## Lua Patterns
The following is taken from the
[Lua 5.1 Reference Manual](http://www.lua.org/manual/5.1/manual.html#5.4.1).
_Character Class:_
A character class is used to represent a set of characters. 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.
<br /><br />
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.
