• Most efficient approach for multilingual PHP website

  - by alexteg

  I am working on a large multilingual website and I am considering different approaches for making it multilingual. The possible alternatives I can think of are: The Gettext functions with generation of .po files One MySQL table with the translations and a unique string ID for each text PHP-files with arrays containing the different translations with unique string IDs As far as I have understood the Gettext functions should be most efficient, but my requirement is that it should be possible to change a text string in the original reference language (English) without the other translations of that string automatically reverting back to English just because a couple of words changed. Is this possible with Gettext? What is the least resource demanding solution? Is using the Gettext functions or PHP files with arrays more or less equally resource demanding? Any other suggestions for more efficient solutions?

• How to create a GUI inside a function in Matlab?

  - by Paperflyer

  Is there a possibility to write a GUI from inside a function? The Problem is: The callback of all GUI-functions work in the global workspace. But functions have their own workspace and can not access variables in the global workspace. Is there a possibility to make the GUI-functions use the workspace of the function? function myvar = myfunc() myvar = true; h_fig = figure; % create a useless button uicontrol( h_fig, 'style', 'pushbutton', ... 'string', 'clickme', ... 'callback', 'myvar = false' ); % wait for the button to be pressed while myvar pause( 0.2 ); end close( h_fig ); disp( 'this will never be displayed' ); end This event-loop will run indefinitely, since the callback will not modify myvar in the function. Instead it will create a new myvar in the global workspace.

• PL DOC source forge - 2 issues

  - by user1792793

  I'm attempting to use PLDOC source forge (http://pldoc.sourceforge.net/maven-site/) with my code to generate a neat page with comments of my liking. I'm coming across 2 issues, any help would be appreciated. 1 I've been using tags (/**, */) to make comments and this works perfectly for functions, but does not appear in procedures. My Functions and procedures are independent and not in packages, and trying to add comments before the PROCEDURE declaration just gets deleted when saved. 2 if i try to use the recommended method of getting the data directly from teh database (call pldoc.bat -url jdbc:oracle:thin:@localhost:1521:ORCL -user SCOTT -password TIGER -sql SYS_OWNER.DBMS_PIPE,SYS_OWNER.DBMS_OUTPUT), it puts all the available functions and procedures under the user SIS_OWNER (SIS_owner is the only link available on the left hand side). I want to change this so that I can view all the methods in the list instead. Problem with procedures stated in 1 still exists with this method. Please let me know if you have overcome this and any pointers would be great. Thanks

• Can GraphViz be used for a graph editing GUI?

  - by user185420

  I am creating an application which will allow a developer to create a program flow-chart by selecting pre-defined functions from a ToolBox (which will show up as small graphical elements). In other words, developer will select one or more pre-defined functions (graphical elements) from ToolBox and drag-drop on the main work area. The application will then, based on the flow of functions selected, will auto-generate ready-to-compile-code. I looked a GraphViz, but am not sure whether it can be used to create a GUI IDE for editing graphical elements. I am looking for a functionality similart to Microsoft Visio, where users can add/remove/drag-drop/ various shapes to create a diagram. Does GraphViz fit in here? If yes, can you direct me to some examples showing how to do it? If GraphViz cannot be used, what are the other open source/free components available? I am intending to build the final application in .Net.

• Is There A Central Repository of Javascript Information?

  - by Brian

  For example, if you want information of PHP functions, you can go to http://www.php.net/ . If you want information of Perl functions you can to to http://www.cpan.org/ and/or use perldoc. If you want information on Java you can go to http://java.sun.com and/or use javadoc. However, if you want information on Javascript methods/functions and their attributes, return values, etc. where do you go? The reason I ask is I was playing with the "focus()" method and wondering if it could be passed any values or if it returned anything when called. I have done a cursory Google search but haven't found much. Does such a beast exist or am I out of luck? Thanks for reading, and have a good day.

• Can any function be a deleted-function?

  - by Caspin

  The working draft explicitly calls out that defaulted-functions must be special member functions (eg copy-constructor, default-constructor, etc). Which makes perfect sense. However, I don't see any such restriction on deleted-functions. Is that right? Or in other words are these three examples valid c++0? struct Foo { // 1 int bar( int ) = delete; }; // 2 int baz( int ) = delete; template< typename T > int boo( T t ); // 3 template<> int boo<int>(int t) = delete;

• JavaScript helper libraries? No DOM or AJAX stuff

  - by Melmacian

  As I'm writing JavaScript I'm always missing some fairly basic language features that JavaScript just don't have. So is there any library that would bring such features as trim, sprintf, str.endwith and etc. functions to JavaScript ? I just have written those functions too many times and I'm also tired of copy/pasting them from my old code. It would be nice to have some library which has those implemented and tested in one place. Note that I'm not talking about Ajax/DOM-libraries like jQuery or Dojo and such. I know that those libraries bring some of the features that I'm talking here, but not all. And I would like to have also an environment independent library so that same library could be used with server side JavaScript . Best library so far that I've found is php.js, but I don't like how it is polluting the global namespace. I'm also not too fond of how PHP-functions are named.

• Rewriting usort function because of fatal error (PHP bug)

  - by Lionel

  The two following usort functions throw fatal error Base lambda function for closure not found in our productive environment (PHP 5.4). This seems to be a known PHP bug that should be fixed by now (https://bugs.php.net/bug.php?id=52144), but it still occurs for us. Anyway, we unfortunately don't have time to figure out what's wrong with our PHP configurations etc. We would like to rewrite these two functions without the use of anonymous functions, so that the error doesn't occur anymore. Ordering of a multidimensional array ($array) by value of key "position": usort($array, function($a, $b) { return $a['position'] - $b['position']; }); Ordering of a multidimensional array ($array) according to the order of a second array ($position_order): usort($array, function($a, $b) use($position_order) { return (isset($position_order[$a['ftid']]) ? ($position_order[$a['ftid']] - $position_order[$b['ftid']]) : 1); }); Especially the latter causes some headache, as we don't know how to pass the "outside" array $position_order.

  - by figuedmundo

  Well I googled my question but I couldn't find anything or I it's not the correct question..

Is it possible, and how I can do this ?? Thanks in advance and sorry for my english.

• fstream stopping math.h from working

  - by CaptainProg

  I am creating a program in C++ in which I need to read a text file in. I have included the fstream header file, which allows me to open the file, but having added the include, I now receive countless errors relating to math.h functions. Examples: 1>c:\program files\microsoft visual studio 10.0\vc\include\cmath(19): error C2061: syntax error : identifier 'acosf' 1>c:\program files\microsoft visual studio 10.0\vc\include\cmath(19): error C2059: syntax error : ';' Is there any way I can include the text file reading functions of fstream without compromising the math.h functions? And why does this conflict occur anyway? /Edit/ It seems the errors are in the cmath standard header file. It is nothing I have access to, but for the sake of completion, here is the code that is causing the errors: using _CSTD acosf; using _CSTD asinf; using _CSTD atanf; using _CSTD atan2f; using _CSTD ceilf; (etcetera)

• C++ function-pointer and inheritance

  - by pingvinus

  In parent class I have function, that operates under an array of functions, declared in child-class, number of functions for every child-class may vary. But since every function uses some object-variables, I can't declare them as static. I've try to do something like this: class A { public: typedef int (A::*func)(); func * fs; void f() { /*call functions from this->fs*/ } }; class B : public A { public: int smth; B(int smth) { this->smth = smth; this->fs = new func[1]; fs[0] = &B::f; } int f() { return smth + 1; } }; But, obviously it doesn't work. Any suggestions?

• Receiving SQL Server events from a CLR function

  - by Pablo Lerner

  I wrote a CLR class with several methods, which are linked as functions in a SQL Server 2005 database. When several of these functions are used in scope of one transaction or connection, I need another one to be automatically executed to clean up some stuff, at the time of transaction or connection close (either time is good for now, later I will decide which is best). I figure that receiving events from another new CLR functions can do, but I don't know how to achieve that. Can anyone point me to information on modules, documents or whatever, that can help me understand how to receive transaction or connection closing events in a CLR class, or how to execute a particular function when these events occur?

• PL/SQL exception and Java programs

  - by edwards

  Hi Business logic is coded in pl/sql packages procedures and functions. Java programs call pl/sql packages procedures and functions to do database work. pl/sql programs store exceptions into Oracle tables whenever an exception is raised. How would my java programs get the exceptions since the exception instead of being propagated from pl/sql to java is getting persisted to a oracle table and the procs/functions just return 1 or 0. Sorry folks i should have added this constraint much earlier and avoided this confusion. As with many legacy projects we don't have the freedom to modify the stored procedures.

• How can I resolve naming conflict in given precompiled libraries?

  - by asm

  I'm linking two different libraries that have functions with exactly same name (it's opengl32.lib and libgles_cm.lib - OpenGL ES emulation under Win32 platform), and I want to be able to specify, which version I'm calling. I'm porting a game to OpenGL ES, and what I want to achieve, is a split-screen rendering, where left side is an OpenGL version, and right side is a ES version. To produce the same result, they will recieve slightly different calls, and I'll be able to visually compare them, effectively finding visual artifacts. It worked perfectly with OpenGL/DirectX at the same window, but now the problem is that both versions imports the functions with the same name, like glDrawArrays, and only one version is imported. Unfortunately, I don't have sources of any of that libraries. Is there a way to... I dont' know, wrap one library into additional namespace before linking (with calls like ES::glDrawArrays), somehow rename some of functions or do anything else? I'm using microsoft compiler now, but if there will be solution with another one (GCC/ICC), I'll switch to it.

• When is C++ covariance the best solution?

  - by Neil Butterworth

  This question was asked here a few hours ago and made me realise that I have never actually used covariant return types in my own code. For those not sure what covariance is, it's allowing the return type of (typically) virtual functions to differ provided the types are part of the same inheritance hierarchy. For example: struct A { virtual ~A(); virtual A * f(); ... }; struct B : public A { virtual B * f(); ... }; The different return types of the two f() functions are said to be covariant. Older versions of C++ required the return types to be the same, so B would have to look like: struct B : public A { virtual A * f(); ... }; So, my question: Does anyone have a real-world example where covariant return types of virtual functions are required, or produce a superior solution to simply returning a base pointer or reference?

• wordpress path url in js script file

  - by Cam

  I added custom script wp_enqueue_script('functions', get_bloginfo('template_url') . '/js/functions.js', 'search', null, false); works great, except in the functions.js i have Reset.style.background = "url('../images/searchfield_clear.png') no-repeat top left"; now this used to work before, until changed to pretty permalinks and .htaccess the folder hierarchy is like: themename/js themename/images (the images and js folder are in themename folder) i tried ../images - ./image - /images normally it should go back 1 level where-ever the js file is located.... i dont want to use full path is there a other way that wordpress can recognize in the javascript file to have the correct path? currently i am just confused what i am doing wrong

• Haskell: Problems with overloading: Interpreter can´t tell which + to use

  - by Ben

  Hi, I want to make functions Double - Double an instance of the Num typeclass. I want to define the sum of two functions as sum of their images. So I wrote instance Num Function where f + g = (\ x - (f x) + (g x)) Here the compiler complains he can´t tell whether I´m using Prelude.+ or Module.+ in the lambda expression. So I imported Prelude qualified as P and wrote instance Num Function where f + g = (\ x - (f x) P.+ (g x)) This compiles just fine, but when I try to add two functions in GHCi the interpreter complains again he can´t tell whether I´m using Prelude.+ or Module.+. Is there any way I can solve this problem?

Can i just include inside a file i included? Or should i use require/include_once ? help me out thank you

• Python: Using `copyreg` to define reducers for types that already have reducers

  - by cool-RR

  (Keep in mind I'm working in Python 3, so a solution needs to work in Python 3.) I would like to use the copyreg module to teach Python how to pickle functions. When I tried to do it, the _Pickler object would still try to pickle functions using the save_global function. (Which doesn't work for unbound methods, and that's the motivation for doing this.) It seems like _Pickler first tries to look in its own dispatch for the type of the object that you want to pickle before looking in copyreg.dispatch_table. I'm not sure if this is intentional. Is there any way for me to tell Python to pickle functions with the reducer that I provide?

• Passing around objects to network packet handlers ?

  - by xeross

  Hey, I've been writing a networking server for a while now in C++ and have come to the stage to start looking for a way to properly and easily handle all packets. I am so far that I can figure out what kind of packet it is, but now I need to figure out how to get the needed data to the handler functions. I had the following in mind: Have a map of function pointers with the opcode as key and the function pointer as value Have all these functions have 2 arguments, packet and ObjectAccessor ObjectAccessor class contains various functions to fetch various items such as users and alike Perhaps pass the user's guid too so we can fetch it from the objectaccessor I'd like to know the various implementations others have come up with, so please comment on this idea and reply with your own implementations. Thanks, Xeross

• Unresolved External Symbol

  - by TomO

  I am working on wrapping a large number of .h and .lib files from native C++ to Managed C++ for eventual use as a referenced .dll in C#. I have the .lib files linked in and everything has been going smoothly so far. Upon wrapping the latest .h file, I hit a snag when 2 functions came back with the link error: error LNK2019: unresolved external symbol __imp__htonl@4 referenced in function "public: void __thiscall Field::setCharacter(unsigned char,int)" (?setCharacter@Field@@QAEXEH@Z) myutils.lib I have referenced "myutils.lib" in the linker options, so that shouldn't be the issue. What's strange is that I have about 20 functions in this particular .h file and all of the rest are linking just fine except for 3 functions. Any ideas?

• C++ allocate objects on heap of base class with protected constructors via inheritance

  - by KRao

  I have a class with protected constructor: class B { protected: B(){}; }; Now I derive from it and define two static functions and I manage to actually create objects of the class B, but not on the heap: class A : public B { public: static B createOnStack() {return B();} //static B* createOnHeap() {return new B;} //Compile time Error on VS2010 }; B b = A::createOnStack(); //This works on VS2010! The question is: 1) Is VS2010 wrong in allowing the first case? 2) Is it possible to create objects of B without modifying B in any way (no friendship and no extra functions). I am asking, because it is possible to make something similar when dealing with instances of B and its member functions, see: http://accu.org/index.php/journals/296 Thank you in advance for any suggestion! Kind regards

• Securely using exec with PHP to run ffmpeg

  - by Venkat D.

  I would like to run ffmpeg from PHP for video encoding purposes. I was thinking of using the exec or passthru commands. However, I have been warned that enabling these functions is a security risk. In the words of my support staff: The directive 'disable_functions' is used to disable any functions that allow the execution of system commands. This is for more security of the server. These PHP functions can be used to crack the server if not used properly. I'm guessing that if exec is enabled, then someone could (possibly) execute an arbitrary unix command. Does anyone know of a secure way to run ffmpeg from PHP? By the way, I'm on a dedicated server. Thanks ahead of time!

• Comments for Function in Emacs

  - by Ryan

  I'm looking for a way to add comments for my functions in Emacs. Of course doxymacs is a nice candidate. But I prefer another way works without the necessary libs. Can anyone recommend some others ways for adding smart comments for functions in Emacs? Thanks. Edit: Now I found this: http://nschum.de/src/emacs/doc-mode/, but it seems that it does not work well after I require it into my .emacs and add hook for js-mode. Doesn't it support js functions ?
