This is probably better asked on the software engineering stackexchange — Gabe Sechan 40 secs ago

- Stack Overflow is for professional and enthusiast programmers, or anyone who writes code because they love it — Cooper 28 secs ago

This site has requirements for a reason, which is to make sure that sufficient details are here for future site users. The purpose of this site is not to help individual people with immediate problems, but to build a knowledge base for programmers. Your post is missing details, which I have asked you to provide properly. The fact it's your homework is irrelevant, except it brings up How to Ask (And Answer) Homework Questions? as well as the links I provided earlier. I'd also suggest you check your attitude - you're asking us to help you. — Ken White 22 secs ago

@IInspectable: There's nothing vague about the title. I agree that the body of the question sounds as though it might invite open-ended discussions, but it actually elicited a couple specific, highly-voted answers that appear to have provided value to other programmers before it was closed. And, of course, it has been re-opened. — Adrian McCarthy 58 secs ago

Any reason to not prepend a "2", and do 2 ctrl + o ? (As for "not a programming problem", my understanding has been that SO is open to questions about "software tools commonly used by programmers"; so vi/vim would qualify, and indeed have their own tags. Having said that, I sometimes wonder why vi/vim/nvim questions end up here rather than vi.stackexchange.com — m_mlvx just now

As a software engineer for years, I don't think it's a good OOP practice / interface for HttpParams. After all you assume set does also works on an existing object, why shouldn't it? Saying it's intended to be immutable doesn't give me a good reason why it should be immutable. — Melroy van den Berg 5 secs ago

Also, some newer C programmers seem to form the misunderstanding that typedef is part of the syntax for defining structure types. It is not. Typedef declarations can be combined with structure type definitions, but such a combined declaration is still doing two logically distinct things -- defining a structure type and declaring an alias for that type. — John Bollinger 37 secs ago

Stack Overflow doesn't deal in recommendations because what makes for a good library is a moving target. Give Software Recommendations a shot at this question. — user4581301 13 secs ago

Stack Overflow's not the right place to ask for software recommendations. Software Recommendations is, but read the asking questions section of their Help Center so you can tune your question to fit their rules. — user4581301 17 secs ago
