string_util Namespace Reference

Detailed Description

some common string processing functions, for std::string

Functions

string makeLower (const std::string &s) ATTR_must_check

returns lower case version of s

string makeUpper (const std::string &s) ATTR_must_check

returns upper case version of s

string removePrefix (const std::string &str, const std::string &pre) ATTR_must_check

returns str with pre removed - if pre is not fully matched, str is returned unchanged

string tildeExpansion (const std::string &str) ATTR_must_check

replaces ~USER prefix with specified user's home directory, or ~ prefix with current HOME environment setting; returns str if no valid expansion is found

string trim (const std::string &str) ATTR_must_check

removes whitespace (as defined by isspace()) from the beginning and end of str, and returns the result

bool parseArgs (const std::string &input, std::vector< std::string > &args, std::vector< unsigned int > &offsets)

parses the input string into an arg list, with corresponding offsets of each arg in the original input
