==Qu'est-ce que KDevelop?== 


[http://www.KDevelop.org KDevelop] est environnement de développement intégré (EDI) moderne pour le C++ (et d'autres languages) qui est l'une des nombreuses [http://www.kde.org/applications/ applications KDE]. Ainsi, il fonctionne sur Linux(même si vous utilisez un autre bureau, tel que GNOME) mais il est aussi disponible sur la plupart des autres variantes Unix et sur Windows.


'''KDevelop''' offrent toutes les commodités des EDI modernes. Pour les projets larges et les applications, sa fonctionnalité la plus importante est que '''KDevelop''' ''comprend le C++'': il parse l'intégralité des sources et retient quelles classes ont quelles fonctions membres, où les variables sont définies, quels sont leurs types, et plein d'autre chose sur votre code. Par exemple, imaginons qu'un des fichiers d'en-tête de votre projet declare une classe


{{Input|<syntaxhighlight lang="cpp">
class Car {
  // ...
  public:
    std::string get_color () const;
};
</syntaxhighlight>}}


et que plus loin dans votre programme vous avez


{{Input|<syntaxhighlight lang="cpp">
Car my_ride;
// ...do something with this variable...
std::string color = my_ride.ge
</syntaxhighlight>}}


it will have remembered that <code>my_ride</code> in the last line is a variable of type <code>Car</code> and offer you to complete <code>ge</code> as <code>get_color()</code> since this is the only member function of the <code>Car</code> class that starts like this. Instead of continuing to type you just hit <keycap>Enter</keycap> to get the full word; this saves typing, avoids typos, and doesn't require you to remember the exact names of the hundreds or thousands of functions and classes that make up large projects. 


As a second example, assume you have code like this:


<!--}}-->{{Input|<syntaxhighlight lang="cpp">
double foo ()
{
  double var = my_func();
  return var * var;
}


double bar ()
{
  double var = my_func();
  return var * var * var;
}
</syntaxhighlight>}}<!--{{-->


If you hover the mouse over the symbol <code>var</code> in function <code>bar</code> you get the option to see all uses of this symbol. Clicking on it will only show you the uses of this variable in function <code>bar</code> because '''KDevelop''' understands that the variable <code>var</code> in function <code>foo</code> has nothing to do with it. Similarly, right clicking on the variable name allows you to rename the variable; doing so will only touch the variable in <code>bar</code> but not the one with the same name in <code>foo</code>.


But '''KDevelop''' is not just an intelligent code editor; there are other things '''KDevelop''' does well. Obviously, it highlights the source code in different colors; it has a customizable indenter; it has an integrated interface to the GNU debugger '''gdb'''; it can show you the documentation for a function if you hover the mouse over a use of this function; it can deal with different kinds of build environments and compilers (e.g. with '''make''' and '''cmake'''-based project), and many other neat things that are discussed in this manual.
