Overview

BaseFormatter provides common formatting methods for parameters, values, and timing. Subclasses must implement the colorize method for their specific output format.

Direct Known Subclasses

AnsiFormatter, XmlFormatter

Constant Summary collapse

DEPTH_COLORS =

Color codes for different depth levels in the call tree

[:green, :blue, :yellow, :magenta, :cyan, :red].freeze
