A simple and small c++ argument parser.
Takes argc and argv as arguments.
argparser::argparser(int argc, char** argv);enum arg_type{
A_INT = 0,
A_FLOAT = 1,
A_DOUBLE = 2,
A_STRING = 3,
A_CHAR = 4,
A_BOOL = 5,
A_NONE = 6
};Takes a_name as long name, alt_name as short name, desc as option description, is_parsed reference to where to store a boolean true if the argument has been passed though cmd, is_required is true if option is required.
void add_option(const char* a_name, const char* alt_name, bool *is_parsed,
const char* desc, bool is_required);Argument type for the type of value parsed. Argument ref reference to where to store the value.
void add_option(const char* a_name, const char* alt_name, bool *is_parsed,
arg_type type, void* ref, const char* desc, bool is_required);make
bool age_parsed = false;
bool hello_parsed = false;
int m_age;
argparser m_argparse(argc, argv);
m_argparse.set_header_info("Simple program v0.0.1.");
