Request to know about "dynamic expression evaluation"
Hi, I would like to perform the dynamic expression evaluation in my c++ application. The dynamic expressions are like the SQL queries. Since the expressions could be nested & hence the parsing & evaluation of such expressions is reducing the performance of my application. May I please know, whether BOOST provides a support for such dynamic expression evaluation in C++? Please guide. Thanks in advance for the guidance.

Look for "expression templates"
Boost.Proto provides support for expression templates. Expression templates are only suitable for statically-parsable expressions (which may be dynamically evaluated). I am not sure whether the expression syntax is static or dynamic in the Ganesh's case. If it's dynamic, Ganesh should look at Boost.Spirit or Boost.Xpressive. -- Dave Abrahams Boost Consulting http://www.boost-consulting.com
