Notable features

Compile time evaluated model

The model to define the command line parser is defined in templates. All definition and verification of the model is evaluated during the compilation.

Up to date library

The library is written in C++20 with its new language features like concepts, ranges, views... which make the library easier to use and maintain.

Flexible

The model is easy to update or to personnalize by the user himself.

Error analysis and validators

Several error types is catch and returned for a better analysis or the arguments. Validators over input and argument values can be set up to check parameter during parsing.

Moreover, the library doesn't use exception but expected class in return instead.

Tested using Google Test

A complete test program is available in "tests" to check the parser. As I'm writing this doc, all of the 50 tests passed successfully !

UTF-8 text

The library works with UTF-8 text. So if you want to use emoji or non latin alphabet in long or short name, you can !
