stb-style c99 library for handling flags in CLI applications.
See example.c
- Include the library in your header files
#include "redflag.h"- In only one source file include the library but declare REDFLAG_IMPLEMENTATION first.
#define REDFLAG_IMPLEMENTATION
#include "redflag.h"- Create and init a context instance
rf_context_t ctx;
rf_init_context(&ctx);- Add options/flags
rf_flag_bool(ctx*, name, desc, default_value);
rf_flag_int(ctx*, name, desc, default_value);
rf_flag_float(ctx*, name, desc, default_value);
rf_flag_str(ctx*, name, desc, default_value);
// All of these functions return a rf_flag_t pointer that is owned by the context- After you have declared all your options/flags you can parse them
rf_parse_flags(&ctx, argc, argv);- After you have parsed the options/flags you can check their values
rf_flag_t* flag = rf_flag_str(&ctx, "test", "this is a test value", "default value");
rf_parse_flags(&ctx, argc, argv);
const char *value = flag->value.as_str;
printf("Value: %s\n", value);- Remember to free the allocated memory
rf_free_context(&ctx);
