The Sharg parser offers a neat and easy-to-use header-only library for argument parsing in C++. With Sharg, your command line interface can be customized to your specific needs and validated in a single line. Furthermore, the library provides helpful templates and makes even subcommands feel effortless. For more information, details, and a tutorial on how to use our features, please see our online documentation.

If you are working in the field of sequence analysis, we recommend using the SeqAn3 library, which offers a wide range of bioinformatics-related C++ features.

An application with one option parsing an integer from the command line can be written in only 5 lines of code:

#include <sharg/all.hpp> int main(int argc, char ** argv) { int val{}; sharg::parser parser{"Eat-Me-App", argc, argv}; parser.add_subsection("Eating Numbers"); parser.add_option(val, sharg::config{.short_id = 'i', .long_id = "int", .description = "Desc."}); parser.parse(); return 0; }

Done. val is automatically filled with the value provided by -i or --int.

You also have a pretty help page and many more features:

user$ ./Eat-Me-App -h Eat-Me-App ========== OPTIONS Eating Numbers -i, --int (signed 32 bit integer) Desc. Default: 0 Common options -h, --help Prints the help page. -hh, --advanced-help Prints the help page including advanced options. --version Prints the version information. --copyright Prints the copyright/license information. --export-help (std::string) Export the help page information.
