libixion

Ixion is a general purpose formula parser & interpreter that can

calculate multiple named targets, or "cells". The goal of this project is to create a library for calculating the results of formula expressions stored in multiple named targets, or “cells”. The cells can be referenced from each other, and the library takes care of resolving their dependencies automatically upon calculation. The caller can run the calculation routine either in a single-threaded mode, or a multi-threaded mode. The library also supports re-calculations where the contents of one or more cells have been modified since the last calculation, and a partial calculation of only the affected cells need to be calculated. Supported features: - Each calculation session is defined in a plain text file, which is parsed and interpreted by the Ixion parser. - Fully threaded calculation. - Name resolution using A1-style references. - Support 2D cell references and named expressions. - Support range references. - Dependency tracking during both full calculation and partial re-calculation. - Inline strings. - Volatile functions. The framework for volatile functions is implemented. We just need to implement more functions.
