  • How to prevent swallowing exceptions caused by unset expectations for a mocked object?

    - by Schultz9999
    I am looking for a way to modify catch block depending on if it's executed during the unit test run or not. The purpose is basically to detect/setup mock expectations which are swallowed because catch doesn't rethrow. I am using MSTest. One obvious thing is using preprocessor but I don't think it works. Especially if to use DEBUG define. There should be an easy way to detect that, shouldn't it? I must have been looking for something wrong because I couldn't find much info on that. try {...} catch(Exception) { Log(...); #if DEBUG throw; #endif }

  • bitfield mask calculation macro

    - by Aidan Cully
    We have a set of C macros, here, for using the preprocessor to do bitfield operations, and we run into warnings when attempting to use these macros in visual studio. The problem can be demonstrated very easily: #define BITFIELD_WIDTHMASK(Width) \ ((Width) >= 32 ? ~0x0ul : (1ul << (Width)) - 1) unsigned long foo(void) { return BITFIELD_WIDTHMASK(32); } Compiling this with MSVC yields the warning: test.c(12) : warning C4293: '<<' : shift count negative or too big, undefined behavior This isn't a behavior problem - the << operator won't be used in this case, and that should be detected at compile time. But does anyone have any suggestions about how to rewrite the macro to avoid the warning? Or, failing that, how to redesign the macro interface for this? Thanks in advance

  • How to reliably specialize template with intptr_t in 32 and 64 bit environments?

    - by vava
    I have a template I want to specialize with two int types, one of them plain old int and another one is intptr_t. On 64 bit platform they have different sizes and I can do that with ease but on 32 bit both types are the same and compiler throws an error about redefinition. What can I do to fix it except for disabling one of definitions off with preprocessor? Some code as an example: template<typename T> type * convert(); template<> type * convert<int>() { return getProperIntType(sizeof(int)); } template<> type * convert<intptr_t>() { return getProperIntType(sizeof(intptr_t)); } //this template can be specialized with non-integral types as well, // so I can't just use sizeof() as template parameter. template<> type * convert<void>() { return getProperVoidType(); }

  • How Iostream file is located in computer by c++ code during execution

    - by user3702024
    i want to know that in a c++ code during execution how iostream file is founded. we write #include in c++ program and i know about #include which is a preprocessor directive to load files and is a file name but i don't know that how that file is located. i have some questions in my mind... Is Standard library present in compiler which we are using? Is that file is present in standard library or in our computer? Can we give directory path to locate the file through c++ code if yes then how?

  • How can I write faster JavaScript?

    - by a paid nerd
    I'm writing an HTML5 canvas visualization. According to the Chrome Developer Tools profiler, 90% of the work is being done in (program), which I assume is the V8 interpreter at work calling functions and switching contexts and whatnot. Other than logic optimizations (e.g., only redrawing parts of the visualization that have changed), what can I do to optimize the CPU usage of my JavaScript? I'm willing to sacrifice some amount of readability and extensibility for performance. Is there a big list I'm missing because my Google skills suck? I have some ideas but I'm not sure if they're worth it: Limit function calls When possible, use arrays instead of objects and properties Use variables for math operation results as much as possible Cache common math operations such as Math.PI / 180 Use sin and cos approximation functions instead of Math.sin() and Math.cos() Reuse objects when passing around data instead of creating new ones Replace Math.abs() with ~~ Study jsperf.com until my eyes bleed Use a preprocessor on my JavaScript to do some of the above operations

  • Listing C/C++ functions (Code analysis in Unix)

    - by Jond
    Whether we're maintaining unfamiliar code or checking out the implementation details of an Apache module it can help if we can quickly traverse the code and build up an overview of what we're looking at. Grep serves most of my daily needs but there are some cases where it just wont do. Here's a common example of how it can help. To find the definition of a PHP function I'm interested in I can type this at the command line: grep -r "function myfunc" . This could be adapted very quickly to C or C++ if we know the return type, but things become more complicated if, say, I want to list every method that my class provides: grep "function " ./src/mine.class.php Since there's no single keyword that denotes a function or method in C++ and because it's generally more complex syntax, I think I'd need some kind of static code analysis tool, smart use of the C Preprocessor or blind faith the coder followed strict code guidelines (# of whitespace, position of curlies etc) to get these sorts of results. What would you recommend? p.s. be nice, this is my first post ;-) :p

  • How would one call std::forward on all arguments in a variadic function?

    - by Noah Roberts
    I was just writing a generic object factory and using the boost preprocessor meta-library to make a variadic template (using 2010 and it doesn't support them). My function uses rval references and std::forward to do perfect forwarding and it got me thinking...when C++0X comes out and I had a standard compiler I would do this with real variadic templates. How though, would I call std::forward on the arguments? template < typename ... Params void f(Params ... params) // how do I say these are rvalue reference? { y(std::forward(...params)); //? - I doubt this would work. } Only way I can think of would require manual unpacking of ...params and I'm not quite there yet either. Is there a quicker syntax that would work?

  • Xcode OpenGL Build Error (header file not found)

    - by Strix Nebulosa
    When building my Objective-C project (for Mac OS 10.9, Xcode 5.11), I get the error message Lexical or Preprocessor Issue 'OpenGL/OpenGL.h' file not found. The error is caused by the include section of the file CVDisplayLink.h where the above named file is included. CVDisplayLink.h belongs to the framework CoreVideo. Now there are two strange points related to that issue: The error appeared after I tried to test some basic OpenGL features using the tutorial in the Mac Developer Library ( https://developer.apple.com/library/mac/documentation/GraphicsImaging/Conceptual/OpenGL-MacProgGuide/opengl_drawing/opengl_drawing.html#//apple_ref/doc/uid/TP40001987-CH404-SW8 ). I added an NSOpenGLView to my MainMenu as well as the related code given in the tutorial. Then the error message appeared. I also tried to add the OpenGL and CoreVideo frameworks to my project target, but this did not help. After some frustration, I removed the NSOpenGLView from my project, as well as all related code. Now the error Message still appeares and I have no Idea how to ged rid of it.

  • How to leave out some System.out/logging statements while executing java code?

    - by iamrohitbanga
    In C++ if we do not want some statements to compile into code that ships like assert function calls, we control their compilation through #ifndef preprocessor directives. How do we do this in Java? I have some System.out.println() statements for debugging which I would like to remove for the final code. one way is to make them execute conditionally under the affect of a boolean variable. Is there a better way of doing this? As I have a java swing application I can turn off the System.out.println statements without affecting the output. What is the method of doing this?

  • Substitute all matches with values in Ruby regular expression

    - by Lewisham
    Hi all, I'm having a problem with getting a Ruby string substitution going. I'm writing a preprocessor for a limited language that I'm using, that doesn't natively support arrays, so I'm hacking in my own. I have a line: x[0] = x[1] & x[1] = x[2] I want to replace each instance with a reformatted version: x__0 = x__1 & x__1 = x__2 The line may include square brackets elsewhere. I've got a regex that will match the array use: array_usage = /(\w+)\[(\d+)\]/ but I can't figure out the Ruby construct to replace each instance one by one. I can't use .gsub() because that will match every instance on the line, and replace every array declaration with whatever the first one was. .scan() complains that the string is being modified if you try and use scan with a .sub()! inside a block. Any ideas would be appreciated!

  • Changing the value of a macro at run time

    - by BrandiNo
    I'm working in Visual Studio 2010, using C++ code. What I'm trying to do is change the value of a preprocessor directive during run time, not sure if it's possible but i've tried this.. somefile.h static int mValue = 0; #define POO = mValue; ... #if POO 0 //define class methods #else //define class methods differently } main.cpp main() { //Code calls constructor and methods allowed when POO is 0 //Code increments mValue //Code calls constructor and methods allowed when POO is 1 } How can POO be changed so that class objects uses a different implementation of other methods? Or if it's not possible, what's a another approach to this?

  • A taxonomy of web frameworks?

    - by Rob
    There seem to be several different categories of web frameworks, e.g. MVC, component based, event-driven, action-based, etc. I can't find a comprehensive list of categories and definitions anywhere. (I dare not ask for examples as well.) Is there a general taxonomy of web application frameworks somewhere, or is this too fuzzy a question to allow for definitive answers?

  • Logging in with webrat, celerity doesn't recognize that.

    - by Matthew Willhite
    I'm using cucumber with webrat, and I am just starting to integrate culerity/celerity. My webrat login steps have been working great, and I have them as a Background for many of my scenarios. The problem is that although I can log in successfully via webrat, my celerity specific step definitions don't seem to recognize that. I can check the session from the step def and it confirms that I have a valid user that is logged in. Any advice would be greatly appreciated! Thanks

  • Code Generation(based on templates) for COCOA

    Hi, I have written a library for I-phone which is based upon some object models(whose definitions I get via XML). Now I have one implementation for a sample model ready but to make the code library generic I want to write an application where I can templatize the code and provide placeholders for data model specific points. Is there any tool available for Xcode to enable me do this. In java "Velocity" does this job for me. Regards, Vikas
