The standard ecmascript regex isn’t ready for unicode (see http://blog.stevenlevithan.com/archives/javascript-regex-and-unicode). So you have to use an external regex library. I used this one (with the unicode plugin) in the past : http://xregexp.com/ In your case, you may have to escape the char é as \u00E9 and defining a range englobing e, é, ê, etc. EDIT … Read more
To prevent it from being set in the first place, you can return false on the keydown event handler, thus preventing the event from propagating any further. I wrote the example below using jQuery, but you can use the same function when binding traditionally. Though it’s important to validate on the server-side as well, client-side … Read more
On refiddle.com set to JavaScript, try using this pattern /\|(?![^{]*})/g with this text word1 | {word2 | word3 } | word 4 | word 4 | {word2 | word3 } This should match all of the Pipe symbols that are not inside {}.
Here is one way one can grab the RewriteBase in an environment variable which you can then use in your other rewrite rules: RewriteCond %{REQUEST_URI}::$1 ^(.*?/)(.*)::\2$ RewriteRule ^(.*)$ – [E=BASE:%1] Then you can use %{ENV:BASE} in your rules to denote RewriteBase, i.e.: #redirect in-existent files/calls to index.php RewriteCond %{REQUEST_FILENAME} !-f RewriteRule . %{ENV:BASE}/index.php [L] Explanation: … Read more
I think you want preg_split. list($year, $month, $day, $hour, $min, $sec) = preg_split(‘/[: -]/’, $post_timestamp);
There are a couple of different ways of going about something like this, I’ll give two quick approaches for you to choose from: quick and dirty, versus longer and less dirty (though, it’s a Friday night so we’re allowed to go a little bit crazy). 1. Quick (and dirty) This involves just writing a regular … Read more
Use backrefrences echo preg_replace(“/(.)\\1+/”, “$1”, “cakkke”); Output: cake Explanation: (.) captures any character \\1 is a backreferences to the first capture group. The . above in this case. + makes the backreference match atleast 1 (so that it matches aa, aaa, aaaa, but not a) Replacing it with $1 replaces the complete matched text kkk … Read more
The syntax of your unicode range will not do what you expect. The raw r” string prevents \u escapes from being parsed, and the regex engine will not do this. The only range in this set is [0-\]: >>> re.compile(r'[\u0020-\u00d7ff]’, re.DEBUG) in literal 117 literal 48 literal 48 literal 50 range (48, 117) literal 48 … Read more
There is text2re, a free web-based “regex by example” generator. I don’t think this is available in source code, though. I dare to say there is no automatic regex generator that gets it right without user intervention, since this would require the machine knowing what you want. Note that text2re uses a template-based, modularized and … Read more
. ^ $ | ( ) [ ] { } * + ? \ Ironically, you could use a regex to escape your URL so that it can be inserted into a regex. const boost::regex esc(“[.^$|()\\[\\]{}*+?\\\\]”); const std::string rep(“\\\\&”); std::string result = regex_replace(url_to_escape, esc, rep, boost::match_default | boost::format_sed); (The flag boost::format_sed specifies to use the … Read more
