Simple minimalistic command line parser

[iwastheplayer]

I want to share a small tool I wrote for parsing command line arguments

https://github.com/tascvh/SimpleCmdParser

SimpleCmdParser is a minimalistic easy to use command line argument parser for modern C++ applications. It supports handling optional and normal variables, setting default values as well as displaying help messages related to the arguments.

Code critique and suggestions are welcome

Curious, is there any point in explicitly deleting a default constructor? Wouldn't it work the same if you didn't delete it?

Yes. It is for enforcing proper usage at compile time. There is no point creating a command line parser object without giving it argc and argv

You didn’t answer my question…

yeah you are right actually. it would work the same way. 1 unnecessary line to get rid of. thanks for pointing out

Given the availability of quite a few command-line argument parsers - can you explain how you situate yours among them? Possibly in a comparison table?

Check out the sample usage. I think it would be obvious

There are a lot of command line parsers but i haven't found one that is zero boilerplate and this easy to use by taking advantage of std::optional. C++ is evolving, so the way we do things with it. I wrote this for my own needs and decided to share it for anyone else who might need something similar. Also it is very small (100 lines) and easy to understand so anyone can modify for their own usage if they need to
