  • Finding C#-style unescaped strings using regular expressions

    - by possan
    I'm trying to write a regular expression that finds C#-style unescaped strings, such as string x = @"hello world"; The problem I'm having is how to write a rule that handles double quotes within the string correctly, like in this example string x = @"before quote ""junk"" after quote"; This should be an easy one, right?

  • Is there a way to look up the Publishers URL using the linkshare.com API

    - by steve
    I'm able to retrieve the URL of a publisher only if their URL is in the title or the description using regular expression in linkshare's coupon API but in doing so, that leaves me with a lot of publishers not having a reference to their website which I need for the type of site that I am building. I was wondering if anyone else knows a way to reference the publishers URL preferably by their publisher ID or some other way?

  • How to match a variable list of items separated by commas

    - by user261915
    I want to turn something like this CS 240, CS 246, ECE 222, ... (more or less); Software Engineering students only into ('CS 240', 'CS 246', 'ECE 222', 'ECE 220') in Python, code that matches a single course looks like >>> re.search('([A-Z]{2,5} \d{3})', 'SE 112').groups() ('SE 112',) I prefer a regular expression only method because I have a bunch of other alternate reg exps using '|' to combine them. However, a method with split is acceptable.

  • "Slice" out one element from a python dictionary

    - by BCS
    I have a dictionary: D = { "foo" : "bar", "baz" : "bip" } and I want to create new dictionary that has a copy of one of it's elements k. So if k = "baz": R = { "baz" : "bip" } what I'v got now is: R = { k : D[k] } But in my case k is a complex expression and I've got a whole stack of these. Caching k in a temporary looks about as ugly as the original option. What I'm looking for is a better (cleaner) way to do this.

  • why jquery can't be used in my $(document).ready() function?

    - by Firegun
    The page can be viewed at http://cistrome.org/cps/seqconfig?did=2693 When load in Firebugs, it gives me this error: TypeError: $(".open_gene").on is not a function [Break On This Error] $(".open_gene").on('change', function(event) { However, if I type in this expression in Firebug's console, it can be evaluated as a function without any problems: >>> $(".open_gene").on function() I was wondering what might be the reason to cause this issue. Does anyone have ideas about this? Thanks!

  • How to match !x but not !!x in JS regex?

    - by mpeterson
    Given the following text: This is!!xa simple string!xpattern I would like to get a regexp that matches the !x that's between "string" and "pattern" but not !!xa that's between "is" and "a". This regexp is to be used inside a string split(). I have tried several combinations but I cannot get a regexp that meets my needs. Perhaps my expression is not so regular after all =) Thanks in advance!

  • python copytree with negated ignore pattern

    - by Chris H
    I'm trying to use python to copy a tree of files/directories. is it possible to use copytree to copy everything that ends in foo? There is an ignore_patterns patterns function, can I give it a negated regular expression? Are they supported in python? eg. copytree(src, dest, False, ignore_pattern('!*.foo')) Where ! means NOT anything that ends in foo. thanks.

  • C++ Question on the pow function.

    - by Sagistic
    I'm trying to get this expression to work, I'm pretty sure its not the parenthesis because I counted all of them. Perhaps there something I'm doing wrong involving the parameter pow (x,y). double calculatePeriodicPayment() { periodicPaymentcalc = (loan * ((interestRate / yearlyPayment))) / (1-((pow ((1+(interestRate / yearlyPayment)))),(-(yearlyPayment * numOfYearLoan)))); return periodicPaymentcalc; }

  • Limits of GUIs in C#

    - by xarzu
    What are the limits of writing a C# app when you want a truly impressive GUI? At what point does one have to leave Visual C# behind and go into WPF? Also, if I choose to go with WPF, do I have to ditch the Visual Studio IDE and go with Expression Studio?

  • LINQ display row numbers

    - by timvaines
    I simply want to include a row number against the returned results of my query. I found the following post that describes what I am trying to achieve but gives me an exception http://vaultofthoughts.net/LINQRowNumberColumn.aspx "An expression tree may not contain an assignment operator" In MS SQL I would just use the ROWNUMBER() function, I'm simply looking for the equivalent in LINQ.

  • Identify differences between MP3 files

    - by Thingomy
    I have 2 old similar directory trees with MP3 files in them. I am happily using tools like diff and Rsync to identify and merge the files that are only present on one side, or are identical, I'm left with a bunch of files that are bitwise different. On running diff over a pair actually different files, (with -a tag to force text analysis) it produces incomprehensible gibberish. I have listened to files from both sides, and they both seem to play fine (but at nearly 10 minutes per song, when listening to them twice each, I haven't done many) I suspect the differences are due to some player in the past "enhancing" my collection by messing about with ID3 tags, but I can't be certain. Even if I identify differences in ID3 tags, I would like to confirm that no cosmic ray or file copy error issues have damaged any of the files. One method that occurs to be is finding the byte locations of the differences, and ignoring all changes in the first ~10kb of each file, but I don't know how to do this. I have on the order of a hundred or so files that differ across the directory tree. I found How to compare mp3, flac audio data in a file, ignoring header data (ID3 tag) etc.? -- but I can't run alldup due to being Linux only, and from the sounds of it, it would only partially solve my issues anyway.

  • Performance associated with storing millions of files on NTFS

    - by Tim Brigham
    Does anyone have a method / formula, etc that I could use - hopefully based on both current and projected numbers of files - to project the 'right' length of the split and the number of nested folders? Please note that although similar it isn't quite the same as Storing a million images in the filesystem. I'm looking for a way to help make the theories outlined more generic. Assumptions I have 'some' initial number of files. This number would be arbitrary but large. Say 500k to 10m+. I have considered the underlying physical hardware disk IO requirements that would be necessary to support such an endeavor. Put another way As time progresses this store will grow. I want to have the best balance of current performance and as my needs increase. Say I double or triple my storage. I need to be able to address both current needs and projected future growth. I need to both plan ahead and not sacrifice too much of current performance. What I've come up with I'm already thinking about using a hash split every so many characters to split things out across multiple directories and keeping the trees even, very similar as outlined in the comments in the question above. It also avoids duplicate files, which would be critical over time. I'm sure that the initial folder structure would be different based on what I've outlined, and depending on the initial scale. As far as I can figure there isn't a one size fits all solution here. It would be horrendously time intensive to work something out experimentally.

  • Web-based SVG or JavaScript Org Chart or Tree Graph Plotting Visualization API

    - by asoltys
    Hi, I'm looking to build an interactive web-based org chart for a large organization. I somewhat like the interface at ancestry.com where you can hover over people and pan/zoom around and click on different nodes to make them the root. Ideally, I'd like it if people could belong to multiple organizational entities like committees, working groups, etc. In other words the API should support graphs in general, not just trees. I'd like to be able to visually explode each organizational substructure into substituents by clicking on it, with a nice animation of the employees ballooning or spilling out so you can really interactively drill down through the organization. I found http://code.google.com/apis/visualization/documentation/gallery/orgchart.html but it looks a bit rudimentary. I know there are desktop tools like OrgPlus and Visio that can build static charts but I'm really looking for a free, web-based API with open standards-based output like SVG or HTML5 Canvas elements rather than Flash or some proprietary output. Something I can embed into a custom web application and style myself. Something interactive.

  • secure user-authentication in squid

    - by Isaac
    once upon a time, there was a beautiful warm virtual-jungle in south america, and a squid server lived there. here is an perceptual image of the network: <the Internet> | | A | B Users <---------> [squid-Server] <---> [LDAP-Server] When the Users request access to the Internet, squid ask their name and passport, authenticate them by LDAP and if ldap approved them, then he granted them. Everyone was happy until some sniffers stole passport in path between users and squid [path A]. This disaster happened because squid used Basic-Authentication method. The people of jungle gathered to solve the problem. Some bunnies offered using NTLM of method. Snakes prefered Digest-Authentication while Kerberos recommended by trees. After all, many solution offered by people of jungle and all was confused! The Lion decided to end the situation. He shouted the rules for solutions: Shall the solution be secure! Shall the solution work for most of browsers and softwares (e.g. download softwares) Shall the solution be simple and do not need other huge subsystem (like Samba server) Shall not the method depend on special domain. (e.g. Active Directory) Then, a very resonable-comprehensive-clever solution offered by a monkey, making him the new king of the jungle! can you guess what was the solution? Tip: The path between squid and LDAP is protected by the lion, so the solution have not to secure it. Note: sorry for this boring and messy story! /~\/~\/~\ /\~/~\/~\/~\/~\ ((/~\/~\/~\/~\/~\)) (/~\/~\/~\/~\/~\/~\/~\) (//// ~ ~ \\\\) (\\\\( (0) (0) )////) (\\\\( __\-/__ )////) (\\\( /-\ )///) (\\\( (""""") )///) (\\\( \^^^/ )///) (\\\( )///) (\/~\/~\/~\/) ** (\/~\/~\/) *####* | | **** /| | | |\ \\ _/ | | | | \_ _________// Thanks!
