Usage: $script_name [options] -c <current_num> $script_name [options] <current_num> $script_name <current_num> Options: -a : Accessibility mode: only output ASCII. (Also enabled if variable '$a11y_variable' set). -b : Display current value as space if zero, rather than lowest 'value' of theme. -c <num> : Current value of your indicator. -d : Enable debug output. -e <int> : Number of decimal places to use for accessibility mode (default=$default_decimal_places). -h : Show this help. -i : Invert colour scheme (rating themes only). -l : List available themes. If '-t' also specified, show all values for specified theme. -m <num> : Minimum value (default=$min_default). -n : Supress output of newline character. -p : Permissive mode - if current value out of bounds, set it to the nearest bound (min or max). -q : Suppress messages (requires '-t'). -r : Reverse 'direction' of display (rating theme only). -t <theme> : Name of theme (default=$theme_default). -u <chars> : Specify a user theme (2 or more values). -w <int> : Width of rating theme (default=$width_default). -x <num> : Maximum value (default=$max_default). Examples: # Display character representing 27% using default theme. $script_name 27 # As above. $script_name -c 27 # Example showing floating-point and negative values. $script_name -c 1.100001 -m -5.00234 -x 2.71828 -t dice_6 # Use accessibility mode to display a percentage value # (rounded to nearest percentage) $script_name -m -22.613 -x 5.00212 -c 0.10203 -a -e 0 # Display value using a "rating theme" (displayed left-to-right). $script_name -c 83 -t stars_2 # Display right-to-left inverted "rating theme". $script_name -c 60 -t diamonds_2 -ri # Display all glyphs in 'solid_numbers_a_10' theme. $script_name -l -t solid_numbers_a_10 # Display a user-specified rating theme 10 glyphs wide. $script_name -c 666.321 -m -273.15 -x 1370 -u "· ☢" -w 10 # A multi-element user theme (this prints 'e'). $script_name -c 50 -u "a b c d e f g h i j" Notes: - Arguments of type "<int>" denote an integer value, whereas arguments of type "<num>" denotes either an integer or a floating-point number. - The final '_<number>' in a theme name denotes the number of glyphs in it. - "Rating themes" are those with only 2 values. - The <chars> argument to '-u' must contain space-delimited characters.
