Most used parts of Boost [closed]

Answer 1

We found boost::spirit pretty useful for a business solution to parse ECMAScript. Complex, but very nice!

Answer 2

boost::shared_ptr is a requirement for modern C++ programming IMHO. That's why they added it to the standard with TR1. boost::program_options, boost::bind, and boost::signal are really nice if you know what they are for and how to use them. The last two tend to scare newcomers though.

Answer 3

I'm surprised to don't see yet between the answers Boost.Thread.

Answer 4

Nobody has mentioned Multi-Index Containers so I'll chime in late. It's not that often that you need them, but without boost it is a real pain to create an equivalent data structure, as well as being less efficient. I've been using them a lot recently to create containers that have look up on 2 keys.

Answer 5

BOOST_STATIC_ASSERT

Update (October 2011): C++11 (C++0x) has static_assert http://www2.research.att.com/~bs/C++0xFAQ.html#static_assert

Answer 6

I use boost::numeric::ublas::matrix quite a bit.
