"""Support for regular expressions (RE).
This module provides regular expression matching operations similar to
those found in Perl. It's 8-bit clean: the strings being processed may
contain both null bytes and characters whose high bit is set. Regular
expression pattern strings may not contain null bytes, but can specify
the null byte using the
\\
number notation. Characters with the high
bit set may be included.
Regular expressions can contain both special and ordinary
characters. Most ordinary characters, like "A", "a", or "0", are the
simplest regular expressions; they simply match themselves. You can
concatenate ordinary characters, so last matches the string 'last'.
The special characters are:
"." Matches any character except a newline.
"^" Matches the start of the string.
"$" Matches the end of the string.
"*" Matches 0 or more (greedy) repetitions of the preceding RE.
Greedy means that it will match as many repetitions as possible.
"+" Matches 1 or more (greedy) repetitions of the preceding RE.
"?" Matches 0 or 1 (greedy) of the preceding RE.
*?,+?,?? Non-greedy versions of the previous three special characters.
{m,n} Matches from m to n repetitions of the preceding RE.
{m,n}? Non-greedy version of the above.
"
\\
" Either escapes special characters or signals a special sequence.
[] Indicates a set of characters.
A "^" as the first character indicates a complementing set.
"|" A|B, creates an RE that will match either A or B.
(...) Matches the RE inside the parentheses.
The contents can be retrieved or matched later in the string.
(?iLmsx) Set the I, L, M, S, or X flag for the RE.
(?:...) Non-grouping version of regular parentheses.
(?P<name>...) The substring matched by the group is accessible by name.
(?P=name) Matches the text matched earlier by the group named name.
(?#...) A comment; ignored.
(?=...) Matches if ... matches next, but doesn't consume the string.
(?!...) Matches if ... doesn't match next.
The special sequences consist of "
\\
" and a character from the list
below. If the ordinary character is not on the list, then the
resulting RE will match the second character.
\\
number Matches the contents of the group of the same number.
\\
A Matches only at the start of the string.
\\
Z Matches only at the end of the string.
\\
b Matches the empty string, but only at the start or end of a word.
\\
B Matches the empty string, but not at the start or end of a word.
\\
d Matches any decimal digit; equivalent to the set [0-9].
\\
D Matches any non-digit character; equivalent to the set [^0-9].
\\
s Matches any whitespace character; equivalent to [
\\
t
\\
n
\\
r
\\
f
\\
v].
\\
S Matches any non-whitespace character; equiv. to [^
\\
t
\\
n
\\
r
\\
f
\\
v].
\\
w Matches any alphanumeric character; equivalent to [a-zA-Z0-9_].
With LOCALE, it will match the set [0-9_] plus characters defined
as letters for the current locale.
\\
W Matches the complement of
\\
w.
\\\\
Matches a literal backslash.
This module exports the following functions:
match Match a regular expression pattern to the beginning of a string.
search Search a string for the presence of a pattern.
sub Substitute occurrences of a pattern found in a string.
subn Same as sub, but also return the number of substitutions made.
split Split a string by the occurrences of a pattern.
findall Find all occurrences of a pattern in a string.
compile Compile a pattern into a RegexObject.
purge Clear the regular expression cache.
template Compile a template pattern, returning a pattern object.
escape Backslash all non-alphanumerics in a string.
Some of the functions in this module takes flags as optional parameters:
I IGNORECASE Perform case-insensitive matching.
L LOCALE Make
\
w,
\
W,
\b
,
\
B, dependent on the current locale.
M MULTILINE "^" matches the beginning of lines as well as the string.
"$" matches the end of lines as well as the string.
S DOTALL "." matches any character at all, including the newline.
X VERBOSE Ignore whitespace and comments for nicer looking RE's.
U UNICODE Use unicode locale.
This module also defines an exception 'error'.
