ArgParser

ArgParser is a simple, single header-only C++17 library to parse command like input. Similar in functionality to tools like cargo, the Rust package manager. It started as a testing project and after some development I thought that someone could use this as well.

This library was tested on Windows (MSCV) and GNU/Linux (GCC, Clang), with additional checking on GNU/Linux with Valgrind

Examples

Example 1:

#include "arg_parser.hpp"

int main(int argc, char* argv[])
{
    psap::ArgParser parser{
        psap::ParserConf{"project_name", 4, true, true, psap::ValueStyle::Both, psap::UnknownOptionPolicy::ReportRemove}};

    auto HELP_ACTION = 
        [](const psap::ArgParser &parser, const psap::Command &cmd)
        {
            parser(parser[0]); // Print info text of remaining args
        }

    parser.command("help", "h")
        .help("Shows help.")
        .action(HELP_ACTION);

    //More commands to come

    parser.parse(argv, argc);
}

Output:

Usage: project_name [Command] [Options]

Commands:
    help, h    Shows help.

See 'project_name help <command>' for more information on a specific command.

Example 2:

    psap::ArgParser parser{
        psap::ParserConf{"project_name", 4, true, true, psap::ValueStyle::Both, psap::UnknownOptionPolicy::ReportRemove}};

    auto RUN_ACTION = 
        [](const psap::ArgParser &parser, const psap::Command &cmd)
        {
            //Run action...
        }

    parser.command("run", "r")
        .help("Runs something.")
        .option(psap::make_value("--target", "-t", "Select a Target."))
        .option(psap::make_flag("--debug", "-d", "Runs in debug."))
        .action(RUN_ACTION);

    //More commands to come

    parser.parse(argv, argc);
