Argparse is a small library to parse command line arguments.
The example generates a cli which has the following form:
Usage: custom-flag [options]
Options:
-h, --help Display help message.
-V, --version Display the version.
-c, --custom-flag A custom flag
#include "argparse/argparse.h"
void custom_flag_set(context_t *context) {
//custom flag was set.
bool *flag_set = context->data;
*flag_set = true;
}
int main(int argc, const char **argv) {
command_t command;
command_init(&command, "custom-flag", "0.0.0");
//short name, long-name, description, callback
//-> -c, --custom-flag, A custom flag
command_flag(&command, 'c', "custom-flag", "A custom flag", custom_flag_set);
bool flag_set = false; //this will be passed to the context
command_parse(&command, &flag_set, argc, argv);
command_destroy(&command);
}
