Module: TwirlRunner

Defined in:
lib/ruby-progress/cli/twirl_runner.rb

Overview

Top-level runtime helper module for the Twirl CLI.

Contains helper methods used by the ‘TwirlCLI` dispatcher. These methods implement the runtime behavior (running a command, running indefinitely, or launching in daemon mode) and were extracted to reduce module size and improve testability.
