Description

Implementation of widely used helper functions.

The helpers implemented here are typically accessed by including util.hpp, so the reason of pushing down the implementation into a separate translation unit (this one here) is to avoid more heavyweight includes (e.g. boost).

Definition in file util.cpp.

Functions
ChPredicate	operator! (ChPredicate p)
ChPredicate	isValid (is_alnum() or is_any_of("-_.+$()@"))
	characters to be retained
ChPredicate	isPunct (is_space() or is_any_of(",;:#*~´`?\\=/&%![]{}<>"))
	punctuation to be replaced by '_'
std::string	sanitise (string const &org)
	produce an identifier based on the given string.
string	trim (string const &org)
	remove leading and trailing whitespace
bool	boolVal (string const &)
	interpret text representation of a boolean value.
bool	isYes (string const &) noexcept
	check the given text if it can be interpreted as affirmative answer (bool true).
bool	isNo (string const &) noexcept
	check if the given text is empty or can be interpreted as rejection (bool false)-
