Overview

Lightweight command-line front-end. Read-only subcommands consume JSONFormatter output, which the bundled HTMLFormatter already drops alongside the HTML, so no runtime hooking is needed for those. Default paths follow the project's .simplecov coverage_dir setting when one is present.

def color_enabled?(opts, stream)
  return false if opts[:no_color]

  Color.enabled?(stream)
end

#coverage_dir ⇒ Object

Resolved once per process, by walking up from cwd for a .simplecov and loading it with SimpleCov.start neutered so it can't trigger tracking just because we asked it for a config value.

#dispatch(handler, command, rest, stdout:, stderr:) ⇒ Object

One rescue covers every subcommand's OptionParser, so a typo'd flag becomes a one-line error and exit status 1 instead of a backtrace.
