SimpleQueryParserSpirit

A simple query parser written in Boost.Spirit

Introduction

This is a simple query parser written in Boost.Spirit. It can recognizes simple queries like:

this AND that
this AND not that
this OR that
NOT (this AND that)

Compile

You need boost.spirit to compile this project.

$ mkdir build
$ cd build
$ cmake ..
$ make

P.S.

This is a toy project. I tried three methods to build a query parser. You can find the other two:

SimpleQueryParser : A simple query parser generated by flex and bison (C Language)
SimpleQueryParserPlusPlus : A simple thread-safe query parser generated by flex and bison (C++ Language)

After I completed these three projects, my conclusions about Flex/Bison vs Boost.Spirit are as follows:

There are many documentations about Flex/Bison, but few of them talk about thread-safty or generating a C++ parser.
Boost.Spirit is harder to learn. The documentation is poor. The code is hard to debug and takes much more time to compile.
