string-parsing

Given URI strings like: http://www.somesite.com/abc http://www.somesite.com/alpha/beta/abc http://www.somesite.com/alpha/abc What's the most elegant way in Ruby to grab the abc at the end of these URIs? I would use a proper URI parser like the one of the URI module to get the path from the URI. Then split it at / and get the last part of it: require 'uri' URI(uri).path.split('/').last saihgala uri.split('/')[-1] or uri.split('/').last Try these: if url =~ /\/(.+?)$/ last = $1 end Or last = File.basename(url) From the Terminal command line: ruby -ruri -e "print File.basename(URI.parse('$URI')

I want to change persian numbers which are saved in variable like this : string Value="۱۰۳۶۷۵۱"; to string Value="1036751"; How can I use easy way like culture info to do this please? my sample code is: List<string> NERKHCOlist = new List<string>(); NERKHCOlist = ScrappingFunction(NERKHCO, NERKHCOlist); int NERKHCO_Price = int.Parse(NERKHCOlist[0]);//NERKHCOlist[0]=۱۰۳۶۷۵۱ <= So it can not Parsed it to int And This is in my function which retun a list with persian digits inside list items protected List<string> ScrappingFunction(string SiteAddress, List<string> NodesList) { string Price =

I know variants of this question have been asked frequently before (see here and here for instance), but this is not an exact duplicate of those. I would like to check if a String is a number, and if so I would like to store it as a double . There are several ways to do this, but all of them seem inappropriate for my purposes. One solution would be to use Double.parseDouble(s) or similarly new BigDecimal(s) . However, those solutions don't work if there are commas present (so "1,234" would cause an exception). I could of course strip out all commas before using these techniques, but that would

i'm trying to write in text file sentences that contains Arabic and English but the problem that both languages have direction RTL and LTR so the output text file don't save the order of the words and some words come before each other that is wrong, the problem fixed when i change the text direction from the notepad or any text editor, is there any way to fix this using java? As I explained in my comment on your previous question, Unicode text files store the characters in logical order. There is a documented algorithm for how to handle bidirectional text, and control characters you can insert

I am testing out std::stoi function found in the link below: http://en.cppreference.com/w/cpp/string/basic_string/stol but I got the error: No Member named stoi in namespace std. What should I do? Please advise thanks. P.S: I am using Xcode Ide to do my c++. #include <iostream> #include <string> int main() { std::string test = "45"; int myint = std::stoi(test); std::cout << myint << '\n'; } Image First of all, you need a compiler that supports C++11 and you need to compile in "C++11 mode" (in some cases). Secondly, if this is in fact an intellisense issue (and it looks like it may be), then it
