| .TP |
| .B \-h, \-\-help |
| Print this help and exit. |
| .RS |
| .RE |
| .TP |
| .B \-v, \-\-version |
| Print version and exit. |
| .RS |
| .RE |
| .TP |
| .B \-\-desc=\f[I]desc\f[] |
| str, optional. |
| Prefix for the progressbar. |
| .RS |
| .RE |
| .TP |
| .B \-\-total=\f[I]total\f[] |
| int or float, optional. |
| The number of expected iterations. |
| If unspecified, len(iterable) is used if possible. |
| If float("inf") or as a last resort, only basic progress statistics are |
| displayed (no ETA, no progressbar). |
| If \f[C]gui\f[] is True and this parameter needs subsequent updating, |
| specify an initial arbitrary large positive number, e.g. |
| 9e9. |
| .RS |
| .RE |
| .TP |
| .B \-\-leave |
| bool, optional. |
| If [default: True], keeps all traces of the progressbar upon termination |
| of iteration. |
| If \f[C]None\f[], will leave only if \f[C]position\f[] is \f[C]0\f[]. |
| .RS |
| .RE |
| .TP |
| .B \-\-ncols=\f[I]ncols\f[] |
| int, optional. |
| The width of the entire output message. |
| If specified, dynamically resizes the progressbar to stay within this |
| bound. |
| If unspecified, attempts to use environment width. |
| The fallback is a meter width of 10 and no limit for the counter and |
| statistics. |
| If 0, will not print any meter (only stats). |
| .RS |
| .RE |
| .TP |
| .B \-\-mininterval=\f[I]mininterval\f[] |
| float, optional. |
| Minimum progress display update interval [default: 0.1] seconds. |
| .RS |
| .RE |
| .TP |
| .B \-\-maxinterval=\f[I]maxinterval\f[] |
| float, optional. |
| Maximum progress display update interval [default: 10] seconds. |
| Automatically adjusts \f[C]miniters\f[] to correspond to |
| \f[C]mininterval\f[] after long display update lag. |
| Only works if \f[C]dynamic_miniters\f[] or monitor thread is enabled. |
| .RS |
| .RE |
| .TP |
| .B \-\-miniters=\f[I]miniters\f[] |
| int or float, optional. |
| Minimum progress display update interval, in iterations. |
| If 0 and \f[C]dynamic_miniters\f[], will automatically adjust to equal |
| \f[C]mininterval\f[] (more CPU efficient, good for tight loops). |
| If > 0, will skip display of specified number of iterations. |
| Tweak this and \f[C]mininterval\f[] to get very efficient loops. |
| If your progress is erratic with both fast and slow iterations (network, |
| skipping items, etc) you should set miniters=1. |
| .RS |
| .RE |
| .TP |
| .B \-\-ascii=\f[I]ascii\f[] |
| bool or str, optional. |
| If unspecified or False, use unicode (smooth blocks) to fill the meter. |
| The fallback is to use ASCII characters " 123456789#". |
| .RS |
| .RE |
| .TP |
| .B \-\-disable |
| bool, optional. |
| Whether to disable the entire progressbar wrapper [default: False]. |
| If set to None, disable on non\-TTY. |
| .RS |
| .RE |
| .TP |
| .B \-\-unit=\f[I]unit\f[] |
| str, optional. |
| String that will be used to define the unit of each iteration [default: |
| it]. |
| .RS |
| .RE |
| .TP |
| .B \-\-unit\-scale=\f[I]unit_scale\f[] |
| bool or int or float, optional. |
| If 1 or True, the number of iterations will be reduced/scaled |
| automatically and a metric prefix following the International System of |
| Units standard will be added (kilo, mega, etc.) [default: False]. |
| If any other non\-zero number, will scale \f[C]total\f[] and \f[C]n\f[]. |
| .RS |
| .RE |
| .TP |
| .B \-\-dynamic\-ncols |
| bool, optional. |
| If set, constantly alters \f[C]ncols\f[] and \f[C]nrows\f[] to the |
| environment (allowing for window resizes) [default: False]. |
| .RS |
| .RE |
| .TP |
| .B \-\-smoothing=\f[I]smoothing\f[] |
| float, optional. |
| Exponential moving average smoothing factor for speed estimates (ignored |
| in GUI mode). |

| [default: 0.3]. |
| .RS |
| .RE |
| .TP |
| .B \-\-bar\-format=\f[I]bar_format\f[] |
| str, optional. |
| Specify a custom bar string formatting. |
| May impact performance. |
| [default: \[aq]{l_bar}{bar}{r_bar}\[aq]], where l_bar=\[aq]{desc}: |
| {percentage:3.0f}%|\[aq] and r_bar=\[aq]| {n_fmt}/{total_fmt} |
| [{elapsed}<{remaining}, \[aq] \[aq]{rate_fmt}{postfix}]\[aq] Possible |
| vars: l_bar, bar, r_bar, n, n_fmt, total, total_fmt, percentage, |
| elapsed, elapsed_s, ncols, nrows, desc, unit, rate, rate_fmt, |
| rate_noinv, rate_noinv_fmt, rate_inv, rate_inv_fmt, postfix, |
| unit_divisor, remaining, remaining_s, eta. |
| Note that a trailing ": " is automatically removed after {desc} if the |
| latter is empty. |
| .RS |
| .RE |
| .TP |
| .B \-\-initial=\f[I]initial\f[] |
| int or float, optional. |
| The initial counter value. |
| Useful when restarting a progress bar [default: 0]. |
| If using float, consider specifying \f[C]{n:.3f}\f[] or similar in |
| \f[C]bar_format\f[], or specifying \f[C]unit_scale\f[]. |
| .RS |
| .RE |
| .TP |
| .B \-\-position=\f[I]position\f[] |
| int, optional. |

| bool, optional. |
| If true, will treat input as newly elapsed iterations, i.e. |
