std::string	regroup (const std::string &regex)
	Regroup: convert a string regex to a regex with group captures only for the outermost (top-level) choices. All outermost (top-level) choices `X1`, `X2`, ... `Xn` in a regex `X1\|X2\|...\|Xn` are regrouped such that `X1\|X2\|...\|Xn` => `(X1)\|(X2)\|...\|(Xn)`. Innermost (nested) group captures `(Y)` are converted to non-captured `(Y)` => `(?:Y)`. All existing non-capturing groups are retained. For example, `a\|b(c)\|(?:d)` => `(a)\|(b(?:c))\|((?:d))`.

int	isword (int c)
	Check word character. More...

template<typename S1 , typename S2 >

	Check if sets `s1` and `s2` are disjoint. More...

template<typename T , typename S >

unicode_t	utf8 (const char *s)
	Convert UTF-8 to UCS, returns 0xFFFD for invalid UTF-8 except for MUTF-8 U+0000 and 0xD800-0xDFFF surrogate halves (use WITH_UTF8_UNRESTRICTED to remove this limit to support lossless UTF-8 encoding up to 6 bytes). More...

template<typename S1 , typename S2 >

bool reflex::is_disjoint	(	const S1 &	s1,
		const S2 &	s2
	)

Check if sets s1 and s2 are disjoint.

Returns: true or false

template<typename T , typename S >

bool reflex::is_in_set	(	const T &	x,
		const S &	s
	)

inline

Check if value x is in set s.

Returns: true or false

template<typename S1 , typename S2 >

bool reflex::is_subset	(	const S1 &	s1,
		const S2 &	s2
	)

Check if set s1 is a subset of set s2.

Returns: true or false

int reflex::isword ( int c )

inline

Check word character.

Returns: nonzero if argument c is in [A-Za-z0-9_], zero otherwise.

Parameters

c	Character to check

std::string reflex::regroup ( const std::string & regex )

Regroup: convert a string regex to a regex with group captures only for the outermost (top-level) choices. All outermost (top-level) choices X1, X2, ... Xn in a regex X1|X2|...|Xn are regrouped such that X1|X2|...|Xn => (X1)|(X2)|...|(Xn). Innermost (nested) group captures (Y) are converted to non-captured (Y) => (?:Y). All existing non-capturing groups are retained. For example, a|b(c)|(?:d) => (a)|(b(?:c))|((?:d)).

template<typename S1 , typename S2 >

void reflex::set_delete	(	S1 &	s1,
		const S2 &	s2
	)

Delete elements of set s2 from set s1.

template<typename S1 , typename S2 >

void reflex::set_insert	(	S1 &	s1,
		const S2 &	s2
	)

inline

Insert set s2 into set s1.

std::string reflex::utf8	(	unicode_t	a,
		unicode_t	b,
		bool	strict = `true`,
		const char *	esc = `NULL`
	)

Convert a UCS range [a,b] to a UTF-8 regex pattern.

Returns: regex string to match the UCS range encoded in UTF-8.

Parameters

a	lower bound of UCS range
b	upper bound of UCS range
strict	returned regex is strict UTF-8 (true) or permissive and lean UTF-8 (false)
esc	escape char(s), 0-3 chars limit, one backslash "\\" is the default

size_t reflex::utf8	(	unicode_t	c,
		char *	s
	)

inline

Convert UCS to UTF-8.

Returns: length (in bytes) of UTF-8 character sequence stored in s.

Parameters

c	UCS character
s	points to the buffer to populate with UTF-8 (1 to 6 bytes) not \0-terminated

unicode_t reflex::utf8 ( const char * s )

inline

Convert UTF-8 to UCS, returns 0xFFFD for invalid UTF-8 except for MUTF-8 U+0000 and 0xD800-0xDFFF surrogate halves (use WITH_UTF8_UNRESTRICTED to remove this limit to support lossless UTF-8 encoding up to 6 bytes).

Returns: UCS character.

Parameters

s	points to the buffer with UTF-8 (1 to 6 bytes)
