• Regex in JavaScript

  - by dfjhdfjhdf

  Suppose we don't know how many slashes we could get in a string but we do not want any extra slashes. So if we get this string '/hello/world///////how/are/you//////////////' we should transform it to the form of '/hello/world/how/are/you/'. How to do it with the help of regular expressions in JavaScript?

• Haskell: Gluing a char and a list together?

  - by Vincent

  So I have this code here: toWords :: String - [a] toWords "" = [] toWords (nr1 : rest) | nr1 == ' ' = toWords rest | otherwise = nr1 : toWords rest The "toWords" function should simply remove all spaces and return a list with all the words. But I keep getting this error: test.hs:5:18: Couldn't match expected type a' against inferred typeChar' `a' is a rigid type variable bound by the type signature for `toWords' at test.hs:1:22 In the first argument of `(:)', namely `nr1' In the expression: nr1 : toWords rest In the definition of `toWords': toWords (nr1 : rest) | nr1 == ' ' = toWords rest | otherwise = nr1 : toWords rest Failed, modules loaded: none.

• Checking an empty Core Data relationship (SQLite)

  - by rwat

  I have a to-many relationship in my data model, and I'd like to get all the objects that have no corresponding objects in the relationship. For example: Customer - Purchases I want to get all Customers that have 0 Purchases. I've read somewhere that I could use "Purchases[SIZE] = 0", but this gives me an unsupported function expression error, which I think means it doesn't work with a SQLite backing store (which I don't want to switch from, due to some performance constraints). Any ideas?

• How to replace only part of the match with python re.sub

  - by Arty

  I need to match two cases by one reg expression and do replacement 'long.file.name.jpg' - 'long.file.name_suff.jpg' 'long.file.name_a.jpg' - 'long.file.name_suff.jpg' I'm trying to do the following re.sub('(\_a)?\.[^\.]*$' , '_suff.',"long.file.name.jpg") But this is cut the extension '.jpg' and I'm getting long.file.name_suff. instead of long.file.name_suff.jpg I understand that this is because of [^.]*$ part, but I can't exclude it, because I have to find last occurance of '_a' to replace or last '.' Is there a way to replace only part of the match?

• Horizontal scrolling in a wx.RichTextCtrl

  - by Sam

  I have a RichTextCtrl created as follows: self.userlist = wx.richtext.RichTextCtrl(self, style=wx.TE_MULTILINE|wx.TE_READONLY|wx.HSCROLL) It all works fine, except for the wx.HSCROLL style. If I change the RichTextCtrl to a regular TextCtrl, it correctly horizontal scrolls on long lines, rather than wrapping, but on the RichTextCtrl it wraps regardless. Is there an easy way to make it scroll horizontally? (I do, unfortunately, need the RichTextCtrl's featureset for this object.)

• Javascript - proper getAttributeNode on IE6+

  - by Darrow

  I have a regular input box (no onchange attribute). <input type="text" id="bar" name="bar" /> For some reason, IE6+ does returns [object], while FF and Chrome returns null. if ((elem.getAttributeNode('onchange')) != null) elem.onchange(); I did also try as: if (typeof(elem.onchange) !== 'undefined') elem.onchange(); What would be the proper cross-browser way to check if the element has the attribute? Thanks

• Is web-browser to Excel interprocess communication possible

  - by Abiel

  Is is possible to write a browser plugin (one that requires the user to install something is OK) that would allow interprocess communication between the browser and a running instance of Excel (on Windows)? For example, suppose I want the user to be able to click something within their browser, and then have a piece of text drop into the selected cell in Excel as a result. This is certainly possible to do with a regular desktop application and Excel, but I'm not sure if it is possible with a browser, for security reasons.

• Way to partialy match a Ruby string using Regexp

  - by Fabiano PS

  I'm working on 2 cases: assume I have those var: a = "hello" b = "hello-SP" b = "not_hello" 1 - Any partial matches I want to accept any string that has the var a inside, so b and c would match. 2 - Patterned match I want to match a string that has a inside, followed by '-', so b would match, c does not. I am having problem, because I always used the syntax /expression/ to define Regexp, so how dinamicaly define an RegExp on Ruby??

• What is the one programming skill you have always wanted to master but haven't had time?

  - by KevDog

  For me, I've always wanted to finish the O'Reilly "Mastering Regular Expressions" book. When I need a Regexp, I manage to get the one I need eventually, but it takes more effort than it should. Learning a specific technology or language always seems to bubble up ahead of this.

• Merging .NET assemblies on Windows Store / Phone 8 / Portable Class Library

  - by Gabriel S.

  Is there a way to embed multiple dependent assemblies into a single one for projects written on the following platform types: Windows Store Apps, Windows Phone 8, Portable Class Library? I know that for regular .Net projects there is ILMerge, but on the aforementioned project types it doesn't work. Embedding assemblies as resources and then manually resolving the references using AppDomain.CurrentDomain.AssemblyResolve is not possible either, since AppDomain is not available in these types of project.

• "this" in function parameter

  - by chris

  Looking at some code examples for HtmlHelpers, and I see declarations that look like: public static string HelperName(this HtmlHelper htmlHelper, ...more regular params ) I can't remember seeing this type of construct any where else - can someone explain the purpose of the "this"? I thought that by declaring something public static meant that the class did not need to be instantiated - so what is "this" in this case?
