All code in teeworlds should match this code guidelines.

Brackets and Such

Hardtabs, tabsize 4.

Use Allman style brackets like this:

if(MyInt != 5)
{
    while(MyInt)
    {
        MyFunction(&MyInt);
    }
}
ContinueMyStuff();

Comments

Use // style comments for most things. Larger blocks of comments can use /* */ style but shouldn't be used inside function bodies.

Identifiers

Use CamelCase with upper case on the first letter as well.

Variable Prefixes

m_

Class member

g_

Global variable

s_

Static variable

_p

Pointer

_a

Fixed array

Combine them appropriately.

Class Prefixes

C

Class, CMyClass, This goes for structures as well.

I

Interface, IMyClass

Null pointers

Use 0 or 0x0 instead of NULL. Because Teeworlds uses C++03, nullptr does not work either.

Passing Variables

Pass by value for smaller things, const reference for larger objects. By pointer if the function needs to modify the object. Don't cast values as just a reference. If the function needs to modify it, use a pointer to show it as well.

void MyFunction(int MyVar);
void MyFunction(const CMyClass &MyVar);
void MyFunction(int *pMyVar);

void MyFunction(int &pMyVar); // Never do this!

Examples

class IMyInterface
{
public:
    virtual void MyFunction(int InputVar) = 0;
};

class CMyImplementation : public IMyInterface
{
    static int ms_StaticCounter;
    int m_aSomeData[16];
public:
    void *m_pMyData;

    virtual void MyFunction(int InputVar)
    {
        // ...
    }
};
