This module implements regular expression operations. Regular expression syntax supported is a subset of CPython re module (and actually is a subset of POSIX extended regular expressions).
Supported operators are:
.
Match any character. []
Match set of characters. Individual characters and ranges are supported.
^
$
?
*
+
??
*?
+?
Counted repetitions ({m,n})
, more advanced assertions, named groups, etc. are not supported.
Compile regular expression, return regex object
.
Match regex against string
. Match always happens from starting position in a string.
Search regex in a string. Unlike match, this will search string for first position which matches regex (which still may be 0 if regex is anchored).
Flag value, display debug information about compiled expression.
Compiled regular expression. Instances of this class are created using ure.compile()
.
Match objects as returned by match()
and search()
methods.
Only numeric groups are supported.
