./math/libixion, General purpose formula parser & interpreter

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ]

Branch: CURRENT, Version: 0.20.0nb3, Package name: libixion-0.20.0nb3, Maintainer: pkgsrc-users

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.

math/libixion,math/py-libixion: Update to 0.20.0

Changelog:
ixion 0.20.0
* C++ API
  * changed the return type of model_context::get_sheet_name() to
    std::string_view.  It was previously std::string.
  * ixion::celltype_t has been renamed to ixion::cell_t.
* formula interpreter
  * added support for using an error token as an assignable value.  With this
    change, you can use an expression such as '=#REF!'.
  * ISERR function is now implemented as a built-in function.
* misc
  * enabled building of Python module on Windows via CMake, but it is not
    installed as part of the install target.
  * switched to mdds 3.0 and adjusted all uses of mdds::sorted_string_map to its
    new API.
  * parsing of error values is more
