Useful code snippets with C++ boost

Is Punctuation

It’s very straight forward to use boost.regex as a solution. We can match the input string with a regex like

if (boost::regex_match(",", boost::regex("[[:punct:]]"))) { std::cout << "is punctuation." << std::endl; }

If the ICU is also in our consideration, code should be modified as

if (boost::u32regex_match("!", boost::make_u32regex("[[:P*:]]"))) { std::cout << "is unicode punctuation." << std::endl; }

Argument Parser

Like optparse.OptionParser in Python, boost also provides a very nice command line arguments parser, in <boost/program_options.hpp>.

Now, it’s argparse.ArgumentParser.
