PyFlux language syntax

PyFlux: what is it?

PyFlux is a Flux specific language, which can be defined in the following manner:
PyFlux =

Python programming language +

Flux command language

PyFlux is therefore an overload of Python into which Flux commands are added.

PyFlux syntax

The PyFlux syntax is based:

Flux entities and PyFlux objects

PyFlux is an object-oriented programming language. There is a PyFlux type (class) corresponding to each Flux type-entity. The Flux entities are PyFlux objects (instances). The structure of the object is defined by fields called attributes, which possess a set of methods. The methods form the object interface.

A PyFlux type can have sub-types, which inherit the attributes and methods from their parent type. The sub-types are distinguished from their parent type by means of the supplementary attributes and methods.

Example: Point type

The structure of the Flux entity in the PyFlux language is presented in the example of the Point entity.
