KCalCore

KCalCore is a C++ library that provides a framework for applications to handle and convert caloric and nutritional values. It is part of the KDE Extragear project, which offers supplementary applications and libraries for the KDE Plasma desktop environment. The primary purpose of KCalCore is to offer a standardized way to represent and calculate nutritional information, such as calories, proteins, fats, and carbohydrates, across different applications.

The library defines core data types and algorithms for managing nutritional data. This includes units of measurement and common conversions. Applications that integrate KCalCore can leverage its functionality to display nutritional information accurately, perform calculations for recipes or meal plans, and ensure consistency in how this data is handled. This promotes interoperability between different KDE applications that deal with dietary information, such as personal information managers or health-tracking tools. KCalCore aims to simplify the development process for such features by providing a robust and well-tested foundation.
