alphabetical

I have a large set of real-world text that I need to pull words out of to input into a spell checker. I'd like to extract as many meaningful words as possible without too much noise. I know there's plenty of regex ninjas around here, so hopefully someone can help me out. Currently I'm extracting all alphabetical sequences with '[a-z]+' . This is an okay approximation, but it drags a lot of rubbish out with it. Ideally I would like some regex (doesn't have to be pretty or efficient) that extracts all alphabetical sequences delimited by natural word separators (such as [/-_,.: ] etc.), and

I have been trying to get this working for a few hours now to no avail and the formula is getting quite complex and I'm not sure if there's a simpler way to do it. Thanks for reading. Edit: I have something like this at the moment but it's not quite there and I'm not sure if there is a better way: private IEnumerable<string> GetWordsOfLength(int

My purpose is to obtain something like that : But the only examples i can find are lists like that : android - listview fastscroll with alphabet like on iPhone contacts activity Obviously, I don't want a list like the contacts which displays the letters when you fastscroll. I know how to do this. Any pointer would be welcome. (I tried this but no success) Below, the full solution as suggest by FunkTheMonk (thanks a lot) : Define the listview as usual. Define a RelativeLayout containing the ListView and on the right, a LinearLayout with all the letters. For a better solution, the list of

Does anyone know of a Javascript library (e.g. underscore, jQuery, MooTools, etc.) that offers a method of incrementing a letter? I would like to be able to do something like: "a"++; // would return "b" Simple, direct solution function nextChar(c) { return String.fromCharCode(c.charCodeAt(0) + 1); } nextChar('a'); As others have noted, the drawback is it may not handle cases like the letter 'z' as expected. But it depends on what you want out of it. The solution above will return '{' for the character after 'z', and this is the character after 'z' in ASCII, so it could be the result you're
