regexp

The RegExp class has these methods:

Create a new RegExp object. Compile pattern[] with attributes[] into an internal form for fast execution. Throws a RegExpError if there are any compilation errors.

char[][] split(char[] string)

Split string[] into an array of strings, using the regular expression as the separator. Returns array of slices in string[].

int search(char[] string)

Search string[] for match with regular expression.

Returns	Description
>=0	index of match
-1	no match

Search string[] for match.

Attribute	Returns
global	same as call to exec(string)
not global	array of all matches

Search string[] for next match. Returns array of slices into string[] representing matches.

int test(char[] string)

Search string[] for next match.

Returns	Description
0	no match
!=0	match

Find regular expression matches in string[]. Replace those matches with a new string composed of format[] merged with the result of the matches.

Attribute	Action
global	replace all matches
not global	replace first match

char[] replace(char[] format)

After a match is found with test(), this function will take the match results and, using the format[] string, generate and return a new string. The format commands are:

Format	Description
$$	insert $
$&	insert the matched substring
$`	insert the string that precedes the match
$'	insert the string that following the match
$n	replace with the nth parenthesized match, n is 1..9
$nn	replace with the nnth parenthesized match, nn is 01..99
$	insert $

Like replace(char[] format), but uses old style formatting:

Format	Description
&	replace with the match
\n	replace with the nth parenthesized match, n is 1..9
\c	replace with char c.

stdint

The exact aliases are types of exactly the specified number of bits. The at least aliases are at least the specified number of bits large, and can be larger. The fast aliases are the fastest integral type supported by the processor that is at least as wide as the specified number of bits.
