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>

.
