Overview

This module contains helper methods that are used by formatters that print output to the terminal.

FORMAT is a hash of Proc objects, keyed by step-definition types, e.g. “FORMAT”. The Proc is called for each line of the step’s output.

format_step calls format_string, format_string calls format_for to obtain the formatting Proc.

Example:

The ANSI color console formatter defines a map of step-type to output color (e.g. “passed” to “green”), then builds methods named for the step-types (e.g. “def passed”), which themselves wrap the corresponding color-named methods provided by Term::ANSIColor (e.g. “def red”).

During output, each line is processed by passing it to the formatter Proc which returns the formatted (e.g. colored) string.
