SeExpr - An embeddable expression evaluation engine

Super impatient CMake building and installing guide

$ git clone
$ cd SeExpr
$ mkdir build
$ cd build
$ cmake ../
$ make doc      # optional make documentation
$ make install

You can try the test application asciiGraph which is a simple function grapher... e.g.

./asciiGraph "x^3-8*x"

Getting started

Examining the demo applications in src/demo is a great way to see some usage examples of the library. The basic strategy is to subclass the Expression class and implement the methods that describe what extra functions and variables your expression evaluation will need

Be sure to check out the doxygen pages for an API overview: (for older documentation)
