CLI11 provides all the features you expect in a powerful command line parser, with a beautiful, minimal syntax and no dependencies beyond C++11. itk-wasm enhances CLI11 with a itk::wasm::Pipeline wrapper to support efficient execution in multiple Wasm contexts, scientific data structures, and lovely colorized help output 🥰.
CLI11 is making all the other options libraries look bad, does anyone have a comparison from experience?
6 projects | /r/cpp | 25 Aug 2022

Does anyone have feedback on the possible problems with CLI11 and comparisons to any other thing available in the wild not limited to the choices I tried before? Looks like a very well-thought out library according to its documentation: https://cliutils.github.io/CLI11/book/

I'd recommend to use CLI11. I was baffled by how much it can do.

I use https://github.com/jarro2783/cxxopts.git or https://github.com/CLIUtils/CLI11, or if boost is involved anyway, boost.program_options.

Maybe https://github.com/CLIUtils/CLI11? I really like this one and it looks like it supports TOML
Why no standard library support for command line parsing?
2 projects | /r/cpp | 27 Jan 2021

I found https://github.com/jarro2783/cxxopts to be useful and https://github.com/CLIUtils/CLI11 to be really helpful if you need an non-trivial interface.

TCLAP is my personal favorite.
Why no standard library support for command line parsing?
2 projects | /r/cpp | 27 Jan 2021

I use TCLAP (Templatized C++ Command Line Parser). I found this library 6 years ago, and I added it to all my projects. It's based on STL and works on every platform. https://github.com/mirror/tclap/
