Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

-
Command line interface library
The most feature-rich C++ CLI library is CLI11. Other popular choices include Boost.ProgramOptions, argparse, cxxopts and others.
-
Recommended Argument Parsing Library?
I've used cxxopts and can't complain. It's available on both Conan and vcpkg.
- Confusion about libraries and project structure
-
Quick question about int main(int argc, char **argv)
For streamlined command line option parsing check out a library like cxxopts or similar. There are plenty out there.
-
How do you make a command line argument of this format: ./executableName "input = inputFileName; output = outputFileName"
Have a look at cxxopts which is similar to the python getopt functions, It's header only so easy to use (just dump the header in your project). There is also boost::program_options but this requires boost which is big.
-
CLI11 is making all the other options libraries look bad, does anyone have a comparison from experience?
I use CLI11 for more complex things, https://github.com/jarro2783/cxxopts for simpler interfaces, and boost.program_options if I have to and have boost anyways as dependency.
-
Is there a macro for the output directory on msvc?
Let the user pass the path/filename as an input argument to the program. Your main() function takes arguments from the console, so you could invoke your program as .\my_program --err_log "\path\to\my_errors.log". Of course this again only works if executed from the console - you can however create a desktop shortcut that invokes your program with this argument and you can also configure your IDE to pass this argument when running your program. To make parsing input arguments easier, use a library such as cxxopts
-
Command Line Argument That Can Take Multiple Parameters
You probably want the header only library cxxopts.
-
How to create my own command using cpp?
To make parsing command line options easier I can recommend the cxxopts library.
-
Dumb question: what data structure do you use to represent a collection of config values passed in via command line arguments/
I have previously used this: https://github.com/jarro2783/cxxopts

What are some alternatives?
CLI11 - CLI11 is a command line parser for C++11 and beyond that provides a rich feature set with a simple and intuitive interface.
text - A spicy text library for C++ that has the explicit goal of enabling the entire ecosystem to share in proper forward progress towards a bright Unicode future.
Boost.Program_options - Boost.org program_options module
args - A simple header-only C++ argument parser library. Supposed to be flexible and powerful, and attempts to be compatible with the functionality of the Python standard argparse library (though not necessarily the API).
gflags - The gflags package contains a C++ library that implements commandline flags processing. It includes built-in support for standard types such as string and the ability to define flags in the source file in which they are used. Online documentation available at:
clipp - easy to use, powerful & expressive command line argument parsing for modern C++ / single header / usage & doc generation
argumentum - C++ command line parsing library
tclap - Templatized C++ Command Line Parser mirror
conan - Conan - The open-source C and C++ package manager
docopt.cpp - C++11 port of docopt
