The following combinations are allowed in describing a character class: * **_`x`_:** (where _x_ is not one of the magic characters `^$()%.[]*+-?`) represents the character _x_ itself. * **`.`:** (a dot) represents all characters. * **`%a`:** represents all letters. * **`%c`:** represents all control characters. * **`%d`:** represents all digits. * **`%l`:** represents all lowercase letters. * **`%p`:** represents all punctuation characters. * **`%s`:** represents all space characters. * **`%u`:** represents all uppercase letters. * **`%w`:** represents all alphanumeric characters. * **`%x`:** represents all hexadecimal digits. * **`%z`:** represents the character with representation 0. * **`%`_`x`_:** (where _x_ is any non-alphanumeric character) represents the character _x_. This is the standard way to escape the magic characters. Any punctuation character (even the non magic) can be preceded by a '`%`' when used to represent itself in a pattern. * **`[set]`:** represents the class which is the union of all characters in set. A range of characters can be specified by separating the end characters of the range with a '`-`'. All classes `%`_x_ described above can also be used as components in set. All other characters in set represent themselves. For example, `[%w_]` (or `[_%w]`) represents all alphanumeric characters plus the underscore, `[0-7]` represents the octal digits, and `[0-7%l%-]` represents the octal digits plus the lowercase letters plus the '`-`' character.

The interaction between ranges and classes is not defined. Therefore, patterns like `[%a-z]` or `[a-%%]` have no meaning. * **`[^set]`:** represents the complement of _set_, where _set_ is interpreted as above. For all classes represented by single letters (`%a`, `%c`, etc.), the corresponding uppercase letter represents the complement of the class. For instance, `%S` represents all non-space characters. The definitions of letter, space, and other character groups depend on the current locale. In particular, the class `[a-z]` may not be equivalent to `%l`. _Pattern Item:_ A _pattern item_ can be * a single character class, which matches any single character in the class; * a single character class followed by '`*`', which matches 0 or more repetitions of characters in the class. These repetition items will always match the longest possible sequence; * a single character class followed by '`+`', which matches 1 or more repetitions of characters in the class. These repetition items will always match the longest possible sequence; * a single character class followed by '`-`', which also matches 0 or more repetitions of characters in the class. Unlike '`*`', these repetition items will always match the _shortest_ possible sequence; * a single character class followed by '`?`', which matches 0 or 1 occurrence of a character in the class; * `%n`, for _n_ between 1 and 9; such item matches a substring equal to the _n_-th captured string (see below); * `%bxy`, where _x_ and _y_ are two distinct characters; such item matches strings that start with _x_, end with _y_, and where the _x_ and _y_ are balanced. This means that, if one reads the string from left to right, counting +_1_ for an _x_ and -_1_ for a _y_, the ending _y_ is the first _y_ where the count reaches 0. For instance, the item `%b()` matches expressions with balanced parentheses. _Pattern:_ A _pattern_ is a sequence of pattern items. A '`^`' at the beginning of a pattern anchors the match at the beginning of the subject string. A '`$`' at the end of a pattern anchors the match at the end of the subject string. At other positions, '`^`' and '`$`' have no special meaning and represent themselves. _Captures:_ A pattern can contain sub-patterns enclosed in parentheses; they describe _captures_. When a match succeeds, the substrings of the subject string that match captures are stored (_captured_) for future use. Captures are numbered according to their left parentheses. For instance, in the pattern `"(a*(.)%w(%s*))"`, the part of the string matching `"a*(.)%w(%s*)"` is stored as the first capture (and therefore has number 1); the character matching "`.`" is captured with number 2, and the part matching "`%s*`" has number 3. As a special case, the empty capture `()` captures the current string position (a number). For instance, if we apply the pattern `"()aa()"` on the string `"flaaap"`, there will be two captures: 3 and 5. A pattern cannot contain embedded zeros. Use `%z` instead.
