodinGame has a 50 KiloByte upload limit currently, which forces us to limit ourselves for having an easily maintainable code, especially for long contests.
So I choose to shrink my source code with a simple tool to have it within the limit, but keep the line numbers for easy trackback of exceptions in the original source code.
My source code became about 50% smaller with it.
The tool:

Feel free to use, share, modify it!
Notes:
- I take no responsibility for the improper usage of the tool.
- Use a source control system to keep your files safe, and protect them from unwanted changes.
- I give no support for the tool. Anyway it speeks for itself.
- I think the tool can be easily ported to other languages, if someone wants it.
Happy Coding!
