clojure source-code circular-dependency
I’m working on some Clojure code that has some circular dependencies between different namespaces and I’m trying to work out the best way of resolving them.Basic issue is that I get a “No such var: namepace/functionname” error in one of the files I tried to “declare” the function but then it complains with: “Can’t refer to a qualified var that doesn’t exist” I could of course refactor the entire codebase but that seems impractical to do every time you have a dependency to resolve….. and might

c# dependency-injection assemblies circular-dependency
Project#1 has some interfaces and classes that project#2 references.Now I want to use the implementation of Project#2 in Project#1 but vs.net complains about a circular dependency.If I was to use dependancy injection in Project#1 and bind to the implementation in Project#2 (since it adheres to the interface contract), will this work or I will still get the circular dependency error message at runtime?

This gives me headache…I have a project called ‘talktome’, with no runtime dependencies.Also I have project ‘talktome-tools’, which depends on ‘talktome’.No problems, until I realize that the unit-tests in ‘talktome’ depends on ‘talktome-tools’.What solutions are there?

c++ static include circular-dependency
In a project I have 2 classes:// mainw.h#include “IFr.h” … class mainw { public: static IFr ifr; static CSize=100; … };// IFr.h#include “mainw.h” … class IFr { public float[mainw::CSize]; };But I cannot compile this code, getting an error at the static IFr ifr; line. Is this kind of cross-inclusion prohibited?

In my project I have two libraries that would currently result in a circular dependency which I am unable to resolve.One library provides common data structures for the whole solution. This library contains a construct similar to this:namespace Common {public class Foo {//[Editor( typeof( UserEditor ), typeof( UITypeEditor ) )]public UInt32 OwnerId { get; set; }}public class User {public UInt32 Id { get; set; }} }Now in one of the projects in our solution, we would like to edit Foo instances thr

Python won’t allow me to import classes into eachother. I know there is no “package” solution in Python, so I’m not sure how this could be done. Take a look at my files’ codes:file Main.py:from Tile import tile tile.assign() class main:x = 0@staticmethoddef assign():tile.x = 20file Tile.py:from Main import main main.assign() class tile:x = 0@staticmethoddef assign():main.x = 20I get the error “class tile can not be imported”.

I’m gonna go C++ über n00b on this one and ask how is the best way to deal with a circular dependency when you have inheritance.The set is simple: Scene class extends Actor; Scene has a pointer to a vector of Actors; Actor has a pointer for (parent) Scene.As for include files I got:Scene.h:#include <string> #include <vector> using namespace std;#ifndef __Scene_h__ #define __Scene_h__#include “Actor.h”namespace myns {// class Actor;class Scene; }namespace myns {class Scene: public myn

I believe all four methods below will work, but it’s unclear to me why anyone would ever use the first three simply because it’s more code. However, the first (and most verbose) one is the one given in the RequireJS docs.define “circular1”, [“example1”], -> “circular1” define “circular2”, [“example2”], -> “circular2” define “circular3”, [“example3”], -> “circular3” define “circular4”, [“example4”], -> “circular4″#1 define “example1”, [“require”, “circular1”], (require, circular) ->

c++ compiler-errors circular-dependency
I have three classes: a TopClass which contains an instance of a BottomClass pointer. The BottomClass contains a pointer to a HelperClass. The HelperClass keeps a pointer to the TopClass. Circular dependency pops up and a forward declaration is needed in the HelperClass.All of this is illustrated with the following code snippets:#include “BottomLevel.h”namespace foo {class TopLevel{private:BottomLevel* item;}; }-#include “HelperClass.h”namespace foo {class BottomLevel{private:HelperClass* item;}

c++ compiler-errors circular-dependency
I often find myself in a situation where I am facing multiple compilation/linker errors in a C++ project due to some bad design decisions (made by someone else 🙂 ) which lead to circular dependencies between C++ classes in different header files (can happen also in the same file). But fortunately(?) this doesn’t happen often enough for me to remember the solution to this problem for the next time it happens again. So for the purposes of easy recall in the future I am going to post a representat

I’d like to get something like thisvar isChild = isInstanceOf( var1, ‘Constructor’)that should be equivalent tovar isChild = (var1 instanceof Constructor)The thing is I do not have the function Constructor available in scope, so I’d like to just pass a string.I guess I should traverse up the prototype chain in order to get the constructor.toString() and then compare it, but I don’t quite know how to achieve it.– I will complete a little bit the context, mainly because I found a better solutionI

I came across the following code in an articlestruct entire_program {struct B;struct A{B *bbb;void Aa() { B bb; bb.Bb(); };};struct B{A aaa;void Bb() { A aa; aa.Aa(); };}; };Why am I allowed to call method Bb() in this case, but if I change struct entire_program to namespace entire_program it generates a compiler error?I already read this question, what I am asking is: if it is possible to call methods that are undefined yet within classes/structs/unions why don’t namespaces work the same way

javascript scope variable-scope circular-dependency
I have a javascript app that I’m developing where I’m building an action tree on the fly and I’ve found myself in the curious situation of wanting to purposefully introduce a circular dependency. After an initial very hacky attempt, I discovered that JavaScript variable scoping actually introduces a a pretty reasonable way to solve this. I’m still no expert at JavaScript, so I wanted to get some input on best practices. Here is a snippet of working code:var Step = function(title, instructions, a

I’m setting up a nested categories structure in Backbone with RequireJS.In this structure, a categories collection contains category models, and a single category model can contain a categories collection. Unfortunately this seems to cause the dreaded circular dependencies problem in RequireJS. I have read the docs on RequireJS (http://requirejs.org/docs/api.html#circular) however I am finding the explanation with ‘a’ and ‘b’ confusing.Here is my code, which is causing the problem:define([“jqu

I have an object that contains circular references, and I would like to look at the JSON representation of it. For example, if I build this object:var myObject = {member:{}}; myObject.member.child = {}; myObject.member.child.parent = myObject.member;and try to callJSON.stringify(myObject);I get the error “too much recursion”, not surprisingly. The “child” object has a reference to its “parent” and the parent has a reference to its child. The JSON representation does not have to be perfectly accu

I had faced a circular dependency in my program and solved it with using pointers and forward declarations. I had made a file dn.hpp for this purpose. Everything was OK until I moved to shared pointers instead of generic. I created typedefs for shared pointers in dn.hpp. Everything works with generic pointers (commented out), bun not with shared.It returns an error: field ‘parentGraph’ has incomplete type node.h line 21(I am using mingw with boost 1.47)Please help me to resolve this issue.Here
