Function Documentation

std::string camelCaseToSpaces	(	const std::string &	s,
		const std::set< std::string > *	acronyms
	)

Convert a CamelCase string to a string of space-separated words.

Parameters:

acronyms

If non-null, this set of uppercase acronyms will be used as a heuristic to find proper word boundaries.

template<class Itr >

std::string join	(	Itr	it,
		Itr	stop,
		const char *	delim
	)			`[inline]`

Join a sequence of tokens with the given delimiter.

Example:

    const char* toks[] = { "foo", "bar", "baz" };
    string s = join(&toks[0], &toks[0] + 3, "||");

    // s == "foo||bar||baz";

template<class Itr >

std::string lineWrap	(	Itr	itr,
		Itr	stop,
		size_t	linelength,
		const std::string &	pfx = `std::string()`,
		const std::string &	sfx = `std::string()`
	)			`[inline]`

Wrap a sequence of words into a multi-line string, with optional prefix and suffix.

Use stdLineWrap() if you have a single string that should be first split into words on standard whitespace and then line-wrapped.

template<class Itr >

void split	(	const std::string &	in,
		const char *	delim,
		Itr	out
	)			`[inline]`

Split a string into tokens separated by the given delimiters.

Example:

    string s = "/:/foo::bar/:baz///";
    vector<string> tokens;
    split(s, ":/", std::back_inserter(tokens));

    // tokens now contains { "foo", "bar", "baz" };
