Please note that this message will contain a full copy of the comment thread, including the initial issue submission, for this request, not just the latest update. Category: Regular Expressions Group: None Status: Open Resolution: None Priority: 6 Submitted By: gmarketer (gmarketer) Assigned to: Nobody/Anonymous (nobody) Summary: New sequences for Unicode groups and block ranges needed Initial Comment: The special sequences consist of "\" and another character need to be added to RE sintax to simplify the finding of several Unicode classes like: * All uppercase letters * All lowercase letters ---------------------------------------------------------------------- >Comment By: Martin v. Löwis (loewis) Date: 2006-09-10 12:36 Message: Logged In: YES user_id=21627 If anything, I think Python should implement Unicode TR#18: http://www.unicode.org/unicode/reports/tr18/ This does include the \p notation for property expressions, e.g. \p{Ll} or \p{East Asian Width:Narrow}. We currently don't include the Script property, so \p{Greek} could not be implemented (we can, of course, add support for the script property). I can't find anything in the report that makes \p{IsGreek} valid, so we shouldn't support it. ---------------------------------------------------------------------- Comment By: gmarketer (gmarketer) Date: 2006-07-26 04:06 Message: Logged In: YES user_id=1334865 We need to process several strings in utf-8 and need to use regular expressions to match pattern, for ex.: r"[ANY_LANGUAGE_UPPERCASE_LETTER,0-9ANY_LANGUAGE_LOWERCASE_LETTER]+|NOT_ANY_LANGUAGE_CURRENCY" We don't know how to implement this logic by our hands. Also, I found this logic implemented in Microsoft dot NET regular expressions: \p{name} Matches any character in the named character class 'name'. Supported names are Unicode groups and block ranges. For example Ll, Nd, Z, IsGreek, IsBoxDrawing, and Sc (currency). \P{name} Matches text not included in the named character class 'name'. We need same logic in regular expressions. ---------------------------------------------------------------------- Comment By: M.-A. Lemburg (lemburg) Date: 2006-07-25 09:45 Message: Logged In: YES user_id=38388 Could you make your request a little more specific ? We already have catregories in the re module, so adding a few more would be possible (patches are welcome !). However, we do need to know why you need them and whether there are other RE implementations that already have such special matching characters, e.g. the Perl RE implementation. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=355470&aid=1528154&group_id=5470 _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
