  • How can I add imports to an "eval"ed piece of clojure code?

    - by Zubair
    I would like to evaluate some clojure code entered by users interactively, and I would like to "use" certain namespaces and "import" certain Java classes as well. I end up running the code using: (defn execute-command [string-command] let [ code-with-context (add-code-context string-command) result (eval(read-string code-with-context)) ] result ) My question is how can I program "add-code-context" to add the required context to the code in "string-command"?

  • What is wrong with this list comprehension code?

    - by suresh
    My aim is to list all elements of the array a whose values are greater than their index positions. I wrote a Haskell code like this. [a|i<-[0..2],a<-[1..3],a!!i>i] When tested on ghci prelude prompt, I get the following error message which I am unable to understand. No instance for (Num [a]) arising from the literal 3 at <interactive>:1:20 Possible fix: add an instance declaration for (Num [a])

    - by Spanky
    Hi, How do you set the image for a UIButton in code? I have this: UIButton *btnTwo = [UIButton buttonWithType:UIButtonTypeRoundedRect]; btnTwo.frame = CGRectMake(40, 140, 240, 30); [btnTwo setTitle:@"vc2:v1" forState:UIControlStateNormal]; [btnTwo addTarget:self action:@selector(goToOne) forControlEvents:UIControlEventTouchUpInside]; [self.view addSubview:btnTwo]; but don't see what will set the image for it. Any help appreciated, Thanks // :)

  • Better way to write an object generator for an RAII template class?

    - by Dan
    I would like to write an object generator for a templated RAII class -- basically a function template to construct an object using type deduction of parameters so the types don't have to be specified explicitly. The problem I foresee is that the helper function that takes care of type deduction for me is going to return the object by value, which will result in a premature call to the RAII destructor when the copy is made. Perhaps C++0x move semantics could help but that's not an option for me. Anyone seen this problem before and have a good solution? This is what I have: template<typename T, typename U, typename V> class FooAdder { private: typedef OtherThing<T, U, V> Thing; Thing &thing_; int a_; // many other members public: FooAdder(Thing &thing, int a); ~FooAdder(); void foo(T t, U u); void bar(V v); }; The gist is that OtherThing has a horrible interface, and FooAdder is supposed to make it easier to use. The intended use is roughly like this: FooAdder(myThing, 2) .foo(3, 4) .foo(5, 6) .bar(7) .foo(8, 9); The FooAdder constructor initializes some internal data structures. The foo and bar methods populate those data structures. The ~FooAdder dtor wraps things up and calls a method on thing_, taking care of all the nastiness. That would work fine if FooAdder wasn't a template. But since it is, I would need to put the types in, more like this: FooAdder<Abc, Def, Ghi>(myThing, 2) ... That's annoying, because the types can be inferred based on myThing. So I would prefer to create a templated object generator, similar to std::make_pair, that will do the type deduction for me. Something like this: template<typename T, typename U, typename V> FooAdder<T, U, V> AddFoo(Thing &thing, int a) { return FooAdder<T, U, V>(thing, a); } That seems problematic: because it returns by value, the stack temporary object will be destructed, which will cause the RAII dtor to run prematurely. One thought I had was to give FooAdder a copy ctor with move semantics, kinda like std::auto_ptr. But I would like to do this without dynamic memory allocation, so I thought the copy ctor could set a flag within FooAdder indicating the dtor shouldn't do the wrap-up. Like this: FooAdder(FooAdder &rhs) // Note: rhs is not const : thing_(rhs.thing_) , a_(rhs.a_) , // etc... lots of other members, annoying. , moved(false) { rhs.moved = true; } ~FooAdder() { if (!moved) { // do whatever it would have done } } Seems clunky. Anyone got a better way?

  • OpenGL code to render ribbon diagrams for protein

    - by eipxen
    Hey all, I am looking to render ribbon diagrams of proteins using OpenGL and C++. Does anyone know if any open source code for this already exists, or if there are good guides to do this? If not, I'd prefer to figure it out myself ;) but I didn't want to reinvent the wheel, especially if the wheel was free.

  • String replace for personalize code generator

    - by Xurxof
    I must do a automatic codes generator with user-configurable string with predefined keys and can not find a good way to do it. For example, a string OT-{CustomCode}-{Date}-{##} could generate codes OT-C0001-20100420-01 OT-C0001-20100420-02 I thought of using RegExpr.Replace(), but I would have problems if the code of a customer was {##} Any help is welcome! (and sorry for my english)
