3. Data Flow¶
Depending on the scripting interface, directing the flow can be represented by plain text or interconnected lines
3.1. Text-based Symbols¶
The text-based scripting language aims to combine the quick and intuitive feel of shell scripting. Adopting a Unix Pipeline-like syntax.
3.1.1. | as Synchronous Forward¶
This operator pushs data to next operation and do block/wait for it finish. For example:
[1,2,3,4] | print
Will always print (each item in it’s own thread and in this order): 1, 2, 3, 4.
3.1.2. -> as Asynchronous Forward¶
This operator pushs data to the next operation and do not block/wait for it to finish. For example:
[1,2,3,4] -> print
May print (each item in it’s own thread): 4, 3, 2, 1 or 2, 1, 3, 4 or even 1, 2, 3, 4.
3.2. “Boxes and Arrows”¶
Currently, in the Visual Programming Language, all lines are treated as asynchronous forward.
