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

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]

Branch: CURRENT, Version: 0.19.0nb2, Package name: py312-libixion-0.19.0nb2, Maintainer: pkgsrc-users

Python bindings for Ixion.

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.

libixion, py-libixion: Update to 0.18.1

Changelog:
0.81.1
* fixed a 32-bit Linux build issue as discovered on Debian, due to
  a clash on two 32-bit unsigned integer types being used with std::variant.

0.18.0
C++ API
* removed the formula_model_access interface from model_context, and
  switched to using model_context directly everywhere.
* revised formula_tokens_t type to remove use of std::unique_ptr for each
  formula_token instance. This should improve memory locality when iterating
  through an array of formula token values. A similar change has also been
  made to lexer_tokens_t and lexer_token types.

formula interpreter
* added the following 41 built-in functions:
    ABS
    AND
    COLUMN
    COLUMNS
    COUNT
    COUNTBLANK
    EXACT
    FALSE
    FIND
