• 🧾 Positional and optional arguments
• 🧠 Type-safe argument parsing (int, bool, string, float)
• 📖 Built-in help message generation
• 🧱 No external dependencies
• 🛠️ Simple, clean API for building CLI tools

How to use

#include <stdio.h>
#include "wimey.h"

int main(int argc, char **argv) {
    // Init Wimey
    if (wimey_init() != WIMEY_OK) {
        ERR("Init failed");
        return 1;
    }
    // Config
    struct wimey_config_t cfg = {
        .name = "Example",
        .description = "Minimal Wimey example",
        .version = "0.1",
        .log_level = LOG_ALL
    };
    wimey_set_config(&cfg);

    // Add inline command
    wimey_add_command((struct wimey_command_t){
        .key = "hello",
        .has_value = true,
        .is_value_required = true,
        .value_name = "name",
        .desc = "Say hello",
        .callback = [](const char *val) {
            INFO("Hello, %s!", val);
        }
    });
    // Parse args
    wimey_parse(argc, argv);
    // Clean up
    wimey_free_all();
    return 0;
}
