Detailed Description

Parses and stores command line program arguments.

Splits command line input into options (key-value pairs) and positional arguments. The options map keys are strings stripped of the leading dash. The arguments vector holds all positional arguments in order.

Constructor & Destructor Documentation

ProgramArgs()

dz::ProgramArgs::ProgramArgs ( int argc, char ** argv )

inline

Constructs the ProgramArgs object by parsing command line arguments.

Parses argc and argv from main() according to rules:

• Arguments starting with '-' are treated as options.
• If an option is followed by a non-option argument, that is its value.
• Otherwise, the option value is an empty string.
• Non-option arguments are collected as positional arguments.

Parameters

argc	Number of command line arguments.
argv	Array of C-string arguments.

Member Data Documentation

arguments

std::vector<std::string> dz::ProgramArgs::arguments

Vector of positional arguments parsed from command line.

Arguments that do not begin with a dash are stored here, preserving order.

options

std::unordered_map<std::string, std::string> dz::ProgramArgs::options

Map storing options parsed from command line arguments.

Keys are option names (without leading dash). Values are option values, or empty string if no value was provided.
