| 2 | * A test helper to exercise the progress display. |
| 3 | * |
| 4 | * Reads instructions from standard input, one instruction per line: |
| 5 | * |
| 6 | * "start <total>[ <title>]" - Call start_progress(title, total), |
| 7 | * Uses the default title of "Working hard" |
| 8 | * if the " <title>" is omitted. |
| 9 | * "progress <items>" - Call display_progress() with the given item count |
| 10 | * as parameter. |
| 11 | * "throughput <bytes> <millis> - Call display_throughput() with the given |
| 12 | * byte count as parameter. The 'millis' |
| 13 | * specify the time elapsed since the |
| 14 | * start_progress() call. |
| 15 | * "update" - Set the 'progress_update' flag. |
| 16 | * "stop" - Call stop_progress(). |
| 17 | * |
| 18 | * See 't0500-progress-display.sh' for examples. |
