When imported as a module, there are two functions, with their own strings: convert(s, syntax=None) -- convert a regex regular expression to re syntax quote(s) -- return a quoted string literal When used as a script, read a Python string literal (or any other expression evaluating to a string) from stdin, and write the translated expression to stdout as a string literal. Unless stdout is a tty, no trailing \n is written to stdout. This is done so that it can be used with Emacs C-U M-| (shell-command-on-region with argument which filters the region through the shell command). No attempt has been made at coding for performance.

The first argument is the regular expression, as a string object, just like it would be passed to regex.compile(). (I.e., pass the actual string object -- string quotes must already have been removed and the standard escape processing has already been done, e.g. by eval().) The optional second argument is the regex syntax variant to be used. This is an integer mask as passed to regex.set_syntax(); the flag bits are defined in regex_syntax. When not specified, or when None is given, the current regex syntax mask (as retrieved by regex.get_syntax()) is used -- which is 0 by default. The return value is a regular expression, as a string object that could be passed to re.compile(). (I.e., no string quotes have been added -- use quote() below, or repr().) The conversion is not always guaranteed to be correct. More syntactical analysis should be performed to detect borderline cases and decide what to do with them. For example, 'x*?' is not translated correctly. s \(s \)R R s \|R s \+t +s \?t ?s t i i s \N( t mastertablet copyt tablet syntaxt Nonet regext get_syntaxt RE_NO_BK_PARENSt RE_NO_BK_VBARt RE_BK_PLUS_QMt RE_NEWLINE_ORt rest it lent st endt ct keyt get( R R R R R R R R ( ( t /usr/lib/python2.4/reconvert.pyR Z sB c C sî | d j o4 d } d } | | j o | | j o | } q[ n | d j p t ‚ | } | } xa | D]Y } | | j o d | } n/ | d j p | d j o d t | ƒ } n | | } qh W| | } d | j o d | } n | S( s Convert a string object to a quoted string literal. This is similar to repr() but will return a "raw" string (r'...' or r"...") when the string contains backslashes, instead of doubling all backslashes. The resulting string does *not* always evaluate to the same string as the original; however it will do just the right thing when passed into re.compile(). The optional second argument forces the string quote; it must be a single character which is a valid Python string quote. t 't "s \t t ~s \%03ot rN( R R ( R R t qt altqR t AssertionErrorR R t ord( R R R R$ R R% ( ( R R – s( c C sb d k } t | i i ƒ ƒ } | i i t t | ƒ ƒ ƒ | i i ƒ o | i i d ƒ n d S( s, Main program -- called when run as a script.Ns ( t syst evalt stdint readR t stdoutt writeR R t isatty( R( R ( ( R t main¶ s t __main__( t __doc__t warningst filterwarningst DeprecationWarningt __name__R t regex_syntaxt __all__R R R R R/ ( R R R7 R2 R R R/ ( ( R R < s { <
