matchesPattern()

bool mumufit::stringUtils::matchesPattern	(	const std::string &	text,
		const std::string &	wildcardPattern
	)

Returns true if text matches pattern with wildcards '*' and '?'.

Definition at line 22 of file StringUtils.cpp.

{
    // escape all regex special characters, except '?' and '*'
    std::string mywildcardPattern = wildcardPattern;
    boost::replace_all(mywildcardPattern, "\\", "\\\\");
    boost::replace_all(mywildcardPattern, "^", "\\^");
    boost::replace_all(mywildcardPattern, ".", "\\.");
    boost::replace_all(mywildcardPattern, "$", "\\$");
    boost::replace_all(mywildcardPattern, "|", "\\|");
    boost::replace_all(mywildcardPattern, "(", "\\(");
    boost::replace_all(mywildcardPattern, ")", "\\)");
    boost::replace_all(mywildcardPattern, "[", "\\[");
    boost::replace_all(mywildcardPattern, "]", "\\]");
    boost::replace_all(mywildcardPattern, "+", "\\+");
    boost::replace_all(mywildcardPattern, "/", "\\/");
 
    // Convert chars '*?' to their regex equivalents
    boost::replace_all(mywildcardPattern, "?", ".");
    boost::replace_all(mywildcardPattern, "*", ".*");
 
    // constructing regexp pattern
    mywildcardPattern = "^" + mywildcardPattern + "$";
    std::regex pattern(mywildcardPattern);
 
    // applaying match
    return std::regex_match(text, pattern);
}

scientific()

template<typename T >

std::string mumufit::stringUtils::scientific	(	const T	value,
		int	n = 10
	)

Returns scientific string representing given value of any numeric type.

Definition at line 41 of file StringUtils.h.

{
    std::ostringstream out;
    out << std::scientific << std::setprecision(n) << value;
    return out.str();
}

split()

std::vector< std::string > mumufit::stringUtils::split	(	const std::string &	text,
		const std::string &	delimeter
	)

Split string into vector of string using delimeter.

Returns token vector obtained by splitting string at delimiters.

Definition at line 51 of file StringUtils.cpp.

{
    std::vector<std::string> tokens;
    boost::split(tokens, text, boost::is_any_of(delimiter));
