What is libdocopt-dev
libdocopt-dev is:
With docopt, the option parser is generated based on the program’s docstring. docopt parses the usage pattern (“Usage: …”) and option descriptions (lines starting with dash “-”) and ensures that the program invocation matches the usage pattern. It parses options, arguments and commands based on that. The basic idea is that a good help message has all necessary information in it to make a parser.
This is a port of the docopt Python module to C++ with a focus on maintaining full feature parity (and code structure) as the original. The differences from the Python port are:
The addition of a docopt_parse function, which does not terminate the program on error a docopt::value type to hold the various value types that can be parsed.
Because C++ is statically-typed and Python is not, some changes were made to the interfaces of the internal parse tree types.
Because std::regex does not have an equivalent to Python’s regex.split, some of the regex’s had to be restructured and additional loops used.
