Argparse

A Python argparse inspired argument parser written for C. This is just meant to be a fun exercise in C, and does not seek to achieve feature parity with the Python implementation.

Usage

Note

This project is under active development and does not even have base functionality yet! This section has been provided to show what it might look like.

int main(int argc, char* argv[]) {
    // parsed args to be used throughout program
    typedef struct Arguments {
        char* path;
        int lines;
    } Arguments;
    // set default values first
    Arguments args = {.lines = 10};
    ArgParser parser = {"Description of your program"};
    Arg* options = {
      {"filename", &args.path, .help="The name of the file to open"},
      {"--lines", &args.lines, .transform=&toInt, .help="The max number of lines to read"},
      {0}};
    // parse into Arguments struct
    parse_args(parser, options, argc, argv);

    printf("Opening file %s and read %d lines..\n",args.path, args.lines);
    return 0;
