Functions
bool	utils::isnewline (const char c)
bool	utils::portable_isspace (const char c)
bool	utils::notspace (const char c)
std::vector< std::string >	utils::split (std::string const &val, const char c, const int flags)
	Splits a (comma-)separated string into a vector of pieces. More...
std::vector< std::string >	utils::square_parenthetical_split (std::string const &val, const char separator= ',', std::string const &left="([", std::string const &right=")]", const int flags=REMOVE_EMPTY|STRIP_SPACES)
	Similar to parenthetical_split, but also expands embedded square brackets. More...
std::map< std::string, std::string >	utils::map_split (std::string const &val, char major= ',', char minor= ':', int flags=REMOVE_EMPTY|STRIP_SPACES, std::string const &default_value="")
	Splits a string based on two separators into a map. More...
std::vector< std::string >	utils::parenthetical_split (std::string const &val, const char separator=0, std::string const &left="(", std::string const &right=")", const int flags=REMOVE_EMPTY|STRIP_SPACES)
	Splits a string based either on a separator where text within parenthesis is protected from splitting (Note that one can use the same character for both the left and right parenthesis. More...
int	utils::apply_modifier (const int number, const std::string &amount, const int minimum)
std::string	utils::escape (const std::string &str, const char *special_chars)
	Prepends a configurable set of characters with a backslash. More...
static void	utils::si_string_impl_stream_write (std::stringstream &ss, double input)
static bool	utils::is_username_char (char c)
static bool	utils::is_wildcard_char (char c)
static bool	utils::is_word_boundary (char c)
std::string	utils::indent (const std::string &string, size_t indent_size=4)
	Indent a block of text. More...
std::vector< std::string >	utils::quoted_split (std::string const &val, char c= ',', int flags=REMOVE_EMPTY|STRIP_SPACES, char quote= '\\')
	This function is identical to split(), except it does not split when it otherwise would if the previous character was identical to the parameter 'quote'. More...
std::pair< int, int >	utils::parse_range (std::string const &str)
std::vector< std::pair< int, int > >	utils::parse_ranges (std::string const &str)
std::string	utils::replace (std::string str, const std::string &src, const std::string &dst)
	Replace all instances of src in str with dst. More...
std::string &	utils::strip (std::string &str)
	Remove whitespace from the front and back of the string 'str'. More...
std::string &	utils::strip_end (std::string &str)
	Remove whitespace from the back of the string 'str'. More...
std::string	utils::unescape (const std::string &str)
	Remove all escape characters (backslash) More...
std::string	utils::urlencode (const std::string &str)
	Percent-escape characters in a UTF-8 string intended to be part of a URL. More...
bool	utils::string_bool (const std::string &str, bool def=false)
	Convert no, false, off, 0, 0.0 to false, empty to def, and others to true. More...
std::string	utils::signed_value (int val)
	Convert into a signed value (using the Unicode "−" and +0 convention. More...
std::string	utils::half_signed_value (int val)
	Sign with Unicode "−" if negative. More...
std::string	utils::si_string (double input, bool base2, std::string unit)
	Convert into a string with an SI-postfix. More...
bool	utils::isvalid_username (const std::string &login)
	Check if the username contains only valid characters. More...
bool	utils::isvalid_wildcard (const std::string &login)
	Check if the username pattern contains only valid characters. More...
bool	utils::word_completion (std::string &text, std::vector< std::string > &wordlist)
	Try to complete the last word of 'text' with the 'wordlist'. More...
bool	utils::word_match (const std::string &message, const std::string &word)
	Check if a message contains a word. More...
bool	utils::wildcard_string_match (const std::string &str, const std::string &match)
	Match using '*' as any number of characters (including none), and '?' as any one character. More...
void	utils::ellipsis_truncate (std::string &str, const size_t size)
	Truncates a string to a given utf-8 character count and then appends an ellipsis. More...
