Using C++ Boost libraries for KDevelop

[Vladimir Prus]

Hi,
the more I work on debugger, the more I think that using some libraries from 
C++ Boost would simplify the code quite a bit.

For example, I send a command to debugger and want to be notified when that 
command finished. Currently, there's no such way, at all. All possible 
solutions are pretty clumsy.

With C++ Boost, specifically with Boost.Function and Boost.Bind libraries, 
things will be improved a lot, I'll be able to write this:

    class GDBController {
    public:
        void queueCmd(const QString& command, 
                      boost::function<void ()> callback);
    };

    class SomeOtherClass {
    public:
        void do_operation()
        {
                controller->queueCmd(
                   "whatever", 
   				boost::bind(&SomeOtherClass::step_2, this));
        }
        void step_2()
        {
			// Continue with the operation.
        }
    };

Here: 
- boost::function<void ()> is a generic functional object taking
  no arguments and returning nothing
- boost::bind in the above example takes method pointer, and this,
  and binds them together. The resulting class instance can be
  called with zero arguments.


The libraries in question are header-only -- they don't require any linking,
so this reduces problems somehow.

So, what is the general opinion about this:
- is it OK to add extra third party dependencies, in general
- any conditions the dependency must fulfill?
- it is best to rely on pre-installed dependency, or package it
  with KDevelop?
