.TP
.B \-v, \-\-version

.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=\f[I]leave\f[]
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=\f[I]disable\f[]
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=\f[I]dynamic_ncols\f[]
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).
Ranges from 0 (average speed) to 1 (current/instantaneous speed)
[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.
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.
Specify the line offset to print this bar (starting from 0) Automatic if
unspecified.
Useful to manage multiple bars at once (eg, from threads).
.RS
.RE
.TP
.B \-\-postfix=\f[I]postfix\f[]
dict or *, optional.
Specify additional stats to display at the end of the bar.
Calls \f[C]set_postfix(**postfix)\f[] if possible (dict).
.RS
.RE
.TP
.B \-\-unit_divisor=\f[I]unit_divisor\f[]
float, optional.
[default: 1000], ignored unless \f[C]unit_scale\f[] is True.
.RS
.RE
.TP
.B \-\-write_bytes=\f[I]write_bytes\f[]
bool, optional.
If (default: None) and \f[C]file\f[] is unspecified, bytes will be
written in Python 2.
If \f[C]True\f[] will also write bytes.
In all other cases will default to unicode.
.RS
.RE
.TP
.B \-\-lock_args=\f[I]lock_args\f[]
tuple, optional.
Passed to \f[C]refresh\f[] for intermediate output (initialisation,
iterating, and updating).
.RS
.RE
.TP
.B \-\-nrows=\f[I]nrows\f[]
int, optional.
The screen height.
If specified, hides nested bars outside this bound.
If unspecified, attempts to use environment height.
The fallback is 20.
.RS
.RE
.TP
.B \-\-delim=\f[I]delim\f[]
chr, optional.
Delimiting character [default: \[aq]\\n\[aq]].
Use \[aq]\\0\[aq] for null.
N.B.: on Windows systems, Python converts \[aq]\\n\[aq] to
\[aq]\\r\\n\[aq].
.RS
.RE
.TP
.B \-\-buf_size=\f[I]buf_size\f[]
int, optional.
String buffer size in bytes [default: 256] used when \f[C]delim\f[] is
specified.
.RS
.RE
.TP
.B \-\-bytes=\f[I]bytes\f[]
bool, optional.
If true, will count bytes, ignore \f[C]delim\f[], and default
\f[C]unit_scale\f[] to True, \f[C]unit_divisor\f[] to 1024, and
\f[C]unit\f[] to \[aq]B\[aq].
