• Using jQuery to find keywords in string

  - by Nic Hubbard

  In php, I have used preg_match_all() to find keywords (using the format %keyword%) in a string, which works wonderfully and returns an array of all found keywords. What I would like to do, is do the same thing using jQuery or javascript. I have tried using the filter() function, and it kind of works. But I think I am missing something. How can I find ALL instances of the keyword in a string, using a regex? Here is what I have worked out so far: $("[id^='editableContent-']").filter(function() { alert($(this).html().match(/\%(.*?)\%/)); }); Any suggestions are welcome!

• PHP making input from web form case insensitive?

  - by Haskella

  So I have some code here that takes user input from a standard web form: $searchsport = $_POST['sport']; $sportarray = array( "Football" => "Fb01", "Cricket" => "ck32", "Tennis" => "Tn43", ); if(isset($sportarray[$searchsport])){ header("Location: ".$sportarray[$searchsport].".html"); die; } How would I go about modifying this (I think the word is parsing?) to make it case *in*sensitive? For example, I type in "fOoTbAlL" and php will direct me to Fb01.html normally.

• Mac OSX: Passing a file from user process to kernel module.

  - by Inso Reiges

  Hello, I need to pass a link to file from a user process to the OSX kernel driver. By link i mean anything that uniquely identifies a file on the local filesystem. I need that link to do I/O on that file in kernel. The most obvious solution seems to pass a file name and use a VFS vnode lookup. However i noticed, that Apple Disk Images helper process passes a raw data array for image-path property to driver when attaching a disk image file: <2f 56 6f 6c 75 6d 65 73 2f 73 74 6f 72 61 67 65 2f 74 65 73 74 32 2e 64 6d 67> What is that diskimages-helper passes to the kernel driver? Some serialized type perhaps? If yes, what type is it and how can i use it?

• Why "do...while" does not exist in F#

  - by Kev

  I cannot find "do...while..." I have to code like this: let bubbleSort a= let n = Array.length a let mutable swapped = true let mutable i = 0 while swapped do swapped <- false for j = 0 to n-i-2 do if a.[j] > a.[j+1] then let t = a.[j] a.[j] <- a.[j+1] a.[j+1] <- t swapped <- true i <- i+1 The code is bad without "do...while". Sadly, "break/continue" are also not available. Is F# not suitable for non-functional-programming?

• See if item exists once in Enumerable (Linq)

  - by Stacey

  Given a list... class Item { public Name { get; set; } } List<Item> items = new List<Item> { new Item() { Name = "Item 1" }, new Item() { Name = "Item 1" }, new Item() { Name = "Item 2" }, new Item() { Name = "Item 3" } } List<Item> listing = new List<Item> { new Item() { Name = "Item 1" }, new Item() { Name = "Item 2" }, new Item() { Name = "Item 3" } new Item() { Name = "Item 4" } } etc. I need to create a third array that will cancel out double instances between the two; however items with "Name 1" are both the same, but different 'instances'. So the third List should have 1 instance of Item 1, since 'items' had 2 instances. Any ideas of how this can be done through Linq?

• Jquery javascript - How can I let users 'undo' their modifications?

  - by Bill Zimmerman

  Hi, i have a basic jquery app that allows a user to edit and manipulate some lists on a page. What I would like to do is have a button 'restore original list' that the user can press to undo his modifications. What is the best way to do this? I was thinking of just copying the DOM from the list down, and pasting it in a hidden element someplace else on the page. Is this the best way to do this? I also noticed that jquery has a .data() function which I could use if I converted the data to an array and stored it this way. What are the advantages and disadvantages? Also, I'm open to any suggestions people have if there is some method I haven't thought of. Thanks for your help!

• Handling missing/incomplete data in R

  - by doug

  As you would expect from a DSL aimed at data analysts, R handles missing/incomplete data very well, for instance: Many R functions have an 'na.rm' flag that you can set to 'T' to remove the NAs, but if you want to deal with this before the function call, then: to replace each 'NA' w/ 0: ifelse(is.na(vx), 0, vx) to remove each 'NA': vx = vx[!is.na(a)] to remove entire each row that contains 'NA' from a data frame: dfx = dfx[complete.cases(dfx),] All of these functions remove 'NA' or rows with an 'NA' in them. Sometimes this isn't quite what you want though--making an 'NA'-excised copy of the data frame might be necessary for the next step in the workflow but in subsequent steps you often want those rows back (e.g., to calculate a column-wise statistic for a column that has missing rows caused by a prior call to 'complete cases' yet that column has no 'NA' values in it). to be as clear as possible about what i'm looking for: python/numpy has a class, 'masked array', with a 'mask' method, which lets you conceal--but not remove--NAs during a function call. Is there an analogous function in R?

• How to create list of numbers and append its reverse to it efficiently in Ruby

  - by Kiwi

  Given a minimum integer and maximum integer, I want to create an array which counts from the minimum to the maximum by two, then back down (again by two, repeating the maximum number). For example, if the minimum number is 1 and the maximum is 9, I want [1, 3, 5, 7, 9, 9, 7, 5, 3, 1]. I'm trying to be as concise as possible, which is why I'm using one-liners. In Python, I would do this: range(1, 10, 2) + range(9, 0, -2) In Ruby, which I'm just beginning to learn, all I've come up with so far is: (1..9).inject([]) { |r, num| num%2 == 1 ? r << num : r }.reverse.inject([]) { |r, num| r.unshift(num).push(num) } Which works, but I know there must be a better way. What is it?

• Best wrapper for simultaneous API requests?

  - by bluebit

  I am looking for the easiest, simplest way to access web APIs that return either JSON or XML, with concurrent requests. For example, I would like to call the twitter search API and return 5 pages of results at the same time (5 requests). The results should ideally be integrated and returned in one array of hashes. I have about 15 APIs that I will be using, and already have code to access them individually (using simple a NET HTTP request) and parse them, but I need to make these requests concurrent in the easiest way possible. Additionally, any error handling for JSON/XML parsing is a bonus.

• Overriding rubies spaceship operator <=>

  - by ericsteen1

  I am trying to override rubies <= (spaceship) operator to sort apples and oranges so that apples come first sorted by weight, and oranges second, sorted by sweetness. Like so: module Fruity attr_accessor :weight, :sweetness def <=>(other) # use Array#<=> to compare the attributes [self.weight, self.sweetness] <=> [other.weight, other.sweetness] end include Comparable end class Apple include Fruity def initialize(w) self.weight = w end end class Orange include Fruity def initialize(s) self.sweetness = s end end fruits = [Apple.new(2),Orange.new(4),Apple.new(6),Orange.new(9),Apple.new(1),Orange.new(22)] p fruits #should work? p fruits.sort But this does not work, can someone tell what I am doing wrong here, or a better way to do this?

• getting java.lang.OutOfMemoryError exception while running a Midlet (using netbeans)

  - by Jeeka

  I am writing a Midlet(using Netbeans) which reads a file containing exactly 2400 lines (each line being 32 characters long) and (extract a part of each line) puts them in an array. I am doing the same for 11 such files( all files have exactly 2400 lines).The Midlet runs fine for reading 6 files and putting them in 6 arrays. However, the Midlet stops while doing it for the 7th file throwing the following exception: TRACE: , startApp threw an Exception java.lang.OutOfMemoryError (stack trace incomplete) java.lang.OutOfMemoryError (stack trace incomplete) I have tried the modifying the netbeans.conf file to increase the heap memory ( as suggested by many forums and blogs) but nothing works for me. Here are the parameters that i had modified in the netbeans.conf file: -J-Xss2m -J-Xms1024m -J-Xmx1024m -J-XX:PermSize=1024m -J-XX:MaxPermSize=1536m -J-XX:+UseConcMarkSweepGC -J-XX:+CMSClassUnloadingEnabled -J-XX:+CMSPermGenSweepingEnabled Can anyone please help me to get me out of this !

• My Ruby Code: How can I improve? (Java to Ruby guy)

  - by steve

  Greetings, I get the feeling that I'm using ruby in an ugly way and possibly missing out on tonnes of useful features. I was wondering if anyone could point out a cleaner better way to write my code which is pasted here. The code itself simply scrapes some data from yelp and processes it into a json format. The reason I'm not using hash.to_json is because it throws some sort of stack error which I can only assume is due to the hash being too large (It's not particularly large). Response object = a hash text = the output which saves to file Anyways guidance appreciated. def mineLocation client = Yelp::Client.new request = Yelp::Review::Request::GeoPoint.new(:latitude=>13.3125,:longitude => -6.2468,:yws_id => 'nicetry') response = client.search(request) response['businesses'].length.times do |businessEntry| text ="" response['businesses'][businessEntry].each { |key, value| if value.class == Array value.length.times { |arrayEntry| text+= "\"#{key}\":[" value[arrayEntry].each { |arrayKey,arrayValue| text+= "{\"#{arrayKey}\":\"#{arrayValue}\"}," } text+="]" } else text+="\"#{arrayKey}\":\"#{arrayValue}\"," end } end end

• NSDictionary: Two keys per value?

  - by Derek

  I would like to create an NSDictionary (or something similar) that has two keys per value. It will be for English/Spanish word look-up, where: each value is an array containing all the conjugated verbs in English AND Spanish. each (two) keys contains both an English infinitive (e.g. "to be", "to go") and a Spanish infinitive This way, I can look a word up regardless of language based on the values having two keys per value. Here's an example: keys: "to want" or "querer" values: ["want", "want", "wants", "want", "want", "quiero", "quieres", "quiere", "queremos", "quieren"]

• Arrays in javascript, how can i learn manipulating it?

  - by Noor

  I've read alot about the core implementation of arrays in javascript and often i find that experimenting is the best way to learn, Right now i have multiple forms where you can type in different things, i want to be able to pull the value of each one and put it in an array so that i can later on read them in in a dynamically created div.. Can anyone point me in the right direction? There is a way i could get around this and that would be by using just one form, and pulling the text from there seperated by comas (,).. the thing is that i don't have the knowledge to pull the text form the form, search and find the comas, then make a new variable i think is neccessary, and read that in.. i know how to "think" javascript, not how to write it.. how do i learn the easiest/fastest way?

• url to http request object

  - by takeshin

  I need to convert string like this: $url = 'module/controller/action/param1/param1value/paramX/paramXvalue'; to url regarding current router (including translation and so on). Usually I generate the target urls using url view helper, but for this I need to specify all params, so I would need to manually explode the string. I tried to use request object, like this: $request = new Zend_Controller_Request_Http(); // some code here passing the $url Zend_Debug::dump($request->getControllerName()); // null instead of 'controllers' Zend_Debug::dump($request->getParams()); // null instead of array but this seems to be suspected. Do I need to dispatch this request? How to handle this case well?

• removing dashboard menu options for the user role editor

  I want to remove some of the dashboard menu tabs on my wordpress site using this code: //Remove some menu options function remove_menus () { global $menu; $restricted = array(__('Dashboard'), __('Posts'), __('Media'), __('Contact'), __('Links'), __('Pages'), __('Appearance'), __('Tools'), __('Users'), __('Settings'), __('Comments'), __('Plugins')); end ($menu); while (prev($menu)){ $value = explode(' ',$menu[key($menu)][0]); if(in_array($value[0] != NULL?$value[0]:"" , $restricted)){unset($menu[key($menu)]);} } } add_action('admin_menu', 'remove_menus'); At the moment this removes the menus from all user roles, how could I update this to just apply to editors? Ive also got this snippet of code but dont know how to combine it with what I have: $editor = get_role(‘editor’); $editor->remove_cap(‘publish_pages’);

• Sorting NSTableColumn contents

  - by Yahoo

  Hey, I have a problem with sorting NSTableColumn contents. In my NSTableView there are three columns: File, Size, Path. The contents are stored in NSMutableArray. Each object in this array is a NSDictionary containing three keys: file, size and path - value for each is a NSString. In Interface Builder, in each Table Column's attributes I can choose sorting options: Selector: IB entered "compare:" which I think is ok, because I compare NSStrings. Sort Key - and that's the problem I think - I don't know what to enter here. Any clues? If you've got questions about my code, please ask.
