output

Overview ¶

Package output demonstrates the app-wide output console: everything the app has said, kept, and readable long after the statusbar wiped it.

The problem it solves is visible from this screen. Pick "Deploy fails with a wrapped error" and watch the footer: you get one truncated line, and it is gone on the next keypress. The full %w chain never had anywhere to go. Press "o" and it is all still there.

Four things feed the console, and this screen exercises all of them:

• app.Info / app.Error — captured automatically, no code change needed.
• app.InfoDetail / app.ErrorDetail — summary to the bar, body to the log.
• app.ErrorOf — the %w chain, one wrap per line, without hand-formatting.
• runner.Capture — a subprocess whose stdout/stderr stream into the log while the TUI stays live. Start the 30-second one and keep navigating; the badge shows ⟳ while it runs, and "x" on the console kills it.

The console is opt-in: none of it exists unless app.Options.OutputKey is set. See examples/launcher/main.go, which sets it for the whole suite.

Note OnEnter: closing the console pops with app.OutputClosed, and a screen whose OnEnter starts a fetch has to say so, or glancing at a log silently refetches whatever was underneath.
