Function Documentation

◆ match() [1/2]

bool reg::match	(	std::string_view	str,
		Match &	match,
		const Ex &	re
	)

Matches a given string str for a match against regular expression re.

Returns true iff a match was found for the whole string. Any capture groups are returned via the match object.

◆ match() [2/2]

bool reg::match	(	std::string_view	str,
		const Ex &	re
	)

Matches a given string str for a match against regular expression re.

Returns true iff a match was found for the whole string.

◆ search() [1/2]

bool reg::search	(	std::string_view	str,
		Match &	match,
		const Ex &	re,
		size_t	pos = `0`
	)

Search in a given string str starting at position pos for a match against regular expression re.

Returns true iff a match was found. Details of what part of the string has matched is returned via the match object.

An example to show how to match all identifiers in a string.

static reg::Ex re(R"(\a\w*)");
std::string = u8"void(Func是<B_C::Códe42>(42));";
while (reg::search(str,match,re,pos))
{
  std::cout << match.str() << std::endl;
  pos=match.position()+match.length();
}

produces:

void
Func是
B_C
Códe42
