  • Regular expression to extract text between either square or curly brackets

    - by ObiWanKenobi
    Related to my previous question, I have a string on the following format: this {is} a [sample] string with [some] {special} words. [another one] What is the regular expression to extract the words within either square or curly brackets, ie. {is} [sample] [some] {special} [another one] Note: In my use case, brackets cannot be nested. I would also like to keep the enclosing characters, so that I can tell the difference between them when processing the results.

  • What does the * symbol do near a function argument and how to use that in others scenarios?

    - by user502052
    I am using Ruby on Rails 3 and I would like to know what means the presence of a *simbol near a function argument and to understand its usages in others scenarios. Example scenario (this method was from the Ruby on Rails 3 framework: def find(*args) return to_a.find { |*block_args| yield(*block_args) } if block_given? options = args.extract_options! if options.present? apply_finder_options(options).find(*args) else case args.first when :first, :last, :all send(args.first) else find_with_ids(*args) end end end

  • How to install a Linux Rails gem on Windows

    - by Mike Sutton
    I need to upload vendorize a gem which is causing problems at my host - in this case nokogiri. My host is using linux, my development system is windows. The gem contains binaries and so my local gem downloads the win32 binaries. Is there any way I can get gem to download the linux binaries, so I can vendorize and upload them?

  • Compiling LaTex bib source

    - by Klaus
    Hi I am writing my thesis in Latex, and I have the references in an own thesis.bib file which look as follows @Article{xxx, author = "D.A. Reinhard", title = "Case Study", year = "1985", } and I reference them in my main document as ~\cite{xxx} When I compile then the main document with: pdflatex main.tex than it shows me question marks instead of the proper references to the bibliography. Do I also need to compile the bib source on its own? If yes, can somebody please tell me the command for Linux Many thanks!

  • Problem with jQuery.ajax with 'delete' method in ie

    - by Max Williams
    I have a page where the user can edit various content using buttons and selects that trigger ajax calls. In particular, one action causes a url to be called remotely, with some data and a 'put' request, which (as i'm using a restful rails backend) triggers my update action. I also have a delete button which calls the same url but with a 'delete' request. The 'update' ajax call works in all browsers but the 'delete' one doesn't work in IE. I've got a vague memory of encountering something like this before...can anyone shed any light? here's my ajax calls: //update action - works in all browsers jQuery.ajax({ async:true, data:data, dataType:'script', type:'put', url:"/quizzes/"+quizId+"/quiz_questions/"+quizQuestionId, success: function(msg){ initializeQuizQuestions(); setPublishButtonStatus(); } }); //delete action - fails in ie function deleteQuizQuestion(quizQuestionId, quizId){ //send ajax call to back end to change the difficulty of the quiz question //back end will then refresh the relevant parts of the page (progress bars, flashes, quiz status) jQuery.ajax({ async:true, dataType:'script', type:'delete', url:"/quizzes/"+quizId+"/quiz_questions/"+quizQuestionId, success: function(msg){ alert("success"); initializeQuizQuestions(); setSelectStatus(quizQuestionId, true); jQuery("tr[id*='quiz_question_"+quizQuestionId+"']").removeClass('selected'); }, error: function(msg){ alert("error:" + msg); } }); } I put the alerts in success and error in the delete ajax just to see what happens, and the 'error' part of the ajax call is triggered, but WITH NO CALL BEING MADE TO THE BACK END (i know this by watching my back end server logs). So, it fails before it even makes the call. I can't work out why - the 'msg' i get back from the error block is blank. Any ideas anyone? Is this a known problem? I've tested it in ie6 and ie8 and it doesn't work in either. thanks - max EDIT - the solution - thanks to Nick Craver for pointing me in the right direction. Rails (and maybe other frameworks?) has a subterfuge for the unsupported put and delete requests: a post request with the parameter "_method" (note the underscore) set to 'put' or 'delete' will be treated as if the actual request type was that string. So, in my case, i made this change - note the 'data' option': jQuery.ajax({ async:true, data: {"_method":"delete"}, dataType:'script', type:'post', url:"/quizzes/"+quizId+"/quiz_questions/"+quizQuestionId, success: function(msg){ alert("success"); initializeQuizQuestions(); setSelectStatus(quizQuestionId, true); jQuery("tr[id*='quiz_question_"+quizQuestionId+"']").removeClass('selected'); }, error: function(msg){ alert("error:" + msg); } }); } Rails will now treat this as if it were a delete request, preserving the REST system. The reason my PUT example worked was just because in this particular case IE was happy to send a PUT request, but it officially does not support them so it's best to do this for PUT requests as well as DELETE requests.

  • Automatic database schema generation and migration with Perl

    - by pistacchio
    In Ror or Django or web2py you can "describe" a database (as a set of classes that remaps to tables) and the framework (having being provided with a connection string to the desired database) generates the tables, fields, relations and in the case of RoR and web2py it also keeps it up-to-date (eg, removing a class drops the table, adding a property to the class triggers an "alter table add" etc). Is there any Perl module that does the same? Eg, it takes the YAML/XML/JSON description of a database as input and modifies/generates the database schema accordingly?

  • Vim: how to make the text I've just typed uppercase?

    - by Pavel Shved
    Use case: I've just entered insert mode, and typed some text. Now I want to make it uppercase. It can be done via gUmotion. However, I can't find the motion over the text entered in the recent input session. It's somewhat strange and the concept of such motion is buggy (where to move if you've deleted text, for example?), but it may solve my problem. Or, are there other ways of making uppercase the text you've recently inputted?

  • Different behavior of functors (copies, assignments) in VS2010 (compared with VS2005)

    - by Patrick
    When moving from VS2005 to VS2010 we noticed a performance decrease, which seemed to be caused by additional copies of a functor. The following code illustrates the problem. It is essential to have a map where the value itself is a set. On both the map and the set we defined a comparison functor (which is templated in the example). #include <iostream> #include <map> #include <set> class A { public: A(int i, char c) : m_i(i), m_c(c) { std::cout << "Construct object " << m_c << m_i << std::endl; } A(const A &a) : m_i(a.m_i), m_c(a.m_c) { std::cout << "Copy object " << m_c << m_i << std::endl; } ~A() { std::cout << "Destruct object " << m_c << m_i << std::endl; } void operator= (const A &a) { m_i = a.m_i; m_c = a.m_c; std::cout << "Assign object " << m_c << m_i << std::endl; } int m_i; char m_c; }; class B : public A { public: B(int i) : A(i, 'B') { } static const char s_c = 'B'; }; class C : public A { public: C(int i) : A(i, 'C') { } static const char s_c = 'C'; }; template <class X> class compareA { public: compareA() : m_i(999) { std::cout << "Construct functor " << X::s_c << m_i << std::endl; } compareA(const compareA &a) : m_i(a.m_i) { std::cout << "Copy functor " << X::s_c << m_i << std::endl; } ~compareA() { std::cout << "Destruct functor " << X::s_c << m_i << std::endl; } void operator= (const compareA &a) { m_i = a.m_i; std::cout << "Assign functor " << X::s_c << m_i << std::endl; } bool operator() (const X &x1, const X &x2) const { std::cout << "Comparing object " << x1.m_i << " with " << x2.m_i << std::endl; return x1.m_i < x2.m_i; } private: int m_i; }; typedef std::set<C, compareA<C> > SetTest; typedef std::map<B, SetTest, compareA<B> > MapTest; int main() { int i = 0; std::cout << "--- " << i++ << std::endl; MapTest mapTest; std::cout << "--- " << i++ << std::endl; SetTest &setTest = mapTest[0]; std::cout << "--- " << i++ << std::endl; } If I compile this code with VS2005 I get the following output: --- 0 Construct functor B999 Copy functor B999 Copy functor B999 Destruct functor B999 Destruct functor B999 --- 1 Construct object B0 Construct functor C999 Copy functor C999 Copy functor C999 Destruct functor C999 Destruct functor C999 Copy object B0 Copy functor C999 Copy functor C999 Copy functor C999 Destruct functor C999 Destruct functor C999 Copy object B0 Copy functor C999 Copy functor C999 Copy functor C999 Destruct functor C999 Destruct functor C999 Destruct functor C999 Destruct object B0 Destruct functor C999 Destruct object B0 --- 2 If I compile this with VS2010, I get the following output: --- 0 Construct functor B999 Copy functor B999 Copy functor B999 Destruct functor B999 Destruct functor B999 --- 1 Construct object B0 Construct functor C999 Copy functor C999 Copy functor C999 Destruct functor C999 Destruct functor C999 Copy object B0 Copy functor C999 Copy functor C999 Copy functor C999 Destruct functor C999 Destruct functor C999 Copy functor C999 Assign functor C999 Assign functor C999 Destruct functor C999 Copy object B0 Copy functor C999 Copy functor C999 Copy functor C999 Destruct functor C999 Destruct functor C999 Copy functor C999 Assign functor C999 Assign functor C999 Destruct functor C999 Destruct functor C999 Destruct object B0 Destruct functor C999 Destruct object B0 --- 2 The output for the first statement (constructing the map) is identical. The output for the second statement (creating the first element in the map and getting a reference to it), is much bigger in the VS2010 case: Copy constructor of functor: 10 times vs 8 times Assignment of functor: 2 times vs. 0 times Destructor of functor: 10 times vs 8 times My questions are: Why does the STL copy a functor? Isn't it enough to construct it once for every instantiation of the set? Why is the functor constructed more in the VS2010 case than in the VS2005 case? (didn't check VS2008) And why is it assigned two times in VS2010 and not in VS2005? Are there any tricks to avoid the copy of functors? I saw a similar question at http://stackoverflow.com/questions/2216041/prevent-unnecessary-copies-of-c-functor-objects but I'm not sure that's the same question. Thanks in advance, Patrick

  • How to make a table, which is wider than screen size, scrollable and keep header row fixed?

    - by understack
    I've a table with 2 columns and each column is 800px wide. I want to show this table in 800x50 window. So there should be horizontal and vertical scrollbar to view complete table. While I've found few related solutions (this and this) on SO, they only work if table width is smaller than screen size. In my case screen size is 1200px and total table width is 1600px. How could I do this? i want to achieve something like this. EDIT Oops, I forgot to add one more requirement. Sorry. I want the header of the table to remain fixed while user scrolls table. EDIT2 I've tried below mentioned solutions to wrap in a div, but in this case vertical scrollbar doesn't show up. Please see this table with wrapper div. It seems this problem only occurs if table width is bigger than screen size. I'm testing on FF3.6. EDIT3 current table code: <div style="overflow:scroll; width:800px;height:50px" > <table style="width:1600px" border="1"> <thead> <tr> <th style="width:800px">id_1</th> <th style="width:800px">id_1</th> </tr> </thead> <tbody style=""> <tr><td>1200</td><td>1200</td></tr> <tr><td>1200</td><td>1200</td></tr> <tr><td>1200</td><td>1200</td></tr> <tr><td>1200</td><td>1200</td></tr> <tr><td>1200</td><td>1200</td></tr> <tr><td>1200</td><td>1200</td></tr> </tbody> </table> </div>

  • How to copy matplotlib figure?

    - by Alex
    I have FigureCanvasWxAgg instance with a figure displayed on a frame. If user clicks on the canvas another frame with a new FigureCanvasWxAgg containing the same figure will be shown. By now closing the new frame can result in destroying the C++ part of the figure so that it won't be available for the first frame. How can I save the figure? Python deepcopy from copy module does't work in this case. Thanks in advance.

  • JPA - How to truncate tables between unit tests

    - by Theo
    I want to cleanup the database after every test case without rolling back the transaction. I have tried DBUnit's DatabaseOperation.DELETE_ALL, but it does not work if a deletion violates a foreign key constraint. I know that I can disable foreign key checks, but that would also disable the checks for the tests (which I want to prevent). I'm using JUnit 4, JPA 2.0 (Eclipselink), and Derby's in-memory database. Any ideas? Thanks, Theo

  • Corner Cases, Unexpected and Unusual Matlab

    - by Mikhail
    Over the years, reading others code, I encountered and collected some examples of Matlab syntax which can be at first unusual and counterintuitive. Please, feel free to comment or complement this list. I verified it r2006a. set([], 'Background:Color','red') Matlab is very forgiving sometimes. In this case, setting properties to an array of objects works also with nonsense properties, at least when the array is empty. myArray([1,round(end/2)]) This use of end keyword may seem unclean but is sometimes very handy instead of using length(myArray). any([]) ~= all([]) Surprisigly any([]) returns false and all([]) returns true. And I always thought that all is stronger then any. EDIT: with not empty argument all() returns true for a subset of values for which any() returns true (e.g. truth table). This means that any() false implies all() false. This simple rule is being violated by Matlab with [] as argument. Loren also blogged about it. Select(Range(ExcelComObj)) Procedural style COM object method dispatch. Do not wonder that exist('Select') returns zero! [myString, myCell] Matlab makes in this case an implicit cast of string variable myString to cell type {myString}. It works, also if I would not expect it to do so. [double(1.8), uint8(123)] => 2 123 Another cast example. Everybody would probably expect uint8 value being cast to double but Mathworks have another opinion. a = 5; b = a(); It looks silly but you can call a variable with round brackets. Actually it makes sense because this way you can execute a function given its handle. a = {'aa', 'bb' 'cc', 'dd'}; Surprsisingly this code neither returns a vector nor rises an error but defins matrix, using just code layout. It is probably a relict from ancient times. set(hobj, {'BackgroundColor','ForegroundColor'},{'red','blue'}) This code does what you probably expect it to do. That function set accepts a struct as its second argument is a known fact and makes sense, and this sintax is just a cell2struct away. Equvalence rules are sometimes unexpected at first. For example 'A'==65 returns true (although for C-experts it is self-evident). About which further unexpected/unusual Matlab features are you aware?

  • Inherited TShape.Paint does not work after overriding Shape property

    - by DarkWalker
    I'm to code a TExpandedShape class inherited from TShape. TExpandedShape must act like TShape and be able to draw extra shapes: Polygon and Star. Here is my code unit ExpandedShape; interface uses SysUtils, WinTypes, WinProcs, Messages, Classes, Graphics, Controls, Forms, Dialogs, ExtCtrls, Windows; type TExpandedShapeType = ( stRectangle, stSquare, stRoundRect, stRoundSquare, stEllipse, stCircle, stPolygon, stStar ); TExpandedShape = class(TShape) private FShape: TExpandedShapeType; FEdgeCount: integer; procedure SetShape(const Value: TExpandedShapeType); procedure SetEdgeCount(const Value: integer); public procedure Paint; override; published property Shape : TExpandedShapeType read FShape write SetShape;// default stPolygon; property EdgeCount : integer read FEdgeCount write SetEdgeCount default 5; end; procedure Register; implementation procedure Register; begin RegisterComponents('Course', [TExpandedShape]); end; // TExpandedShape procedure TExpandedShape.Paint; begin case Shape of stStar : begin {Draw Star} end; stPolygon : begin {Draw Polygon} end; else begin {It is supposed to draw Circle, Rectangle etc, but it does not} inherited; end; end; end; procedure TExpandedShape.SetEdgeCount(const Value: integer); begin FEdgeCount := Value; Repaint; end; procedure TExpandedShape.SetShape(const Value: TExpandedShapeType); begin FShape := Value; Repaint; end; end. So, what is wrong? IMO TShape.Paint checks private value like FShape in case section and then decides what to draw. When inherited Paint method is called in my code it checks FShape value sees default 0 value [stRectangle] in there and draws it. PS: I did solve it with blackmagic way using Shape1 property instead of Shape one and if Shape1 value is not stPolygon or stStar i do like this: begin Shape := TShapeType(Shape1); inherited end; But this option is not really an option. I need a good short nice-looking one.

    Hi all! I want to make an import script which allows users to upload their excel file (extension not important) to my php application. The application should reconize a list of items (so far so good). The difficulty in this case is that the excel files contain images...I've read information about phpexcel library but it does not say anything about images. Anybody ideas? Regards, Marcel

  • How do I refactor these two C# functions to abstrtact their logic from the specific class properties

    - by ObligatoryMoniker
    I have two functions whose underlying logic is the same but in one case it sets one property value on a class and in another case it sets a different one. How can I rewrite the following two functions to abstract away as much of the algorithm as possible so that I can make changes in logic in a single place? SetBillingAddress private void SetBillingAddress(OrderAddress newBillingAddress) { BasketHelper basketHelper = new BasketHelper(SiteConstants.BasketName); OrderAddress oldBillingAddress = basketHelper.Basket.Addresses[basketHelper.BillingAddressID]; bool NewBillingAddressIsNotOldBillingAddress = ((oldBillingAddress == null) || (newBillingAddress.OrderAddressId != oldBillingAddress.OrderAddressId)); bool BillingAddressHasBeenPreviouslySet = (oldBillingAddress != null); bool BillingAddressIsNotSameAsShippingAddress = (basketHelper.ShippingAddressID != basketHelper.BillingAddressID); bool NewBillingAddressIsNotShippingAddress = (newBillingAddress.OrderAddressId != basketHelper.ShippingAddressID); if (NewBillingAddressIsNotOldBillingAddress && BillingAddressHasBeenPreviouslySet && BillingAddressIsNotSameAsShippingAddress) { basketHelper.Basket.Addresses.Remove(oldBillingAddress); } if (NewBillingAddressIsNotOldBillingAddress && NewBillingAddressIsNotShippingAddress) { basketHelper.Basket.Addresses.Add(newBillingAddress); } basketHelper.BillingAddressID = newBillingAddress.OrderAddressId; basketHelper.Basket.Save(); } And here is the second one: SetShippingAddress private void SetBillingAddress(OrderAddress newShippingAddress) { BasketHelper basketHelper = new BasketHelper(SiteConstants.BasketName); OrderAddress oldShippingAddress = basketHelper.Basket.Addresses[basketHelper.ShippingAddressID]; bool NewShippingAddressIsNotOldShippingAddress = ((oldShippingAddress == null) || (newShippingAddress.OrderAddressId != oldShippingAddress.OrderAddressId)); bool ShippingAddressHasBeenPreviouslySet = (oldShippingAddress != null); bool ShippingAddressIsNotSameAsBillingAddress = (basketHelper.ShippingAddressID != basketHelper.BillingAddressID); bool NewShippingAddressIsNotBillingAddress = (newShippingAddress.OrderAddressId != basketHelper.BillingAddressID); if (NewShippingAddressIsNotOldShippingAddress && ShippingAddressHasBeenPreviouslySet && ShippingAddressIsNotSameAsBillingAddress) { basketHelper.Basket.Addresses.Remove(oldShippingAddress); } if (NewShippingAddressIsNotOldShippingAddress && NewShippingAddressIsNotBillingAddress) { basketHelper.Basket.Addresses.Add(newShippingAddress); } basketHelper.ShippingAddressID = newShippingAddress.OrderAddressId; basketHelper.Basket.Save(); } My initial thought was that if I could pass a class's property by refernce then I could rewrite the previous functions into something like private void SetPurchaseOrderAddress(OrderAddress newAddress, ref String CurrentChangingAddressIDProperty) and then call this function and pass in either basketHelper.BillingAddressID or basketHelper.ShippingAddressID as CurrentChangingAddressIDProperty but since I can't pass C# properties by reference I am not sure what to do with this code to be able to reuse the logic in both places. Thanks for any insight you can give me.

  • Make HTML content area fit to viewport height?

    I just made this demo extracting out what I'm trying to accomplish: Autosize Main Content Area I want the pink/yellow area to act according to these rules: Minimum height is the size of its content (which is variable) IF content size is smaller than viewport size Otherwise minimum height is such that it adjusts to fill the window. Checking out the source to that demo, what am I missing? I feel like this is a pretty easy case that shouldn't require javascript. Any ideas?
