Where does a piped terminal get handled in the progress bar?

[winterqt]

ReporterStderr's documentation points out that not all terminals will be PTYs:

nextest/nextest-runner/src/reporter/imp.rs

Lines 22 to 26 in e1578c7

	pub enum ReporterStderr<'a> {
	/// Produce output on the (possibly piped) terminal.
	///
	/// If the terminal isn't piped, produce output to a progress bar.
	Terminal,

However, in the displayer, the bar is only disabled if an option (and/or two) is passed, or if Nextest detects that it's running in CI -- else, it'll show the progress bar:

nextest/nextest-runner/src/reporter/displayer/imp.rs

Lines 75 to 98 in e1578c7

	ReporterStderr::Terminal if self.no_capture => {
	// Do not use a progress bar if --no-capture is passed in. This is required since we
	// pass down stderr to the child process.
	//
	// In the future, we could potentially switch to using a pty, in which case we could
	// still potentially use the progress bar as a status bar. However, that brings
	// about its own complications: what if a test's output doesn't include a newline?
	// We might have to use a curses-like UI which would be a lot of work for not much
	// gain.
	ReporterStderrImpl::TerminalWithoutBar
	}
	ReporterStderr::Terminal if is_ci::uncached() => {
	// Some CI environments appear to pretend to be a terminal. Disable the progress bar
	// in these environments.
	ReporterStderrImpl::TerminalWithoutBar
	}
	ReporterStderr::Terminal if self.hide_progress_bar => {
	ReporterStderrImpl::TerminalWithoutBar
	}
	ReporterStderr::Terminal => {
	let state = ProgressBarState::new(self.test_count, theme_characters.progress_chars);
	ReporterStderrImpl::TerminalWithBar { state }
	}

Am I missing where the piped case is handled in ReporterStderrImpl::TerminalWithBar, or is this a regression?

Thanks for the question. This is actually handled within the progress bar library we use, indicatif. I've added a comment at bbf84b3.

Are you seeing an issue in practice related to this?

Closing since this has been answered.
