Please, check our [contributing guide](../CONTRIBUTING.md) and talk to the core team before making major changes. Description of your pull request goes here. **Provide examples and/or screenshots** if your changes affect the user experience. --> Add ansi codes to move cursor position: `ansi cursor_left`, `ansi cursor_right`, `ansi cursor_up`, `ansi cursor_down` Why I add these? I'm trying to add a spinner to the message end for a long running task, just to find that I need to move the cursor left to make it work as expected: `with-progress 'Waiting for the task to finish' { sleep 10sec }` ```nu def with-progress [ message: string, # Message to display action: closure, # Action to perform --success: string, # Success message --error: string # Error message ] { print -n $'($message) ' # ASCII spinner frames let frames = ['⠋', '⠙', '⠹', '⠸', '⠼', '⠴', '⠦', '⠧', '⠇', '⠏'] # Start the spinner in the background let spinner_pid = job spawn { mut i = 0 print -n (ansi cursor_off) loop { print -n (ansi cursor_left) print -n ($frames | get $i) sleep 100ms $i = ($i + 1) mod ($frames | length) } } # Run the action and capture result let result = try { do $action { success: true } } catch { { success: false } } # Stop the spinner job kill $spinner_pid print "\r \r" # Show appropriate message if $result.success { print ($success | default '✓ Done!') } else { print ($error | default '✗ Failed!') exit 1 } } ``` # User-Facing Changes <!-- List of all changes that impact the user experience here.
