• ASP.NET MVC routing issue: How to allow "\" in id's

  - by Bipul

  I am using following route map routes.MapRoute( "RenderAssociatedForm", "DoAction/{nodeLevelId}/{nodeSystemId}", new { controller = "FrontEnd", action = "RenderAssociatedForm", }); Now nodeLevelId can be anything like zs\bbal. As we know that we should escape '\', so we are using 'zs%5cbbal'. But still the following url is not mapping to this route. //localhost/DoAction/zs%5cbbal/5 When I try simple Id without the escape character, it maps properly. Can anybody tell me where I am going wrong?

• Scala println in a for loop

  - by random459

  The following Scala code does just what I expect it to - it prints each line of some_file.txt. import scala.io.Source val lines = Source.fromPath("some_file.txt").mkString for (line <- lines) print(line) If I use println instead of print, I expect to see some_file.txt printed out with double-spacing. Instead, the program prints a newline after every character of some_file.txt. Could someone explain this to me? I'm using Scala 2.8.0 Beta 1.

• How Do I grep For non-ASCII Characters in UNIX

  - by Peter Conrey

  I have several very large XML files and I'm trying to find the lines that contain non-ASCII characters. I've tried the following: grep -e "[\x{00FF}-\x{FFFF}]" file.xml But this returns every line in the file, regardless of whether the line contains a character in the range specified. Do I have the syntax wrong or am I doing something else wrong? I've also tried: egrep "[\x{00FF}-\x{FFFF}]" file.xml (with both single and double quotes surrounding the pattern).

  I am going to have different classes for a character that a user play.

• Is there an extension or mode in Emacs similar to surround.vim?

  - by Chow

  Surround.vim is a nifty vim extension that allows you to surround blocks of text with , brackets, braces, and pretty much any arbitrary "surround" character. It supports paragraph and word surround, but I frequently use it in visual mode. I'm playing around with Emacs and wondering if there's something similar; something that will let me highlight a region and then have the marked region (or rectangle) enclosed with braces, brackets or tags.
