Enhancements#

This release introduces the Macro feature, which enables users to define and store Python functions as part of a model. Macros are simple Python functions that can be used for running and manipulating the model itself. Macros are saved and loaded with the model, making it easier to package related code alongside model definitions.

  • Add Macro class for representing Python functions stored within models (GH206).

  • Add defmacro() decorator for defining macros directly within model code (GH206).

  • Add new_macro() method for programmatically creating macros in models (GH206).

  • Add macros property to access all macros defined in a model (GH206).
