class Ven::Master

Overview

An abstraction over an implicit collection of Inputs.

Implements Ven module system (e.g., distinct and expose).

Note that all files in the current directory (CD), as well as the files of #homes, are made into Inputs. But only those that were exposed are compiled and executed.

master = Master.new
master.load("a", "x = 1 + 1")
master.load("b", "y = 2 + x")
master.load("c", "say(x, y)") # STDOUT: 2 \n 4
