📝 Walkthrough

Walkthrough

The TUI now auto-advances pending exercises after successful checks. It displays a countdown, removes standalone # I AM NOT DONE markers, saves the cleaned text, and reruns the exercise. Editing or changing state cancels the operation.

Changes

Exercise auto-advance

Layer / File(s) Summary
Marker removal and editor update
pythonlings/core/exercise.py, pythonlings/widgets/editor_pane.py, tests/unit/test_exercise.py
Exercise.strip_marker removes standalone markers while preserving other text. EditorPane.set_text updates content without moving the cursor. Unit tests cover both methods' behavior.
Countdown result presentation
pythonlings/widgets/output_panel.py, tests/tui/test_output_panel.py
OutputPanel displays pending success with an optional countdown and updates the remaining seconds. UI tests cover the countdown and marker-removal message.
Validated auto-advance flow
pythonlings/screens/track.py, pythonlings/screens/welcome.py, tests/tui/test_app_pilot.py
TrackScreen schedules, updates, cancels, and validates the auto-advance timer. It removes the marker, saves the editor text, and reruns the exercise. Onboarding text and TUI tests describe and verify the flow.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🟡 Moderate · up to ef970

Auto-submit may advance or alter an exercise based on stale results after the learner edits their code, and marker text inside a string can leave the exercise stuck. The PR should not merge until these cases are handled.

A bunny sees the green checks glow,
The marker hops away below.
Five seconds tick, then off we go,
Clean code saved in tidy flow.
Next lesson waits—ears held high!

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Schedule auto-advance only for the checked, removable marker snapshot.

The worker result applies to the text written before _run_current. Line 226 instead captures the current editor text. If the learner edits before the worker callback runs, a prior successful result can remove the marker from unverified learner text.

The same predicate uses Exercise.is_pending(). That method accepts marker text inside a string, but Exercise.strip_marker() returns that text unchanged. The countdown then ends without completion or a restored prompt.

Carry the submitted editor text through the worker callback. Schedule auto-advance only if the editor still equals that submitted text and strip_marker(submitted_text) != submitted_text. Add regression tests for an edit during an in-flight successful check and for marker text inside a string.

As per coding guidelines, preserve learner-edited exercises during workspace updates.
