Progress::Any::Output::TermProgressBarColor - Output progress to terminal as color bar
This document describes version 0.246 of Progress::Any::Output::TermProgressBarColor (from Perl distribution Progress-Any-Output-TermProgressBarColor), released on 2019-07-30.
use Progress::Any::Output; # use default options Progress::Any::Output->set('TermProgressBarColor'); # set options Progress::Any::Output->set('TermProgressBarColor', width=>50, fh=>\*STDERR, show_delay=>5);
THIS IS AN EARLY RELEASE, SOME THINGS ARE NOT YET IMPLEMENTED E.G. STYLES, COLOR THEMES.
This output displays progress indicators as colored progress bar on terminal. It produces output similar to that produced by Term::ProgressBar, except that it uses the Progress::Any framework and has additional features:
colors and color themes
template and styles
displaying message text in addition to bar/percentage number
wide character support
XXX option to cleanup when complete or not (like in Term::ProgressBar) and should default to 1.
Instantiate. Usually called through
freq => num
Limit the frequency of output updating. 0 means no frequency limiting (update output after every
A positive number means to update output when there has been that amount of difference in position since last
update(). For example, if
freqis 10 and the last
update()was at position 5, then the next output update will be when position is at least 15.
A negative number means to update output when time has passed that amount of absolute value (in seconds). For example, if
freqis -3 and the last
update()was 1 second ago, then the next output update will not be until the next two seconds has passed.
By default undef, in which case Progress::Any will use the default -0.5 (at most once every 0.5 seconds).
wide => bool
If set to 1, enable wide character support (requires Text::ANSI::WideUtil.
width => INT
Width of progress bar. The default is to detect terminal width and use the whole width.
color_theme => STR
Not yet implemented.
Choose color theme. To see what color themes are available, use
style => STR
Not yet implemented.
Choose style. To see what styles are available, use
list_styles(). Styles determine the characters used for drawing the bar, alignment, etc.
template => str
See fill_template in Progress::Any's documentation. Aside from conversions supported by Progress::Any, this output recognizes these additional conversions:
%bto display the progress bar (with width using the rest of the available width),
%Bto display the progress bar as well as the message inside it. You can also enclose parts of text with "<color RGB>" ... "</color>" to give color.
The default template is:
<color ffff00>%p</color> <color 808000>[</color>%B<color 808000>]</color><color ffff00>%e</color>
fh => handle (default: \*STDERR)
Instead of the default STDERR, you can direct the output to another filehandle e.g. STDOUT.
show_delay => int
If set, will delay showing the progress bar until the specified number of seconds. This can be used to create, e.g. a CLI application that is relatively not chatty but will display progress after several seconds of seeming inactivity to indicate users that the process is still going on.
Can be called to reset the timer that counts down to show progress bar when
show_delay is defined. For example, if
show_delay is 5 seconds and two seconds have passed, it should've been 3 seconds before progress bar is shown in the next
update(). However, if you call this method, it will be 5 seconds again before showing.
freq to e.g. -0.1 or -0.05. The default
freq, when unset, is -0.5 which means to update output at most once every 0.5 second.
Bool. Can be used to force or disable color. See Color::ANSI::Util.
Integer. Can be used to override color depth detection. See Color::ANSI::Util.
Integer. Can be used to override terminal width detection.
Bool. Forces disabling or enabling progress output (just for this output).
In the absence of PROGRESS_TERM_MESSAGE and PROGRESS, will default to 1 if filehandle is detected as interactive (using
Bool. Forces disabling or enabling progress output (for all outputs).
