Boost

I took the plunge. One word - 'Wow!'. What a fantastic library! Can anyone give me some quick Boost recommendations? So far I have used list_of(), indirect_iterator, tokenizer, trim and, of course, shared_ptr. What are your favourite Boost libs?

Robert Edward Caldecott wrote: 'Wow!'. What a fantastic library! Agree 100%. Robert Edward Caldecott wrote: Can anyone give me some quick Boost recommendations? It really depends on the nature of your projects. I am currently involved with text processing libraries, and thus mostly use regex, lexical_cast and tokanizer, and looking forward to using string_algo. Also, I make a heavy use of smart pointers, tuple and test, and to a lesser extent filesystem, bind and graph.

I'm also a Boost addict... ;) You should definitely take a look at boost::bind and boost::signal, I use them all the time. I recently started using boost::serialization and boost::regex. Both are simple to use and extremely powerful.

Practically: regex, bind (oh, yeah!), shared_ptr, string_algo, signals, function, tuple, variant, optional From a 'wow' point of view: lambda, spirit. I've also started using Boost.Test for unit testing - :cool: Just one thing - if you're not using VC7.1, try and do so - you'll be doing yourself a favour...

Yeh, bind. Very useful. I have been using containers of shared_ptr's, and it is so cool that I can do something like:
class CFoo
{
...
void fn(int n, std::string str)
{
// Do something
}
};...
std::vector<boost::shared_ptr<CFoo> > v;
v.push_back(boost::shared_ptr<CFoo>(new CFoo));
...
for_each(v.begin(), v.end(), boost::bind(&CFoo::fn, _1, 1234, "Boost!"));Splendid. Using boost::bind for std::find_if is also very useful. So much to learn...

Boost.MPL[^] is an impressive achievement and a mind-opener for those venturing into the world of C++ metaprogramming. I wonder, however, how much real use metaprogramming gets in the C++ community.

Here[^] is a very interesting example of use of Boost MPL.

You don't think smart pointers are useful? You don't think for_each is useful? Aaahh ... I see from previous posts that you actually think STL is "bloatware". What a shame. Other than the fact that both STL and Boost are incredibly powerful, I need to write code for Windows AND Linux, and without these libraries, this would be difficuly to achieve.

I think, somebody who puts pointers or smart pointers into a std container has not understood one basic principle of STL, that is, 'value semantics'. What a shame. Other than the fact that both STL and Boost are incredibly powerful, I need to write code for Windows AND Linux, and without these libraries, this would be difficuly to achieve. It's ok if it works for you. IMO, it's not really elegant that one has to write
v.push_back(boost::shared_ptr(new CFoo));
to insert an element.

typedef boost::shared_ptr<CFoo> foo_sp;
...
v.push_back(foo_sp(new CFoo));Elegant enough IMO, though people seem to either love or hate typedef. Using smart pointers in containers is very useful, and from experience, it has meant more time concentrating on the job at hand instead of tracking down memory leaks. I did use the ATL7 CAutoPtr class (and associated CAtlArray/CAtlList) but that's no help for writing portable code plus I prefer using STL iterators over MFC's 'POSITION' scheme. Shrug. Whatever works I guess. But the more I use STL/Boost, the more I wonder why I went so long without it! :-)

Is Boost a full STL implementation? If so, won't some of the classes clash with VC++'s STL classes? Or are the Boost classes in a different namespace?

No - it's not an STL implementation at all...apart from some of the things that are added at TR1 (like regex, smart pointers, function and some other stuff) and are so are not yet in any STL that you'll have access to). Really, if you consider Boost as a sandpit for libraries that are or could be potential additions to the Standard C++ library, you're not far wrong. Also - Boost classes are all in the boost namespace or a child namespace of boost.
